This study examined the relationship and predictive value of scores from the AFOQT Form S with Final School Grade (FSG) for Air Force Officer Cyberspace Operations / Cyberspace Control School (17D Undergraduate Cyber Training Phase II). Form S scores include officer aptitude composites (e.g., Pilot Composite), individual sub-tests (e.g., Word Knowledge), and Domain (e.g., Conscientiousness) and Facet (e.g., Achievement-Striving) personality scales from the Self-Description Inventory Plus (SDI+). Data from all non-prior service U.S. Air Force Officers who attended the school from November 2010 to March 2012 (N=295) were analyzed and results are reported herein. The sample was separated by quintiles on FSG and results are displayed for each predictor by quintile. The number of attrits was calculated for each quintile, showing a total of only 12, of which 10 fell in the bottom two quintiles and none in the top quintile. All composites and sub-tests were significantly correlated to FSG as were many of the domain and facet scales of the SDI+. A model of the best combination of individual predictors was determined through a series of multiple regression analyses. Recommendations for a best-use selection model and cut-scores are made.
