My daughter went from 18 months through 8th grade and my wife runs the school so, as you may guess, we are big fans. One thing to look for is the certifications. In the US there are (at least) two main Montessori Certification groups, AMI & AMS. The school my wife runs is AMI but I think AMS would be just as good.

What is slightly different than other experiences here is that the school is a Charter school which poses some challenges but does offer Montessori beyond the normal tuition based model.

As for my daughter, her transition has been fairly smooth. The high school she goes to has more than 10x the students as her old school so is much larger. On the other hand, her grades are good, and she is involved in a number of clubs too.

Montessori is not for everyone but I definitely recommend checking it out.
