The National Center on Accessible Instructional Materials states that curriculum evaluation is a set of measurement procedures that use direct observation and a recording of a student's performance in a specific curriculum to gather information. The information is then used to make instructional decisions.
Curriculum-based assessment is used to help determine what teachers teach based on student performance. It is designed to eliminate unnecessary instructional materials that do not match up with the skills of students and the demands of the current curriculum. For assessments, learning objectives are identified and a specific performance level is established for math, reading, science, dictionary skills, direction following and the use of study skills. The measurement procedures and the data collected vary for each area of study.
