"We have used GSL for many years for long term and day-to-day supply staff for both teaching and support workforce. We found the agency reliable and effective. The agency consultants respond professionally to our needs and they follow the appropriate procedures for safeguarding and forwarding documents and materials. We are very pleased with the work of GSL and happy to continue to grow our relationship as they have the knowledge of the local area and know our exact requirement which they always fulfil".

- Abdulla Fathulla, Assistant Director, Bishop Challoner Catholic Collegiate School

"GSL offers a most reliable service, provided by conscientious people. Their commitment to recruiting and placing high quality teachers in my school has made my job so much easier. After four years of dealing with them, I can say that I am guaranteed the best whenever I call on them to assist."

- Paul Jones, Mulberry School for Girls

"I have always found the service to be quick and efficient. The quality of supply staff that we receive has been excellent and have many repeat bookings. The follow up paperwork is always received on the same day and on the rare occasion of any problems arising these are dealt with promptly. I now feel I can trust GSL in supplying the right calibre of teacher for our school."

- Kay, Harris Academy at Peckham

"One of the big advantages in using GSL is the continuity of staff. They are friendly and highly efficient but not pushy. The rates charged by the company are very competitive and they have a wide range of teachers and cover supervisors on their books. We have enjoyed some excellent placements from GSL."

- Michael Fargan, St Thomas More

"The consultants are always pleasant, helpful and as accommodating as possible. The vetting sheets are sent before arrival so we know who to expect and the person always has ID with them. I feel confident using GSL for both the daily and long term needs of the school."

- Linda Horan, Office Manager, Eastlea Community School

"I have long term supply teachers covering a range of subjects and get on well with GSL teachers. They have always been on time, are always smartly dressed and ready to work. GSL speak to me on a regular basis and never push for wrong teachers to get placements. Their teachers can handle behaviour situations themselves, instead of frequent calls to Emergency Support. In a busy community school such as ours, we have to deal with agencies that can be relied upon and can handle short notice calls. GSL have been able to do this. There are only a very few times I have had to use another agency and this is a testament to their value. I recommend GSL to any school."

- Steve Walls, Cover Manager, Stoke Newington School
