On the morning of September 1, 1964, 200 children (grades 1-6), four Sisters of Mercy from Galway City, Ireland, one lay teacher, the pastor and friends participated in a ceremony in a warehouse at Merritt Island Airport that began the dream of Divine Mercy School.

• In February 1965, the ground was broken for a permanent school building that was ready for the first day of school in September 1965. Two more Sisters had come from Ireland and a kindergarten class was added.
• During the summer of 1967, a building from Patrick Air Force Base was purchased, assembled, and proudly named Hartnett Hall. We now had kindergarten through eighth grade.
• The 1986-87 school year saw the addition of a pre-kindergarten class and an extended day program.
• The silver jubilee of 1989 began with the addition of a beautiful new wing to the school, adding a fully furnished science lab, a computer lab, and a teacher’s lounge.
• The thirtieth anniversary (1964-1994) was celebrated with another school extension, Mercy Center, which added four additional classrooms and three flexible meeting areas for parish functions.

In the year 2000, the flexible meeting areas were renovated and converted into a state of the art library/media center with an accompanying media production studio. True to the pioneer spirit of Merritt Island’s early Catholic Community, Divine Mercy has always labored diligently with limited resources to achieve excellence in education.

In 2001- 2002 Divine Mercy replaced the old playground equipment with new, enlarged and refurbished the computer lab, added a full science lab, security system and set up a second computer lab in the library/media center.

The school community developed a strategic plan, and the parish undertook a capital campaign for the refurbishment of the Church and School facilities during the 2002 - 2003 school year.

The 40th Anniversary Year of the School (2004-2005) was a very significant year. Divine Mercy School was officially recognized by the U. S. Department of Education as a Blue Ribbon School.

It is through that spirit that the school continues to be the hub of educational activity, with lifelong learning programs continuing to meet the needs of the individual and family as it boldly enters a new phase of growth into the new millennium.
