Aeh, thank you for sharing that paper. How informative! It makes sense now that I have seen it why the WJ is given more often to the younger group vs the WIAT.
I too find it odd the AE and GE seem to be spot on between the brief and broad scores with such a difference in the Composites. I wonder what age are the Broad reading score calculations become more reliable given no data is available before 6.5 yrs. for reading fluency. It would be an interesting experiment to run DDs scores as a 5 yr old and see if the one month difference influences the broad score smile

Helianthus, I too would love to know if a higher score is possible for the younger crowd. Or at least at what age the scores look a bit more logical. This could be good information for other parents in the future.
