Focus Area
K-12
Cobblestone's K-12 work spans a variety of studies including those commissioned by textbook publishers evaluating curriculum materials, government- and nonprofit-funded initiatives. Our experience includes teacher professional development programs, university-K-12 partnerships that bring instructional initiatives into district classrooms, and informal science education programs such as those run by science museums. We have completed numerous studies of K-12 curriculum for multiple publishers and programs including science, language arts, math and intervention programs. Through methods like classroom observations, student assessment data, and teacher and student surveys, we work to generate evidence that supports a healthy, thriving educational system for the students and teachers it serves.

SECURED BY OUR CLIENTS
$1,500,000
On a recent survey of our clients, 20 out of 21 respondents said that Cobblestone was successful in helping their organization secure external funding.
The Impact
The Challenge
One of our clients, a leading textbook publisher, needed to demonstrate the effectiveness of their middle school and high school language arts curriculum to support informed adoption decisions by districts and educators. The study had to meet rigorous, well-defined design requirements, including strict criteria for study design set by the What Works Clearinghouse (WWC).
Our Solution
Cobblestone designed and executed a randomized controlled trial (RCT) study spanning eight schools across four states (Arizona, California, Ohio, and Oregon) and three grade levels, specifically made to meet WWC design standards. The study measured the curriculum's impact on student performance, giving our client evidence built to withstand WWC’s rigorous, independent review process.
The study (Eddy et al., 2010) was reviewed by the WWC and met evidence standards with reservations with baseline equivalence satisfied for the intervention and comparison groups. It was posted to the WWC site, giving the curriculum publicly available, third-party-vetted evidence of the program's efficacy — the kind of independent validation that carries weight with districts and educators evaluating curriculum options.
Case Study
"Since I began working with them on my external funding projects in 2022, they have proven to be an indispensable partner in my research and program development efforts. The level of support provided by Cobblestone is truly exceptional. Throughout the duration of my projects, I have consistently received timely support and constructive feedback that has been vital in achieving the specific goals and objectives outlined in my proposals. Their commitment to project success ensures that every milestone is met with precision and professional insight."

"Cobblestone has been an exceptional evaluation partner for our grant program. Their work reflects the highest standards of program evaluation, but their value extends well beyond producing strong annual reports. As PI/PD of a large federal grant, I have especially appreciated their strategic guidance, project management support, and thoughtful consultation, all of which have helped us stay focused on our goals and well prepared for federal reporting requirements... They are trusted partners who bring expertise, clarity, patience, and practical wisdom to complex grant-funded work."

FAQs
Program evaluation is the systematic process of assessing whether a program is working and how well. Using social science research methods, evaluators collect and analyze data to determine a program's merit, track its implementation, and measure outcomes. For organizations running funded programs, evaluation provides the evidence base needed to improve services, satisfy funder requirements, and make the case for continuation or expansion.
Cobblestone is a boutique firm that has focused exclusively on education evaluation and applied research for nearly two decades. That means every project is led by senior evaluators with deep subject matter knowledge. We work primarily with education-focused organizations, including K-12 schools and districts, community colleges, universities, and federally funded programs, which means we understand the specific accountability requirements, stakeholder dynamics, and reporting expectations you are navigating. We bring the rigor of larger firms with the responsiveness of a close, dedicated partner.
Yes. We regularly work with organizations, schools or districts that are implementing their first externally evaluated program. Part of our role is helping clients understand what evaluation involves, what data they will need to collect, and how to build internal capacity for ongoing data use. We also work with experienced evaluation consumers who want a sophisticated partner to push the rigor of their work. In either case, we begin with a thorough planning process to ensure the evaluation design matches your goals and resources.
