Classroom assessment encompasses various procedures to evaluate student performance, serving as a continuous process of identifying, gathering, organizing, and interpreting learners' knowledge and skills. It is divided into formative assessment, which aids learning through feedback and instructional adjustments, and summative assessment, which measures knowledge at the end of a learning period. Effective grading and recording of progress are essential, with specific weights assigned to written work, performance tasks, and assessments in the K to 12 curriculum.
