Educational measurement refers to the process of assessing students' knowledge, skills, and abilities through various tools and methods. This can include tests, quizzes, and assignments that help educators understand how well students are learning. By measuring educational outcomes, teachers can identify areas where students may need additional support or enrichment. The results from educational measurement can inform instructional practices and curriculum development. For example, standardized tests like the SAT or ACT provide data that can guide schools in improving their programs. Ultimately, effective educational measurement helps ensure that all students receive a quality education tailored to their needs.
