Here's an update on Pearson test scoring errors in NY, which has many public gifted & talented programs and several schools that require 97% scores.
"According to Pearson, three mistakes were made. Students’ ages, which
are used to calculate their percentile ranking against students of
similar age, were recorded in years and months, but should also have

formula used to combine the two test parts into one percentile ranking
contained an error."
Calculation errors affected 4,735 students - Click here for the complete NY Times piece.
