Do you have the breakdown of scores? I'm sure there will be others with more insight, but I'll add this. My DD was given something similar to this (although it may have been a slightly different version) when she was 2 years old, almost 3.
The PhD evaluated with the Brigance Diagnostic Inventory of Early Development and Developmental Test of Visual-Motor Integration. The results were as follows based on age equivalents (not as a score).
1. Body parts: 4.5 years (receptive) and 5.0 years (expressive)
2. Colors: 6.0 years
3. Shapes: 6.0 years
4. Qualitative/Quantitative Concepts � 5.5 years
5. Visual Discrimination � 6.6 years
6. Recites Alphabet - 5.9 years
7. Uppercase Letter Recognition � 6.3 years
8. Lower Case Letter Recognition � 6.0 years
9. Number Concepts � 5.3 years
10. Numeral Comprehension � 5.5 years
11. Listening Comprehension � 6.0 years
12. Visual-Motor Integration � 3.0 years
DD was 2.5 to 3.5+ years ahead of of her age peers on everything except visual-motor integration (writing skills). I was told to test again when she turned 6. DD is now 8 and was identified as MG when she tested at 6.
Hope this helps. Good luck!
