Dr. Margaret Alvarez

Head Emeritus

I have over 25 years’ experience in education. Prior to rejoining ISS International School, I served as the Associate Director of Accreditation for the Council of International Schools (CIS). In this role, I have evaluated international schools in Europe, Asia and the Middle East, and was responsible for overseeing international school evaluations in Asia (including Singapore). My other responsibilities included research and development, teacher training, and government relations. I have published various papers on school improvement, the development of global citizenship skills and effective administration. I am an IB trainer and am also the Past President of the Board of Trustees of the East Asia Regional Council of Schools (EARCOS); the Council that supports international schools in our area.

I was part of the team that designed the CIS protocol used to measure the quality of international schools and was responsible for designing the protocol CIS uses during joint evaluations with the International Baccalaureate (IB).

Before joining CIS, I served ISS International School for thirteen years in various roles including Head of World Languages, Head of High School and Head of School. During this time, I introduced the three IB programmes (IBPYP, IBMYP and IBDP) to the school. I started my career as a French and German teacher within government schools in the United Kingdom then moved to Europe where I taught English as an Additional Language, French, German and Spanish in European International Schools.

My educational philosophy places student learning and wellbeing at the heart of everything a school undertakes. The leadership model I have designed is informed by my observations, research and many years of experience as a school leader and evaluator.

I am married to Antonio and have two daughters who are both ISS graduates.
