Big-District Advantage: Finding Your Home in D300

Algonquin Community Unit School District 300 is one of the largest school districts in Illinois — and with scale comes serious resources. Serving roughly 18,000 students across Kane and McHenry counties, D300 encompasses Algonquin, Carpentersville, East and West Dundee, Gilberts, Sleepy Hollow, and portions of Pingree Grove, giving families a broad range of communities to choose from while staying within the same district umbrella.

The district operates two comprehensive high schools: Jacobs High School in Algonquin and Dundee-Crown High School in Carpentersville. Both schools offer robust AP and honors programming, competitive athletics, and extensive extracurricular options. Career and technical education pathways in healthcare, engineering, digital arts, and business give students real-world skills before graduation — a meaningful differentiator in today’s college and job market.

At the elementary and middle school levels, D300 emphasizes differentiated instruction, STEM integration, and social-emotional learning to ensure every student builds a strong foundation before reaching high school. Dedicated programs for English language learners and students with diverse needs reflect the district’s commitment to serving one of the region’s most diverse student populations.

For homebuyers, choosing a D300 address means access to a well-funded public system with the breadth of programs typically associated with much larger urban districts — but with the community feel of Northern Illinois suburbs. Whether you’re drawn to the Fox River character of Algonquin or the convenient location of Carpentersville, your children will share the same strong educational foundation.
