What are the “normed Lexile” values that display on the graphs?

The normed Lexile values come from a linking study between the LitPro Test and the Lexile Framework for Reading, using a sample of 512,224 students in a medium-to-large U.S. state. The sample’s distributions of scores on norm-referenced and other standardized measures of reading comprehension are similar to those reported for national distribution.

These normed Lexiles can be used to provide information on how a given student performed in relation to other students of the same year/grade level. The normed Lexile values used in Literacy Pro are the 50th percentile of the distribution of scores for that particular year/grade level.
