Impact evidence
Describes programs. Its tax return describes what it does but we have found no measurable results in it.
Programs described in its return (1)
- $9.5 million spent. The tuition-free, public charter school enrolled 927 students at the beginning of the FY 25/26 school year in grades K through 12 compared to 884 students in the prior year. In April 2023, the State Board of Education approved a 7-year charter renewal for the School.The School operates within a "small school" environment organized around smaller, more personalized units of adults and students, giving students a better chance of being known and noticed. However, small schools are more than just small in size and function; they are formed around three core principles: academic rigor, personalized relationships, and relevance to the world of work.
