Reading fluency has received a recent resurgence of attention, as it is one of the defining characteristics of good readers. Not only do differences in fluency help to distinguish good readers from poor readers, but fluency is correlated to reading comprehension. Whether fluency results from, or contributes to, reading comprehension may not yet have been determined; however it appears that both foster each other. Given this importance, fluency has become an integral recommended part of many reading programs.
