We investigated influences of non-alphanumeric rapid naming on decoding skill growth for regularly and irregularly spelled English words. In a longitudinal study, 52 at-risk and 69 not-at-risk readers were tracked from Grade 1 to Grade 3. Non-alphanumeric rapid naming ability measured in Grade 1 accounted for unique variance in irregular word…

The purpose of this study was to examine the role of a dynamic assessment (DA) of decoding in predicting responsiveness to Tier 2 small-group tutoring in a response-to-intervention model. First grade students (n = 134) who did not show adequate progress in Tier 1 based on 6 weeks of progress monitoring received Tier 2 small-group tutoring in…

This study investigated the predictive validity of a dynamic assessment designed to evaluate later risk for reading difficulty in bilingual Latino children at risk for language impairment. During kindergarten, 63 bilingual Latino children completed a dynamic assessment nonsense-word recoding task that yielded pretest to posttest gain scores,…

This study assessed the effects of sampling breadth on technical features of word identification fluency (WIF), a tool for screening and monitoring the reading development of first graders. From a potential pool of 704 first-grade students, the authors measured both a representative sample (n = 284) and 2 other subgroups: those with low reading…

This article compares 2 fluency-based assessments of letter sound knowledge: letter sound fluency and nonsense word fluency (NWF). Ninety-one children were administered both assessments 5 times during the second half of kindergarten. The assessments were comparable for concurrent and predictive criterion-related validity at single points. The…
