Grounded in the simple view of reading, this study tracked the development of print-processing skill in high-, average-, and low-achieving readers at six time points across grades 1-3. Results showed large between-group differences in sight vocabulary, oral reading accuracy, and oral reading rate that remained stable from beginning of first grade…

We examined which of two instruments (Text Reading and Comprehension inventory [TRC] or a traditional informal reading inventory [IRI]) provides the more valid assessment of a primary-grade student's reading instructional level. The TRC is currently the required, benchmark reading assessment for students in grades K-3 in the state of North…

After considering the relationships between (a) reading fluency and reading rate and (b) reading rate and sight vocabulary, this study addressed a very practical question. Can a cut score on a sight vocabulary task (1-min) predict level of reading fluency 4+ months into the future? The prediction was tested at multiple times point across grades…

Reading comprehension growth trajectories from 3rd to 7th grade were estimated for 99,919 students on a state reading comprehension assessment. We examined whether differences between students in general education (GE) and groups of students identified as exceptional learners were best characterized as stable, widening, or narrowing. The groups…

The present study investigated the relationship between rapid recognition of individual words (Word Recognition Test) and two measures of contextual reading: (1) grade-level Passage Reading Test (IRI passage) and (2) performance on standardized STAR Reading Test. To establish if time of presentation on the word recognition test was a factor in…

This longitudinal study investigated children's performance on several informal reading and spelling tasks. Students (n = 274) in a rural North Carolina county were assessed across grades 2 to 6 on the following measures: isolated word recognition (timed and untimed), oral reading accuracy, reading comprehension, reading rate, and spelling.…
