EBI was created by a group of committed parents and professional educators who envisioned an outstanding bilingual education program based on the best teaching and learning practices from around the world.

These pioneers valued the immense cognitive, social and cultural benefits of multilingualism and wanted to encourage children to be engaged members of both Spanish and English learning communities. They found that no Spanish-English independent school existed in the Bay Area, no Spanish-English bilingual programs extended beyond 5th grade and public school bilingual programs were limited in access and in the scope of their mission.

EBI’s founders were committed to creating a dual immersion school for students from pre-kinder through 8th grade that would prepare children at the highest level in all disciplines, in both Spanish and English.

EBI first opened its doors at the St. Augustine Parish in Oakland in September 2006, becoming the first independent co-educational day school offering a Spanish-English dual immersion program to pre-kinder and elementary students in the Bay Area. The Alcatraz Campus (St. Augustine Parish site) has served as a critical center for EBI's development and future growth. In 2011, EBI acquired the San Pablo Campus thanks to the generous support and collaboration of Steve Oliver and Co. The San Pablo Campus opened its doors in fall of 2011.

Also in 2011, the International Baccalaureate (IB) authorized EBI to offer the IB Primary Years Programme (PYP). 

IB World Schools share a common philosophy—a commitment to improve the teaching and learning of a diverse and inclusive community of students by delivering challenging, high quality programmes of international education that share a powerful vision.* 

In 2013, EBI opened six new classroom and auxiliary spaces at the San Pablo Campus. This was followed by seven more in the fall of 2014.

Also in 2014, the California Association of Independent Schools (CAIS) and the Western Association of Schools and Colleges (WASC) accredited EBI through 2021, the maximum accreditation period possible. EBI is authorized by the International Baccalaureate Organization (IBO) to offer the Primary Years Programme and has applied for authorization to implement the Middle years Programme (MYP).

In the summer of 2015, EBI celebrated another milestone, the graduation of the first eighth grade class. This year EBI also celebrated the tenth year anniversary of the school.

In 2016, EBI received the authorization from the IB to offer the Middle Years Programme (MYP), and it is now an IB World School.

*Mission Statement from the IB The International Baccalaureate aims to develop inquiring, knowledgeable and caring young people who help to create a better and more peaceful world through intercultural understanding and respect. To this end the organization works with schools, governments and international organizations to develop challenging programmes of international education and rigorous assessment. These programmes encourage students across the world to become active, compassionate and lifelong learners who understand that other people, with their differences, can also be right.
