McHenry County’s Premier K–12: Crystal Lake Districts 47 & 155

Crystal Lake is one of the few McHenry County communities where two separate, highly regarded districts — Elementary District 47 (K–8) and Community High School District 155 (9–12) — work in close coordination to deliver a seamless K–12 experience. The result is a public school system that consistently ranks among the strongest in the region for academic achievement, extracurricular breadth, and student outcomes.

D47 operates nine elementary schools and two junior high schools, giving families granular choices within the same district. Schools like Hannah Beardsley and Richard Miller junior highs provide dedicated 7th and 8th grade environments focused on academic preparation and character development — a bridge that sets Crystal Lake students up for success the moment they enter one of D155’s three comprehensive high schools.

At the high school level, D155’s trio of schools — Crystal Lake Central, Crystal Lake South, and Prairie Ridge — each offer a full slate of AP courses, honors programming, competitive athletics, and performing arts. Prairie Ridge, in particular, has earned recognition as one of Illinois’s top public high schools and consistently produces strong college-bound graduates. The choice of which high school a student attends is determined by their attendance zone, but all three deliver the same rigorous curriculum and extracurricular opportunities.

Beyond academics, Crystal Lake itself is a selling point: a genuine downtown with restaurants, boutiques, and a Metra commuter rail station, plus the namesake lake offering swimming beaches, boating, and an unmistakable character that makes this community feel like a destination, not just a suburb. For families prioritizing both school quality and quality of life, Crystal Lake checks every box.
