Curriculum-based measures (CBMs), which allow educators to monitor progress over time and make instructional decisions based on student performance, represent a fixture of general approaches to reading and data-based instructional frameworks. However, evidence supporting the use of CBM for students with intellectual disabilities is limited. This…

The current study compared the reading growth of (a) students who received targeted interventions, (b) students who received typical school interventions, and (c) students who were proficient readers at the study's onset. The participants were 1,513 students in first through fifth grades who attended one of three treatment schools or one of three…

We used triannual reading curriculum-based measurement of oral reading fluency data from 11,834 U.S. students in Grades 2 and 3 enrolled in an evidence-based Tier 2 reading intervention program (Reading Corps) to investigate the extent to which family involvement in the intervention might buffer against a negative effect of lower intervention…

Students with disabilities in upper elementary grades who read well below grade level often require one-to-one intensive intervention. The following study examines the effects of a combined explicit decoding plus frequency building intervention on consonant-vowel-consonant (CVC) word reading fluency. Participants were two third-grade students and…

Research supports the efficacy of intensive literacy instruction for children with moderate intellectual disabilities and Down syndrome (DS). However, much of the literature features measures closely aligned with evaluated interventions. Despite their increasing role in instruction, curriculum-based measures (CBM) are rarely featured in reading…

The transition from sounding out unfamiliar words to effortlessly reading connected text does not occur all at once nor at the same rate for students. The purpose of this study was to explore the accuracy of three decision rules (data point, median, and trend line) applied to progress monitoring outcomes of alphabetic principle (nonsense word…

Research focused on identifying effective interventions for individuals with Down syndrome is increasingly informed by the behavioral phenotype -- a profile of performance associated with a genetic abnormality. Recent studies substantiate the efficacy of phenotypically aligned instruction in improving basic reading skills for children with Down…

Once students meet exit criteria and Tier 2 reading supports are removed, many do not maintain their current progress and fail to meet future performance benchmarks. Although estimates of average growth during intervention exist, typical rates of growth after supports are removed are relatively unknown. In this research brief, we used segmented…

Brief experimental analysis (BEA) is frequently used to drive intervention selection decisions for students in need of intensive reading fluency intervention. Researchers have demonstrated that most BEA results for students with reading fluency difficulties are undifferentiated when considering the standard error of measurement (SEM) of…

To support students with disabilities who do not respond to typically effective reading intervention, special education teachers are expected to implement evidence-based practices for intensifying intervention. Data-based individualization is an effective, evidence-based practice recommended in research to intensify intervention, but requires…

We used data from the 2014-2015 easyCBM assessment system to explore the applied reading intervention characteristics in a sample of 3,074 Grade 1 students (and 5,145 interventions) in school districts applying a multitiered systems of support (MTSS) framework. We describe the number of interventions, number of assessments, the intervention start…

School psychologists regularly use decision rules to interpret student response to intervention in reading. Recent research suggests that the accuracy of those decision rules depends on the duration of progress monitoring, the number of observations available, and the amount of measurement error present. In this study, we extended existing…

Purpose: Morphological interventions promote gains in morphological knowledge and in other oral and written language skills (e.g., phonological awareness, vocabulary, reading, and spelling), yet we have a limited understanding of critical intervention features. In this clinical focus article, we describe a relatively novel approach to teaching…

This simultaneous replication single-case design study investigated a vocabulary and main idea intervention with an aspect of text choice provided to students with autism spectrum disorder (ASD). Five middle school students with ASD participated in two instructional groups taught by school-based personnel. Results were initially mixed. These…
