Gosh, I think that's a really bad idea. School personnel cannot insist/require that parents place their children on medication. Now, having said that, I have been in some meetings where teachers have SUGGESTED it, sometimes strongly, and even shared their experiences with what a difference the med has made with their own children. But school personnel cannot require it.
As a school psychologist, whenever I have parents who do not wish to follow this route, I make it very clear to them that they must supplant a very strong, consistent behavior management program, to be coordinated between the school and the home, and that this MUST be followed on a daily basis. It's important to sit down with the child in developing it & have him/her engaged in creating the goals & defining the rewards. Then....stick with it!!! And, of course, every behavior management program MUST be phased-out over time, as the child has a sense of accomplishment & develops an internal desire to "do the right thing" on his/her own. A big part of this program HAS to be teaching the child EXACTLY what behaviors/skills are being expected, with modeling & adult-guided practice for those skills!!!
