age.  For ADHD it's four. Medians.   Since these are medians the kids who
get diagnosed much later, teen years for example, did not affect the
average.  Draw your own conclusions.  So they start school on the average
of two years after the average age at diagnosis of these two conditions.
Also, the transition to the next Piaget stage will vary (how much I do not
know).  Then too, Piaget's stage ideas have lost some support over the

While I do not question the data (child psych not one of my areas) one year
of difference in age should not cause the big effects they report.  Did
they separate the children who had been to some sort of kindergarten before
from the ones who had not?  Did not see that.  I did not do  a thorough
study of the study.  I could have found more potential problems.

All in all, we'll have to wait for replications before changing the start
of school.     Typically a first study will feature larger effects than
replications will.  Draw your own conclusions.    bill w
