This study examined the predictive validity of combinations of progress-monitoring measures: (a) curriculum-embedded phonemic awareness and alphabetic/decoding measures, and (b) Dynamic Indicators of Basic Early Literacy Skills (DIBELS; Good & Kaminski, 2002) nonsense word fluency and phoneme segmentation fluency on reading outcomes of kindergarten students in a tier 2 intervention. Results of multiple-regression analyses indicated that curriculum-embedded mastery checks and DIBELS measures each explained a significant amount of variance on the outcome measure. However, curriculum-embedded measures explained statistically significantly more variance at each time point supporting their utility in documenting progress of kindergarten students receiving intervention.
