At One Fifty Parker Avenue School, we offer a small, homelike setting where children can explore freely, spread their wings, and discover who they are and what it means to be a part of a larger community.

We believe children learn best and make sense of the world around them when given time to play. Our teachers are skilled play facilitators, guiding children through their social interactions and peer relationships to help build their confidence, language skills, and empathy. Our curriculum is grounded in social-emotional development and by the end of their time at Parker School, children have learned how to express themselves, their ideas, and their feelings. With gentle guidance, each child builds their ability to emotionally self-regulate in our safe and nurturing classrooms.

Teachers offer thoughtful amounts of structure to each classroom and provide plenty of opportunities for inquiry and hands-on learning. Our emergent, developmentally-appropriate curriculum stems from the children’s interests. Projects and activities have the flexibility to take new shape as teachers become learners alongside the children. Through these projects, children ask questions and express themselves through language, art, dance, writing, dramatic play, and building. They problem-solve, test theories, and learn to persevere.

Our Music Specialist spends time each week in every program, providing a wide range of traditional, novel, and fun music experiences to the children. Our On-Call Occupational Therapist observes social interactions at different points through the year and consults with teachers so that each child can be actively and appropriately engaged at school. Our OT also helps teachers plan activities and strategies that will support each child’s unique sensory, gross motor, and fine motor needs in order to build their self-regulation.

We make our children’s learning visible through careful observation, reflection and documentation. Teachers have weekly team meetings to collaborate and plan curriculum that supports both individual and group needs. Teachers compile photos, quotes, and anecdotes that illustrate what each classroom is currently exploring and we share this documentation with parents through our display boards and our weekly newsletter, the What’s Happening.

We are committed to creating a safe, nurturing school that reflects the diversity of our broader community in San Francisco. We are an inclusive school and are proud to have recently become a part of San Francisco’s Preschool for All Program. This funding means we can offer a significantly reduced tuition to qualifying families. 


A little history. 

Dorothy Rothkop founded One Fifty Parker Avenue School in 1954. In 1969 a group of energetic and enthusiastic parents purchased the school and expanded the program to include two nursery school sessions, a kindergarten and an extended childcare program. It was incorporated as a nonprofit the same year.

One Fifty Parker Avenue School is an independent nonprofit corporation governed by a Board of Directors made up of parents, alumni parents, and the director of the school. 

These dedicated members serve as legal officers and maintain the integrity, philosophical, administrative and financial aspects of the school. We welcome our family members as active partners at school, and parents participate in a variety of ways including fundraising, special school projects and social events. Educational decisions are solely the responsibility of the Director and Teaching staff. The relationship between staff, parents and children is most important to the well being of our school. Appropriate, open communication is the key!

The Basics:

One Fifty Parker Avenue School serves children ages 2.5 to 6 years of age. Children are placed into classes by age: 2.5-3.5 year-olds join our AM Nursery class in September. 3.5-4.5 year-olds move into our PM Nursery class their second September with us. Our Transitional Kindergarten class is a third year for children 4.5-5 years old who are typically not age eligible to enter Kindergarten after two years at Parker School.

Our AM & PM Nursery classes are made up of 24 children and 4 teachers. Our TK class is made up of 12 children and 2 teachers. We keep a 6::1 ratio in all classes.

Our AM & PM Nursery programs are in session 3 hours per day, 5 days a week. Our TK class is in session 4.25 hours a day 5 days a week.

In addition to the core programs, childcare options are available daily for either a couple of additional hours or as much as 7.5 additional hours daily. (school is open 7:30-6)

There is a core program schedule switch from the AM Nursery year to the PM Nursery year. 9am-12pm are the daily hours for AM Nursery. 1pm-4pm are the daily hours for PM Nursery.

Typically parents make all childcare commitments at the beginning of the year and hold that routine through the year.
