My problem is that I don't trust anything I can't check, and have found only one good piece of research from EEF. The difficulty is that current evidence won't always provide data to answer the qs they ask, and then they answer them anyway. I reviewed research for TES for 13 years, and my method was always to go back to raw data and see what had been done with it. Some research, eg Bradley and Bryant, Snowling and Hulme, Clackmannanshire, stood up to this, and some, eg Reading Recovery, did not. The further we get from the data, the less I trust the conclusions, and my analysis of research in mixed ability, here, shows one reason I distrust EEF. Sir K Collins replied, but could not fault my analysis of the evidence - it is out of date. But then, as I said at the beginning, I don't trust anything I can't check, and don't trust meta analysis and lists at all.
