This scoping review synthesizes literature on secondary science teacher preparation programs across five continents, drawing on 22 peer-reviewed studies. It examines program structures, prevailing challenges, and strategies aimed at addressing science teacher shortages, with a particular focus on rural contexts. The countries represented in the review include the United States, Canada, Germany, China, and others from diverse geographic regions. The findings highlight dominant challenges, including shortages of qualified science teachers, technological, pedagogical, and content knowledge (TPACK) gaps, and limited opportunities for interdisciplinary or transdisciplinary training. Shortages are mitigated through lateral/alternative entry pathways and structured programs offering 3--4-year training, combined with clinical experience to enhance TPACK and meet licensure requirements. Some countries train teachers to teach multiple science subjects and provide incentives through scholarships and higher salaries for those who commit to working in rural schools. These findings offer valuable insights for stakeholders, suggesting adaptable strategies to improve the quality and supply of science teachers and strengthen science education.
