We have played a catalytic role in helping Achievement First (AF) to replicate its K-8 math program to selected partner schools in New York City outside AF’s traditional charter network through a train-the-trainer model. Leap Educational Consulting (LEAP), the trainer and now a standalone organization, is supporting district and charter schools across 20 states to implement math curriculum and build instructional capacity that drive student achievement at their schools. The model leverages intensive coaching and tools that enable schools to effectively implement AF’s Accelerate curriculum. We are supporting LEAP in testing the model’s efficacy at schools that are using alterative math curricula. Initial results demonstrate success. In its pilot year as a standalone organization, 100% of all LEAP’s NY school partners averaged proficiency growth of 5% or higher on the NY State Exam, with 50% experiencing an average proficiency growth of 10% or higher.
