Self-assessment provides useful information about students' expectations, problems, progress, and feelings about a course. It is a vital part of learning, as it allows students to improve by assessing how well they are meeting objectives. Initial self-assessment helps students recognize their strong and weak areas by having them complete a questionnaire at the start of a course. Teachers should apply self-assessment tools regularly to obtain technically adequate and fair assessment data that can support instructional decisions by diagnosing needs, planning programs, and evaluating methods.
