The United States' high school admission score requirements vary widely among institutions. The most common criteria include high school GPA and standardized test scores such as the SAT or ACT. These scores are crucial for colleges and universities to assess the academic preparedness of applicants. According to the National Center for Education Statistics (NCES), the average high school GPA for admitted students in 2020 was 3.68, while the average SAT score was 1,030 and the average ACT score was 21. However, these averages can vary significantly depending on the institution's selectivity and the specific program of study. For instance, highly competitive institutions like Harvard and Stanford typically require higher GPAs and test scores, often exceeding 4.0 and 1500+ on the SAT or 32+ on the ACT, respectively. These requirements are in place to ensure that students entering these institutions are well-prepared for the rigorous academic environment.
