I don't have experience with this particular program but my daughter has been in a Montesorri school for a bit now and I love it. There is definitely structure to the program, and we haven't had any issues with confusion between home and school (I love Montessori but it's hard for us to model it exactly at home). She started at 3.5 so she was potty trained already. Montessori has worked well for my daughter, who is rather sensitive, because of the mixed ages, freedom to choose the activities she wants to do, and the one on one attention she gets from her teachers. If you have more specific questions about Montesorri in general feel free to message me.
