Standardized tests are assessments designed to measure students' academic performance in a consistent manner. These tests are administered and scored in a uniform way, allowing for comparisons across different individuals or groups. Common examples include the SAT, ACT, and GRE, which are often used for college admissions in the United States. The primary purpose of standardized tests is to evaluate knowledge and skills in specific subjects, such as math and reading. They aim to provide an objective measure of student achievement, helping educators and policymakers make informed decisions about education systems and student progress.
