Various forms of assessments used in education include formative, summative, diagnostic, and performance assessments. Formative assessments are conducted during the learning process to provide real-time feedback, allowing teachers to adjust instruction. Summative assessments, on the other hand, evaluate student learning at the end of an instructional period. Diagnostic assessments help identify students' strengths and weaknesses before instruction begins, while performance assessments focus on real-world tasks to measure applied knowledge and skills. A diverse assessment approach ensures a comprehensive evaluation of student understanding.
