Kat Wagner 2021–22

Director of World Languages

I am a ‘third culture kid,’ who spends a lot of time thinking about words, languages, and learning. I'm always looking for unique ways to share my experiences with my students.

I joined BISW in 2010 and have been fortunate to work in a range of roles and contexts within the school.  As Director of World Languages, I am responsible for coordinating Languages provision across the whole school. I am extremely fortunate to work with a team of excellent Languages teachers at BISW, along with a group of highly-skilled external tutors. I also teach French and Theory of Knowledge, which affords me the opportunity to work with a wide range of inspiring and enthusiastic students across the Primary and Secondary phases of the school. 

Previously, I taught German and French at BISW, lead Languages in the Primary, and spent many years before that as a Primary school class teacher and school leader, both here and at a variety of different schools in London and Brighton in the UK. 
                                                                                                                                                                                                    I grew up in Luxembourg and attended a large international school, so BISW has always felt ‘like home’ for me. I hold a B.A. in Law with European Option from the University of Cambridge, and completed my PGCE, teacher training qualification, at the University of Nottingham. To further develop my subject knowledge, and as a result of my fascination with Languages and language learning, I am currently completing my M.A. in Applied Linguistics through the University of Massachusetts, Boston. 

Why do you love teaching?
Teaching is all about learning – for me and the students, and it’s always interesting and often unexpected. Each class and learner bring something different to their learning experience and, as a teacher, it’s a privilege to be part of that and to facilitate the journey. Language learning affords us the chance to engage with others and to shape and navigate our own linguistic and cultural identities, it’s a particularly fascinating and exciting process; one that constantly inspires and challenges me.
