Educational testing refers to the process of assessing a student's knowledge, skills, and abilities in a specific subject or area. These tests can take various forms, including multiple-choice questions, essays, and practical assessments. The results help educators understand a student's progress and identify areas that may need improvement. Standardized tests, such as the SAT or ACT, are commonly used for college admissions in the United States. They provide a uniform measure to compare students from different schools. Additionally, formative assessments, like quizzes and classwork, help teachers adjust their instruction to better meet the needs of their students.
