A culture rooted in the values of East and West

Heads of Department



Sun Wei
Director of Administration
Executive Assistant to the Principal's Office

I started my teaching career with Beijing Huijia Private (IB) School since 1994 as a Manager, a homeroom teacher and a Chinese Teacher. After working there for 13 years I bring along my vast experiences and knowledge to HWA in 2006 where I joined the school as a Chinese Coordinator and Homeroom Teacher, ensuring a holistic and high standard quality of Chinese teaching and curriculum as well as a well-rounded Chinese cultural education.

As a pioneer staff of Hillside World Academy, I have seen HWA’s establishment from an infant foreign system school, grown to be an inspiring boutique international school with students coming from more than thirty nationalities, and fully qualified, experienced and dedicated teaching staff from all over the world. HWA is indeed a truly bi-cultural and bi-lingual school fully immersed with students, parents and teachers from diverse cultures. Being a small school has its unique strength where the community is closely knitted and strong support for each other is evident. As we continue to pursue HWA’s vision and mission, we proudly boast our strong school culture within the Eastern and Western values of Hillside World Academy.

He is an educator with more than 15 years of teaching and leadership experience. He has taken on leadership roles as Head of Department and Assistant Director in Singapore schools, the Singapore Ministry of Education (MOE), the Singapore Sports School and Republic Polytechnic (Singapore).

At the MOE, Leong Joo was the staff officer in charge of the establishment of Republic Polytechnic and the Yong Siew Toh Conservatory of Music at the National University of Singapore. He also worked on policy matters relating to the tertiary arts sector. As Assistant Director (Academics) at the Singapore Sports School, Leong Joo provided pedagogical leadership where he worked with and through the Heads of Departments and teachers on teaching and learning matters. He also contributed to the school’s professional development, strategic planning and quality assurance matters. As the International Baccalaureate Diploma Programme (IBDP) Coordinator, he played an instrumental role in the school’s authorization as an IB World School. The school’s first IBDP cohort of students took their examinations in November 2015 and achieved excellent results, averaging a score of 40 out of 45.

Prior to joining HWA in July 2016, Leong Joo was the Senior Lecturer at the Centre of Educational Development at Republic Polytechnic where he developed and provided training for the lecturers’ academic professional development.

Leong Joo believes that building well-integrated and high-performing teams here at HWA is important as we continue to ride on the uniqueness of HWA as a bicultural and bilingual IB international school, to enrich the learning experiences and strengthen academic rigour for all our students. 


Ms. Katty Zhao
Vice Principal, Admissions, Marketing and Communication

I have a few unforgettable memory on the stage of CNIS , and that is my pride to be one of the HWA family again.I never neglect an opportunity for my improvement in career.To reach the sales & marketing target would also become an exciting challenge for me in the future. 

I love kids! In my past career, I have been driven by my strong belief that every child should have access to a high quality education. It should be fun and challenging. We all believe that Education changes lives. Our “product” is only ‘completed’ at graduation and this makes education a very intangible product.Inspire and motivate our school team to contribute more and make our students’ learning experience in HWA rewarding and fun. 

Let’s works together to deliver our promise to provide excellent bilingual education for all lovely kids.That’s alI I want to achieve in HWA World Academy .
