GRE Psychology Subject Test – GRE Scoring Process
The GRE subject test is a conventional paper-based test, which uses the Score Equating method for its scoring process. It is a statistical process that helps in determining comparable scores on different forms of the subject test. The scores of this test are calculated by adjusting the number of questions correctly answered accordingly to the rising difficulty of the questions with each test form. Hence, the reported score may not tally with the number of correct answers given on different test forms.
In this conventional GRE subject test, the difference in the level of difficulty between the test forms is comparatively less. The method of score equating calculates the scores of these different test forms.
Two Step Process:
The scoring process of the subject tests includes two steps:
- The first is the computation of raw score. Calculate the score for the correct number of answers and then subtract one fourth of the total score of the number of questions answered incorrectly and you will get the raw score.
- The second step is the conversion of the raw score to a scaled score. This conversion of the scores is done through the process of score equating. The score equating helps in adjusting the differences in the difficulty level between the test forms. Thus, this process of score equating gives you the final scaled score irrespective of the difficulty level past subject test editions.
Score Scales of the Subject Test:
The scores of the subject test are divided into two: the total score and the sub-score.
The total score is reported in 10-point augmentations on a 200-990 score scale. However, this range of score may be smaller for a particular subject test.
The sub-score for the psychology subject test is reported on a 20-99 score scale, in 1-point augmentations. However, this range of sub-score is usually smaller for a particular subject test.
