I'm not sure if I'm following the whole concept. So, a five year old tests and shows his achievement level is say at around 3rd grade level. After a couple of years of ?undifferentiated? school, he's in 2nd grade and has about a 4th grade achievement level? Without actual directed learning at his optimal level of learning, how would his knowledge and skills advance?
The question isn't what is wrong with the kid, but what is wrong with the placement and pacing and content at school? And why is school wasting 5-6 hours of his day every day under the functional lie that he is learning?
