I took the PSAT 8/9 as an eighth grader in October of 2015, the PSAT/NMSQT in ninth grade in Fall 2016, and the PSAT/NMSQT in tenth grade as a tenth grader last year. I use the 8/9 mainly because it was the test that I took without any preparation whatsoever. Yes, I know that SAT scores post-1995 correlate weakly with IQ tests, which is why I didn't use my more recent scores for estimation. Could my earliest score (PSAT 8/9) be directly converted to an SAT score?

In regards to the study by Lubinski, are you saying that his research might be outdated for current versions of the SAT for talent searches?
