What we do

The last 20 years have witnessed an encouraging shift in the nonprofit sector: organizations increasingly measure their impact and consider how to reallocate resources in light of data. Yet, the shift has also introduced new challenges:

  • Organizations focusing singularly on measuring impact without revisiting theory, design, and implementation issues;
  • Gaps in knowledge and understanding about data systems and applications among nonprofit staff members;
  • Absence of strong evaluation culture to support internal evaluation and performance management efforts.

We offer three services to meet this need:

Evaluation consulting

These are close partnerships between Glass Frog and the client wherein we identify potential breakdowns in program theory, design, or implementation, probe the existing systems meant to support evaluation and continuous learning, and build solutions. These engagements can be short-term (six months to a year) or continue from year-to-year as organizations gradually build their internal capacity for evaluation. A case study from an evaluation consulting engagement can be found here.

Independent evaluation

We provide mixed methods formative and summative evaluation services aimed at answering specific questions and offering actionable solutions. We have experience working on both smaller-scale evaluations of program implementation and processes as well as larger-scale, multi-year impact evaluations. Deliverables include monthly or quarterly progress reports, as well as final reports with detailed recommendations for how a program can modify theory, design, or implementation to improve its ability to impact outcomes.


We offer customized trainings for nonprofit staff, ranging from one-day workshops to longer-term coaching engagements. Our trainings can be differentiated for front-line staff, program managers, or leadership teams. Our longer-term coaching engagements allow us to work in-depth over a period of six to twelve months with staff members in applied settings to help them learn to ask the right questions about their programs and identify simple ways to answer those questions.
