There is an extensive body of research establishing measures of oral reading fluency as valid and reliable predictors of important reading outcomes and performance on high stakes tests (Good, Simmons, & Kame'enui, 2001). The present study was conducted to determine whether these findings also apply to the Florida Comprehensive Assessment Test as a measure of reading outcomes and achievement of Florida's reading standards for third graders. Specifically, the authors wanted to determine whether performance on brief, one-minute measures of oral reading fluency are predictive of achievement in reading as measured by the reading portion of the Florida Comprehensive Assessment TestSunshine State Standards (FCAT-SSS). If these measures reliably predict performance on the FCAT-SSS, then teachers might use them as "early warning signs" that students may, or may not, succeed on the FCAT-SSS. Thirteen schools from one Florida school district provided data, which included curriculum-based measures of oral reading fluency (ORF) and FCAT scores for third grade students (N=1102). ORF scores were obtained in May 2002, and the FCAT was administered in April 2002. Although the correlations between ORF and FCAT-SSS performance are roughly similar across racial/ethnic groups, scores above 110 correct words read per minute are slightly less predictive of success for minority groups, while scores below 80 cwpm are more predictive of failure for these groups. This relationship likely attains because children from minority groups are typically weaker than white students in other reading skills, such as vocabulary, which also predict reading comprehension. Thus, for minority children (particularly African Americans), achieving the benchmark of 110 words per minute was not as strong a guarantee of success on the FCAT as it was for the white students in this study. Conversely, if a minority student attains an oral reading score below 80, there is a greater likelihood of performance at level 1 or 2 on the FCAT than for the white students in this study.
