City International School

City International School was established in 2008 with an initial intake of about 50 students and a capacity of more than 800. The founder, Late Syed Humayun Muzaffar (1950-2015), laid the foundation of City International School in 2008 to create a centre of excellence serving students from diverse socio-economic and cultural backgrounds. In 2009 the school strengthened its international outlook by introducing the IGCSE and AS/A level courses to provide access to universities worldwide. The school is governed by the Humayun family, with Qamar-Un-Nisa Humayun listed as Founder and Chairperson on the Board of Directors. The school's aims emphasize balanced, high quality education and the development of ethical and humanistic standards within Bahrain's diverse community.

City International School hosts community events that bring families and staff together. The annual graduation ceremony is a prominent event, with the 2017 graduation at Crowne Plaza Hotel drawing dignitaries and ambassadors to celebrate more than 200 graduates from KG, Grade 6 and Grade 10. Public communications memorialize the founder's legacy with a Floral Tribute and reflections from the school community. The school emphasizes an international and diverse student body and offers extensive extracurricular activities to support well-being and holistic development.

Public materials describe governance by founders and a Board of Directors rather than a separate PTA. Late Syed Humayun Muzaffar founded City International School in 2008; he lived 1950-2015. Qamar-Un-Nisa Humayun is listed as Founder and Chairperson on the Board of Directors. The school has publicly documented major family-involved events, such as graduation ceremonies with notable guests. A Floral Tribute to the founding father is featured on the site, reflecting the community's memory and continuity of leadership. The school emphasizes an international, values-driven education and ongoing community involvement.
