This article presents a fluency-based measure of reading comprehension. A part of the Vitals Indicators of Progress (VIP) system, the measure outlined here represents an alternate form to the retell-fluency measure in the Dynamic Indicators of Basic Early Literacy System (DIBELS). Measures of retell fluency provide an efficient, fluency-based tool for teachers to use in identifying the handful of children whose oral reading fluency may not adequately represent comprehension. When used in tandem with oral fluency measures, retell measures provide a vehicle for more reliably targeting classroom and school-level resources and for maximizing the efficiency and effectiveness of early reading instruction.
