1. NPR stands for National Percentile Rank.
2. The National Percentile Rank is based on the mean NCE score for each group.
3. Mean scaled scores for groups in counties, districts, or schools whose student scores are based on mixed numbers of days of instruction should not be used to compare the performance of one school, district, or county with another.
