One important element for any résumé is to show that the candidate has never stopped learning, even after completing degrees or even advanced degrees. Employers like to hire people that are on the cutting edge, people that understand you can never become satisfied with the amount of your professional education.
When a candidate has no college or university degrees the task of presenting training becomes even more critical.
Conferences, seminars, one-the-job or in-service training should be presented (but briefly always) so that a potential employer understand that you understand new concepts, have experienced new ideas ad industry innovations. That the candidate to be interviewed is forward-thinking with a solid grasp of where his/her industry is going.
Day-long, cohesively built programs are one great source of continuing professional education.
Note: Too much emphasis on formal training can quickly become very boring, so just list degrees (if any) and state that you have had “…extensive continuing professional education and training in career related topical issues.”
