The only thing was that she had to start at the most basic level of every activity and show her mastery before being allowed to move to the next, so it took her some time to actually be allowed to work at her level.
Not sure if this is true for all Montessori schools. The one my DD attends is not accredited so I guess the teacher does not have to follow all the rules. She does allow DD to work at higher level material. In fact, the teacher has been very receptive. For example, when I told her that DD is adding/subtracting or spelling etc, she said," well, she must have learnt by observing the older kids. i don't see any reason why she can't be introduced to those materials so she can work on them on her own." I agree that it all ultimately depends on the teacher.
