If a subtest T-score is 60, what does this indicate relative to the mean of 50 with a standard deviation of 10?

Explanation:
T-scores are centered at a mean of 50 with a standard deviation of 10, so each 10-point move represents one standard deviation. A score of 60 is 60 − 50 = 10 above the mean, which equals one standard deviation. So this indicates the result is one SD above the mean—above average relative to the reference group. In normal terms, that corresponds to about the 84th percentile.
