| The Essex-Caledonia Supervisory Union is comprised of 9 towns, four of which maintain schools. We are often referred to as "The Northeast Kingdom" due to our rural setting. The towns that we serve are Concord, Gilman, Granby, Guildhall, Kirby, Lunenburg, Maidstone, Waterford & Victory. Concord is our only district which maintains a PreK-Grade 12. Guildhall is PreK-Grade 6 while Lunenburg & Waterford are PrK-Grade 8.
