At Harker’s preschool we emphasize hands-on learning, intentional play and developmentally appropriate classroom activities.


Admission Announcement: We are phasing out our preschool program to make room for the move of our middle school to the Union Avenue campus in fall 2021. For the 2020-21 school year we are only accepting applications for our Transitional Kindergarten program. There will be no 4-year-old program in the 2020-21 school year.

Beginnings matter.

At Harker, we understand the importance of giving your children the best possible foundation for an outstanding academic career. That starts with choosing the right early education environment to excite, nurture and challenge children so they are not only ready for the next step but excited to get there.


Why Choose Harker Preschool?

At Harker you will find an innovative and immersive experience unlike any other program. We combine top teaching talent with a blend of the best practices from a variety of philosophies and pedagogies, both project-based and play-based.

Our formula is unique because we layer everything with an approach that is quintessentially Harker: the ability to ignite in children of all ages a fervent love of learning that sets them apart. How do we do it? Learn more about preschool academics.

A Harker Early Education That Inspires

Teaching early learners is the passion and expertise of our talented teaching team. Our beautiful and expansive campus, located in San Jose, is the perfect setting to encourage young children to explore, discover, create and connect.

Children view our school as a place where their imaginations come alive, complete with cottage classrooms and a working farm. What they don’t realize is that every activity and prop is an intentional part of their environment, developed by their teachers to enhance key skills that set them up for success in kindergarten, lower school and beyond.

At Harker, your child will benefit from a comprehensive and resource-rich program; read about our program elements below.
