School Reviews
2 10/10/2025
FBMS is great... until you have a problem. Then it is the worst. The guidance department has been great, but at least half of the teachers will blatantly ignore and disregard any requests from parents and recommendations from guidance.
Just one example: last year my child had a teacher who shouted at the class all the time and handed them worksheets and expected them to teach themselves. Then when they performed poorly she did nothing to help them learn the subject. We even tried to schedule a conference with her. She told us she couldn't fit us into her schedule the day before we were supposed to meet with her and the other teachers. When we arrived for our other conferences, we were informed by another parent that our names were indeed on her schedule. I don't know what she was playing at there, but all of the above tells me that the administration needs to get a grip on its teachers.
The other half of the teachers are great and I feel SO bad that they have to deal with co-educators like that. I really hope they tighten up a bit because middle school is hard enough as is without that nonsense.
