Difference Between Prognostic and Diagnostic Evaluation in Education with Examples

According to Mary Thorpe,

“Evaluation is the collection, analysis and interpretation of information about any aspect of a programme of education, as part of a recognised process of judging its effectiveness, its efficiency and any other outcomes it may have.”

Assessment refers to the process of collecting information that reflects the performance of a student, school, classroom, or an academic system based on a set of standards, learning criteria, or curricula.

Beeby opines,

“Evaluation is the systematic collection and inter- pretation of evidence leading as a part of process to a judgement of value with a view to action.”

Diagnostic evaluation is a type of pre-assessment which allows teachers to assess the strengths, weaknesses, knowledge, and skills of the learners before starting the teaching learning process. Prognostic evaluation refers to the assessment that includes the prediction of a learner’s future career through the means of estimation.

Fenton (1996) states,

“Evaluation is the application of a standard and a decision-making system to assessment data to produce judgments about the amount and adequacy of the learning that has taken place.”

Evaluation is a process which is continuous as well as comprehensive and involves all the tasks of education and not merely tests, measurements, and examination.
