In my hometown, there's a Grant Program...Parent's As Teachers... A lady from the local school goes into homes once a month to chat with the parents and children. I was visited by this lady and it was wonderful. She'd give the kids books, toys and play games with them. This is how I found out about the free IQ testing at our city elementary school. If your school has this program, you could recommend she contact the parents of these children and then later she could suggest IQ testing to the parents.
