Body of knowledge

Exam blueprint

The exam is assembled to these weights on every attempt. They are published before purchase because a blueprint you cannot see is not a blueprint.

Item counts are approximate. Each attempt draws a fresh form to the weights above, so the exact number of items per domain varies between attempts.

    1 lesson

    1. Locked.Paradigms, epistemology and the design stackLocked

      On completion you will be able to

      • [R] Describe the design stack — ontology, epistemology, methodology, methods — and locate a given decision at the correct level.
      • [R] Characterise positivism, post-positivism, interpretivism/constructivism, pragmatism and critical realism by their ontological and epistemological commitments.
      • [A] Identify the paradigm a described study actually enacts.
      • [An] Detect a mismatch between a study's declared paradigm and its design, and explain the mismatch.
      • [R] Distinguish deduction, induction and abduction and state what each licenses.
  2. Module 2

    F2

    1 lesson

    1. Locked.From topic to answerable questionLocked

      On completion you will be able to

      • [A] Label a given set of statements correctly as aim, objective, research question or hypothesis.
      • [C] Convert a topic into an answerable research question.
      • [An] Assess whether a research question is answerable by any design and identify why not.
      • [A] Match a question type to the design type it demands.
      • [R] Identify independent, dependent, control, moderator and mediator variables in a described study.
  3. Module 3

    F3

    1 lesson

    1. Locked.Quantitative designs and what they licenseLocked

      On completion you will be able to

      • [A] Classify a described study by its design features rather than its label.
      • [An] Determine what causal claim a given design can support.
      • [An] Distinguish a quasi-experiment from a single-group pre-post design.
      • [A] Identify the design threat most likely to defeat a described study.
      • [R] Describe the temporal structure of cohort, case-control, cross-sectional and longitudinal designs.
  4. Module 4

    F4

    1 lesson

    1. Locked.Sampling, measurement and instrumentsLocked

      On completion you will be able to

      • [A] Identify the sampling strategy in a described study and name its inferential consequence.
      • [A] Distinguish target population, sampling frame and achieved sample, and identify divergence.
      • [An] Explain why a described sample supports inference to a particular population, or to none.
      • [C] Operationalise a construct into measurable indicators and defend the operationalisation.
      • [An] Appraise survey items for wording, response format and ordering problems.
  5. Module 5

    F5

    1 lesson

    1. Locked.Validity, reliability, bias and confoundingLocked

      On completion you will be able to

      • [A] Assign a described threat to the type of validity it bears on.
      • [A] Name the specific internal-validity threat in a described study.
      • [An] Specify to what population, setting and time a result may be generalised.
      • [R] Explain why a measure can be reliable and invalid.
      • [An] State what a reported Cronbach's alpha does and does not license.
      • [An] Distinguish confounder, mediator, moderator and collider in a described causal structure.
  6. Module 6

    F6

    1 lesson

    1. Locked.Qualitative approaches and analysisLocked

      On completion you will be able to

      • [A] Identify which qualitative approach a described study is actually using.
      • [An] Explain why a described study is not the approach it claims to be.
      • [A] Select an approach appropriate to a question and its epistemological commitments.
      • [A] Construct a codebook and apply it consistently where the approach calls for it.
      • [An] Apply trustworthiness criteria rather than importing quantitative ones.
      • [R] Distinguish the four types of triangulation and state what each addresses.
  7. Module 7

    F7

    1 lesson

    1. Locked.Mixed methods, ethics in design, and stating limitsLocked

      On completion you will be able to

      • [R] Name the core mixed-methods designs and their sequence and priority.
      • [An] Determine whether a study described as mixed methods is integrated at all.
      • [A] Identify ethical issues arising from a design as distinct from its conduct.
      • [A] Distinguish limitations, delimitations and assumptions.

Assessment

How the exam works

The exam is closed-book and multiple choice. Each attempt draws a fresh form to the domain weights above, so no two attempts are the same paper and no answer key circulates. The pass mark is 70% and is fixed — there is no curve, no quota and no adjustment by cohort.

Scoring is immediate. You are shown your overall result and, for every item, the option you chose, the correct option and the reasoning behind it — whether you passed or not. A failed attempt may be retaken after 90 days. The wait exists so a retake is a second attempt at the material rather than a second attempt at remembering the paper.

Forms are assembled to the blueprint above or not at all: where a domain cannot yet be sampled to that standard, the exam declines to start rather than issue an unbalanced paper. Your material and progress are never affected, and there is no time limit on when you sit.

Passing candidates are issued a certificate with a verification code. Anyone can check that code on our public verification page without an account and without contacting us.

Certifying authority

Signed by Dr. Diana Nieves Castro, MD

CASRAI’s certification programme is academically and medically directed by Dr. Diana Nieves Castro, MD, Programme Director, who sets the syllabus and blueprint for this credential and signs every certificate issued under it.

CASRAI has maintained the terminology and reporting standards of research administration for over a decade. It assumed leadership of the CRediT contributor-roles taxonomy in 2014 and carried it through to adoption as ANSI/NISO Z39.104-2022, now in use by publishers, funders and institutions worldwide. This examination is drawn from that body of work.

What the credential certifies: that its holder passed the CASRAI examination for this course on the date shown, scored against the blueprint and pass mark published above — verifiable by anyone, permanently, from the code on its face.
