other learners and judge whether it is good/bad/average or

satisfactory/unsatisfactory, we are doing an act of evaluation

Measurement is a part of process of Evaluation

Measurement is that part of Evaluation which is expressed in percentage,

quantity, digits, mean and average.

Evaluation depends upon measurement but it is not synonymous to it.

Evaluation encompasses but goes beyond the meaning of the terms “test” and “measurement”
