All my courses are designed for small private teams, delivered live and remote, and fully tailored to your training requirements and schedule.
I have taught "a lot" of HTML5 classes, and I am always amazed by the new things that keep coming out, and how often it changes, even after the spec has been set (go figure!).
The point I am trying to get at; is things change in HTML5, and they change a LOT. So it may be wise to get your team on a customized 'refresher' course every 6 to 12 months.
Countless (pointless) apis are out now too, such as the battery API, and working with gamepads and touch event that account for your 6 fingers (yes I said 6). With this HTML5 API overload it is important to take stock of which APIS can be beneficial to your projects, and dismiss the ones that aren't, and sort out the good stuff from the bad.
If your team has been living under a rock and not familiar with HTML5, then I assure you that your team is in for a treat.
