My son just took the DORA, and while overall I like the test ($20!!!), some sections have so few questions that a few lucky guesses could make a huge difference. They are all multiple answer questions except for the spelling one (not sure about reading comprehension, DS hasn't done that one yet). I know DS guessed randomly on a couple of questions and got lucky, giving him a vocabulary of a 10th grader (he is 5yrs 3months). He also topped out the word recognition section as a 12th grader. He is a fluent reader, but he's not THAT good
I wouldn't base any serious decisions on the test.
