| Sumario: | Objective: This multi-part study aimed to revise an existing battery of physical aptitude tests for firefighter applicants. Test validity and reliability were evaluated and performance thresholds were determined. Methods: In Part I, 49 structural firefighters rated the similarity between the physical demands of the tests and corresponding work activities. In Part II, 23 participants completed the tests on 3 separate days. In Part III, cut-scores were determined using the Bookmark method by an expert panel of 25 firefighter supervisors. Results: Analysis revealed high levels of validity and reliability. The expert panel provided invaluable direction through a combination of independent and group work, leading to consensus on acceptable completion times. Conclusion: Rigorous processes established scientific credibility for the revised battery of tests. Expert knowledge from firefighter supervisors contributed to determining cut-scores following established scientific methods.
