ELLPro’s approach is backed by independent evaluations from Johns Hopkins University’s Center for Research and Reform in Education (CRRE).
These studies reviewed our tutoring program design and measured its impact on student achievement, highlighting how ELLPro’s model can accelerate growth and close learning gaps for English learners.
The Johns Hopkins University Instructional Design Review evaluated the quality and rigor of our tutoring program’s design, curriculum, and delivery model. The review examined program design, content selection, evaluation methods, and the user experience for educators and students.
Findings confirmed a strong, evidence-based framework:
The Design Review rubric includes thirteen evaluative criteria organized into four broad categories.
For each category, a rating of Limited (
