IAPS is delighted to offer an opportunity to link with the association in a new and exciting way

We seek partners who share our values, not least to pursue excellence in our respective areas of operation,  but also fundamentally seek to provide services which improve the educational lives of children. Our agreements will run for three years in the first instance and our premier partners will have exclusivity of representation in their area of commercial work.
