Meet our talented Secondary Years teachers.

We read over 250 applications each year before carefully selecting candidates for any new teaching positions. All teachers receive 2 weeks of rigorous training before they start and benefit from around 70 hours of ongoing professional development support throughout the school year.

Teachers must be qualified and experienced, but most of all they must be ready to be role models to our students. We know we ultimately teach through modelling and expect all teachers to fully embrace the values of the school and develop personal attributes in line with the school’s 12 Wise Habits.

At Panyaden, we value passion, personality, commitment.
