Development and validation of an assessment tool for a national young worker curriculum

BackgroundAn online, multiple-choice assessment was developed and validated for Youth@Work-Talking Safety, a NIOSH curriculum that equips middle and high school students with foundational workplace safety and health knowledge and skills. MethodsClassical Test Theory was used for the test development and validation; the Jaeger method was used for cut score determination. A total of 118 multiple-choice items were developed to measure the acquisition of knowledge and skills taught through the NIOSH curriculum. Pilot testing was conducted with 192 8-12th grade students and a cut score was determined. ResultsThe mean score for all test-takers on the Talking Safety assessment was 80.9%; total test reliability measured using an Alpha/KR20 statistic was 0.93. A minimum passing (cut) score of 74% was established. ConclusionsThe assessment provides an objective measure of students' acquisition of the foundational workplace safety and health competencies taught through the Talking Safety curriculum. Am. J. Ind.
