Please understand…support in colleges needs to be accessed by the student. There will be no one chasing your student around asking if he needs help. He needs to do this himself. At most colleges, if disabilities grants modifications, the student needs to make sure the instructors know about them…and give them to the student. Where study groups, and tutoring are provided, the student needs to ask for this help.
Note…not the parents, and not the teachers…the student.
The one thing your son needs to learn is self advocacy, and seeking help before it’s too late. No one will do that for him in college.
Another thought. There has been some discussion about his reading and writing skills being weak. The first thing you need to understand…and he needs to understand is why this is the case. Is it word decoding? Comprehension…and if so at what level?
Dysgraphia meaning he has difficulty writing with a pen or pencil? There are so many ways to accommodate this…voice activated software, regular keyboarding skills, etc. What has he used that was successful in the past.
I think a full assessment of these skills with someone experienced in young adult learning issues would help everyone. It sounds like his last assessment was a long while ago.
I honestly think the key to progressing for any student with learning differences is to understand those differences, and how to seek help.
