How To Convert T-Scores To Percentiles

T-Scores are mostly used on standardized psychological tests and some medical tests. The scores are designed so that a score of 50 is considered average and the standard deviation is 10. These scores are easily converted into other standardized measurements. You may use a standardized score conversion chart to convert T-scores to percentiles for example. These charts are widely available online and make the conversion a simple task that anyone may perform.

Step 1

Open a score conversion table in your Internet browser (see Resources).

Step 2

Locate the line that shows the T-score you wish to convert.

Step 3

Trace the line to the percentile column to see the corresponding percentile.

Things Needed
