Our solar design and install course is a little different in that it’s a mix of self-paced online learning and three-days face-to-face installation training, whereas some others involve taking a week off work to get it done in five days or so. That’s one of the struggles, just making sure that our content is being kept up to date with the changing products and that we are creating content that is relevant to our students and not outdated by the time they get out into the field. An example of a non-compulsory update would be where we might have an informal conversation with a student or students about how they found a course and get ideas about other things they might be interested in learning.
