Overview

Mission

A tuition-free Public Charter School empowering grades K-8 to embrace the wonders of science, technology, reading, engineering, arts, and mathematics.

What it reported doing in 2024

School activities are focused on the stream approach which is developed with reading/writing/artisitic components. Windham Academy provides students with an exceptional learning experience while increasing students interests in science, engineering, and math through technology. The school provides 180 days of school year instructional programming each year.

Operating model

Revenue model
Grant-funded. 87% of the money available for current operations came from government grants.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Some filing-based governance responses are negative or unanswered and expenses are high relative to revenue.
