If this Private or Public school?
Because-- public and private schools, have totally different means, to handle and accommodate, SPED or special needs kids.
Public schools, have a SPED department with SPED educated and certified, professionals, who are WITH the child IN class, and aide them.
And they, if the parent requests it, can have an IEP or evaluation etc., and receive services, for their child.
In Private schools, (at least here in my State), they do NOT have to have, nor have, SPED departments or SPED trained/educated/certified, Teachers.
A regular Teacher.... keep in mind, is NOT a SPED trained, "teacher." They are not, specialty trained nor educated nor certified, for SPED or special needs, children.
So know that.
To me, your way to problem solve this is: to see if your son's school does have a SPED department, and Skills Trainers and SPED teachers.
And if not, he probably needs to go to a school, that does.
Because, you want him to have, help for his issues.
Again, regular Teachers, will not and do not know... how to handle/manage/problem solve nor create an IEP for a special needs, child.
You need to talk to the Department Head, of a school's SPED department. To attain, services for your child.
In schools, there are regular classroom Teachers, who thus have Education Degrees. And then there may be, SPED Teachers...who thus have, Special Education Degrees, and the certifications, and the training, for it.
2 roles. And 2 very different, jobs.
