The purpose of this study was to investigate the challenges faced by first-year students as they negotiated the transition from the writing environment of high school to the writing environment of university. The research for the dissertation was undertaken using a mixed-method explanatory design. This yielded a description of students' perceptions of the differences between their high school writing and first-year university writing environments. The research questions were as follows: what are high school students' perceptions of their writing environment; and what differences, if any, do students perceive as different in the writing environment between high school and first-year university? A total of one hundred and forty-four Grade 12 students completed a quantitative survey asking for their perceptions of the high school writing environment, and twenty students took part either in qualitative focus groups or individual interviews. A follow-up interview was conducted with fourteen of the original twenty participants while they were in the process of completing their first term at university. The results indicated that students' perceptions were very much influenced by individual teachers and instructors and by their own expectations. Recommendations, implications for further research, and implications for program development are offered as a way to extend the knowledge in this area. The following are appended: (1) Quantitative Survey for High School Students; (2) Interview/Focus Group Protocol; and (3) Ethics Approval Certificate.
