Police officer physical ability testing – Re‐validating a selection criterion
Bibliographic record
Abstract
The aim of this study was to determine the bona fide occupational requirements of general duty police work, and use this information to re‐validate a physical abilities test used in the police recruit selection process. A systematic random sample ( n = 267) of general duty police officers completed two questionnaires: one concerning “average” duties, and one concerning the most physically demanding critical incident occurring in the 12 months prior. Of those completing the surveys, observational data were collected on every second officer, resulting in observational data collected for 121 officers, involving the recording of all physical activities and movement patterns observed throughout a ten hour shift. Data collected suggest there is a core of bona fide occupational requirements for general duty police work – walking, climbing stairs, manipulating objects, twisting/turning, pulling/pushing, running, bending, squatting and kneeling, and lifting and carrying. Many of these are involved in physical control of suspects, and can be tested using a well designed physical abilities test that simulates getting to the problem, controlling the problem, and removing the problem.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
