About ONE FIFTY PARKER STREET SCHOOL (operating as One Fifty Parker Avenue School)
One Fifty Parker Avenue School is an independent, parent-governed nonprofit early childhood program in San Francisco’s Laurel Heights that operates a small, play-based preschool and transitional kindergarten. The program emphasizes social-emotional development, emergent hands-on curriculum, low student–teacher ratios, and weekly music and documentation of children’s learning. Founded in 1954 and incorporated as a nonprofit in 1969, the school serves a small cohort (roughly 44–48 children annually) and maintains active family engagement through a DEI committee, weekly parent communications and a regular blog for the school community. Parker School participates in San Francisco’s Early Learning for All program and maintains an internal tuition-assistance program to expand access for qualifying families.
