Its graded word recognition lists and reading passages, all written especially for this instrument, allow teachers to assess students’ silent and oral reading comprehension, fluency, and word recognition with narrative, social studies, and science passages at reading levels from Primer to high school.  Complete with word recognition lists, spelling inventories,  emergent literacy instruments that include assessment of phonemic awareness and concept of word, and a phonics assessment instrument enables teachers to diagnostically assess students from kindergarten to high school.  Unlike any other book, students’ reading levels are reported out as both grade equivalents and Lexiles©, simplifying the task of matching students to thousands of books at their independent and instructional reading levels.

Comprehension questions about each reading passage tap a wide range of comprehension skills including recall of explicitly stated information, inferential thinking, and vocabulary usage.  Two equivalent forms of the inventory allow retesting at the same levels with different passages.

Complete instructions are given for using the DLI for screening, diagnostic, and monitoring assessment.
