The report presents data on the rate of Oklahoma high school graduates going on to colleges within the state. Two kinds of rates are reported: (1) for students proceeding directly to college after high school graduation (linear), and (2) for students who have delayed college entry for a year or more after graduation. Tables present data on: percentage rates for these groups, by county, for each of the years 1994, 1995, and 1996, and as a three-year average; three-year average rates (numbers and percentages) of college attendance for both groups (linear and combined) for each county and each high school; and annual rates for both groups for each county and high school.
