I’ve just stumbled upon Google’s ‘Educator’ program. It looks like a brilliant piece of free CPD based around online Google Exam. At the end of each exam, you receive a virtual certificate that says that you’ve passed.
It is also a gateway to applying to join sessions at the ‘Google Teacher Academy’ and attend Google Teacher events. I’m going to try and work my way through the online exams over the next few months, just to say ‘I can do it’!
