Cornerstone Chartered Public School

Cornerstone empowers children in the Upper Valley to become strong readers, thinkers, and leaders with an equitable, free, literacy-first public education. Our vision is of a future where all children rise with the power of literacy.

Cornerstone Chartered Public School is a tuition-free, open-enrollment, K–8 public school serving New Hampshire's Upper Valley. As the only charter school within 50 miles of Lebanon, Cornerstone provides families in northern Sullivan and southern Grafton counties with a high-quality, equitable public school option that unlocks every child's potential.

Grounded in the Science of Reading, every student at Cornerstone learns through the Orton-Gillingham Approach, a structured, multisensory, research-based method proven effective for all learners, including those with dyslexia. Our content-rich curriculum integrates literacy, math, science, and the arts to build critical thinking and knowledge. Small, multi-age classes foster personalized learning, and every teacher is trained and certified in Orton-Gillingham.

Why It Matters

Two-thirds of New Hampshire students read below grade level. In Sullivan County, proficiency drops to 30 percent. Cornerstone was founded to close that gap because every child deserves the right to read.

Our Goals

• Open Fall 2026 with Grades K–3
• Add Grades 4–5 by 2028 and reach full K–8 capacity by 2031
• Establish a regional literacy hub to share best practices and training.
