For decades, standardized tests like the SAT and ACT have been a major part of the high school experience for students planning to attend college. However, many students are still unsure how important these tests actually are, especially when it comes to graduating from high school and applying to colleges.
The SAT, which stands for Scholastic Assessment Test, and the ACT, short for American College Test, are designed to measure a student’s readiness for college-level work. Both exams test skills such as reading comprehension, writing, and mathematics. According to the College Board and ACT, Inc., the organization that administers the SAT, about 2 million students in the United States took the SAT in 2025 and roughly 1.38 million students took the ACT during the same year.
Despite their popularity, neither the SAT nor the ACT is usually required for students to graduate from high school. Graduation requirements are set by individual states and school districts. Most schools require students to complete a certain number of credits in subjects such as English, math, science, and social studies in order to receive a diploma. States by the U.S. Department of Education, standardized college entrance exams like the SAT and ACT are primarily intended for college admissions rather than high school graduation requirements.
However, these tests can still play a role in the college admissions process. Many colleges consider standardized test scores alongside other factors such as high school grades, course difficulty, extracurricular activities, essays, and recommendation letters, reported by the National Center for Education Statistics. While test scores can strengthen an application, they are typically only one part of a much larger evaluation.
In recent years, the role of standardized testing has changed significantly. Based on education data reported by Higher Ed Dive, more than 2,000 colleges and universities in the United States have adopted test-optional policies, meaning students are not required to submit SAT or ACT scores when applying. This trend began during the COVID-19 pandemic when many testing centers closed and has continued as schools reassess how much weight standardized tests should carry.
Even so, some colleges still value these exams. According to several university admissions offices, standardized tests can help schools compare students from different high schools and grading systems. Because of this, some highly selective universities have begun reintroducing testing requirements for certain future admissions cycles.
When comparing the two tests, colleges generally do not prefer one over the other. Stated by the College Board and ACT, Inc., admissions offices use score conversion charts to compare results from the SAT and ACT fairly. This means students can choose whichever exam best fits their strengths.
Education researchers also emphasize that grades often matter more than test scores; high school GPA is often a stronger predictor of college success than standardized test scores. Students who maintain strong grades throughout high school are more likely to graduate from college than students who rely on test scores alone.
For high school students trying to decide where to focus their efforts, the message from educators is fairly clear. Completing coursework and maintaining strong grades should remain the top priority for graduating high school. At the same time, taking the SAT or ACT can still be helpful for students applying to competitive colleges or seeking scholarships.
As standardized testing continues to evolve, one thing remains certain: while the SAT and ACT may influence college opportunities, success in high school still depends most on consistent academic performance in the classroom.
