This study investigates the level of skill acquisition among senior high school student-athletes in Region XI, Philippines, employing the Fitts and Posner Three-Stage Model to categorize their progress into cognitive, associative, and autonomous phases. Utilizing a descriptive-comparative research design and a structured questionnaire, data were collected from 53 respondents aged 16 to 18 years, enrolled in Grades 11 and 12. The findings reveal that, overall, student-athletes exhibit a high level of skill acquisition, with significant differences observed across gender and year level categories. The study highlights the critical influence of demographic factors on athletic development and underscores the importance of tailored interventions. This study is anchored on the theory of The Fitts and Posner Three-Stage Model by Paul Fitts and Michael Posner in 1967. Based on the results, a program titled “STEP-UP: Skill Training and Enhancement Program for Upgrading Performance” is proposed to address perceived gaps and foster effective skill progression among student-athletes. These insights aim to inform coaches, educators, and stakeholders in fostering an environment conducive to athletic and personal growth among youth.
