Berkeley International School Bangkok (Berkeley)

The school operates with 55 teaching staff members delivering American curriculum standards to its diverse student body of over 32 nationalities. With more than 60% Western students, Berkeley creates an environment where students develop cross-cultural skills while preparing for studies abroad. English serves as the medium of instruction throughout the school, supporting the development of authentic language skills in speaking, listening, reading, and writing.

Berkeley's Bangna campus features significant athletic and wellness infrastructure, including a 10-lane Olympic-sized swimming pool, indoor tennis court, football field, and a modern air-conditioned gymnasium housing basketball, badminton, and table tennis courts. The school has also made heavy investments in music and technology programs to support diverse learning approaches. WASC accreditation provides international recognition of the school's educational standards and quality assurance processes.

• Berkeley sits in the second tier of Bangkok internationals in parent and teacher discussion. One forum poster said it "isn't top tier so might be a good start". Another, from a teacher angle, called it "the type of place you do not want to work".
• Older teacher-forum threads were sharper, calling Berkeley "a lower-tier international school" and warning that the school had once "not been requiring teaching certification". Those posts are dated and predate current leadership but remain easy to find.
• A more recent teacher review describes Berkeley as one option in the Bangkok mid-market, in the same bracket as Aster, Garden and ICS, with fees around 665,000 baht plus first-year fees.
• Staff reviews on aggregator sites give a 3.6 picture: friendly colleagues and work-life balance, but weaker scores for senior management and career progression. A common con is "teachers barely get a raise year to year".
• Parent-facing reviews on advisory directories are positive. Parents praise small class sizes, the campus and the Bangna location with BTS shuttle access. There are no parent reviews on the main international schools directory.
