I’m pretty confused here, but I’m only posting at the urging of Basandre who says I might as well see if someone can clear up my confusion.
I originally ignored that IQ converter Tamerlane posted. I had my IQ tested once, in elementary school for a gifted program, and my mother did not tell me what my score was, only that I was NOT accepted for the program. Many, many years later she told me I’d missed the cut-off by two or three points, and that made the whole experience (to her) that much more frustrating. I don’t really recall much of it, except that I had to go take a bunch of tests on a Saturday.
I did eventually give in and go use that converter. I used my most recent GRE scores (verbal + quantitative is what it asks for). I had to retake my GRE last year, as they expire every five years. Five years ago, I took the GRE with a week of prep time, and didn’t really study. This year I studied haphazardly for a month or so, and I believe my scores were significantly higher as a result. If I can find my old score reports, I’ll check, but that’s unlikely.
If I’m correct that my GRE scores were higher this time than last time, doesn’t that mean my conversion would cause it to skew high in assessing me? I can’t be sure, because I was never told what my elementary school scores were, so determining if this tracks similarly is impossible for me.
So, given that it’s based on a test you really can study for (in my case at least), the converter seems like a bunch of bullshit. I have a very hard time believing, based on the numbers in this thread (that 130 is very high) that my score should be high. Especially if 130 is genius level, and I wasn’t admitted because I wasn’t quite smart enough, it sure seems as if I should have been admitted.
I think 145 may have been the rough cut off for my school system as well, olivesmarch4th. In that case, perhaps these do track decently, since that would mean a 142 or so wouldn’t be admitted. Using that converter, my Stanford-Binet score is 148, my Cattell score is 172 and my Wechsler score is 145. I could see how I might have tested at, say, 142 back in elementary school and roughly 145 now. However, I’m no genius (despite what my mother said last night), and there are days when I don’t even feel particularly bright.
And now I think I shouldn’t post this, because it’s long, rambling, possibly confusing, and doesn’t seem to say anything new. However, I’m going to post it, and put in the basic stuff that I’m confused about.
If 145 is three standard deviations above the average, that means that only 0.15% of the population has an IQ of 145 or higher, and thus a stupidly high cutoff for a gifted program. A cut off of 130 would be two standard deviations above the mean, and these programs would still only be admitting 2.5% of the population, which seems like a much saner amount (in a sufficiently small system, a cut-off of three standard deviations above the mean wouldn’t admit ANY children, and even a much larger one would only admit two or three, total). OR a cut off of 145 is a reasonable cut-off, and is not as super genius as being claimed.
Either way, I don’t think I suffered any lasting damage by not being admitted to the gifted program of that school system, but reading this thread, I’ve become confused. In the end I think I would be better off to forget what that stupid converter said, and continue not really knowing my supposed IQ.
