How well does high school grade point average predict college performance by student urbanicity and timing of college entry?

This report is a companion to a study that found that high school grade point average was a stronger predictor of performance in college-level English and math than were standardized exam scores among first-time students at the University of Alaska who enrolled directly in college-level courses. This report examines how well high school grade point average and standardized exam scores predict college grades by the urbanicity of students' hometown and timing of college entry. Among recent high school graduates from both urban and rural areas of Alaska, high school grade point average was a better predictor of college course grades than were SAT, ACT, or ACCUPLACER scores. It was a more powerful predictor of college performance among students who entered college within a year of high school graduation than among students who delayed college entry. For students who delayed college entry, high school grade point average was a better predictor than were standardized exam scores in English, but that was not always the case in math.
