It is likely that the adults are present because they are told to be there by the "higher ups." Thus, if you believe it is an issue for your students, the first step I would take is to talk to your ESE departmenent head. If they cannot directly fix the problem for you, then they should be able to contact someone (an AP) who can. These adults were most likely placed there for the well-being of the students and their learning. However, if you, as the classroom teacher in the room, sees that having 6 is not necessary then I would think your opinion would be valued.

If you have spoken to the head of the department and they have decided that it is not possible to spread the adults out throughout the day, then you could give them jobs to do. They could be in charge of any tasks that you may need help with, do not have time for or simply cannot do because it requires leaving the classroom. Also, you could find your students with the highest needs and have an adult assigned to each student to personally help them through instructions and assignments or other tasks.

You could figure out what each student needs help with and what each person is there for. Lets say one needs help with math, one reading, and one is flexible, etc. Considering most of your students probably need help daily, you could possibly coordinate where you have maybe 1 or 2 adults at a time and coordinate a good time for each adult to come in that will still benefit the student. This could possibly eliminate so many people at once.

I would have the adults assigned to a student and "buddy up" to help them stay focused on an assignment. I would not have the adults circulating the room because that gets the students nervous. Making the students feel special by having them assigned to an adult will help the students stay focused. It is only for 40 minutes and the students will most likely look forward to it every week because they know that that person is coming to see them and work with them.

If you have already reached out to a department, head, I would suggest finding a way to incorporate them into the classroom better. For instance, use this 40 minutes to do a small group activity that sorts each adult into a group with a small group of students, 6 in total. That way this mitigates the amount of distractions.

I would come up with a schedule that would rotate the adults throughout the week instead of having them all on one day. If there is more than one adult at a time, you could have one sitting in the back grading papers or working one on one with a student in another room. I would also just explain to the adults the issues of the students being distracted. Most likely the adults are there because they want to help and want what is best for the students as well.
