I must say that I am torn by this situation. On one hand, I can sympathize with your concern about his academic status after having to miss the first 4 weeks of Junior High. On the surface, the punishment does seem a little excessive for a 6th grader. Why did they call you to tell you they decided to make him go to the alternative school for 6 weeks rather than the original 5 days? I mean it's too bad this happened so close to the end of the school year because if it had happened earlier, his punishment wouldn't have to be carried over to the next school year and his pre-AP classes wouldn't be affected.
But here is where my thinking tilts a little more towards NOT fighting this battle. If he had done this 6 weeks ago, would you have even considered fighting this punishment then? I mean, if the consequences wouldn't interfere with his pre-AP class, would you think that same penalty was fair? This is the nature of consequences. We can't pick and choose WHEN they are ok or not. Yes, the reality is he is paying a higher price now than he would have paid 6 weeks ago if the punishment were the same because of the timing, but that's what consequences are.
The fact is possessing alcohol under the age of 21 is illegal. Taking alcohol to school is illegal for anyone at any age. If he were older, he would be suffering far more severe penalties than 6 weeks of alternative schooling. I will assume your son really doesn't have any alcohol problems, because truthfully, that's the most important issue you should address, not how this will affect his academics. But assuming it's an issue of making a stupid mistake over one of far greater concern, I really believe you will be doing him a disservice in the long run if you try to fight this battle for him. The punishment may seem excessive to you because it will affect his academics, but it really isn't. If you try to lessen the consequence of his actions, you would most likely negate the positive affect the punishment is meant to instill in your son regarding any future indiscretions. And believe me, as a mother of a 23 year old son, I can attest that there will be more.
If your son works very hard once he returns to junior high, it's quite possible that he can catch up to the rest of his classmates. You might even be able to arrange for the extra pre-AP schoolwork to be given to him at the alternative school or you could pick it up and administer it yourself during those first 4 weeks.
I fully advocate standing up for your child when they are being treated unfairly, but in this case, I think the punishment does fit the crime. It's just really bad timing...but that's life.
