4. Diagnostic Evaluation: Diagnostic evaluation is a form of pre-assessment that allows a teacher to determine students' individual strengths, weaknesses, knowledge, and skills prior to instruction. It is primarily used to diagnose student difficulties and to guide lesson and curriculum planning . This type of evaluation is concerned with finding out the reasons for students persistent or recurring learning difficulties that cannot be resolved by standard corrective measures or formative evaluation.

5. Nature of Diagnostic Evaluation It is corrective in nature. It is more comprehensive. It pinpoints the specific type of error each pupil is making and searches for underlying cause of problem. The aim of diagnostic evaluation is to find out the causes of learning problems and plan to take remedial actions . Observational techniques or specially prepared diagnostic techniques can be used to diagnose the problem. It can be done by constant observation of pupils, analysis of performance, achievement test ,analysis of cumulative record and anecdotal records

First, it allows teachers to plan meaningful and efficient instruction. When a teacher knows exactly what students know or don't know about a topic, she can focus lessons on the topics students still need to learn about rather than what they already know. The diagnostic test takes off where formative test leaves off It is a means by which an individual profile is examined and compared under certain norms or criteria. It is more intensive and act as a tool for analysis of learning difficulties. It is more limited to low ability students . It provides information to individualize instruction. It sets a baseline on a topic.
