Explanation:

The history of tests, as cited by Saiyadain, can be traced back to the efforts of Francies Galton who developed a variety of tests of sensory determination to measure person’s intellect as far back as 1883. Since then, there is no looking back with regard to the use of selection tests. As a result, a large number of general aptitude tests and specific skill tests for the purpose of selecting employees are available today.

All the tests so far developed for the selection of employees can broadly be divided into two categories:

(i) Ability Tests and

(ii) Personality Tests.
