As part of a larger study to provide "indicators" of high school educational performance, this report presents data on remedial services provided to 15,042 college freshmen (1996-97) in Oklahoma public colleges by Oklahoma high school for the graduating class of 1995-96. The study used a student-cohort flow system to track student data semester-by-semester, including courses taken and whether a course was remedial or not. A table summarizes remediation rates by county for science, English, math, and reading. The bulk of the report is in the form of a table for each high school, grouped by county, followed by the college freshman headcount, percentage of freshmen taking remedial courses in the four subject areas, and an unduplicated headcount and percentage of students taking remedial courses. The data show that 37.3 percent of freshmen took at least one remedial course. Mathematics remediation was the highest, with 33.1 percent of freshmen taking a remedial mathematics course. (DB)
