This study examined the effects of Reading Intervention for Adolescents (RIA) and a mentoring intervention (MI) implemented for 1 year with ninth-grade English learners (ELs) with reading difficulties. Eligible students enrolled at three urban high schools were randomly assigned to the RIA (n = 142), MI (n = 163), RIA and MI (n = 164), or…

When recommending a program to achieve objectives such as improving learning outcomes for middle school students, school psychologists need information about cost-effectiveness to identify the best fit for student needs and school budgets. However, few cost studies of evidence-based instructional programs exist. We compared the cost-effectiveness…

This study examined the differential effects of Strategies for Reading Informational Text and Vocabulary Effectively (STRIVE) on the vocabulary, reading comprehension, and content learning among 4,757 fourth-grade students with and without disabilities. Schools were assigned to one of three conditions: researcher-supported professional development…

We examined the effectiveness of a researcher-provided reading intervention with 484 fourth graders with significant reading difficulties. Students were randomly assigned to one year of intervention, two years of intervention, or a business-as-usual comparison condition (BAU). Students assigned to two years of intervention demonstrated…

This study examined the effects of Reading Intervention for Adolescents, a 2-year extensive reading intervention targeting current and former English learners identified as struggling readers based on their performance on the state accountability assessment. Students who enrolled at three participating urban high schools were randomly assigned to…

English learners with learning disabilities (LD) have well-documented difficulties comprehending text. This study examined the effects of an intensive reading intervention (Reading Intervention for Adolescents [RIA]) on reading outcomes (word reading, vocabulary, and comprehension) for ninth-grade ELs with LD (n = 85). In the RIA, students…

To address the needs of a diverse group of students with reading difficulties, a majority of researchers over the last decade have designed and implemented multicomponent reading interventions (MCRIs) that provide instruction in multiple areas of reading yielding mixed results. The current study evaluates whether students' baseline word reading…

In this study, we examined the extent to which teachers' treatment adherence, instructional quality, and the interaction of these variables influenced eighth-grade students' content knowledge and reading comprehension. We examined treatment fidelity for students (n = 775) in classes randomly assigned to receive an evidence-based content area…

Students who enrolled at three participating urban high schools were randomly assigned to…

Treatment fidelity data (descriptive and statistical) are critical to interpreting and generalizing outcomes of intervention research. Despite recommendations for treatment fidelity reporting from funding agencies and researchers, past syntheses have found treatment fidelity is frequently unreported (e.g., Swanson, "The Journal of Special…

Over the past decade, parent advocacy groups led a grassroots movement resulting in most states adopting dyslexia-specific legislation, with many states mandating the use of the Orton-Gillingham approach to reading instruction. Orton-Gillingham is a direct, explicit, multisensory, structured, sequential, diagnostic, and prescriptive approach to…

It is essential for middle school leaders to develop and promote school-wide literacy models, organizational structures that have a significant impact on the learning environment for all students in their building. However, school-wide literacy models can be difficult to implement and sustain over time. Drawing from an Office of Special Education…

This experimental study examined the efficacy of a multicomponent reading intervention compared to a business-as-usual comparison condition on the reading comprehension and content area vocabulary outcomes of adolescent students with low reading comprehension. We randomly assigned 9th-grade students with low reading comprehension to a…

We examine the efficacy of an intervention to improve word reading and reading comprehension in fourth- and fifth-grade students with significant reading problems. Using a randomized control trial design, we compare the fourth- and fifth-grade reading outcomes of students with severe reading difficulties who were provided a researcher-developed…
