Parents have filed at least 10 complaints in the last year about special education in the York School District.An attorney said some parents of special needs children complained that the district wasn’t supportive of their children’s education, according to documents from the Maine Department of Education.Several cases have been mediated, and requests for hearings with the Department of Education have been withdrawn. However, two cases remain open.In many of the cases, standard individualized education plans for students were not followed, and although parents were told students were progressing, their children were not, attorneys said.“A lot of the cases I’ve seen have similarities in where the school dropped the ball, so to speak, and what went wrong, and how the parents were treated when they realized something was going wrong,” said Amy Phalon, an attorney for Murray Plumb & Murray.Phalon said there are 12 cases that involve York County, including the ones that have been mediated.The superintendent wasn’t available to comment.
