School History

  • 2002

    Bromsgrove International School was founded in 2002 under the name of Windsor International School and owned by Windsor Education Co. Ltd. The first phase of construction was at Soi 164 Ramkhamheang Road, Minburi, in Eastern Bangkok. A new building was opened in September 2004 to meet the demand from Early Years and Primary students wishing to enrol at the school.

    In 2004 Oriental Siam (1978) Co. Ltd became the majority shareholder and also provided the financial support to enable the school to become one of the top international schools in Thailand. In April 2004 the School became affiliated to the prestigious Bromsgrove School UK and changed its name to Bromsgrove International School Thailand (BIST). Bromsgrove School UK was founded over 500 years ago and is a leading co-educational independent day and boarding school.

    In the same year the building of the new prestigious Primary and Secondary campus at Windsor Park Golf Club commenced. The Ramkhamheang Campus was then converted to an Early Years campus for children aged 2 to 7.

    Over the next two years, pupil numbers increased rapidly resulting in the launching of the BIST Boarding Programme. Also during this year, another milestone in the school’s history was reached when it became an accredited University of Cambridge (CIE) examination centre. Throughout this year the school’s reputation for outstanding academic and sporting achievements continued to grow.  Our students also competed against the top international schools in Bangkok, winning many fixtures and competitions.

    Also this year the school also became an overseas full member of the Boarding Schools Association (BSA) in the UK, which ensured our boarding standards were benchmarked to those of our sister school, Bromsgrove School, UK.

During the CIS accreditation visit the visiting team commented that the school had many outstanding features, including world-class boarding facilities.

    The school continued to grow in both student numbers, academic success and its regional reputation for excellence. Our largest ever graduating Year 13 A-Level class achieved some outstanding external examination results and were accepted into some of the very best universities and colleges throughout the world.
