Generalizability of Walk-Through Performance Tests, Job Proficiency Ratings, and Job Knowledge Tests Across Eight Air Force Specialties
Abstract
Generalizability theory was used to assess the psychometric quality of Walk-Through Performance Tests (WTPTs) and Job Proficiency ratings in eight Air Force occupational specialties. In addition, generalizability theory was used to determine whether proficiency ratings and job knowledge test scores were substitutable for the WTPTs. The results showed that both the WTPT scores and ratings within rating sources were generalizable (reliable), but that ratings were not generalizable over rating sources, and neither ratings nor job knowledge test scores ranked incumbents similarly to the WTPT. Keywords: Case studies; Air force personnel; Performance tests; Reliability; Theory.
