The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of initial variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of pretest variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

Purpose: The purpose of the study was to investigate child- and intervention-level factors that predict improvements in functional communication outcomes in children with motor-based speech sound disorders. Method: Eighty-five preschool-age children with childhood apraxia of speech (n = 37) and speech motor delay (n = 48) participated.…

Behavior intervention plans (BIPs) are intended to help educators systematically support students with behavioral problems at school. Previous research confirms that the effectiveness of a BIP depends on the degree to which the plan is technically adequate and implemented with integrity. What remains unclear from the literature is how professional…

Students with or at-risk of High Incidence Disabilities (HID) experience negative short and long-term outcomes. To intervene, many schools have elected to implement evidence-based practices within Multi-Tiered Systems of Support (MTSS), such as Response to Intervention (RTI). MTSS target the academic and behavioral progress of students deemed 'at…

Purpose: Bayesian-based models for diagnosis are common in medicine but have not been incorporated into identification models for dyslexia. The purpose of the present study was to evaluate Bayesian identification models that included a broader set of predictors and that capitalized on recent developments in modeling the prevalence of dyslexia.…

High-quality Tier 1 instruction is frequently conceptualized as the "foundation" for other tiers of intervention within multitiered systems of support (MTSS) models. However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness. The purpose of this study was to…

The relationships between response to intervention (RTI) data, cognitive ability, academic achievement, identification methods, and specific learning disability (SLD) identification have been studied extensively in recent years; however, an empirically supported method of identifying a learning disability has yet to be agreed upon. Without a…

Early identification of learning difficulties is a critical component of the Response to Intervention (RtI) model. In kindergarten, the screening of foundational reading skills can provide a data-based guideline for identifying students requiring a more intensive response-based intervention before starting elementary school. This study examines…

Data from a randomized control trial of a multi-component intensive reading intervention were analyzed to determine the proportion of students nonresponsive to intervention and to identify predictors of nonresponse. Participants included 216 first-grade students identified as at-risk for reading difficulties. Response to intervention was…

High-quality Tier 1 instruction is frequently conceptualized as the "foundation" for other tiers of intervention within multi-tiered systems of support (MTSS) models (Gersten et al., 2009). However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness (Hill et al.,…

The aims of this study were to examine speech-language pathologists' (SLPs) knowledge and consideration of factors found in research when making clinical decisions regarding AAC for children with Autism Spectrum Disorder (ASD), and to reveal additional factors identified based on SLPs' clinical practice. A 20-question mixed-methods survey was…

Inadequate responders demonstrate significant risk for learning disabilities. Previous investigations of the cognitive profiles of inadequate and adequate responders have not included measures of executive functions (EFs), which have well-documented associations to reading comprehension. We evaluated EF performance on a common factor comprised of…

Check In Check Out (CICO) is one of the most empirically supported Tier 2 behavior interventions for students who require additional supports to experience success. CICO incorporates regular performance feedback and adult interaction throughout the day in alignment with school-wide expectations. Performance feedback includes both reinforcing and…

The goals of the study were to (a) examine teacher-reported acceptability of a daily report card (DRC) intervention for a student in their classroom prior to and during implementation; (b) examine factors that predict acceptability; and (c) explore the relations between teacher-reported acceptability, student and teacher characteristics prior to…
