At both his mother's and our home, he doesn't understand a "consequence," that one action leads to another. He requires being told to do something many times and if he wants to, he will. He also lies. He's so believable and insistent that he's telling the truth, yet he knows that we'll check. I'm concerned about his behavior.
Where can I find information and advice? Our school does not offer any type of testing, so I'm on my own and don't know where to begin.
You really must have an evaluation that will look at all the possibilities before an intervention plan can be recommended. If your stepson is enrolled in a public school, the school district (but not necessarily each individual school in the district) must offer evaluation services. Even if he is in a private school, the school district you live in must provide the services if you request them.
Contact the Coordinated Campaign for Learning Disabilities (1-888-GR8-MIND), the National Center for Learning Disabilities (1-800-575-7373), or Children and Adults with Attention Deficit Disorders (1-800-233-4050). There must be a branch of a parent advocacy group in your community that they can refer you to. You need someone appropriate to help you navigate the "system" to get an evaluation for your stepson plus services to support his needs.
