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

Core Content

The 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 duties in specialties with physical demands. The SAT, developed in the early 1980s, has not been revalidated since its inception. The report aims to determine if the SAT and related tests are still valid indicators of physical readiness for these roles and to suggest alternative strategies for improving the accuracy of these assessments while minimizing adverse effects on women's job opportunities.

Main Points

• SAT Overview: The SAT is a weight-lifting test using an incremental lifting machine, where recruits lift increasing weights until failure or meeting the specialty-specific requirement. It has been used for decades to assess physical strength.
• Changing Needs: The composition of the Air Force and the duties of its specialties have evolved over time, necessitating a reevaluation of the SAT’s relevance and effectiveness.
• Research Objectives: The study aims to determine the predictive validity of the SAT and related fitness tests, assess the physical demands of different Air Force Specialty Codes (AFSCs), and explore alternative test batteries that could enhance the accuracy of physical capability assessments.
• Validation Approach: RAND, in collaboration with HumRRO, conducted a series of studies including job analyses, task simulations, and statistical evaluations to assess the relationship between SAT scores, performance, and injury rates.
• Findings: The SAT is found to be a valid measure of physical capability, but its predictive validity is limited. Adding the Arm Endurance Test significantly improves validity, as it measures upper body muscular endurance and anaerobic power, which are important for physically demanding tasks.
• Courses of Action (COAs): Four COAs are proposed, each with different combinations of tests and cost implications, aiming to balance validity, cost, and fairness.

Key Information

Physical Requirements by AFSC

• SAT Score Distribution: 38% of AFSCs require a 40-pound SAT score, and 26% require a 70-pound score.
• Current Performance: Most men lift 60 pounds or more, and about 87% of women also do so. The SAT becomes more discriminatory for women at the 70-pound level.
• Task Analysis: Through interviews with Career Field Managers (CFMs) and subject-matter experts, the physical tasks required by AFSCs were identified, including lifting, climbing, pushing, and pulling.

Validation Studies

• Predictive Validity: The SAT and related tests were evaluated for their ability to predict performance on physical tasks. The Arm Endurance Test showed the most significant improvement in validity when combined with the SAT.
• Injury Analysis: The relationship between SAT scores and injuries was examined, but the data were limited and not conclusive due to underreporting and the nature of the dataset.

Test Battery Options

The following five test battery options were evaluated:

1. Option 1: SAT only (baseline)
2. Option 2: SAT plus any single test
3. Option 3: SAT plus as many other tests as needed
4. Option 4: SAT plus any single inexpensive test
5. Option 5: SAT plus all inexpensive tests

Recommended COAs

The report outlines four COAs:

• COA #1: SAT, Arm Endurance, Push-Ups, and Handgrip (maximizes validity)
• COA #2: SAT and Standing Broad Jump (maximizes validity without additional equipment costs)
• COA #3: SAT and Arm Endurance (maximizes validity with limited additional costs)
• COA #4: SAT only (retains current standards)

Each COA has its own advantages and disadvantages, as detailed in the report.

Implementation Plan

To ensure the validity and effectiveness of any chosen COA, the report recommends the following steps:

1. Integrate Physical Demand Survey Items: Into the Occupational Analysis Division’s routine surveys for each AFSC.
2. Provide Summary Job Analysis Data: To CFMs and senior leaders.
3. Collect Feedback: From CFMs and senior leaders on survey results.
4. Administer New Tests: At MEPS to gather data on new recruits.
5. Collect Physical Performance Data: For recruits assigned to each AFSC.
6. Verify SAT Requirements: Using test and performance data.
7. Calibrate and Adjust Requirements: Based on feedback and data.
8. Establish Regular Monitoring and Updating: Of test requirements to keep pace with changes in job demands.

Key Considerations

• Gender Bias: The SAT may have a potential gender bias, especially at higher score levels, which could affect job opportunities for women. Alternative tests, such as the Arm Endurance Test, were found to reduce this bias.
• Data Limitations: Existing data on SAT scores and injuries are limited, making it difficult to fully assess the test’s validity. Additional data collection is necessary for more accurate evaluation.
• Efficiency and Fidelity: Focusing physical testing resources on the most demanding AFSCs can improve the efficiency and fidelity of the overall process.

Conclusion

The report concludes that while the SAT remains a valid measure, combining it with other tests can enhance its predictive validity. The Air Force should consider adopting a more comprehensive approach to physical testing, while also maintaining current standards until further data can be collected. The implementation plan emphasizes the need for ongoing monitoring and updating of test requirements to ensure they remain aligned with the evolving demands of Air Force jobs.
