This qualitative phenomenological inquiry aimed to explore the experiential dimensions of first-year, first-semester college students' perceptions of their college readiness from high school to a junior college in Belize. Employing Leedy and Ormrod's (2016) methodology for data analysis, the researcher engaged a purposeful sample of 30 first-year, first-semester college students through in-person interviews using semi-structured interview protocols. The study was guided by the sociocultural theory. The analysis revealed six prominent themes: (a) Academic Rigor, (b) Belonging, (c) Preparedness, (d) Social Support Networks, (e) Educational Infrastructure and Assistance, and (f) Academic Guidance and Empathy. The identified themes contribute to a comprehensive understanding of the sociocultural and environmental challenges faced by first-year, first-semester students. The study found first-year students were not fully college-ready and required more academic, social, and emotional support for a successful transition. Adapting to collegiate-level coursework, developing effective time management and study skills, navigating social environments and networks, and coping with emotional transitions were common challenges for the students. The main conclusions were transitioning from high school to college poses significant challenges for first-year, first-semester students, including academic, social, emotional, and cultural adjustments. Sociocultural factors, particularly familial background, peer influence, and institutional support, significantly impact students' readiness for college and their overall academic outcomes. Several key recommendations were proposed, including networking of high school and junior college, implementation of a comprehensive orientation programs covering academic expectations, study skills, and social integration; creating inclusive spaces; offering culturally sensitive counseling services; and establishing mentorship programs.
