We derived an index of high school academic rigor (HSAR) by optimizing the prediction of first-year college GPA (FYGPA) based on high school courses taken, grades, and indicators of advanced coursework. Using a large data set and nominal parameterization of high school course outcomes, the HSAR index capitalizes on differential contributions…

We examined summary indices of high school performance (coursework, grades, and test scores) based on the graded response model (GRM). The indices varied by inclusion of ACT test scores and whether high school courses were constrained to have the same difficulty and discrimination across groups of schools.

Many academically-advanced youth take the ACT® test in 7th grade for academic talent searches and again in 11th or 12th grade for college admissions. We leveraged this sample of 460,033 students, taking an exploratory analytic approach to examine trends in academic growth from 1996 to 2016. We examined potential predictors of academic growth,…

Predictors included sociodemographics, interests, high school (HS) characteristics, HS coursework and GPA, and extracurriculars, which explained 25% of the…
