Summary

Crystal Lake Central High School is a public high school serving 1,498 students in grades 9-12 in Crystal Lake, Illinois, which is part of the Community High School District 155. The school consistently ranks in the top 20-25% of Illinois high schools, with strong academic performance, high graduation rates, and generally solid results across student subgroups.

Crystal Lake Central High School's academic achievements are noteworthy, with 60.2% of 11th-grade students proficient or better in ACT English Language Arts, compared to the state average of 51.7%. The school's performance is particularly strong for White students and Special Education students, ranking in the top 20% and top 17% of Illinois high schools, respectively. However, the school's performance for English Language Learner (ELL) students and African American students is relatively lower, ranking in the bottom 50% and bottom 40% of Illinois high schools.

While Crystal Lake Central High School performs well compared to other high schools in the Community High School District 155, such as Cary-Grove Community High School and Crystal Lake South High School, its performance is not as strong as that of Prairie Ridge High School, another nearby school in the same district, which consistently ranks in the top 10-15% of Illinois high schools. Additionally, Crystal Lake Central High School has relatively high chronic absenteeism rates, which could be an area for further investigation and improvement.

Fantastic High School! It really made my oldest daughter ready for college and pushed her to take the most challenging classes that she could handle. Central encouraged her to get involved in activities at the school and to also volunteer in the community as well. I have another daughter who is currently attending and I wouldn't dream of ever changing her from this high school. Wonderful school spirit from the students, staff and parents at this school.
