What do Percentile Mean in a Test Report?
Percentiles ARE NOT equivalent to scores. They are calculated based on scores, but tell us that the child performed better than x% of the population. For example, a child that received an average score will be in the 50th percentile. This means that he or she scored better than 49% of the norm group, but was outscored by the other half of the norm group. Scoring in the 50th percentile is NOT equivalent to receiving a score of 50.
