School Reviews
1 3/2/2021
This middle school likes to infringe on our Constitutional rights. My son posted something on his private social media account that the school did not like so they are attempting to suspend him because they are butthurt in their feelings. After all, he voiced his displeasure with a teacher. They are saying he violated school policy and refuse to tell me how the information was obtained? I asked was it done on school time or a school device which I know for a fact it was not and have received no answers. In order for the policy to of had to be broken it has to be done on school time or on their device. So they can go to a private social media account get offended and retaliate for seeing something they willingly chose to go see. You can not make this stuff up. This school is only interested in their own agenda, they refused to work with me whatsoever. You have been warned. Do not get me started on his they are barely equipped to handle children with disabilities.
