Standardized testing refers to a type of assessment that is administered and scored in a consistent manner across all test-takers. These tests are designed to measure students' knowledge and skills in specific subjects, such as math and reading, and are often used to evaluate educational performance at various levels, including elementary, middle, and high school. These tests are typically created by educational organizations or government agencies and are used to compare the performance of students, schools, or districts. Examples of standardized tests include the SAT, ACT, and PARCC. The results can influence educational policy, funding, and student placement in advanced programs.
