A Funny Thing Happened On the Way to the Forum!!

When we administer test to children (or adults for that matter) we expect that the scores we get will be derived from a representative norming sample.  The WJ III^® has a wonderfully large and diverse sampling but one must look closely and ask WHY?:

Why does a score get generated for a test on which the technical manual (Table A-1, page 115) reports no one in the sampling? And why, at the same time does the test NOT report scores for a test on which the same manual (page109) reports 150 children in the sample?  Below is the proof:

BLACK indicates normative data at age 2

BLUE indicates no normative data at age 2
