Abstract
This paper presents 10
critical ideas about assessment that, when placed into practice, can
significantly advance and add value to every academic professional's
work. Together, these ideas form a set of principles and practices whose
impact can be measured to provide a comprehensive picture of the
assessment culture in an organization. Each idea presented here is
supported by the literature and informed by the use of the idea in
practice. Key terms and schema relating to assessment are defined,
related resources are noted, and ways in which assessment can enhance
student learning and growth, enhance faculty performance, and improve
institutional effectiveness and quality in its collective learning
environment are shown. The ideas presented here fall within three
categories. The first category addresses vital issues in the
relationship between assessment and evaluation. Specific topics
addressed in this category are the role of measurement in assessment,
common misconceptions about assessment, using assessment to enhance
performance on an evaluation, and turning evaluation into assessment.
The second category deals with assessment values, practice and mindset.
Specific topics addressed in this category are key steps in the
assessment process, writing clear performance criteria, assessing
assessments, and self-assessment for growth. The third category deals
with conditioning and historical cultural norms in higher education that
prevent change toward an assessment culture. Specific topics addressed
in this category are the role of assessment in the mentoring process and
the assessment mindset. The paper closes with a brief description of
issues regarding cultural change that must be confronted when an
organization in higher education begins to embrace and implement these
ideas.
Introduction
During the last 15 years, Pacific Crest and its
associates has been coaching and mentoring faculty, programs, and
colleges on how to improve teaching, learning, instructional design,
mentoring, and effective use of technology and educational systems. A
major cornerstone in those efforts has been the effective use of
assessment. This paper presents 10 critical ideas about assessment that,
when placed into practice, advance and add value to every academic
professional’s work. Key terms and schema relating to assessment are
defined, additional resources are noted, and ways in which assessment
can enhance student learning and growth, enhance faculty performance,
and improve institutional effectiveness and quality in its collective
learning environment are shown.
There is a lot of very good news about assessment
over the last seven years. Assessment is not considered a fad anymore by
most college stakeholders. In reviewing the history of assessment, there
has been significant attitude change in the past two decades. During the
late 80’s few individuals in higher education knew of or were exposed to
assessment, the 90’s became the change decade, and now in the 21st
century assessment is being slowly embraced (Astin, 1993; Banta &
Associates, 2002). A very similar pattern occurred with total quality
management (TQM) in the business community. The effort towards
increasing quality closely parallels the assessment movement
in higher education. It took TQM over 20 years to make significant
cultural penetration into businesses where practices matched intent.
Similarly, when assessment comes up in campus discussions now it is not
whether assessment must be incorporated, but a matter of how, in what
areas, by whom, when and for what purpose.
A consistent issue that all colleges have about
assessment is deciding how to imbed assessment where opportunities are
most meaningful and valuable for the growth of its students, faculty,
staff, and self. Through discussions, research, practice, and community
events involving hundreds of faculty innovators, we have identified ten
key ideas in the use of assessment that educational professionals find
extremely beneficial in improving performance (Apple, 2005; Elger et
al., 2006; , "Pacific Crest Home Page", 2006; , "Scholars Community",
2006). These ideas are foundational for producing significant results
from assessment practice. In our collective experience, there is great
potential for obtaining increased buy-in and significant movement
towards an assessment culture when these ideas are extensively
implemented on a campus.
The ideas presented here fall within three
categories. The first category addresses vital issues in the
relationship between assessment and evaluation. The second category
deals with assessment values, practice and mindset. The third category
deals with conditioning and historical cultural norms in higher
education that present barriers to easy change towards an assessment
culture. Finally, it is important to understand how these ideas relate
to the process of change so that transformation towards an assessment
culture can be facilitated.
The ten ideas below will be discussed by describing
each one’s meaning, identifying issues that need to be addressed, noting
ways for effective implementation, and finally offering a means for
measuring its impact for improving assessment.

10. Evolving an assessment mindset |
The shift to assessment
culture within an evaluation culture requires several key
ingredients |
Evaluation as a Strong Cultural
Value of Higher Education
Before we start to describe each idea, it is
important to characterize the culture of Higher Education and its key
values and practices that distinguish it from other institutions. Higher
Education ensures through its disciplines that knowledge which is
created and disseminated is of high quality. Only through this knowledge
being of highest quality can other segments of society use this
knowledge with some reliability (Duderstadt, 2000). In addition, the
process of obtaining access to the fraternity of higher education
(graduate degrees) requires that a person acquire a set of values and
practices that are highly valuable but often narrow in scope. These
include how to survive given enormous amounts of evaluative feedback
through coursework, research, peer publications, committee reviews,
teaching experiences, etc. This type of feedback prevalent in the
culture tends to find fault in what you learn, what you say, how you
perform, and what you produce. Because of this environment, many people
begin to norm their behaviors by making sure that public performance is
well rehearsed, learning is done individually and in private, only
"final" products are presented, and that most efforts are individual
because this is how they get credit (Tierney & Rhoads, 1993).
Thus, academic culture develops future faculty as
individuals who can construct knowledge in the discipline, process
disciplinary journals and resources, and make strong judgments to the
quality of this disciplinary knowledge according to their own
understanding of this knowledge. In addition, future faculty develop
significant skills such that they can perform the research process
effectively within the domains of their disciplines through established
methods. Within these roles the acceptance of evaluation is a must and
the evaluation of others expected (Mills & Hyle, 1999).

AREA 1: Relationships between
Assessment and Evaluation |
Over the past 15 years, our research has uncovered
numerous relationships between assessment and evaluation. However, in
order to talk about assessment and evaluation effectively, it is
important to first clarify use of language since there are as many
definitions of assessment and evaluation within the literature as there
are about any two words used in Higher Education. Furthermore, both are
integrally related to the process of measurement as described at the
beginning of the next section. The definitions and purpose for terms
listed in the table below have evolved as extremely useful way to
differentiate and clarify the use of each term and will be used as shown
throughout this work.

1. Role of Measurement
within Assessment and Evaluation
Measurement is a process that is often poorly
understood. First and foremost assessment is not just measurement. The
practice of measurement of teaching and learning throughout Higher
Education holds significant opportunity for improvement (ref).
Nonetheless, in either quality assessment or quality evaluation
processes, one must always collect quality data to understand at what
level the performance has been delivered. From this data, an
assessment can be produced to help improve the performance. Also from
this data an evaluation can be made to determine the acceptability of
the performance. In either case, it is critical that the areas of
quality in the performance are clearly stated (see idea number 6,
writing clear performance criteria) so that one can identify what
really matters and then locate or construct the means to accurately
and reliably measure those areas. In order to produce the needed
analysis in assessment or the judgment in evaluation, it is critical
that the measurement is done in timely, effective and meaningful ways
where the participants in the process can be assured that the data is
reliable, targeted, and comprehensive in order the carry out the
intended purpose (Stiggins, 1987).
Among the community of scholars currently advancing
this knowledge area are the Evaluation Centers at colleges like
Washington State University and Western Michigan University, those
involved in placement of individuals like ACT and ETS. From this
community, tools to measure many areas of performance critical to
student learning in higher education have already been developed (Faculty
Guidebook: A Comprehensive Tool for Imrpoving Faculty Performance,
2005; Hatry, Houten, Plantz, & Taylor, 1996; Schrock, 2006).
2. False Assumptions about
Assessment
There are several key assumptions that many
educators have made about assessment that make it very difficult for
them to elevate the use of assessment and its quality in daily
practice.
Assumption 1: A need for improvement implies poor
quality. Within an evaluation culture, if someone is working to get
better it is assumed that they are sub-standard. For example, a
faculty member who is recommended to go to a teaching workshop implies
that they are not teaching well enough. Once it is understood that
everyone can improve and that stating a need for improvement implies
that someone is committed to making that improvement then areas for
improvement become a positive sign and not a negative stigma. An area
for improvement is very much different than a weakness, but people
frequently interchange these words.
Assumption 2: High quality implies no need for
improvement. This assumption is almost the converse of assumption one.
Star performers have found that improving all areas of performance is
productive in advancing overall performance, not just focusing on the
least effective areas (reference would help here). The focus at any
point in time should be in the area that can contribute to the
greatest growth. Sometimes the camera should be on a strength, because
you want to understand better how this strength works and why it is
contributing so much to a performance. At other times the camera
should be on an area where you can see that you are being held back
from achieving the level of performance you would like. Thus, it is
important not to bias the selection of focus away from strengths
because they are equally important to areas for improvement.
Assumption 3: The person receiving feedback will
know how to make use of the feedback to improve. For example, most
faculty believe that students are used to getting evaluative feedback
and therefore know what they need to improve to meet a benchmark.
However, most people who get feedback are not capable using it
effectively for two major reasons. First, they are not emotionally
prepared to take an evaluation and transform it into an assessment
(see turning evaluation into assessment) (need reference). Second, and
more importantly, the analysis skills for the given context are nearly
always beyond the performer’s skill set to provide meaning and
direction for improving future performance. For example, in a
composition course, students who get feedback on their paper see the
issues but have little clarity of what to change in their writing
process to make this improvement. Therefore, it is important to
understand that the assessor needs not only to provide feedback on how
to improve the content, but also how to improve the process.
These ideas are echoed by Entwistle when discussing
faculty development to improve student learning. "Evidence on
conceptual change suggests that, first, the individual has to perceive
a reason for change. If the existing conception still feels adequate
[high quality no need for improvement] and comfortable, change is
unlikely. A variety of experiences have to be provided which both
challenge existing conceptions and suggest interesting alternative
conceptions [suggested improvement does not mean low quality in
current performance]. But these experiences have to be carefully
managed within an encouraging and supportive climate. The experiences
also have to be designed to fit the previous knowledge and learning
habits of the learners involved [such that they can make use of the
feedback]" (Entwistle, 1995).
3. Using Assessment to
Advance Performance in an Evaluation
A very important relationship between assessment
and evaluation is the way in which evaluation can create motivation
for assessment. Everyone wants to perform well, and when there are
well-defined means in place to determine level of performance, the use
of assessment to continually improve performance against these means
in preparation for an existing evaluation is a very motivating force.
Now, it is important to realize that the assessor
cannot drive the relationship. Despite the fact that the assessor
wants to assist in increasing the performance of the assessee, a
hidden motivation to help themselves is often present as well. For
example, in the teacher-student relationship, most often the faculty
member desires to improve the student’s performance so they get strong
reviews as an educator. The department chair wants their junior
faculty to grow and prosper so they get tenure and strengthen the
department. The college wants their programs to get better so they are
reviewed as world-class. The advisor of the Ph.D. candidate wants
their mentee to pass their dissertation defense and expand their
community of established expertise. In each case, the person who is in
a position to provide assessment to help improve performance in the
evaluation process also has a stakeholder interest in the results of
the evaluation. If these assessment relationships are led by the
assessor rather than the assessee, this leads to force-fed assessment,
or the desire of the mentor/teacher/administrator wanting success more
than the mentee. When this occurs it severely reduces the potential
for growth of the assessee because long term behavioral change comes
from within and not from the outside. Effective, internalized change
cannot be mandated (Fishbein & Ajzen, 1975; , "Recruiting Supportive
Coaches: A Key to Achieving Positive Behavioral Change", 2003) (need
additional refs). Thus, it is much more effective to use a mentoring
process to set up the desire for assessment and then let the assessee
play the central role in the assessment process where they initiate
and implement assessment. In this way, preparation to perform in
evaluations will by much more effective due to internal forces driving
the desire to perform well in the evaluation process.
4. Turning Evaluation into
Assessment
The fundamentals of turning evaluation into
assessment are to ask more of the feedback, respond non-emotionally to
the feedback, and to structure the feedback in three forms –
strengths, improvements, and insights.
Asking more of the feedback: as informed by best
practices in the literature, over the years we have synthesized the
information to develop many profiles and performance measures such as
the profile of a self-grower, quality learner, and a quality faculty
member as well as performance measures for level of self-growth, level
of learner performance, and level of educator performance (Collins &
Apple, 2003; Krumsieg & Baehr, 2000; Nancarrow, 2003) (have profile
refs, need refs for each performance measure). In each of these
profiles is the ability to effectively reflect and self-assess in
order to move up the scale and reach the highest levels of
performance. In other words, quality self-assessment is a must.
Therefore, the opportunities that each person has of using evaluative
feedback as the basis for transforming this feedback into assessment
is a critical factor in becoming a "star" performer. In order to do
this, one must view evaluative feedback as benchmark data to use and
expand upon within a flexible, proactive self-assessment process to
improve performance.
Non-emotional response to the feedback: most
individuals who receive evaluative feedback are not ready to use this
feedback for growing future performance because they are too
emotionally wrapped up in how well they just performed. Responses to
evaluative feedback may be to ignore it in the case of satisfactory
performance, or to feel that the evaluation process was flawed and
that it was unfair in certain aspects in the case of unsatisfactory
performance. However, if the feedback is taken and analyzed through
the lens of assessment, evaluative feedback can be useful.
Furthermore, by focusing on performance rather than performer it
becomes easier for the evaluator to provide more information and
analysis and for the performer to use this feedback since it is
removed from emotionally laden ties to the performing individual.
Organizing feedback into strengths, improvements,
and insights: evaluative feedback can identify strengths and help
build those strengths through analyzing the reasons behind why those
strengths contributed to the performance, identify areas for
improvement and lead to action plans for achieving those improvements,
and provide insight about the underlying elements of the performance
that has just been evaluated. By organizing evaluative feedback in
this way, "the evaluation no longer serves as a punitive measure or a
justification document, but instead serves as a … useful tool by which
the performer’s progress is measured within the assessment paradigm
(Watson, 2005)."
|
Area 2: Assessment Practice
|
Current practice of assessment can often be enhanced
by recognizing and incorporating some commonly missed fundamental tools,
concepts, and alignment with basic principles. The most important areas
to consider include writing clear performance criteria, evolving an
assessment mindset, and importance of assessing assessments.
5. Key Steps in the
Assessment Process
As learned through assessing thousands of different
assessment processes and systems over the last 15 years, effective
assessment always involves several common steps (Apple & Baehr, 2005).
Observation has shown following to be the most frequently missing
steps: ensuring the assessment request and purpose come from the
assessee, establishing the rules of engagement between the assessor
and assessee, ensure assessment is delivered only in the desired
areas, and formatting feedback in a structured manner for the assessee.
The first step is determining who has requested the
assessment and for what purpose. Clearly, we understand that no
individual can control the behaviors of someone else. Thus, assessment
must be learner-centered around the assessee, where they desire to
make changes for a desired outcome. Whether an observation that a
change could be beneficial originates with the mentor or the assessee,
the assessee must want and agree to the purpose of the assessment (Chism,
1999).
Another critical step that is often skipped is the
establishing of rules of engagement between the assessor and assessee.
This helps to create an atmosphere of trust within the assessment
process and relationship. Creating simple guidelines for collecting
assessment data and delivering the feedback lead conditions where the
feedback can be used effectively to produce an enhanced future
performance. Conditions to consider include setting proper boundaries
and conventions, agreeing upon the way in which the performance will
be viewed, and finally, how and when the feedback will be delivered (Arreola,
1995; Chism, 1999).
Checking that the criteria used for the assessment
align closely with the focus areas chosen by the assessee is another
step that is often skipped or poorly addressed. This may arise from a
situation where the assessor feels they are in a better position to
determine what the assessee needs and thus uses their values and
expertise to make these decisions. However, the truth is that the
person or program being assessed is actually in a much better position
to know what they need. Here are the conditions that must exist for
the criteria to be valuable; the assessee must a) want to improve in
the areas subject to the criteria, b) have an opportunity to improve,
and c) feel they can benefit significantly from the assessment because
the criteria are important to the overall performance. The assessor
needs to understand that their role is one of servant leadership,
often providing a recommended list of potential criteria, but must let
the assessee chose the criteria that meets the above conditions
(Angelo & Cross, 1993).
Finally, assessment feedback is often left
underutilized despite intentions to bring higher levels of
understanding, comprehension, and meaning to that feedback. As
mentioned in idea number four (turning evaluation into assessment),
organizing feedback into three forms: strengths, areas for
improvement, and insights, is a simple but effective way to elevate
the quality and usability of assessment feedback. The first area of
analysis is clarifying the strengths in a performance as to their
value and in how those strengths were produced. Often, individuals or
programs produce value, but don’t realize it and are unaware of how
they did it. If a future performance is going to leverage off of
demonstrated strengths, we need to understand them. The next area of
analysis is the production of well developed action plans that
describe how the most important improvements are going to be made.
This is where the assessor "earns their money" or produces significant
value. Their expertise can provide much better direction and more
quickly develop practices to gain these improvements. Finally, since
assessing something allows you to be in a very special learning
situation, you can share your new understanding and learning with the
assessee through well developed insights (Gardner, 1997; Parker,
Fleming, Beyerlein, Apple, & Krumsieg, 2001; Wasserman & Beyerlein,
2005).
6. Writing Clear Performance
Criteria
Fundamental to quality assessment and evaluation is
having clear performance criteria. These criteria form the foundation
for building and improving performance in any type of assessment
setup. Simply put, performance criteria are the areas of quality
encompassing an action or task to be performed. Another definition
might be "a description of the quality requirements" during and as a
result of a performance (Faculty Guidebook: A Comprehensive Tool
for Imrpoving Faculty Performance, 2005; Rogers, 2002; , "What is
a performance criterion?" 2006).
The writing of performance criteria is one of the
more difficult tasks for faculty and staff. It requires skills in
identifying and prioritizing the key qualities that are sought in a
performance or a set of performances, an analysis of these qualities,
seeing the pattern in the analysis, visualizing the performance, and
finally writing the clear statement of what this performance looks
like. Additionally, the performance criteria should be described in an
explicit and motivating way such that buy-in to these challenging
expectations is generated for all stakeholders (Airasian, 1991; Arter
& McTighe, 2001).
Performance criteria are a must for improving and
document performances such as learning activities, courses, and
programs. They are also critical for administrators, determining the
level of institutional effectiveness, effective faculty tenure and
promotion process, and accreditation. The performance criteria provide
an excellent foundation for identifying a set of measures that really
matter and correlate strongly to the integrated performance desired.
The more performance criteria are imbedded in daily practices, the
stronger the assessment culture evolves and the more likely effective
feedback will be both generated and integrated for improving future
performance.
7. Assessing Assessments
Any person involved in assessment knows that
assessment is used to advance performance in many areas of educational
practice and processes. The one practice/process that rarely gets
assessed is assessment. It is critical for assessment systems,
processes, and practices get assessed on a frequent basis to improve
their performances. The current quality of design, implemented
processes, and individual practices can be improved significantly. The
identification of clear criteria and measures for assessing
assessments with timely data collection and analysis can provide
feedback that can be incorporated in improving the performances of the
assessments.
The assessors and the designers of assessment
systems and processes must initiate the desire and mechanisms for this
assessment to occur. The assessment experts are normally in control of
the assessment systems and processes and are the least likely to
initiate the improvement of these assessment of assessments. A
practice that is very effective is for the assessee to assess the
assessment they receive.
8. Self-assessment to
Produce Self-Growth
The enriched learning environment in higher
education is based in an assessment culture where each person wants to
improve and practices self-assessment as a means of mentoring
self-growth. This basically requires support for stopping to take a
few minutes after each performance – teaching a class period,
finishing up a course, designing a new activity, writing a proposal,
facilitating a committee meeting, etc. to assess the performance to
see how future performance can be improved. The pressures of
performance (doing) has increased over the last ten years and as a
result leaves even less time to be reflective and the discipline to
practice self-assessment. This is the fundamental basis for shifting a
culture to self-growth.
|
Area 3: Higher Education
Culture and Impact on Assessment |
The shifting of a Higher Education institution
towards a continuous quality improvement environment is a non-trivial
transformational change. Many forces are lining up to encourage,
challenge, and support this change such as regional and professional
accreditation, state legislature, professional association, funding
sources, and students. There are many things to consider in expanding
assessment systems, processes, and practices within Higher Education.
Higher Education has conditioned faculty with years
of experience for both receiving and providing evaluative feedback.
Faculty are familiar with giving (or getting) feedback to improve
content to meet a benchmark – not in giving (or getting) feedback on
improving the process. A significant value in Higher Education is being
critical of thinking and knowledge of others. DeBono called this the
Intelligence Trap – it is much easier to find fault in others, their
ideas, and performance than putting oneself in a risky venture of
presenting your own ideas, trying out new innovative practices, or
present new research or ways of improving something established. A quick
inventory of practices – course grades, tenure and promotion, student
evaluations, peer review of research proposal grants, publishing
critique, evaluation of text materials, and merit pay.
9. Role of Assessment in
Mentoring
The valuing of growth in performance is fundamental
in a mentoring relationship. The key role of a mentor is to help
improve future performance by proving quality feedback. The key
question then is - If you want to improve future performance do you
need feedback on content of the current performance or process of
current performance? This is the issue – need to intervene on process
and not content. The assessment feedback is associated with how to
improve the performance and not on content of the performance. For
example, in the writing process, often feedback is given on how to
improve a certain paper that is being written versus looking at the
issues behind the performance and use this understanding of how to
improve their writing process.
10. Evolving an Assessment
Mindset within an Evaluation Culture
The whole mindset of assessment shifts philosophy
of how feedback is to be given and received. Evaluation is an
important process and should improve also, but most of the time when
feedback is really being structured for helping improving performance,
the feedback still comes across as evaluative. Most people who give
feedback do not differentiate evaluative versus assessment feedback
and only really differentiate it when they receive the feedback. It is
important to set up conventions and practices that create an
assessment culture. One of the most important reasons is that faculty
are familiar with giving (or getting) feedback to improve content to
meet a benchmark – not in giving (or getting) feedback on improving
the process. Language becomes important, understanding other’s values
and perspectives is fundamental, and finally wanting others to improve
performance must be an important goal.
The Theory and Practice of
Facilitating Cultural Change
Fundamentally, shifting to an assessment culture
requires a significant transformational change. The theory of change and
how to facilitate change in Higher Education is really important for
creating an assessment culture. Inside facilitators are at high-risk
because it implies that they are better than their peers and thus come
across as an outsider. The facilitation works much better from outside
where the challenges and the discharge of issues leaves the organization
the ability to move forward, key change agents as mentors, and a
community of practice to evolve.
Conclusions
These ten ideas about assessment form
a critical core that, when put into practice, can make significant value
and impact for all professionals working in academia. A key element of
these critical ideas, as a set, is that together they empower
participants and accelerate self-growth. However, this is only true when
considering assessment as a process used to improve future performance
as defined here. When assessment is based on careful and structured
analysis of well-developed measures articulating high performance
expectations, performance can increase dramatically when that assessment
has been or can be separated from evaluation. Furthermore, these effects
are multiplied when both the process for assessment and the criteria on
which the assessment is based are clear. Both of these are necessary
conditions for the academic professional to effectively utilize
self-assessment and, additionally, assess the value of the assessment
feedback they receive to maximize performance gains. Finally, it should
be recognized that placing these ideas into practice does take
significant effort and involves a transition in mindset that can be
challenging. This is true from the institutional level down to the
individual level.
