Understanding learning progress of students
The main purpose of assessment should be to understand the learning progress of students. It is a tool to evaluate how well students are learning, what they understand, and where they may need additional support. Assessment is not meant for labeling students, creating ability-based groupings, or detaining students who score low. Instead, it provides valuable feedback to both teachers and students about the effectiveness of instruction and learning, guiding improvements in teaching strategies and student learning processes.
