Mission Statement

Country Day School of the Holy Union, in the tradition of Catholic Education and the charism of the Holy Union Sisters, firmly believes that each person is created in the image and likeness of God, and thus the whole child is both celebrated and educated. A challenging curriculum strengthens students' academic skills and teaches them to think for themselves. Character is formed through age-appropriate responsibilities, and students are respected and taught to respect others, themselves, and creation. The school's community of wisdom and tradition of faith provide a supportive environment in which gifts and talents are recognized and nurtured.


Established in 1949, Country Day School of the Holy Union is a private, independent Catholic School serving students from pre-kindergarten through the eighth grade. Country Day School is under the sponsorship of the Holy Union Sisters. The order was founded in France in 1826 with a mission toward education. The school is situated on 16 acres of land located on Route 119 in Groton, Massachusetts.

After all the collections were in, the eighth grade class helped load everything into a pick- up truck (pictured here). The grand total was 1,022 lbs of food for Loaves and Fishes Food Pantry, which will help feed families in need in the communities of Ayer, Devens, Groton, Harvard, Littleton and Shirley.

Country Day School's Middle School Dance Supports Animals

On Friday, October 25th, Country Day School had their first middle school dance of the school year. While the admission fee typically goes toward the graduation celebration costs for the current 8th grade class, this year, the 13 and 14 year-olds wanted to make a difference. Together with their Math teacher, Mrs. Maguire, they decided to support the first grade community service project at Nevins Farm Adoption Center in Methuen. They agreed that anyone who brought in a pet food/supply donation to the dance would receive a discounted admission. Their efforts were rewarded with the donation of four large boxes of pet supplies for the service project of their first grade "buddies".
