The Effectiveness of DIBELS Oral Reading Fluency for Predicting Reading Comprehension of High- and Low-Income Students

Correlations and sequential analyses between performance on Dynamic Indicators of Basic Early Literacy Skills–Oral Reading Fluency (DORF) and reading achievement on the Stanford Achievement Test–Tenth Edition (SAT-10) during 2003–2004 were examined for high- and low-income children. Participants were 215 third graders, 112 above and 103 below proficiency benchmarks for DORF. For below benchmark students, DORF scores strongly predicted SAT-10 comprehension. For above benchmark students (a) DORF scores predicted comprehension for high- but not low-income students; (b) statistically significant differences in reading fluency, comprehension, and vocabulary existed between high- and low-income students; (c) reading vocabulary equally predicted comprehension for students of differing economic backgrounds; and (d) reading fluency did not predict comprehension for low-income students beyond what was accounted for by vocabulary.
