MetaMetrics, creator of the Lexile Framework for Reading, and Carnegie Learning have launched benchmark reading assessments that give educators insight into students' reading ability. They are available this fall in Carnegie Learning's Lenses on Literature 6-12 English Language Arts curriculum. The system includes grade-banded locator tests and beginning-, middle-, and end-of-year benchmarks. Lexile measures place student ability and text complexity on one scale, helping teachers choose suitably challenging reading material and track growth. "Lexile measures build on the support already embedded in Lenses on Literature," said Barry Malkin, chief executive officer of Carnegie Learning. Research on the Lenses model found students gained four to nine additional months of learning in one school year compared with peers. The model has reached more than 2.4 million students.
