Black Diamond Middle School Reviews

I have a lot to say about this school. But Im going to keep it short, If you are conemplating on weither going to Dallas Ranch or Black Diamond, go to Dallas Ranch. You won't have the police investigating as least once every two weeks for smelling weed, or marijanna, fighting, weapons or runaways.

This school doesn't follow the rule book.  In fact they have gone so far as to remove the rules from the 2009-2010 student planner.  Hopefully they put the rules back in for the 2010-2011 school year. They really need to treat everyone equally instead of favoring certain ethnic groups. After all, if the school is more than half of a certain ethnic group, you're going to have more suspensions in that group.  They need to learn that they must suffer the consequences of their actions  if they are to succeed in the real world.  

The faculty is an excellent one, however, the administration needs to back their staff better.  The students know that they can do things that are unacceptible and they usually won't get any punishment or at least not the punishment they should.  They will go back to the classroom with even more of an attitude and continue to be disruptive because they know that they will not be getting in trouble for their actions.  This is a day to day problem which make it very hard to teach the students that want to learn, therefore letting everyone down.

The school district needs to back the administration and the staff of the schools better instead of worrying about lawsuits.  I know that lawsuits are expensive to fight but, maybe just maybe, if you stood your grounds, parents and guardians wouldn't be so quick to sue knowing that they might have to dish out the money to fight a lawsuit.

Unless there has been a drastic drop in enrollment, I think that the teacher to student ratio is closer to 36 to 1 instead of the 24 to 1 that is mentioned on one of the other websites.

You'd be better off home schooling your child or childern than sending them to BDMS.
