Annual Open House
Families interested in Seton are strongly encouraged to attend our Open House for parents and prospective students. The Open House provides an excellent opportunity to learn about the philosophy and academic standards of Seton School. Following the formal presentation, visitors will meet our faculty, tour the school, talk with current students, and attend “mini-classes” in several subject areas. Both buildings will also be available for tours. Additionally, you may also learn more about Seton School by watching welcome videos from our founder, Mrs. Anne W. Carroll, our Department Chairs, and some of Seton’s integral volunteers.
Next Open House:
TBA
Formal Presentation begins at 2 P.M. in the gymnasium located in the main building. Mini classes and a reception will follow in the Corpus Christi building.

Financial Aid
For Financial Aid consideration, families of accepted students must complete a financial aid application and provide requested financial documentation to FACTS Grant & Aid Assessment. FACTS, an independent third party, assesses a family’s financial situation and recommends to Seton School the level of aid a family requires. The Seton administration exclusively makes final determination of all awarded aid. Seton’s financial assistance comes through a work program. Families receiving reduced tuition must work in various capacities to contribute to the betterment of Seton School. If the assigned work is not completed, then tuition will be assessed. For additional information about FACTS, please refer to: https://factsmgt.com/parent-faqs/.
Seton School does not discriminate in its admissions or in any of its programs on the basis of race, color, or national origin.
