Under Continuous and Comprehensive Evaluation (CCE), upon deep analysis of the philosophical and pedagogical nature of 'Diagnostic Assessment', 'Formative Assessment', and 'Summative Assessment', which of the following statements most accurately defines the interrelationships and purposes of these three assessments?

In Continuous and Comprehensive Evaluation (CCE), different forms of assessment play distinct roles. The primary objective of Diagnostic Assessment is to identify the root causes of specific learning difficulties, weaknesses, and errors among students.

Formative Assessment runs continuously during the teaching-learning process to monitor student progress and make necessary pedagogical improvements. Conversely, Summative Assessment is conducted at the end of a specific instructional period (such as a term or half-year) to evaluate and certify the overall achievement of students.
