Baseline Equivalence: What it is and Why it is Needed

This guide is designed to help practitioners and researchers work together to design an impact study with baseline equivalence and in turn learning how to determine if an impact study is likely to produce meaningful results. This is part of a series of guides that help practitioners assess their scaling efforts critically, collect evidence on the effectiveness of their interventions, and increase the likelihood of effective scaling of successful interventions.

Scaling Evidence-Based Models (SEBM) Project

The Office of Research and Evaluation (ORE) initiated the Scaling Evidence-Based Models project to support the scaling of effective interventions. This guide is part of ORE’s Scaling Evidence-Based Models project, which includes additional resources that contribute to the study and application of scaling effective interventions. Below are additional scaling resources:

• Making the Most of Data: This guide will help practitioners maximize the use of their intervention data to help their organizations improve program implementation and provide evidence to funders about effectiveness.
• What Makes for a Well-Designed, Well-Implemented Impact Study: This guide is intended to help practitioners ensure that their evaluators produce high-quality impact studies.
• How to Structure Implementation Supports: This guide will help practitioners develop formal strategies (also known as implementation supports) to help consistently deliver an intervention as it was designed, which is especially helpful for organizations scaling an intervention and assessing implementation fidelity.
• Build Organizational Capacity to Implement an Intervention: This guide will help practitioners prepare to implement their desired intervention through building organizational capacity, which involves establishing the organizational structure, workforce, resources, processes, and culture to enable success.
• Scaling the Birth and Beyond (B&B) Intervention: Insights from the Experiences of the Child Abuse Prevention Council (CAPC): This case study describes the scaling of Birth and Beyond (B&B), a parenting education and support intervention designed to reduce child maltreatment, by the Child Abuse Prevention Council of Sacramento (CAPC) and its partners.
• Scaling the Reading Corps Intervention: Insights from the Experiences of the United Way of Iowa: This case study describes the scaling of Reading Corps, a literacy intervention designed to improve reading proficiency by United Ways of Iowa (UWI) and its partners.
• Scaling the Home Instruction for Parents of Preschool Youngsters (HIPPY) Intervention: Insights from the Experiences of Parent Possible: This case study describes the scaling of Home Instruction for Parents of Preschool Youngsters (HIPPY), a home-visiting intervention that seeks to help parents improve their young children’s development, by Parent Possible and its partners.
• Scaling Evidence-Based Interventions: Insights from the Experiences of Three Grantees: This report presents insights from a cross-site analysis of process case studies conducted with three AmeriCorps grantees engaged in scaling.
• Scaling Programs With Research Evidence and Effectiveness: This article describes a process called SPREE —Scaling Programs with Research Evidence and Effectiveness — and provides insights into conditions under which foundations can apply it to help them and their grantees scale successfully.
• Scaling Checklists: Assessing Your Level of Evidence and Readiness (SCALER): This guide describes a framework that identifies how organizations can improve both their readiness to scale an intervention and the intervention’s readiness to be scaled, so that intervention services are best positioned to improve outcomes for a larger number of participants. Each checklist in the SCALER provides summary scores to reflect how ready an intervention and organization might be for scaling.
• Planned Scaling Activities of AmeriCorps-Funded Organizations: This report is designed to generate both practical knowledge about how AmeriCorps and other funders can successfully scale effective interventions.
• Evidence of Effectiveness in AmeriCorps-Funded Organizations: This report is designed to help inform the agency’s interest in identifying the intervention components that are critical for an intervention’s effectiveness.
• Scaling an Intervention: Recommendations and Resources: The guide provides five key recommendations that will help funders like AmeriCorps, other government agencies, and philanthropic organizations identify which funded interventions are effective, enhance their knowledge base on scaling them, and pursue scaling.
