How do you get your basic training, and your refreshers? Do you go to ISA section meetings? Do you read books? Does your employer offer training courses? Do you wander around the InterWebs looking for necessary information? YouTube and Google it? Or do you just wing it and learn what you need to know as you need to do it, and hope your ignorance doesn't cause too much damage meanwhile?
How do you want to get refreshers and even learn the basics of the instrumentation and controls that are the underpinning of the automation profession? Do you want to go to school? Do you want classes at your work? Do you want Internet-enabled courses? Do you want mentoring and tutoring provided by your employer? Do you just want to be left alone?
