Report cards have been a staple of the education system for over 100 years. Grades are employed as a high stakes method to determine advancement from one grade to the next and, along with standardized tests (e.g. SAT and ACT), the traditional basis for determining admissions into college. Aggregated grades are also commonly used as a way to measure the overall success of school systems. Despite the widespread use of grades, issues regarding the reliability and validity of grades exist. Concerns pertaining to differing standards used for assigning grades along with grading inflation bring into question the validity of grades as a high-stakes tool in education. Standardized tests are purported by the College Board and testing companies to be more rigorous, providing a more consistent and accurate measure of student skill acquisition and achievement. While improvements in how grades are assigned can and should be pursued, research finds high-school grade point average to be a consistent and reliable predictor of grades in the college freshman year, dropping out of college, and overall college performance.
