Pacific Rim International School (PRINTS) opened its doors 25 years ago as one of the first Mandarin/English bilingual Montessori schools in 1989 at the Julia Morgan Center in Berkeley, California, with six children enrolled in the Children's House.

In 1991, eight children from the Children's House became the first students of a new Elementary Community. Enrollment continued to grow, and with it, the school expanded.

In 1993, PRINTS began building new Montessori environments in a remodeled warehouse in Emeryville. These environments were specifically designed to be optimal Montessori learning spaces. This building continues to serve as PRINTS' East Bay campus to this day.

In 1995, PRINTS launched its Japanese/English bilingual program.

By 1996, PRINTS further expanded with an Infant Community, a Children's House and an Elementary Community serving children from the age of eighteen months to twelve years.

In September 1997, PRINTS founded a second campus in San Mateo (the Japanese Program is currently only available on this campus).

In 2005, PRINTS inaugurated an Upper School, consisting of a Montessori Middle School or Erdkinder (German for 'earth children') Community and High School program at the San Mateo campus. The High School gained the International Baccalaureate Accreditation in 2009.

2013 saw the foundation of Hands-on-Prints, a publishing press dedicated to creating children's books that are imaginative extensions of the Montessori curriculum. With poetry, prose, fiction and non-fiction, reading levels from the youngest to the high-school, its aim is to take the Montessori vision to a new literacy level.

In 2014, PRINTS inaugurated its Nido program, a center for infants that, like all other levels at PRINTS, features a dual-immersion Montessori environment. With this latest addition, the school can now offer children of all ages a nurturing place for developing fluency in several languages as well as foundational skills. Based on Montessori philosophy and informed by the latest findings in neuroscience, this environment gives children an optimal start by cultivating joy in learning and discovery.
