I would ask your schools behavioral specialist and see what plan you could set forth with him. Get the parents involved as well.

Have a conversation with the student individually about this issue, in a positive manner. They likely are doing this because he doesn't want to do the work, so if your put a positive twist on it he may be more willing to do work. Depending on the age of the student, you could create a "reward" system for having a growth mindset. When he positively starts working and doesn't make any sounds, he could receive a sticker or token of some sort. After so many stickers or tokens, he could get small rewards like a few extra minutes on the playground, etc.

This is a serious misbehavior that is disrupting teaching and learning and needs to be handled with strategic interventions. I would speak to the student before his high pitched squealing begins and inform him of the consequences when he starts to misbehavior. Some of the strategies to try could be, withholding a privilege or favorite activity, give him a "time out". or sending him to detention. If behavior continues, you should contact the parents to get their help in resolving the misbehavior.

Have a conversation with this student about how disrupting this behavior can be for you and the other students as they are trying to work. Have some consequences you can follow through with in case he still isn't following your directions. If after multiple warnings and minor consequences, send a note home to the parents letting them know.

I would see if I could get in contact with their parents. It's possible they may have a condition, and if not there may be a specialist who can help them. While I am by no means a specialist, it certainly reminds me of tourettes. There are specialists who can teach the student to handle their symptoms if it is such a condition.

Because it is a behavior creating an ineffective classroom environment for many, developing a behavior contract with the student may prove beneficial. There are prompts that can also be used or attached to the students desk as reminders. As already mentioned, reaching out to the behavior specialist for support might be the next best step.

Some students who are differently abled handle anxiety and tasks in different manners. This may include making noises or using repetitive motions. You might try to help the student become more aware of what they are doing by providing visual cues or making a progress chart, therefore rewarding the student when they do not carryout the undesirable behavior. Additionally, the student may need a fidget or a special toy that engages their sensory activities while they do work.

I would refer to a behavioral specialist to help with this issue. There has to be a conversation with the student that this is no longer acceptable, and he has to learn that making these noises will not always help him.

start adding consequences, like time at recess. All the other students are doing the same work but if he doesn't want to do it he can do it on his time.
