Reforms in K-12 science education are global. New national science curricula were introduced in the United States (NRC, 1996), in Canada (CEMC, 1997), and in Europe (European Commission 2007). In this article, the impact of these reforms on college students in Quebec is studied. Articulation between high school and college sectors is viewed through the lens of STEM (Science, Technology, Engineering, Math) high school and college faculty. Faculty of both communities experienced stress as the first education reform curricula cohorts entered college. Results of a diagnostic test developed by CEGEP faculty to assess college preparedness found no difference in math and science content knowledge when pre-reform cohorts were compared with cohorts instructed with the reform curriculum. Improvements were observed in problem solving skills, which has led to changes in pedagogy at the college level. Articulation between the two sectors could alleviate anxieties among faculty and students.
