Another choice open to parents when it is available is the 'charter school.' This is a public school established with the freedom to follow an independent teaching method, specific curriculum, limited entrance policy. My 6 year old grandson's name was drawn and he is enrolled in our Montessori model K-8 charter school. His sister will therefore automatically be eligible. Small classes, excellent curriculum individualized to the student. For instance, he entered kindergarten reading whole books at the 4th grade level (has a good Mom, read to him and played alphabet and word games). Because he does not always know the meaning of a word which he can easily read, his teachers are concentrating on vocabulary development.

Ah good, I always like free choice. The danger ofcourse is that students choose what they want and not what they need, that is why freedom is often limited in profiles.
But with proper supervision it can certainly bring out more of the potential of a child.
