High school grades are a better predictor of college success than standardized tests. https://journals.sagepub.com/doi/10.3102/0013189X20902110 https://journals.sagepub.com/doi/10.3102/0013189X20902110 > High school GPAs (HSGPAs) are often perceived to represent inconsistent levels of readiness for college across high schools, whereas test scores (e.g., ACT scores) are seen as comparable. This study tests those assumptions, examining variation across high schools of both HSGPAs and ACT scores as measures of academic readiness for college. We found students with the same HSGPA or the same ACT score graduate at very different rates based on which high school they attended. Yet, the relationship of HSGPAs with college graduation is strong and consistent and larger than school effects. In contrast, the relationship of ACT scores with college graduation is weak and smaller than high school effects, and the slope of the relationship varies by high school. https://journals.sagepub.com/doi/full/10.3102/0002831219843292 https://journals.sagepub.com/doi/full/10.3102/00028312198432... > Since World War II, high school report card grades and standardized college entrance exams—most prominently the SAT and ACT—have been the two gatekeepers of university admissions ... It is surprising, perhaps, that high school grades are a stronger incremental predictor of college outcomes—including what is arguably the most important outcome of all: graduation.
