The St. Aloysius Academy Co-ed Montessori Pre-school provides a supportive and caring environment where each child can grow spiritually, academically and socially. For children between the ages of 2 ½ to 5, the Pre-school is located on the St. Aloysius Academy campus in a building known as the Clockhouse.

The Clockhouse offers small class sizes lead by certified Montessori teachers. The curriculum includes daily religious instruction and is sponsored and staffed by the Sisters, Servants of the Immaculate Heart of Mary. Following the educational theory of Maria Montessori, children are grouped with mixed ages so they can interact and learn from one another.


Students learn language and math with attention to gross and fine motor skills taught using Montessori methods. There are many opportunities for parents to get involved, and supervised child care is offered until 6:00 p.m.

About Maria Montessori

Maria Montessori maintained that a more profound impression of life is gained through movement than by simply using visual or auditory aids. Voluntary repetition of movement is of the utmost importance for mental development. Children feel a sense of calm and repose in the Montessori atmosphere because everything has its proper place. Children are free to choose and complete a task on their own. Over a three-year period, teachers guide the children in the proper use of each set of learning materials, then leave them free to work and discover. The learning materials include practical life, sensorial, language and math skills.
