About St. Charles Community Unit School District 303
St. Charles Community Unit School District 303 assigns each address separately at the elementary, middle, and high-school levels before students reach St. Charles East or St. Charles North. The maps approved for 2024–25 remain the current operating baseline, so older feeder lists can be wrong even when the school names have not changed.
The interactive result is still subject to an explicit administrative condition: the district may adjust a placement when overcrowding or other district needs require it. That authority makes the locator a current starting point rather than an unconditional promise detached from enrollment conditions.
Compass Academy and the Transition Program use student-specific district processes. They add alternative and post-high-school settings to a system whose ordinary route is still determined by the three current attendance maps.
