Assessment principles and practices—Quality assessments in a digital age
Overview
Table of contents
This resource has been designed to have many routes through, depending on the interests and needs
of the reader. The following table of contents is intended only as a reference list of all the chapters
rather than a suggested order in which they should be read. We would encourage you to start with
the chapter on Using this resource, to understand how to navigate to the sections which are most
important to you.
Foreword
“Everything that can be counted does not necessarily count; everything that counts cannot
necessarily be counted.
— (Albert Einstein/William Cameron 1963)
“Clearly, if the other criteria are less reliable than the examinations, greater reliance on them
will lead to less reliable selection decisions.
— (Mike Cresswell 1986)
These two quotes indicate the scope of the challenge that we face with assessment. Many of the
objectives for an International Baccalaureate (IB) education are not easy to assess, but without
detailed assessments of our learners, important decisions that will affect their lives will be made on
less fair and reliable grounds.
IB programmes are taught in over 140 countries by schools representing a wide variety of educational
contexts and traditions. In some of these contexts, the philosophy and approaches adopted by the IB
in assessing their students will seem familiar, while to others, the system might seem mysterious and
In this document, we are seeking to explain the principles the IB has adopted to make sure that the
assessment we undertake is meaningful, fair and in the best interest of the students involved.
obscure.

Assessment principles and practices—Quality assessments in a digital age
Overview
Such clarity is even more important during a period of change, and the impact of technology
on education, including assessment, will continue to be felt over the next decade. We strongly
believe that technology should support assessment and the move towards computerized on-screen
examinations will not change our principles; but it may open up new possibilities in turning these
principles into practices. More details on this can be found in the chapter on Assessment using
technology.
We believe that it is important that everyone in the IB community understands how our external
assessment process works, what its strengths and limitations are, and the reasons why decisions are
taken. Increased transparency can only lead to better understanding and ultimately a better education
for our students. By using the opportunities offered by on-screen resources, we hope to provide
teachers with a clear guide that is accessible but also contains the depth of information they need to
understand IB assessment.

Assessment principles and practices—Quality assessments in a digital age
Overview
All assessments are a balance between conflicting demands and many concerns about testing
processes fail to take this into account.
An example might be the tension between reducing the assessments burden and the risk of
candidates only having one opportunity to show what they can do.
For more information on this see the section on validity.
Need to balance between conflicting priorities
Another aspect of balance is the fact that the focus of the IB is to develop students through a holistic
programme of study, and we must reflect this in our approach to assessment. This means we should
make decisions about the impact on the overall programme, not a narrow focus on one subject,
discipline or assessment.
In order to understand the nature of the IB assessment philosophy and operation, it is necessary to
provide some background on the historical and theoretical development of assessment practice.
Many significant issues are only briefly touched upon, but it is important to highlight them as they
have a significant impact on current practice. For readers who wish to find out more, the academic
papers quoted in the text will make a suitable starting point for further investigation.
We started by recognizing the difficult task the IB sets itself; to focus on what is important to assess
and not what is easy. This is perhaps most eloquently expressed by Alec Peterson, the first Director
General of the IB:
“What is needed is a process of assessment which is as valid as possible, in the sense that it
really assesses the whole endowment and personality of the pupil in relation to the next
stage of his life, but at the same time sufficiently reliable to assure pupils, parents, teachers,
and receiving institutions that justice is being done. Yet such a process must not, by its
backwash effect, distort good teaching, nor be too slow, nor absorb too much of our scarce
educational resources.
— (Peterson 1971)
We hope the rest of this resource explains how we believe we can deliver on this challenging
objective and support the wider educational intentions of the International Baccalaureate in providing

a world class experience for its students. If you have further queries which are beyond the scope of

Why read this document?
Because assessment results have an impact on students’ lives
The majority of the content of this document refers to the way in which the IB assesses candidates
to award Diploma Programme (DP), Career-related Programme (CP) and the optional Middle Years
Programme (MYP) outcomes, which are then used by students to progress into further education or
work.
Like everything else, assessment is only a tool which can lead to positive or negative outcomes for
those being evaluated with them. As a teacher, parent or student, you are involved in assessments
and should understand the strengths, weaknesses and decisions that those offering and using
assessment need to make. Below are some of the common questions and comments we receive from
teachers and how this document will help answer them.
This is the heartfelt question that we often hear from teachers and students when faced with
external assessment. By reading this document you should understand the principles that drive our
“Why would the IB do that?”
assessment practices.
“It’s not fair sir, I needed a higher grade!”
For students, a great deal will depend on their examination results, such as university entrance and
future career; and they need to understand why decisions are made. Assessment is all about balancing
conflicting and competing demands and this document will help you to explain to students the wider
implications of bending the rules in their case, and maybe even convince them that their grade was
“fair”.
“I had not thought about it like that before.”
