A Diagnostic Test is a specialized assessment tool that fundamentally differs from achievement tests by focusing on identifying the underlying reasons for a student's struggles, thereby pinpointing specific learning strengths and weaknesses rather than merely measuring what has been learned.
Following the insights gained from such tests, Remedial Instruction is a crucial, targeted teaching approach that directly addresses the specific learning difficulties identified, aiming to help students overcome their learning gaps and reinforce foundational skills.
The Pre-diagnostic Test serves as an initial assessment, specifically designed to evaluate students' existing knowledge and skills before any new topic is taught, enabling educators to tailor their instruction from the outset.
Crucially, the Formative Nature of Diagnostic Tests means they are primarily used to gather information throughout the learning process to guide ongoing instruction and improve student outcomes, rather than for grading, thus supporting continuous adaptation of teaching methods to meet individual student needs.
