Evidence-based mathematics interventions are critical for supporting students with mathematics difficulties. In research and practice, collecting implementation fidelity is important for ensuring that all the core components of the intervention are implemented as designed. Historically, implementation fidelity has been defined as multi-faceted…

Data on implementation of school-based interventions adds highly valuable information to corresponding evaluation studies. Measuring implementation outcomes, such as fidelity or acceptability, provides information on how to improve current and future implementation processes. Moreover, analyzing intervention outcomes in combination with…

Intervention fidelity is the extent to which an individual- or systems-level student intervention is delivered comprehensively in a manner aligned with the initial plan. This first installment in a three-part series on intervention fidelity highlights the importance of ensuring classroom supports are implemented as intended and introduces…

Districts and schools are under pressure to increase student academic outcomes while meeting their various social-behavioral needs. This pressure is compounded by the responsibility of creating climates that are safe and equitable for all students where teachers can teach, and all students can learn. However, far too often, negative, and…

Treatment fidelity refers to the extent to which an intervention is implemented as planned. If researchers do not assess and report treatment fidelity, or if treatment fidelity is shown to be low, findings from intervention studies are difficult to interpret, because the intervention may not have been implemented as planned. In this article, our…

Procedural fidelity is the extent to which an intervention is implemented as designed and is an important component of research and practice. There are multiple ways to measure procedural fidelity, and few studies have explored how procedural fidelity varies based on the method of measurement. The current study compared adherence to discrete-trial…

Mindfulness-based interventions (MBIs) have been evaluated in terms of efficacy; however, little is known about implementation factors of MBIs in schools. The purpose of the current study was to systematically review MBI studies published in school psychology journals. This systematic review examined peer-reviewed MBI literature in nine school…

Naturalistic developmental behavioral interventions (NDBIs) are considered one of the best practices for autistic children and their families. Most NDBIs include a component of providing training and/or coaching to caregivers to enhance skill acquisition and generalization. The procedures to implement these NDBIs are often clearly delineated in…

Despite decades of research efforts, data-based instruction (DBI) for students with intensive intervention needs are not being widely used in practice as anticipated, and many educators have difficulties in implementing it. This systematic review aimed to examine what kinds of implementation drivers and strategies have been used to support…

American Samoa, a U.S. territory, has grappled with low reading scores similar to other mainland schools. As a result, different reading interventions were implemented over the years. The problem studied was that despite using Achieve 3000 as a reading intervention for students in the local high school in American Samoa, reading scores had…

Students cannot experience the full potential benefits of an intervention unless they are receiving the intervention. This is the second installment in a three-part series on intervention fidelity designed to highlight the importance of ensuring classroom supports are implemented as intended. This article provides guidance related to measuring and…

In intervention studies, high rates of "implementation fidelity" are important markers of a study's success; however, the definition of implementation fidelity is both complex and dynamic. In this synthesis, we examined the dimensions of implementation fidelity measured and reported in 99 studies in which researchers utilized a…

Preventing young people's cigarette smoking is a major public health priority, and smoking is especially prevalent in vocational schools. Well-enforced comprehensive school tobacco policies accompanied by preventive efforts show potential to reduce smoking, but the implementation process is crucial to achieve the intended effect. We investigate…

Student outcomes depend on the implementation of intervention practice elements, which are the specific behaviors that front-line implementers deliver as part of their direct interactions with students. Tier 1 PBIS is a well established practice in schools but existing guidance on practice elements is often conflated with guidance on…
