Welcome to Immaculate High School

Immaculate High School

Thank you for exploring Immaculate High School! As an A+ rated school (Niche 2024), Immaculate represents the top 2.5% of high schools in the country! Our consistent ranking as the #1 Catholic, Co-Ed Day School in CT is a testament to the fact that Immaculate's mission and outcomes have never been stronger.

We are currently accepting applications on a rolling basis for 2024-2025 admission, with limited spots available. Applications for the Class of 2029 (Fall 2025) opened on July 1.

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 2024 achieved a 100% college acceptance rate and were awarded over $28M in scholarships and awards. We encourage families 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 lead our graduates to lives marked by passion and purpose, along with treasured memories and enduring friendships.

Immaculate is an incredibly diverse community with students hailing from approximately 25 different towns. It is noteworthy that local Westchester County, NY school districts within a 15 miles radius provide free transportation to our school here in Danbury.

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!
