"GSL are an excellent agency to work for. They combine the right balance of professionalism and friendliness. I have always had good information about the schools I am going to, and they have dealt with any situations with the school really quickly. When I had to take an emergency day off due to a sick child, they were very supportive and helpful. I would have no qualms about wholeheartedly recommending them to any teacher looking for supply work."

They have always made me feel like a worthwhile employee and therefore I recommend GSL Education to any teacher looking for daily, short term and long term assignment in London to contact them. If you need a good honest agency that doesn’t rip you off or treat you as a number, then join GSL Education and you will not be disappointed."

"Even before finishing my PGCE I registered with GSL and as soon as I completed my qualification I started working in a good variety of schools and that led me to improve my behaviour management skills. In my experience the staff from GSL are enthusiastically received in schools and that makes a difference in feeling yourself valued as a supply teacher. Abreast to professionalism you will find supportiveness and friendliness, I would not hesitate to recommend GSL to all newly qualified teachers as well as to experienced ones."
