Seven-year-old James Farrell has Angelman syndrome, a genetic disorder characterized by major learning disabilities, and needs special attention at all times.
Describing the school his son went to Farrell stated "I would go in and visit every now and again unannounced. I would walk in and, God bless them, the two aides and the teacher weren't really that interested.
"Initially I had the anger as the father of one of the kids, and at the same time they didn't know any better. It was truly their ignorance."
He said he thought the school was fine at first "We found a class that was a special needs class within a typical mainstream school. James' class had eight or 10 students of various degrees of disability and all had different conditions," Farrell told Ryan Tubridy on Irish radio.
"There was a couple of kids with Down syndrome and cerebral palsy and James has Angelman Syndrome.
"All these conditions are delicate things and there is a very specific treatment for each condition and yet all these kids were barreled together.
Farrell then moved his young son into a different school.
"There is no segregation. At least 10pc of every class are special needs and there about 20 kids to a class," he said.
"I've observed James' progress and the kindness and the compassion it breeds in other students. It really makes for a more inspired and more community based society.
"James is great, he's really cool. He's started the equivalent of first class here."
The actor recently contacted Dublin parents Alison and Tommy Boyle who were fighting for their disabled son's right to attend school.
