So the people who created the PSAT 9, the PSAT (aka PSAT 10) and the SAT decided to put them all on different scales so the scores are not directly comparable. I can find PSAT to SAT conversion tables, but no PSAT 9 to SAT conversion. We just got the PSAT 9 scores in for my two 9th graders and I'm trying to get an idea where they might be on an SAT equivalent. Anybody know where I can find such a table?

In general,
PSAT9 to PSAT add about 60
PSAT TO SAT add about 60

However,
If they were -99th percentile add 80 each
If they were average scores, add about 40 each
