This study examined the relationships between silent and oral reading fluency and comprehension. Findings indicated that fourth grade students had consistent levels of comprehension in both reading modes. Students of all reading levels showed a similar pattern across the segments of a text set in both oral and silent reading--a gradual increase in rate from texts one through three, a drop-off on text four, and the fastest speed on text five. A portion of the sample engaged in abnormally rapid silent reading relative to their oral reading rates coupled with low comprehension. Implications for instruction are discussed.
