A study was conducted at Miami-Dade Community College (Florida) to assess the performance of ESL students on the College Level Academic Skills Test (CLAST) and the relationship of campus location, ESL credits earned, grade point average (GPA), and developmental coursework on CLAST scores. The study focused on all students who took all four sections of the CLAST in fall 1984. Study findings included the following: (1) only about 10% of all fall 1984 test takers had enrolled in ESL courses; (2) on each of the CLAST subtests, students without ESL coursework performed better than those with ESL coursework, with the differences most evident in the essay portion of the test, and least evident in the computation portion; (3) the number of subtests a student passed seemed to bear little relationship to the number of ESL credits the student had taken; (4) students with a GPA in their ESL coursework of 3.0 or higher were more likely to pass three or four of the CLAST subtests than students with lower GPA's; (5) cumulative GPA was a better predictor of CLAST performance in writing and computation than either the number of ESL credits taken or ESL GPA; and (6) almost 75% of the ESL students had some coursework in developmental reading, writing, or computation.
