Due to the differences in difficulty between texts, Literably will often, though not always, report an equated score. In these cases, the reported score is the equated score and the raw score is the original words correct per minute score. The equated score may be slightly higher (when a student reads a difficult text) or slightly lower (when a student reads an easy text). These scores are generated statistically using Literably's internal data.
For progress monitoring and screening purposes, equated scores are superior to raw scores, where available. They ensure that the conclusions drawn about a student's fluency rate reflect her true abilities rather than random fluctuations driven by text difficulty.
In general, Literably will not report an equated score if it is 20 words higher or lower than the raw WCPM score.
