Teacher of Mathematics

Full-time
MPS/UPS

Inspire the next generation of Mathematicians at the school where it all began with Newton.

The King's School, Grantham, is seeking a Teacher of Mathematics to join our thriving Mathematics department.

Founded in 1528, King's is a selective Grammar School with a proud tradition of academic excellence. Sir Isaac Newton is our most famous alumnus, but every great scientist has a story, and it is historians who tell it. At King's, Mathematics is a subject that matters.

The Mathematics department at King’s is one where students genuinely engage. Half of all students choose to study Mathematics at A level each year, and our students consistently achieve exceptional results. They are motivated, intellectually curious and relish the kind of analytical challenge that Mathematics demands. For a Mathematics teacher, that is a rare and rewarding combination.

We welcome applications from both experienced practitioners and early career teachers. What matters most is a genuine passion for Mathematics and the ability to bring the subject to life in the classroom. Whether you are an accomplished teacher looking for a department that matches your ambition, or someone at the start of your career seeking an environment where you will be properly supported and developed, this role offers a real opportunity to grow.
