Students with Asperger's who are planning for college have many excellent options. Like all teens, their best choices depend on finding colleges that fit their interests, skills and personality. Depending on their executive function skills, they might choose a college with support services for any learning and functional differences they have or they can choose a college devoted to serving students who face the specific barriers to success.
The good news about special colleges is that they often prepare students to be successful at more selective colleges after only a year or two. The other good news is that parents paying for any specialized colleges for students with special conditions like Asperger's should talk to their tax advisor or accountant about related tax deductions.
