The task inventory approach is commonly used in job analysis for establishing content validity evidence supporting the use and interpretation of licensure and certification examinations. Although the results of a task inventory survey provide job task‐related information that can be used as a reliable and valid source for test development, it is often the knowledge, skills, and abilities (KSAs) required for performing the tasks, rather than the job tasks themselves, which are tested by licensure and certification exams. This article presents a framework that addresses the important role of KSAs in developing and validating licensure and certification examinations. This includes the use of KSAs in linking job task survey results to the test content outline, transferring job task weights to test specifications, and eventually applying the results to the development of the test items. The impact of using KSAs in the development of test specifications is illustrated from job analyses for two diverse professions. One method for transferring job task weights from the job analysis to test specifications through KSAs is also presented, along with examples. The two examples demonstrated in this article are taken from nursing certification and real estate licensure programs. However, the methodology for using KSAs to link job tasks and test content is also applicable in the development of teacher credentialing examinations.
