Graded levels of difficulty in online testing, perhaps multiple choice? Different timings for tests? Extension activities? The Australian example is not what I am talking about though. I am suggesting that a school who is missing five teachers for five different subjects, may take weeks and weeks to replace them (especially in London) employ various supply teachers (all unsettling for the pupils) spend 000s and at the same time wear down staff, demoralise pupils and teachers alike - when (from what I have been reading today) there appear to be a host of companies offering a technology-based alternative.
