Sarah Geraghty

Sarah Geraghty

English Specialist

From a young age, I always loved to read, appreciating literature’s ability to transport us back and forward in time, across oceans and plains, and into the shoes of others to see the world from diverse perspectives. It seemed natural to pursue this interest by studying a degree in English Language and Literature at The University of Oxford (St Hilda’s College). Upon graduating, I wanted to share my passion and expertise with students and decided to pursue a career in education.  

I completed my Post-Graduate Certificate in Education through Teach First, a programme that places graduates to train in socio-economically deprived areas of the United Kingdom. I spent three formative years working in Sheffield, and grew enormously as a teacher in this time, gaining experience teaching GCSE English Language and Literature. I also used my holidays and weekends to earn my Masters in Educational Leadership from the University of Manchester.

 Four years ago, I decided to pursue another life ambition of living and working overseas, and I moved to teach in Hong Kong. I worked at Sha Tin College, a school with a reputation for academic excellence that is ranked annually in the top ten schools in the world for average International Baccalaureate Diploma point score. During my time at STC, as well as teaching English, I have also lead the school-wide implementation of an innovative, concept-based curriculum for students aged 11-14 years, the Middle Years Programme.

Outside of work, I love to travel and explore, to cook, to spend time with family and friends, to visit museums and art galleries, and to keep fit through yoga and netball. Unsurprisingly though, you will most often find me curled up with a good book!

I am very excited to join the team at The British International School of Chicago, South Loop. The small class sizes will allow me to personalize my teaching for the students in my care, to offer more frequent and in depth feedback on their work, which I hope will enhance their academic progress and personal growth.
