Welcome to Immaculate High School

Immaculate High School

Thank you for exploring Immaculate High School! As an A rated school and the #1 Catholic, co-ed, day school in Connecticut (Niche 2023), our mission and outcomes have never been stronger. We are currently accepting applications for Grades 9-11 on a rolling basis for 2023-2024 and welcome you to visit us for a personal tour.

Immaculate is a college preparatory school and outcomes matter. Our AP and dual enrollment offerings, along with an innovative curriculum will set your child up for success at every turn. The Class of 2022 achieved a 100% acceptance rate into 243 colleges and universities and were awarded a record $33.5M+ in scholarships and awards. We encourage you to compare those results with private schools that charge significantly higher tuitions. Immaculate continues to raise the bar for our students, providing them with the tools, care and personalized attention to meet their goals. The values modeled and taught throughout their four years at Immaculate will undoubtedly lead our newest graduates to lives marked by passion and purpose, along with treasured memories and enduring friendships.

As an alumna, I look forward to welcoming you to a school community that is steeped in tradition and Mustang pride, rooted in faith and compassion, and committed to every student reaching his or her full potential. Respect, Responsibility and Reverence is our motto and is witnessed when you walk the halls of our school. Welcome to Immaculate High School's admissions experience. We can't wait to meet you!
