The formula for calculating a T-score is: T-score = 50 + [10 x ((raw score â mean)/SD)]. The mean and SD for a pre-clinical course are based on students taking the course during the same offering (time period). For clerkships, the mean and SD are based on active students applying for residency in the same year.
We'll begin with z scores. z scores can be computed by equating the mean of the raw score distribution to 0.00 and the standard deviation to 1.00. T-scores are directly related to z scores. With T-scores, the mean of the raw score distribution is equated to 50, and the standard deviation is equated to 10. Therefore, a z score of +1.00 would be equal to a T-score of 60. In general z scores are expressed as decimals carried out to the hundredths place and T-scores are expressed as whole numbers. Thus, a z score of -3.00 is equal to a T-score of 20.
