It has become an apparent confusion in the minds of many people regarding the meaning of the terms “test, measurement, and evaluation”.

Thus, when an achievement test is administered, teachers might say they are testing achievement or measuring achievement or evaluating achievement.

Whereas these terms are certainly related, they are not synonymous. Tests have the narrowest meaning of the three terms.

Test

A test is an instrument or systematic procedure for measuring a sample of behavior. It involves the presentation of a standard of questions to a person or a group of persons to be answered.

Arising from the answers given or supplied, a measure is obtained, and this measure, usually called a score, is quantitative or numerical.

However, testing is just a type of measurement. We can measure characteristics in ways other than by testing. These other ways include using observations, rating scales, and inventories.

So, measurement is a broader term than a  test. Its outcome is always expressed in numbers or quantitatively.

Measurement

Measurement is a process. The process of administering and scoring tests, for example, is measurement.

It tends to answer the question “How much?” Its outcome might be, for example, that Tolu correctly solved seven out of ten statistics problems.

But EVALUATION is broader in its meaning. Evaluation involves both measurement (quantitative descriptions) and non-measurement (qualitative descriptions). It includes value judgment on the worth of the description obtained.

The interpretation of scores is a part of the evaluation. In our example on Tolu, questions such as is his work neat? Is it legible? Is she making progress?

In statistics, how well does he compare with his colleagues in statistics? Is the score 7 out of 10? All these questions are relevant to the evaluation.

Evaluation

Then, evaluation may be defined as a process that allows one to make a value judgment about a measure or the process of providing useful information for judging decision alternatives.

It has been defined by Grounlund (1985) as the systematic process of collection, analyzing, and interpreting information to determine the extent to which pupils are achieving instructional objectives.

Purpose of test

The purpose of tests largely determines both the types of test that is desirable and the properties or characteristics of the test that will be appropriate. The following are how tests are important:

Clarification of course objectives

Every course of study has stated objectives to achieve at the end of the lesson. The objectives are measures of the lesson’s success.

If these objectives are achieved at the end of the lesson, the lesson is successful, but if the objectives are not well achieved, the teacher has to re-explain the concept of the lesson in line with the stated objectives to ascertain the understanding of the lesson.

Therefore, the test provides stimulates a teacher to clarify and refines course objectives.

Test serves as a means of feedback

The test provides a means of feedback to the counselor.

Similarly, scores obtained from vocational interest, inventories, and aptitude tests help the counselor to place an individual counselee into a vocation or career environment within which he can perform maximally and remain the person he is.

The test can increase the quality of selection decisions. We may note that the selection decision is concerned with whether a person should be admitted, employed, rejected, etc.
