During the fall 1986 administration of the College Level Academic Skills Test (CLAST), 980 Miami-Dade Community College (MDCC) students took the exam for the first time. Of this group, 71.6% passed, and 28.4% failed one or more CLAST subtests. A study was conducted of the group of students who were required to retake one or more subtests in order to pass the exam. The study sought to determine the numbers of students who retook the exam and ultimately passed all four parts, those who retook the exam and still did not pass all four parts, and those who did not retake the exam. Data from the MDCC CLAST research file were supplemented with state CLAST data to identify students who retook the CLAST at other institutions. Study findings, which included comparisons with results from a similar study conducted in 1984, revealed the following: (1) of the 278 students who took the CLAST for the first time in fall 1986 and failed, 67.2% retook the exam at MDCC or another school during the following year and passed, and 16.2% retook it and failed again; (2) considering only MDCC testing data, the number of students who retook the CLAST increased from 66% in 1984 to 77.7% in 1986; and (3) combining the percentages of students who passed the CLAST the first time and those who passed it the second time, the ultimate pass rates were 86% for the 1984 group and 90.8% for the 1986 group.
