I have been thinking a bit about ratio IQs this week. I understand the reasoning for changing to the new method/s and it seems sound to me. But I think giving a child's IQ as a mental age is likely to be more accessible to teachers (and parents) than a number. I suspect a report stating that my DD had the reasoning ability of say a 7 yr old would have meant more to her preschool teachers than a number. They might still have said they didn't see it, but it would perhaps have been easier to say "And what level of engagement and persistence would you expect a 7 yr old to have with this task? Would being keen to return to self directed imaginative play be normal for a 7 yr old faced with this task?"
