The purpose of this study was to determine if there has been a change to the scores on the Texas State Peace Officer Licensing Examination over a given time, and if been a so, identify subjects where scores improved or declined. By recognizing stagnation or declination in test scores, interventions can be designed to enhance the adult learning experience for peace officer candidates. To determine if a change over time occurred, I utilized a non-experimental, longitudinal, descriptive quantitative analysis research design. My results showed that there was a change in 8 of 23 topics investigated. 7 topics showed a decline in pass rate over the study period and 1 topic showed an increase in pass rate over the study period. The study suggests that topics showing a decline in test scores for academy students correspond with changes in delivery methods brought about by staff changes and the global pandemic. It further suggests that increases in test scores for academy students correspond with increases in curricular hours and added topic emphasis.
