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…

While the long-term societal costs for youth with disruptive behavior disorders are well documented, there is a dearth of information about the comprehensive costs of implementing even the most well-regarded early intervention programs, and the costs of scaling effective interventions are even less well understood. This study estimated the costs…

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 transition to kindergarten is an important time in the young life of a preschooler. Research has shown that the quality of children's kindergarten transition processes has implications for their future academic and social outcomes, and the level of family engagement in kindergarten. Research further indicates that children living in families…

Accumulating research has established explicit mathematics instruction as an evidence-based teaching practice. This study utilized observation data from a multi-year efficacy trial to examine the longitudinal effects of a core kindergarten mathematics program on the use of explicit mathematics instruction among two distinct groups of teachers: one…

States increasingly are incorporating Kindergarten Entry Assessments (KEAs) into their comprehensive assessment systems with the goal of helping educators identify gaps in children's competencies, target instruction to children's individual needs, engage parents to better support their child's learning, and identify needs for expanding and…

Oregon's Effective Behavioral and Instructional Support Systems (EBISS) initiative was implemented in 25 school districts. The initiative trained and coached district leaders and teachers in the use of the EBISS model through the lens of implementation science. The EBISS model integrates school-wide positive behavior intervention and supports…

This study examined the impact of Oregon Reading First on student reading outcomes. Outcomes in schools that began Reading First implementation in 2003-2004 (Cohort A) were compared to outcomes in schools that began Reading First implementation in 2005-2006 (Cohort B). The primary hypothesis, that experienced Cohort A schools would outperform…

First Step to Success is a collaborative home and school early intervention program designed to address secondary prevention goals and outcomes for behaviorally at-risk children in the K-2 age-grade range (see Walker, Kavanagh, Stiller, Golly, Severson, & Feil, 1998; Walker, Stiller, Golly, Kavanagh, Severson, & Feil, 1997). In 1999 the…
