It’s in California.

My child took the “CASTL” test as part of IEP assessment. According to the result percentiles, a 6 year old who can do 2 digit vertical addition is at the 70th percentile of 6 year olds.

How come in kindergarten the curriculum is counting to 100 and addition within 10, while the assessment test shows double digit addition is well within the norm?

BTW my child didn’t learn any arithmetic from school.

EDIT: In case I wasn’t clear: there is a huge discrepancy between the standardized tests and the actual curriculum “standards”.
