The Colorado Charter School Institute (CSI) is a statewide charter public school authorizer. Our mission is to foster high-quality charter public school options for all students. CSI oversees schools across Colorado, from Fruita to Aurora, Durango to Steamboat Springs.

We believe that every child should have access to high-performing school choices. Accordingly, we seek to foster a portfolio of high-quality charter public school options that offer diverse educational models to meet the needs of every child.

Our approach to authorizing balances autonomy and accountability. As such, we offer our schools flexibility to choose the methods to best meet the needs of their students. In return, we hold them accountable to clear expectations for performance.

We Serve All Students

Charter schools are public schools. As such, CSI schools are tuition-free and open to all students.

CSI students are comparable to the state averages for students of color, multilingual learners, and students with a 504 plan.

And, importantly, CSI continues to increase service to students with special needs.

We Hold Our Schools Accountable for High Performance

CSI holds its schools accountable for academic, financial, and operational performance. Importantly, nearly 3 out of 4 CSI schools earned the state’s highest academic rating.
