This year there will be three independent CS4HS workshops. Instead of having duplicate CS4HS workshops at Canterbury and Victoria as we have for the last 3 years, Canterbury will run one that (like previous ones) is focused on the Computer Science and Programming Achievement standards, for teachers who are at beginner/intermediate level, so the discussions will be more focussed on getting started.
The Victoria one would be more general, looking more at areas of computer science that are of general interest, even if they are outside the standards (this is the model used for CS4HS overseas, and gives a broader view of the topic, which would be more suitable for those already teaching the standards.) Unitec will also be running a CS4HS workshop this year, which is likely to cover mobile applications and devices, cyber-security, artificial intelligence, and robotics.
While the organisers of the three events will be working together to coordinate, the events will essentially be independent and covering different areas, so it's fine to apply to go to more than one (if you have the time!).
