The cost of any private school in my area is in the range you described. Some are good, some are not. My daughter has done extremely well in a Montessori school so far. It is unfortunate your friend’s son did not. Montessori might not have been for him or the school might have just genuinely sucked. My nephew didn’t do well in Montessori and my sister had to pull him out. He’s doing better in a public school. My mother and mother-in-law were professional teachers (elementary/middle school) with graduate educations (masters-level for my mom and specialist with most work complete for her Ph.D for my MIL) and both approved of the school and my daughter’s progress. So, I guess, I’m personally not very worried about the horror story you described.
