The city of Belvidere is a cozy suburban community positioned on the east side of Rockford. The city is widely known for its State Street Historic District, which spans both banks of the Kishwaukee River. This part of town is packed with beautiful red brick buildings and vintage storefronts still in active use today, hosting a vast selection of popular cafes, boutique shops, and other locally-owned businesses. Known as “Illinois’ City of Murals,” Belvidere proudly displays countless public works of art all across the community, including numerous old-time hand-painted advertisements. A string of large nature preserves lining the riverbanks provides endless opportunities for spending quality time outdoors, and Magic Waters Waterpark just west of town makes a perfect destination for hot summer days.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
