The disavantages of group intelligence tests include that.

Answer 1

Advantages of group tests:

can be administered to very large numbers simultaneously

simplified examiner role

scoring typically more objective

large, representative samples often used leading to better established norms

Disadvantages of group tests:

examiner has less opportunity to establish rapport, obtain cooperation, and maintain interest

not readily detected if examinee tired, anxious, unwell

evidence that emotionally disturbed children do better on individual than group tests

examinee�s responses more restricted

normally an individual is tested on all items in a group test and may become boredom over easy items and frustrated or anxious over difficult items

individual tests typically provide for the examiner to choose items based on the test takers prior responses - moving onto quite difficult items or back to easier items. So individual tests offer more flexibility.
