aeh can give a better answer, but it sounds like what happened is that he thought the age appropriate section would not have a high enough ceiling. My understanding is that the WIAT has different sections for different ages. My daughter has taken it twice and hit the ceiling for reading (she had a perfect score in comprehension). Apparently the reason she was able to so that is that you run out of questions for a particular age group. We wanted information for her acceleration, so he calculated her scores based on age, current grade (kindergarten), and proposed grade (first grade).
The subtests differ for different levels (e.g., I think phonics is no longer tested after grade 3 and prereading skills, etc., aren't relevant at higher ages).
So I think he used a section that was for a higher age and therefore couldn't give age based results. That could also explain why he couldn't give the appropriate subtests to generate a composite score.
If you wanted scores for DYS, you could always submit the IQ score and then include the achievement subtests that you have as part of a portfolio.
I'm sure aeh can give you more detailed advice, but that is just what I know from our experience with the test. Our psychologist recommends the WJIII for future testing because they can work up to higher levels.
