This technical report describes the development of fifth grade progress monitoring measures in the area of Passage Reading Fluency. This measure was designed to target the fluency component of a developmental model of reading. Twenty alternate forms were written by graduate students and reviewed by the lead author. The passages were piloted and mean scores were compared as a measure of difficulty. In response to these data, the passages were brought into closer alignment by identifying nine passages that showed similar difficulty level and adjusting the remaining passages to match this level. Data on the difficult of each passage and a summary of revisions are presented. Appended are: (1) Test Specifications for Creating Passage Reading Fluency Measures; (2) Example Fifth Grade Passage Reading Fluency Test: Student Copy; and (3) Example Fifth-Grade Passage Reading Fluency Test: Assessor Copy. (Contains 4 tables.)
