Thomas GIA Test Scoring

Here is the Thomas GIA scoring method in a nutshell:


Each Section is Scored Separately

While the GIA Test has a final score, it is calculated based on your score in the 5 test sections.


Wrong Answers Reduce Points

The Thomas International GIA test is scored based on both your correct and incorrect answers. Correct answers gain you points, and incorrect answers reduce points.
Each correct answer gains 1 point, and each wrong answer reduces points, depending on the section:

  • Reasoning – 1 point reduced for an incorrect answer
  • Perceptual Speed – 0.25 points reduced
  • Number Speed and Accuracy – 0.5 points reduced
  • Spatial Visualisation – 0.5 points reduced
  • Word Meaning – 0.5 points reduced

Here’s an example from a Thomas International score report showing just that:

That is why you shouldn’t simply storm through the questions to answer as many as you possibly can, and also shouldn’t be too careful, on the other hand.
Finding the balance between speed and accuracy is crucial for a high score on the Thomas GIA test.


Scoring Is Based on Percentiles

All your scores will be presented as a percentile score (of what percent of past test-takers your score is higher). For instance, if you have scored in the 75th percentile, you have scored higher than 75% of test-takers.

The Thomas International GIA Test score percentiles are defined:

  • Low – 4-15 percentile
  • Below Average – 16-34 percentile
  • Average – 35-65 percentile
  • Above Average – 66-85 percentile
  • High – 86+ percentile
