As a standard score gives a position in relationship to a reference group, the score by itself is meaningless without knowing the position of the student when compared to all students who took the same test. A standard score of 90, the beginning of the average range, corresponds to a percentile rank of 25.A standard score of 110, the uppermost end of average, has a percentile range of 75. So a child at the 30 th percentile on a test of reading or math is performing within the region of what would be considered âaverage.â.With percentile ranks and standard scores, the comparison group matters.s a standard score gives a position in relationship to a reference group, the score by itself is meaningless without knowing the position of the student when compared to all students who took the same test.

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.
