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.

      • By the end, the learner can:
      • Describe the defining methodological features of each principal review type and attribute each to the manual that governs it. [R]

      • Select a review type for a stated information need and defend the selection against at least two alternatives. [E]

    1 lesson

    1. Locked.Question formulation, frameworks and eligibility criteriaLocked

      On completion you will be able to

    1 lesson

    1. Locked.Registration: PROSPERO, OSF, and the scope decisionLocked

      On completion you will be able to

      • State PROSPERO's scope in its own terms and determine, for a given review, whether PROSPERO will accept it. [A]

      • Apply PROSPERO's timing rules to decide when in a project's life registration should occur. [A]

    5

    1 lesson

    1. Locked.Search design: concept structure, controlled vocabulary and free textLocked

      On completion you will be able to

      On completion you will be able to

      • Select databases and other sources appropriate to a question and justify each inclusion and each deliberate exclusion. [E]

    1 lesson

    1. Locked.Automation, machine learning and LLMs in screening and extraction: a contested areaLocked

      On completion you will be able to

      • Distinguish, in a specific proposed use, whether an automated tool is prioritising human review or replacing it, and explain why the distinction changes what must be justified. [An]
      • Specify, for a proposed use of automation, what must be pre-specified in the protocol and what must be reported. [A]
      • Evaluate a claim of tool performance against the requirements of the review in hand. [E]

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.

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.
