The Developmental Literacy Inventory is an informal reading inventory and more. 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. Word recognition lists, spelling inventories, and an emergent literacy instrument that includes assessment of phonemic awareness and concept of word enables teachers to diagnostically assess students from kindergarten to high school. 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.
