Every year, NDHS students attend a required class retreat. Retreat provides a great environment for the class to bond and grow in faith together. Freshmen attend a one day retreat to learn about and reflect on the charism of the School Sisters of Notre Dame. Sophomores participate in a day-long retreat on campus. Junior retreat is an overnight retreat focusing on their faith journey and their hopes for the future. Seniors participate in the three-day Kairos Retreat Program.
