Each year thousands of new titles are analyzed for text difficulty, or readability, and the results are reported in terms of DRP units.
Because the same DRP units are used for reporting student performance on DRP tests and for reporting text difficulty, student reading ability and text difficulty can be directly linked.
Teachers using textbooks or popular titles that are not listed in DRP-BookLink or on our website may call Questar at 800-800-2598 to make arrangements for submitting those books for DRP readability analysis. The service is also available to publishers, librarians, curriculum planners, and other school administrators.
