Summary of the Evaluation of the Strength Aptitude Test and Other Fitness Tests for Air Force Recruit Qualification

Core Content

This report evaluates the Strength Aptitude Test (SAT) and other fitness tests used by the U.S. Air Force to determine if recruits are physically capable of performing the duties of various Air Force Specialty Codes (AFSCs). The SAT, developed in the early 1980s, is a weight-lifting test that assesses a recruit's ability to lift increasing weights on an incremental lifting machine. However, due to changes in the Air Force's composition and job requirements, the SAT's validity and effectiveness have come into question.

The report outlines a series of studies conducted between 2010 and 2015, including a survey of Career Field Managers (CFMs), analysis of SAT and Enlisted Performance Ratings (EPR) data, and task simulations to assess physical performance. The goal is to ensure that the physical fitness tests used to qualify recruits for physically demanding AFSCs are both valid and equitable, especially considering the inclusion of women in all roles.

Main Points and Findings

• SAT Overview: The SAT is a weight-lifting test used to determine if recruits meet the physical requirements for their assigned AFSCs. It has not been revalidated since its introduction in the 1980s.
• Changes in the Air Force: Over time, the duties and physical demands of many AFSCs have evolved, necessitating a reevaluation of the SAT's relevance and effectiveness.
• Manager Perspectives: A survey of CFMs found that most were satisfied with current SAT requirements. However, there were more drawbacks than benefits to removing the SAT.
• Predictive Validity: Initial analyses of SAT and EPR data showed that available measures were insufficient to evaluate the SAT's predictive validity for performance or injury risk. The SAT scores tend to cluster at the high end, making it difficult to identify meaningful relationships.
• Task Simulations: RAND and HumRRO developed task simulations to better understand the physical demands of various AFSCs. These simulations included lifting and carrying, lifting and holding, climbing, and pushing and pulling.
• Fitness Tests Evaluated: Several other fitness tests were evaluated alongside the SAT, including Arm Endurance, Arm Lift, Handgrip, Plank Test, Push-Ups, Sit-Ups, Standing Broad Jump, and Step Test.
• Validation Study: The study found that adding the Arm Endurance test to the SAT significantly increased validity. This test measures upper body muscular endurance and anaerobic power.
• Courses of Action (COAs): Four COAs were analyzed, each with different combinations of tests and cost implications. The best option in terms of validity was to combine SAT with Arm Endurance, Push-Ups, and Handgrip, although this requires additional resources. Other options included using no-cost tests or retaining the SAT alone.
• Recommendations: The report recommends maintaining current SAT standards while implementing a phased approach to test new options. It emphasizes the need for ongoing data collection, calibration, and regular monitoring of physical requirements to ensure they remain valid and equitable.

Key Information

• SAT Requirements: 38% of AFSCs require a 40-pound SAT score, and 26% require 70 pounds.
• Physical Training Impact: Data suggests that physical training during Basic Military Training (BMT) can improve recruits' strength, indicating the need for updated testing standards.
• Gender Bias Concerns: The SAT may have potential gender bias, with some tests overpredicting female performance and underpredicting male performance.
• Implementation Plan: The report outlines an implementation plan that includes integrating job analysis survey items, collecting feedback from CFMs, administering new tests at MEPS, and calibrating standards based on data and feedback.

Conclusion

The report concludes that while the SAT remains a valid measure of physical capability, augmenting it with additional tests can enhance its predictive validity. It also emphasizes the importance of maintaining current standards until more comprehensive data can be collected and recommends a systematic approach to updating physical requirements in line with evolving job demands and ensuring fairness across all recruits.
