Irish company UXTraining.com have launched the UX Design Institute, which offers an online Professional Diploma in UX Design, accredited by Glasgow Caledonian University. The course is 40 hours in duration with a 2.5 hour exam, delivered online and includes mentoring and support. I have attended a UXTraining.com course in the past, and I found them and the material to be excellent and very worth while. The Professional Diploma in UX Design is currently available for 30% off as part of a special launch offer.
