This legislative proposal directs the Secretary of Defense, in coordination with relevant Secretaries, to update Department of Defense guidance for the Junior Reserve Officers' Training Corps (JROTC) program within 270 days of enactment. The updated guidance must incorporate an evaluation plan to assess the impact of the JROTC Standardized Instructor Pay Scale (JSIPS) on instructor recruitment and retention. It also requires the establishment of standardized metrics for measuring recruiting outcomes and retention rates across all military services. The evaluation plan mandates specific metrics, including instructor vacancy rates, time-to-hire, retention rates, and geographic variations in outcomes. It also requires comparisons between the legacy pay system and JSIPS, analysis of recruiting efforts, and data on applicant progression and offer acceptance or decline. Following the issuance of updated guidance, the Secretary must submit an initial report to Congress within one year, and then annually for two subsequent years, detailing the implementation, collected data, assessment of pay scale effects, and any recommendations for legislative or administrative actions.
