For Kids‎ > ‎


Welcome!  We are happy to have you here.  Holliston Extended Day was founded in 1987 to serve the families of Holliston.  We are proud to be a program of the Holliston Public Schools

Who Are We?

Holliston Extended Day is an afterschool program serving the public schools of Holliston, Massachusetts. Our children range in age from pre-school through eighth grade. These age groups are divided into three programs. The first is YKO, which is our pre-school/kindergarten classroom. The second program is called OKO, and is home to children in grades 1-4. Finally, we have YMD, which is the program in serves students in grades 5-8. All programs share the same basic philosophy, yet each has it own, unique, age appropriate goals.

Mission Statement

Extended Day is dedicated to building each child's self esteem and to helping each child gain the social skills necessary for developing positive peer relationships and a positive self image.

All Extended Day activities are designed to reflect this philosophy. Extended Day activities will be process, not product oriented. Extended Day activities will challenge each child to explore, discover, create, and grow. Time to develop new interests is balanced with time to practice social skills while relaxing and playing with friends. To ensure that every student has a successful program experience, the teacher/student ratio is low and the teachers are experienced and caring.

Program Philosophy

The Holliston Extended Day Program strives to provide your child with an environment within which he/she can safely explore, discover, create, and grow. Children are supervised at all times while participating in program activities to ensure the health and safety of each child. The Extended Day staff recognizes the uniqueness and importance of each child and strives to create experiences wherein each child can learn to make choices, discover new pastimes, and explore new ideas in an environment that is safe, supportive, and creative. We are committed to doing our best to develop a safe and equitable program for all students.
