JOANNA SUN-Director of Language Lab​​

​Joanna Sun​​

As a product of both the British education system (including IB), culminating in graduation from the University of Oxford, and a Shanghai international school following the AP curriculum, she is deeply familiar with international curricula and pathways. More importantly, she represents the educational outcome that many international school parents aspire for their children to achieve.​

Born to a mother with a doctorate, she feels that education “chose” her just as much as she chose it. Her relationship—or even yuanfen (缘分)—with English teaching began during her IB years, when she taught ESL to immigrant children with no prior English knowledge as part of the IB CAS programme. Through dedication and hard work, the student she taught made such remarkable progress that both teacher and student were interviewed by BBC News at the time.​

To date, she has accumulated 15 years of experience in ESL teaching, 10 years in international education and university counselling, and almost 8 years in education management, curriculum design, and implementation.​

She is currently the Co-founder and Deputy Head of a small school of approximately 100 students in her parents’ hometown of Liyang, which she co-founded in 2018. The school is the only institution in the city legally licensed to teach English and employ foreign teachers. Its students are widely recognised for possessing the strongest and most natural English proficiency in the city, with learners ranging from Early Years to IELTS candidates and adult learners.​
