Our impact
Measured, not assumed.
Every NextGEN STEM cohort is evaluated with matched before and after assessments. We track what girls know, how they see themselves, and what they want to become, and we share what we learn, including what still needs work.

The model works in the classroom.
77 girls at two Ohio schools, one an urban all-girls public school in Cleveland and one a suburban STEM school in Kettering, completed matched assessments before and after the 12-week program.

How we measure
Built-in evaluation, every cohort.
Start with a baseline
Girls complete an assessment before the first lesson, so every gain is measured against where they started.
Fit the tool to the age
Our youngest learners answer picture-based questions read aloud by a facilitator, so reading level never hides what they know.
Track attendance
We record how many weeks each girl attends, so we can see how participation shapes results.
Match, report, adjust
Before and after answers are matched by student, reported to partners and funders, and used to improve the next cohort.
What we're learning | Summer 2026
Results follow attendance.
In summer 2026, we tested Girls of Tomorrow outside the school day for the first time, at two Boys and Girls Clubs of Northeast Ohio sites. The curriculum's core concept still landed. But attendance varied far more than in school, with families facing transportation, sibling care, and moves, and results tracked closely with how many weeks girls could attend.
The lesson shapes how we grow: in community settings, access supports like transportation and caregiving help need to be part of the program design, not an afterthought.
