The ISA offers consultancy at competitive rates to its member schools. We have a growing list of experienced consultants who offer advice on all aspects of school leadership, including compliance, preparation for inspection, curriculum, school development planning, SEN(D), EYFS provision and boarding.

Please note that schools should contact a chosen consultant directly from the details provided and not via the ISA office. All arrangements are made directly with your consultant.

Consultants featured on our website have agreed to abide by the following indicative discounted rates for their work with ISA schools:

Half day: £175                           Full day: £325

These may vary slightly depending on the nature of the work to be undertaken and degree of preparation, but should not be significantly different from those published. Please do contact ISA HQ if you find otherwise.

The consultant will invoice the school directly, which will include travel and subsistence costs, but only as agreed in advance.

ISA welcomes feedback on the quality of the consultancy: email Alice Jeffries, ISA’s Professional Development Officer, on
