Methods: Physical education teachers (N = 327; 56.6% females) from 235 secondary schools (33.1% of national total) in the Republic of Ireland completed a survey designed specifically for the purposes of this study. Results: HRPF tests were used by 95.3% of teachers. A significant decline in the testing frequency was observed from the junior grades (age 13-15 years) to the senior grades (age 16-18 years) (p < .001). Just over half (51.7%) of the teachers discarded the test results after a single use. Less than one third of the teachers indicated that they shared the test results with the students' parents. The vast majority (87.0%) of the teachers agreed that the development of a digital platform would facilitate monitoring test results over time. Conclusions: HRPF testing is highly prevalent in secondary schools. More actions are needed to ensure that teachers use pedagogically sound student-centered approaches toward monitoring HRPF, with a focus on learning that may lead to more positive testing experiences for students. Consideration should be given to the development of digital platforms to facilitate monitoring and reporting HRPF.
