Background: To understand and apply the results of multisite impact studies, it is necessary to know the extent to which the components of an intervention were implemented as they were designed in each context (e.g., Carroll et al., 2007; Hill, Corey, & Jacob, 2018). Rigorous and cost-effective measures of implementation fidelity can help…

This study used the standard setting to establish cutscores for the fidelity of implementation of an evidence-based intervention, the Self-Determined Learning Model of Instruction (SDLMI) designed to enhance goal-directed actions in secondary students with and without disabilities. Cutscores were then applied to fidelity data from a large,…

Although our field has made significant progress in the measurement of procedural fidelity in research studies, we argue for a more nuanced and expansive perspective on procedural fidelity. Specifically, we review the status quo of procedural fidelity measurement in intervention research along with specific suggestions for increasing both…

This study used standards setting to establish cutscores for the fidelity of implementation of an evidence-based intervention, the Self-Determined Learning Model of Instruction, designed to enhance goal-directed actions in secondary students with and without disabilities. Cutscores were then applied to a fidelity data from a large, randomized…

Many early childhood programs are not prepared to meet the needs of children who have significant social, emotional, and behavioral challenges. "Program-Wide Supports for Pyramid Model Implementation" (PWS-PMI) provides a systematic approach to supporting early childhood programs using Pyramid Model practices and enhancing children's…

In community interventions more generally, the concept of fidelity refers to the degree to which a program is delivered as intended. The present paper discusses ways in which fundamental aspects of participatory research challenge the concept of fidelity and differ from more traditional science-dominated approaches. We begin with a discussion of…

Purpose: This systematic review aimed to examine the effectiveness of the Social Communication, Emotional Regulation, and Transactional Support (SCERTS) Model--based interventions in supporting developmental skills of children who were diagnosed with or at increased likelihood of autism. Method: We searched six electronic databases, in addition to…

Despite the increase in federal tiered evidence initiatives that require the use of rigorous evaluation designs, such as randomized experiments, there has been limited guidance in the evaluation literature on practical strategies to implement such studies successfully. This paper provides lessons learned in executing experiments in applied…

The effectiveness of behavioral interventions can be dependent on the fidelity with which practitioners design and implement those methods. Fidelity refers to the degree to which interventions are implemented as intended. Interventions implemented with low fidelity do not achieve anticipated results with students, whereas high-fidelity…

The purpose of this study was to examine self-determination outcome data in the year following a one-year cluster randomized controlled trial (C-RCT) comparing the impacts of a "Self-Determined Learning Model of Instruction" (SDLMI) only condition to a SDLMI + "Whose Future Is It?" (SDLMI + WF) condition. Using multilevel…

This study explored teacher perceptions of their ability to implement the Self-Determined Learning Model of Instruction (SDLMI) with fidelity and the impact of these perceptions on student self-determination outcomes on the Self-Determination Inventory: Student Report (SDI:SR). Using a piece-wise growth model, we found stability in teacher…

As implementation scientists know well, evaluating fidelity is essential for researchers and practitioners when making sure they implement a plan as intended. However, the concept of fidelity remains unclear, given that various conceptualizations exist within and across disciplines. To help researchers and practitioners understand fidelity, a…

Implementation of multi-tiered systems of support is occurring within and across a number of countries with an increased recent focus on the development of local system capacity to maintain high levels of practice implementation fidelity. The purpose of this paper is to describe the importance of local capacity development in the high fidelity and…

Coaching is becoming widely recognized as a tool to help early childhood educators enhance teaching and build professional skills. Although effective, the use of an external coach can be cost and time prohibitive. This study examined the effectiveness of internal peer coaches as compared to external coaches in implementation fidelity of an…

Scaling up educational interventions in the STEM (Science, Technology, Engineering, and Mathematics) field is critical but under-researched. We review and draw implications from a series of studies investigating the long-range impact of an implementation of an early mathematics scale-up model based on learning trajectories. Lasting effectiveness…
