Once your items have passed through an initial round of edits, it is time for a content review committee to examine them. Remember that you should document the qualifications of your committee members, and if possible, recruit different people than those used to write the items or conduct other reviews.
In their chapter in Educational Measurement (4 th ed.), Cynthia Shmeiser and Catherine Welch explain that the primary function of the content review committee is to verify the accuracy of the items with regard to the defined domain, including content and cognitive classification of items. The committee might answer questions like:
- Given the information in the stem, is the item key the correct answer in all situations?
- Is enough information provided in the item for candidates to choose an answer?
- Given the information in the stem, are the distractors incorrect in all situations?
- Would a participant with specialized knowledge interpret the item and the options differently from the general population of participants?
- Is the item tagged to the correct area of the specifications (e.g., topic, subdomain)?
- Does the item function at the intended cognitive level?
Other content review goals may be added depending on your specific testing purpose. For example, in their chapter in Educational Measurement (4th ed.), Brian Clauser, Melissa Margolis, and Susan Case observe that for certification and licensure exams, a content review committee might determine whether items are relevant to new practitioners—the intended audience for such assessments.
Shmeiser and Welch also recommend that the review process be systematic, implying that the committee should apply a consistent level of scrutiny and decision criteria for each item they review. But how can you as the test developer keep things systematic?
One way is to use a checklist of the acceptance criteria for each item. By using a checklist, you can ensure that the committee reviews and signs off on each aspect of the item’s content. The checklist can also provide a standardized format for documenting problems that need to be addressed by the item writers. These checklists can be used to report the results of the content review, and they can be kept as supporting documentation for the Test Development and Revision requirements specified by the Standards for Educational and Psychological Testing.
In my next post, I’ll suggest some ways for you, as a test developer, to leverage your content review committee to gather content validity evidence for your assessment.
