This report addresses the success of students as they progress through reading, English, and mathematics course sequences at Miami-Dade Community College (M-DCC) (Florida). Results suggest that passing prerequisite courses does not ensure that students are adequately prepared for the next course in the sequence, especially in the lower-level college preparatory courses, or when earning 'C' grades in college-level courses. Pass rates in reading courses ranging from 58% to 64%, for students who successfully completed the prerequisite course the previous term, suggest that students were reasonably well prepared. However, mathematics course pass rates indicate that students were not prepared by simply passing the prerequisite course. For college-level English and mathematics courses, students who earned higher grades in the prerequisite courses were better prepared for the next course than students who passed with 'C' grades. Results also varied by course within subject areas, with some courses in a sequence appearing to be more difficult for students than others, even after successfully completing the prescribed prerequisite course. In most cases, students placed directly into courses by test scores were more successful than students who progressed through college preparatory or prerequisite courses. (JA)
