Understanding SSAT scores
Just got my 8th grade son's SSAT scores. I'm surprised at how the scores translate into percentiles. On math, he got a 716, which seemed like a pretty good score to me given that 800 is the highest. But that only translates to the 64th percentile. Seems like that must mean that scores are really tightly bunched in the 700s, which surprises me, especially for 8th graders as presumably they expect the older kids do do better on math. Is this normal for the scoring to translate to the percentiles this way? It's very different than on the reading and verbal (for instance, a 725 on reading was the 93d percentile).
