DCs school have starting using Accelerated Reader. School have been quite vague & I can't work out the book levels. DC has been told they have a ZPD of 4.4 to 6.6. Google tells me that the book levels equate to school grades in the US, so 6.6 is the level you'd expect a 6th grader (age 11–12, so year 7 in UK) to be reading (I think). Does anyone know if this is correct? And how does this relate to scales scores? I'm so confused...
