This report presents data analyses investigating the relationship of high school final average, X, and first year university average, Y, in a Canadian university. The statistical summaries are (1) a matrix of observed "relative grading standards" of each high school in each matriculation year, and (2) a quadratic regression relating Y to X in each year. These summaries suggest that (l) the grading standards for some of the schools are changing consistently in time, and (2) the general relationship between Y and X is becoming more quadratic and less linear in time. The implication is that the high school attended is a more important predictor of university performance for students with poorer high school records than for students with better high school records, especially in recent years.
