Sustained implementation of effective behavior support systems and practices is critical for improving academic and behavior outcomes for students with and without disabilities. Although implementation studies have identified variables facilitating sustained implementation of Tier 1 behavior support systems in schools, little research exists…

The current study aimed to determine the extent to which classroom teachers' professional identity typologies predict their curriculum fidelity. A total of 332 classroom teachers participated in the current study, employing the correlational survey model. The data for the study were collected using the "Curriculum Fidelity Scale"…

The purpose of this longitudinal study was to examine patterns in implementation of Tier 2 and 3 school-wide positive behavioral interventions and supports (SWPBIS) systems to identify timings of installation that led to higher implementation of advanced tiers. Extant data from 776 schools in 27 states reporting on the first three years of Tier 2…

Introduction: College students face increased risk for a variety of mental health problems but experience barriers to treatment access. Prevention programs, including those implemented by peer educators, may decrease treatment needs and increase service access. We examined the implementation of an evidence-based eating disorder prevention program,…

This study aimed to determine whether or not curriculum fidelity can be significantly predicted by certain demographic variables and level of curriculum literacy in elementary school teachers. The study was designed as a relational survey study and involved the participation of 250 elementary school teachers. For data collection, a personal…

Teacher-level factors are theoretically linked to student outcomes in data-based instruction (DBI; Lembke et al., 2018). Professional development and ongoing support can increase teachers' knowledge, skills, and beliefs related to DBI, as well as their instructional fidelity (McMaster et al., 2020). However, less is known about how each of these…

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…

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…

This study examined teacher characteristics associated with the fidelity of implementation of a social-emotional learning (SEL) curriculum, known as Settle Your Glitter. Prekindergarten through first-grade teachers (N = 60; 52% African American, 30% White, 18% Hispanic/Latinx) from seven schools were observed delivering lessons during the first…

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.,…
