I have one DC at grammar school and another at prep school (Y6). Since the schools closed the grammar school has definitely worked hard to switch to online teaching and I rarely saw my older DC - all taken care of. Very happy with what they were able to produce at short notice. They have said they are offering a 10% reduction on fees.
The prep, not so much. A home learning pack emailed to parents with the expectation we supervise and oversee the work they have set. Various projects and presentations to prepare in different subjects. Parents horribly stressed as many are also trying to work from home. No online support at all other than being able to email a teacher if we needed help with a question. Letter from the head stated that it was unreasonable to expect 'schools should be using technology or online teaching from 'day one' and expectations were too high'. All very self-congratulatory about how well they have adapted and how hard the teachers have worked (!) (don't get me wrong - I like the teachers but in seriousness - no real contact or lessons for 2 weeks). They offered 20% off fees for next term.
Just wondering what your schools are offering and if you feel what you're being offered is fair? Of course, parents at our prep school would rather die than discuss this with each other 
as it's apparently 'just not done'.
