The purpose of this study was to investigate links among experiences commonly associated with strategies and experiences of surface versus deep learning in science, technology, engineering, and mathematics (STEM) courses, STEM school graduates' (n = 3,526) reported level of college readiness, and eventual completion of university degrees in a STEM discipline. Using logistic regression analysis, we identified 4 variables linked to reported feelings of college readiness of graduates of specialized STEM high schools and their reported undergraduate degrees. These variables comprised: (a) the level of focus on deep conceptual understanding in STEM content, (b) the number of concepts covered in high school STEM classes, (c) the depth of concept coverage, and (d) connections made between STEM concepts and other content areas. Of these 4 variables, some were found to be positively associated with graduates' feelings of college readiness; yet, no variables were associated with earning an undergraduate degree in STEM.
