How admission works

Cornerstone Charter Academy takes applications directly. North Carolina law requires a charter school to hold a lottery when more students apply than it has room for.

Charter schools are free and open to any North Carolina child, but they do not have to provide school buses or meals the way the district does; ask the school what it offers. Our Guilford County Schools zone guide covers the district schools near each address.

Calendar

Cornerstone Charter Academy sets its own calendar, separate from Guilford County Schools’. The website the state lists for the school, www.cornerstone.teamcfa.org, did not load when we checked on Oct. 11, so call the school at 336-482-3855 for break dates and enrollment details.
