Year One Cost Example

In this example, a school district implements Whole Number Foundations Level K in four elementary schools, each with two kindergarten classrooms. One instructional assistant at each school delivers the program to a group of five at-risk students in each classroom. The district also arranges three in-class coaching sessions spread over the course of implementation.

Training: 2 sessions @ $2,000/session
Intervention Kits: 4 @ $399/kit
Additional Student Worksheets: 4 sets @ $102/set
Coaching: 3 sessions at $2,000/session

With 10 students served in each of 4 elementary schools, 40 students would receive the program in Year 1. The per student expense would be $300.10.
