Now the funding issue may have changed since I had my high needs daughter in school but basically they would have to reinstate funding if he wanted to return to school. They should hold onto that for a good 6 months or so or do a reassessment before he re enters the school.They say it disappears the moment you leave but I've proven that wrong time and time again!
As far as DE goes enquire as to whether they can fund an aide, usually their funding assessments are done toward the end of the year for the following year. However in your situation it could be different. I would contact region and speak to someone their about his needs and what you may be able to access as schools don't always know how it all works.
My current DD13 does not have aide funding for her needs in DE. But I must say the teachers are great and they have adapted work to her level. They are so flexiable, something the school could never be.
Hope that helps:-x
