HI and welcome Yadira -
I did get your message and will respond via email over the weekend. My son uses the computer for homeschooling and needs to get back to it, I am just checking a few things for a moment.
Is your son a regional center consumer? Has there been an IEP, did he get dx from school district? My kids went to preschool special ed, you can call for an IEP meeting and request a change.
