“Our colleagues in the USA have an organisation similar to CAS: CSTA (Computer Science Teachers Association). As you may be aware, the delivery of computer science across the States is developing rapidly. Some school boards are in a similar position to English schools 3 years ago; wondering what to teach, how to teach it and whether it is relevant.
I have been fortunate to work with a number of colleagues in the USA, exchanging ideas and resources. During the past couple of years I have supplied starter resources focusing on using Python for foundation skills as part of the wider CS curriculum.
Knowing how supportive and developing the CAS portal can be, you may want to become a member of the CSTA group. As well as extending your list of contacts, you may find valuable support especially in the way that CS is becoming credited across the curriculum in some States and the ideas developed for the CS AP (our version of A Level).
If you would like a little more detail on the situation in the USA and how this compares to England, a report on CS can be accessed here: http://www.wcmt.org.uk/sites/default/files/report-documents/Jones%20M%20Report%202015%20%20Final.pdf
Good luck with the new A Levels and 9-1”
