“Essentials of the AV industry” shaped my hunger to delve deeper, beyond just VC. This is still probably the best online course I have ever taken. I even purchased the book as supporting material and still use it today! That combined with my desire to be different, led to the CTS (Certified Technical Specialist). I wanted something with real value, something that would stand me head and shoulders above the other integrators and resellers, and something customers could feel confidence in. I was a tad too long in the tooth to try for a degree at that time in my life and actually researching multiple courses at the time, none of them are specific to AV, not even VC. Sure you can branch a little into Networking in certain syllabuses, but they are IT based - AV 'at the time' was a dark art and seemed to be restricted to skills and knowledge being passed down, hands on experience, rather than a chosen and structured career path.
