Welcome to the Q&A Forum

As far as accredited courses, the closest one that comes to mind is Market Motive which works with some colleges and has some excellent courses on SEO. (They have a couple free webinars each month that you can sign up for as well). I have been trying out DistilledU ($40/month) which provides beginner and advanced modules on SEO and I think it is really well done. A good starting point is to watch all the Whiteboard Friday videos by SEOMoz. They are very informative and cover a wide range of important issues.
