In the context of achieving educational objectives and the holistic development of the student, providing a nuanced analysis of the ontological, procedural, and functional differences between 'Assessment' and 'Evaluation', which of the following statements is most appropriate and scientifically valid?

Under Continuous and Comprehensive Evaluation (CCE), assessment and evaluation are distinct yet complementary concepts. Assessment is a continuous process focused on improving student deficiencies during the teaching-learning process (Assessment for Learning) and providing feedback. In contrast, evaluation involves making a value judgment or grading the overall achievement of students at a specific point or at the end of a session based on assessment data.
