In France, family education is legal. School is not compulsory. As part of the IEF, families have free choice on how to provide instruction.
Correspondence schools: there are many schools by correspondence and it is a little difficult to make a choice :
to quote some on which I inquired and made an opinion I will quote : the school Ker Lann (who s' stops in 3rd), the courses PI, the courses legendre and the CNED. The best known is certainly the CNED (National Center for Distance Education).
And it must be admitted the least expensive of all !
In our case, we will make a mix of these two solutions ... a little IEF with a little CNED and a lot of patience !!!!
