If you have a good relationship with the current teacher, and you have an idea of the teacher(s)/classroom(s) you would like for next year, you can ask your current teacher for some "buzz words" that fit the classroom you desire. If you aren't comfortable doing that, you can simply ask for input on your child's learning style (just to see which way that teacher might be leaning if it's a committee decision, which it often is).
For example, some classrooms might be more project-based than others, and if that's what you want then you could write something about how your child learns best in a project-based environment. Of course you'd want it to be truthful / actually fit your child's needs, but it sure doesn't hurt to get some of the school lingo in there.
