A snapshot: international schools in London considered (but not necessarily chosen) by English-speaking expats.
Schools with a full GSGI review are noted with

(pending) means that the school is on our list to review.
By full GSGI review, we mean school write-ups that are completely selected, researched, visited and written by our own editors. Our final reviews take the good with the bad, warts and all, but we look for a preponderance of good before we drill down for in-depth details and descend on the school for an exhaustive visit. We are aware of the other schools on this page and we continually add or remove schools, as deemed appropriate.
