When using T-Scores, the mean (average) is always 50, and the standard deviation is 10. If your T-Score is above 50, then it is above average. If your score is less than 50, it is below average. For example, if you have a T-Score of 60, you scored higher than 84% of all organizations.T-Scores are distributed in a bell-shaped curve, as illustrated in the diagram to the right. 68% of T-Scores fall between 40 and 60. 96% of scores fall between 30 and 70.f your score is less than 50, it is below average. For example, if you have a T-Score of 60, you scored higher than 84% of all organizations. T-Scores are distributed in a bell-shaped curve, as illustrated in the diagram to the right.
