I am not sure what to make of the SSAT at the higher levels (>80%) since it appears that 3 questions answered correctly can swing a sub section percentile by as much as 10%. Looking at scores for 2 separate tests taken 2 months apart revealed this. I think that it serves as a reasonable mechanism for screening out applicants for some schools. But once we start talking about “super scoring” and getting to the higher percentiles, I think that there is no way that you can argue for its impact on future success at age 13. I think that personal qualities innate and learned are better predictors.
