Delbarton School is back— and better than ever. 

This fall, when this all boys (grades 7-12) Benedictine Catholic school’s 650 students return, the 187-acre campus will feature an updated science pavilion with a large STEM maker space; St. Benedict Hall, a library/guidance center that opened in April; and ongoing construction of a field house with modern amenities and spaces.

The school is also enhancing its curriculum, moving from trimesters to semesters, and adding more bus routes to encourage students from 3 states and 120 towns to participate in its co- and extra-curricular offerings. 

“We are blessed because our teachers are excellent, our facilities are superb, our learning environment is unparalleled—but the main draw of Delbarton is the culture of brotherhood beyond the classroom,” says Dean of Admission Dr. David Donovan. “Campus is bustling again…and this place feels better than ever.”

Nearly 1,500 Years of Lessons 

The Benedictine monks of St. Mary’s Abbey, a religious order founded in 529 BCE, opened Delbarton’s college-like campus in 1939. A recent survey showed satisfaction rates of Delbarton families and alumni higher than brands like Apple.

That’s due in part to a program that features 26 Advanced Placement courses, championship teams in 16 varsity sports and a dynamic Mission & Ministry program with 23 service initiatives.

The Delbarton Incubator course and a Business Center offering Bloomberg terminals broaden the School’s curriculum, and so do the 36,000 square foot Arts Center and robust global travel and exchange program.

During the pandemic, Delbarton was committed to teaching its students in-person, respecting all mandates, and fully intends to do the same this fall. 

But programs and protocols alone don’t make an exceptional school. 

Transforming boys into ethical, responsible and inquisitive young men does. The School also offers a strong alumni network to support its graduates.

Lending a Helping Hand

This year’s school theme is “Renewing traditions; renewing ourselves” and one of Donovan’s favorite traditions is financial aid outreach.

The school distributes $3.5 million in grants annually, averaging about $27,000.

By every measure, diversity matters at Delbarton.

“We have families from very different economic incomes who might not think they qualify, but are surprised that they do,” he says. “Cost should never be a reason not to apply.”
