ValidityConcurrent Validity of Estimated Oral Reading ScoreDescriptive statistics and correlations between the STAR Early Literacy Raschscores and DORF raw score (measured in words read correctly within a minute[WCPM]) are provided in Table 29. All correlations were statistically significant(p < 0.01). Scatterplots of the relationship between STAR Early Literacy Raschscores and WCPM on the benchmark passages of DIBELS are shown in Figures8–10.Table 29:Correlations between STAR Early Literacy and DIBELS Oral Reading FluencySTAR Early LiteracyRasch ScoreDIBELS WCPMGradeNMean SD Mean SDCorrelation1 2,028 1.38 0.96 37.96 27.70 0.682 729 1.53 0.93 49.20 27.43 0.633 464 2.18 1.06 71.06 31.93 0.65Figure 8:Scatterplot of Grade 1 DIBELS Oral Reading Fluency Score (DORF WCPM)and STAR Early Literacy Rasch ScoreSTAR Early LiteracyTechnical Manual78
