Classroom assessment refers to the methods educators use to evaluate students' academic readiness, learning, and needs. The purpose of assessment is to gather information about student performance to improve the learning process. Teachers use assessment data to reflect on each student's achievement level and tailor their teaching plans accordingly. There are different types of assessments, including formative assessments done during instruction, diagnostic assessments to identify gaps or misconceptions, placement assessments to determine course levels, and summative assessments after learning is complete to evaluate the overall teaching and learning process.
