Tests as Selection Tool

[abhishreshthaa]

Test are useful selection devices in that they unover qualifications and talents that can’t be detected otherwise. They can be used to predict how well one would perform if one is hired, why one behaves the way one does, what situational factors influence employee productivity, etc. Tests also provide unbiased information that can be put to scientific and statistical analysis.


However, tests suffer from sizeable errors of estimate. Most psychological tests also have one common weakness, that is, we can’t use scales which have a know zero point and equal intervals. An intelligence test, for example starts at an arbitrary point, where a person may not be able to answer question properly. This does not mean that the person is totally lacking in intelligence.


Likewise, a person who is able to answer all the 10 questions correctly cannot be called twice as intelligent as the one who was able to answer only 5. If the test has commenced at some other point, where there easier questions, their score might have been different.


Test also fails to elicit truthful responses from testees. To compound the problem further, test results are interpreted in a subjective was by testers and unless these testers do their homework well, the results may not be reliable.
