The Degrees of Reading Power® (DRP®) Program is the basis of a highly regarded line of reading comprehension tests for students in grades 1 –12+. The tests are criterion-referenced and allow precise tracking of a student’s reading development over time.

Primary and Standard DRP tests are holistic measures of how well students understand the meaning of text. Test results are reported on the DRP Scale of Text Difficulty – the same scale that is used to measure the reading difficulty of printed material. By linking students’ DRP test scores with the readability values of books, teachers are able to locate, assign, or recommend textbooks, literature, and popular titles of appropriate difficulty to their students.

The Readability of Textbooks database – NOW ONLINE – and software known as DRP-BookLink provide that link.

Advanced DRP tests extend the definition of reading comprehension by assessing how well students are able to reason with textual materials.
