Imagine… if there was an ISAK lower school!

Dear Friends of UWC ISAK,

UWC ISAK is celebrating its 10th anniversary! We are proud of where we’ve come from, and we are excited about the next decade.

At this important milestone, we are wondering – in pursuit of broadening our impact, could an ISAK Lower School be considered as one of the options and would it be feasible? A school that embraces ISAK values and vision for a better future?

As we embark on this journey, if you would like to participate in possible market research and receive updates, please subscribe to our mailing list.
