Thomas International conducts a GIA test mainly to ascertain a candidate's fluid intelligence, i.e., how quickly they can learn new skills. The pre-test booklet that is attached is normally given to candidates to get a feel of the test before they attempt it online.
If one is interested in getting themselves tested on the GIA, you could contact Thomas Assessments at www.thomasinternational.net. You will be sent a link. Once the test is completed, the report is generated by them. Like other tests, the interpretation of the GIA report also requires in-depth knowledge of the particular system.
Incidentally, Thomas International is conducting a Certification Workshop in Mumbai on 26-27 Sep.
