I have over 25 years’ experience in education. Prior to re-joining 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 Chair 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.

Christopher Hayward

High School Principal, MYP Coordinator (G9-10), Mathematics Teacher

Bachelor Of Science (Applied Mathematics)
Professional Graduate Diploma in Education (Secondary)

Having grown up in an international school and having always enjoyed mathematics, sharing my passion for the subject with others lead me to teaching. I completed an undergraduate degree in Applied Mathematics and subsequently teacher training and then enjoyed a range of experiences teaching in Scotland. The international pull grew stronger and I moved with my wife to Brunei. During an enriching eight years there I became Head of Department and subsequently Assistant Head, gaining experience with the IBDP Programme.

Moving on as a family of four, the opportunities of a vibrant city and new challenges brought us to Singapore and the ISS community became our home.

Working closely with students and seeing them grow through their school life and learning from their experiences gives me enormous pleasure. I strive to see students leaving school as strong individuals confident in their own abilities and able to work collaboratively with others.

Bachelor of Education
Diploma in Mathematical Education

I moved to Hong Kong from the United Kingdom as a young teacher in the 1980’s. Since then my career has taken me to many countries across the globe. I have held senior leadership positions in International Schools in Hong Kong, the Bahamas and most recently South Korea.

My philosophy of education and of life is exemplified by an open-minded, balanced and caring approach where human relationships and clarity of communication are of the utmost importance.

At the centre of everything is always the learner, student safety and well-being, as we continuously partner together to develop confident, skillful, knowledgeable, compassionate young people who will truly make a difference in the world.

In my leisure time, I enjoy a round of golf, swimming and choral singing.

Fiona Edwards

High School Assistant Principal, HSD & EAL Coordinator

Bachelor of Education (English, Bahasa Indonesia)

From a young age I lived in Indonesia and Brunei and experienced Singapore’s urban jungle in my teens. I finished high school and university in Perth, and at first found it difficult to reconcile my new Australian identity. My connection to Asia and my exposure to expat life made a Bachelor of Education in English and Bahasa Indonesia from Curtin University a natural choice. After 8 successful and fulfilling years teaching Bahasa at Perth College, an Anglican girl’s school, it was time for a change of scenery again to feed my travel bug! I spent the next 18 months travelling Asia and Europe, and living and teaching in the UK.

My next and current adventure took me back to South East Asia and ISS International School. It has been wonderful reminiscing about old school days with current students. Being able to give back to and be part of an international school community again has been extremely rewarding!

Born in Malaysia and brought up in Australia since the age of 4 by Sri Lankan parents, I have been grateful for the experiences I have had as a third culture child. After completing my PhD in Biomedical Sciences, I got married and decided to pursue an international teaching career. I have enjoyed teaching and leadership positions in public, private and international schools across Australia, UK and Singapore. ISS is truly a family community; one which my own family thrive and grow in everyday. I actively try to educate to make a difference, and I look forward to working with our wonderful community as Assistant Principal of Middle School.

Christopher Garden

IBDP Coordinator, TOK Coordinator and Music Teacher

Bachelor Of Music
Graduate Diploma of Education (Secondary Music)
Master Of Theology

I am a passionate IB leader, educator and musician with vast experience in international and Australian schools, specialising in Music, Theory of Knowledge and Religious Education. A passionate musician with extensive experience leading ensembles, my leadership philosophy stems from a desire to achieve excellence through team building. My core motivation is seeing improved teaching and learning for all students through developing meaningful collaborative cultures within school settings.  A strong belief in constructivist and inquiry-based learning leads me to be an advocate for the IB frameworks, with experience in both the Diploma and Middle Years Programmes. Leading students and teachers into the unknown world of the 21st Century through developing core ‘soft skills’ and positive psychology is certainly an exciting venture.
