Following each job practice analysis, the ABO and Authentic Testing collaborate to determine a cut score through a process approved by the National Commission for Certifying Agencies (NCCA).
- Following a new job practice analysis, the ABO Board selects a panel of at least five Subject Matter Experts (SMEs) for participation in a standard setting study. Demographics, experience in optometry and other defining characteristics are taken into consideration during this selection process.
- With the aid of Authentic Testing, and using an NCCA-approved psychometric method, the panel begins to determine cut scores. The SMEs determine the standard of minimal competence for Board Certification through discussion of the minimum level of knowledge a candidate should have in categories of basic knowledge, fundamental understanding, working knowledge and more. The SMEs then rate the items, resulting in a recommended cut score.
- The ABO Board convenes a final standard setting meeting to review the panel recommended cut scores, as well as other statistically valid cut scores, and makes the final decision in accordance with Authentic Testing.
- Authentic Testing conducts an equating process for each board certification exam utilizing past exams.
- Authentic Testing develops a cut score report, reliability report, equating report and standard setting report for the ABO to keep in its records.
