My Brothers grand-daughter ( my great niece) who they help raise... they had been fighting the public school system for 2 years...then covid hit which was a complete disaster for her and them... It has been an absolute nightmare...
She too has a speech therapist, who some how managed to keep working with her, The therapist is a saint... and has done wonders for her... she also has severe anxiety, which leads to melt downs, due to the fact she can't get the words out... they too put her is special needs classes..
Now that she is back in school, they changed her special needs teacher who has been there long term, and replaced her with a brand new out of box school teacher, with no classroom experience at all... and things are a even worse...
My Sister in law, tried talking to her about her grand-daughter, and had a folder from the previous teacher... to which the new teacher wanted nothing to do with, and told my sister in law... that she would do things her way, and she was lied to about this job, and she was suppose to have 2 to 3 assistants to do the hands on with the kids...and that wasn't really her thing... so along with a bunch of other parents going through the same thing, the school board got involved, drama and more drama. The classroom has been nothing but absolute chaos at school for my niece.. She told my brother that the teacher is mean, and yell's, and turns the lights off all the time, which means no talking... and they just sit in the dark classroom, and the teacher is on her phone...
So in January my niece... her mom... decided to look into private schools, she found one that offers what her daughter needs... Speech therapist, child mental health counselor all on staff ... She can't start till August, but at least there is light at the end of the tunnel for her... they did a verbal, and written, and audio testing... and they told her she really isn't special needs the she understand and retains just like any other kid that age, that she just needs help with speech and the anxiety ... because she has some challenges she qualified for partial scholarship for tuition... She will be going to summer camp there starting in May...so making new friends and getting her use to the new environment...
You might want to see if any private schools around you offer what your son needs, and see what they offer... if you need it in the way of scholarships, or tuition help...
My DD went to private school 1st thru 8th grade and I was a single mom, and I received help from the church from a anonymous donor to pay for part of the tuition , through a church member who made a private donation for my DD and I every year, or I would not have been able to pay for it... When my DD graduated from 8th grade, a elderly couple came up to us and gave my DD bouquet flowers, which I was kinda shocked by... The man said, when we moved here your grandparents ( which would be my DD great grandparents) welcomed us to the church. He went on to say, I was starting a new business here, and your granddad always sent customers my way and it helped build my business into what it is today..she went on to say that your grandmother welcomed me to the sewing circle even though I was terrible she encouraged me to keep trying, and made it easier for me to make new friends...and helped us become part of the community... Then it dawned on me, they were the anonymous donors... I started to say something, and thank them...she said just a hug, is all we need. Then she asked if I knew someone that needed a bit of help and I did, so I told them about my friend who's husband had just left her with elementary school aged kids.. She called me weeks later and said I can't believe it, someone has chosen me and the kids as anonymous donors for school, so now I don't have to move them.. I never told her that I knew who, or that I suggested them... When the gentleman passed away his wife made a donation so big that it covered all the books to the new library at the school.. they named the library after him... When she passed away a trust fund from her estate was set up for families that needed help with paying for school.. Each year I sent what I can to the fund, so that other kids can go to school there...
I hope that you can get the help you need for your son and your family... Sending prayers and pixie dust your way...
