Objective tests

Are questions that demand answers that are either right or wrong and for each of which there is only one possible correct answer.

Advantages
Are easy to mark and grade.
Examine a wide coverage of the topics learned hence students read widely.
They are practical and handy for relatively large classes.
Human error, bias or prejudice by the marker is removed i.e. scoring is extremely reliable.
If well set, they have a strong discriminative power between the bright and weak students.
Learners obtain feedback on their performance much faster.

Disadvantages
Are difficult to set and therefore time consuming.
They are open to guesswork.
They limit the learners use of his/her acquired writing and literary skills e.g. creativity, analysis or evaluation.
They are relatively expensive in terms of materials needed to produce a complete test.
The selection of questions may greatly be influenced by the examiners bias
