The Developmental Reading Assessment (DRA) is an individual reading assessment designed to assess students� reading performance in Grades K-3 and Grades 4-8. A second edition of the DRA has been developed. The DRA2 adds new fiction and nonfiction benchmark assessment books, replaces and revises some of the original benchmark assessment books and modifies the assessment procedures for transitional and extending readers so there is a smoother transition between the DRA2, Grades K-3, and DRA2, Grades 4-8.
