Hi Gerardus,
I lived in Case Pilote, Martinique 15 years ago. I can't remember what age children start school but remember that education there is of a very high quality. For any questions you have about education there, simply look at the French model as Martinique complies with that. You must buy all of your own school books - and exams are set at night (at the same time as the children's counterparts in France)Other than that, education is excellent.
