Hello,
 
I can understand how frustrating this is for you. It sounds like part of the difficulty you're having is with the communication between you and the school (because they didn't tell you about the homework situation).

There's not a federal law (or any state laws that I know of) that requires all students to be included in field trips - even educational ones. Field trips are a wonderful way for kids to learn, but I think in most schools they're considered a "privilege" rather than a "right" and many schools keep kids back from field trips for behavior issues.

That said, I think you should call the school/teachers to talk about your son's situation. Rather than worrying about whether or not their decision is legal (or even fair), I'd just focus on how to help your child succeed under these terms. Let's face it, it would be a wonderful accomplishment for him to bring his homework in every day so this field trip could be a great "carrot" for him.

You could say something like this to the teacher "My son and I are completely committed to his being able to go on this field trip. I understand that this means he needs to bring his homework in every day between now and then. Here's what I'm going to do to support his efforts (create a sticker chart at home, put a sign on the inside of the front door that he'll see before he leaves, put a note on his seat in the car so if he's getting in without his homework he'll be reminded, etc). What can you do on your end to help make sure he succeeds?" Hopefully they'll say that they'll make sure the assignments are clear to your son, that they'll email you the assignments, or some other steps to help make sure this works!

The bottom line, I think communicating with your school is the way to accomplish your ultimate goal which is for your son to be able to be part of this wonderful learning opportunity.

Good luck!

If your child is on an IEP, check it.  There should be a spot that states what general education activities your son will be involved in.  The IEP will over-rule the school.  If it is not in there, call an IEP and discuss it there.  Ask the case carrier to set up the IEP- if they don't, put it in writing (your request to meet) and the school has 30 calendar days to hold the meeting.  You may set up different criteria for your son's homework and the wording should be stated in the accommodations section as well as the team summary.  Good luck.

If there is an IEP, you need to speak up! do not let the school bully you or your child, and it's an educational trip!!!  Say somethig fight it, you will win!!!
