I think it also depends on how you answer the questions. I solidly put my DS at a level 3. But his scores reflect more like a 4. I gave the list to my mom and she put him solidly at a level 4 with some level 5 tendencies. Her assessment was considerably closer to where his scores actually fall.

For example:
Many �read� numerous sight words between 15 and 20 months.

I considered this to be actual sight words on a page. She considered this to be business logos, business signs, "Stop" etc.

Or:
Most printed letters, numbers, words, and their names between 2� and 3� years.

My DS was writing well by 3, then suddenly stopped and refused to write again until 5... I discounted this one for him completely and dropped him to a Level 1 for it. My mom again reminded me that he *was* writing before his high tendencies for perfectionism kept him from being comfortable.
