A Private School Education at a Public School Price


21st Century is a charter school currently serving grades 4-8, that has been in place in Albuquerque, New Mexico since 2000. We serve a diverse population of over 80 students per grade. All staff bring years of teaching experience into our classrooms and many have worked together in other settings.


At 21st Century, coordination and collaboration among teachers and staff is central to our educational philosophy.  Teachers meet in grade level teams every day to coordinate with one another and to prepare collaborative lessons. Departments meet every week to chart progress and address needs within their subject area.
