New SAT Scores Compared to Old SAT Scores

Would you guys say that this table is accurate?

However, when I looked at the concordance tables on CollegeBoard, it was off by about 100 points. For example, a 1530 on the first link would be around a 2300. But on the concordance tables on CollegeBoard it was around a 2200.
Why is this?

I would trust CB’s latest concordance tables since they’re CB’s. I assume that particular Prepscholar table was made with an earlier version of CB’s data. Have you tried using CB’s score converter?

Yes. But even for that they said it was a rough estimate.

Do you have a guess on what a 2200 on the Old Sat would be on the New Sat? @flatKansas

No, I don’t. Sorry. I just know that the newSAT apparently ended up generating higher scores (relative to the oldSAT). So the new scores concord back to “less impressive” oldSAT scores than originally thought.

@flatKansas Do you know if it was significantly higher scores?

Depends what you mean by significantly. I’m guessing ~50 pts in the 2200 range but I can’t google anything to support that reality.

What is it that you’re looking for exactly? Did you get a 1530 on the newSAT and you’re trying to figure out how “good” it is? Do you have a new and old score and are trying to decide which to submit?

@TheAvidSeeker
The College Board converter is the best thing to use. The PS tables were published before the new SAT results were even released and are not accurate. A 2200 on the old SAT converts to a 1510 on the new SAT. A 1530 on the new SAT converts to a 2230. That’s using the total 2400/1600 scores. If you convert your section scores your results will vary a bit.

@TestRekt What do you think colleges would use for admission purposes? Because it said it to remember that these concordance scores are only estimates.

They are different tests, so by definition the conversions are estimates. If I time you in the 100 yard dash, I don’t know exactly what you are going to do in the 100 meters, but I can estimate it pretty well. And if I am choosing the best runners, I’ll want to use that estimate. Colleges will depend upon the College Board tables because they are the official guidance. It’s no different than the way they have had to judge SAT and ACT scores in the past.

@TheAvidSeeker Colleges are of course going to use CB’s most updated numbers. That Prepscholar post was ALSO based on CB’s own numbers, just an older set of data. Prepscholar even has newer versions using the newer data. There’s zero chance that given two sets of concordance estimates that a college would actively choose an outdated set, and less than zero chance that colleges would choose an unofficial site’s interpretation of an outdated set.
