I am wondering at what age it becomes possible to get a DYS qualifying score via the WJ Achievement test.

The criteria for DYS are:
Standard score 145+ on at least two of the following:

Broad Reading
Broad Math
Broad Written Language
Total Achievement

I know that 4 years olds cannot get a 145 - is it possible for a 5 year old or 6 year old to score this high?
