Londonderry was founded in 1971 and has been changing and growing in response to the parents' and teachers' continued quest for the best possible education for young children. Londonderry's elementary program is licensed by the Pennsylvania Board of Private Academic Schools and the preschool and kindergarten program is one of the few early childhood programs in Central Pennsylvania accredited by the National Academy of Early Childhood Programs (NAEYC). Throughout the years Londonderry has maintained its original principals.

The Londonderry School offers a preschool through elementary school program emphasizing the development of the whole child. The areas of social, emotional, cognitive, creative, and physical development are all considered important aspects of Londonderry's integrated and enriching school curriculum. Primary emphasis is given to the development of the child's feelings of self-esteem as the necessary foundation for successful learning and social interactions.

To enact the philosophy, Londonderry adheres to the following principles:

• That the development of a curiosity and excitement about learning is as important as the acquisition of a set of skills or factual knowledge.
• That the intent of learning in a subject area is to impart the ability to generalize the knowledge gained, ask key questions, think critically, and problem solve.
• That children learn best when they are actively involved in the learning process. Children must have ample opportunities to manipulate their environment and interact with their teacher and peers.
• That children learn best when the content of the curriculum is meaningful to them. Children must have opportunities to pursue their interests and relate learning to personal experiences. Teachers are encouraged to design a flexible curriculum with the children's interests and abilities in mind.
• That the school curriculum should integrate subject areas in a natural way and include opportunities for involvement in activities such as art, music, physical education and outdoor play, cooking, and computers on a regular basis.
• That the interaction of children of different age levels has a positive effect on all children and promotes a family-like atmosphere. Flexible age groupings are a purposeful part of the Londonderry desire to allow for the natural development of skills and abilities in an unpressured atmosphere which fosters a positive self-image.
• That children learn best when they are allowed to progress through the curriculum at an individualized rate and receive the extra attention needed to challenge or nurture their abilities and receive special help as needed.
• That respect for children as individuals and respect for teachers' abilities to use their own individual skills, resources, and interests fosters a positive and mutually rewarding teaching environment.
• That parental involvement is key to the success of Londonderry in meeting the needs of students and in receiving direction for the school's future.
