My son got a "7" on digit span the first time he took the WISC IV at 6 1/2 years. I remember that he seemed to do okay on numbers forward but really poorly on numbers backward. But I do not know how many he got right. The score is 'scaled' so basically you get like two points for each right answer, it's totaled (I think that is the "raw score"), and, then, the tester looks the raw score up on a chart by age for the scaled score.... so it's sort of hard to figure out.

Take heart my kid's digit span score and letter number sequencing score improved significantly over a year and half...
