<p>@sqrt(2): the SAT curve is not predetermined, unless the test has been used in its entirety before, which is uncommon. Yes, the ETS determines the curves between the administration date and the score release date. Computers and scanners are pretty good at this type of thing. This can’t be done ahead of time since the difficulty of the test is only approximately known beforehand. Student performance on questions on the new test that are repeated from previous tests is used to eliminate student quality as a variable and then to determine test difficulty.</p>
<p>Fignewton, are you sure about this? Because I’ve been getting different responses…</p>
<p>thank u rayankees</p>
<p>I also know for sure that the curves are predetermined. My SAT Writing teacher graduated UCLA where they made SAT Writing and he told me so.</p>
<p>Anybody know how this CR compared to the one in may?</p>
<p>It is done ahead of time… that’s what the experimental sections are for.</p>
<p>They calibrate it so that a person who say, got a 770 on writing, would be on track to getting a 770 based on his experimental. Of course, there will always be outliers who did really good or bad on an experimental, but. This is why scores are truly interchangeable, and May SATs are just as hard as March SATs when you factor in the curve, and 2005 SATs are the same as 2011 SATs, etc.</p>
<p>It’s a fairly precise science. Ya gotta pretty large sample size, so the central limit theorem is on your side.</p>
<p>this would be my estimation of the curve… i’ve taken most of the tests in the blue book and here is what i felt…</p>
<p>CR: Vocab was medium, passages were easy, but some of the questions were ambiguous.
W: Multiple choice was easy with the exception of 1 or 2 on the paragraph…
M: In every practice test in the blue book, i finished most math sections with 10 minutes to spare after checking and i got 800s. while i am quite sure i got an 800 on the math section, i had (relative) difficulty with a lot of the questions, so i’m going to say that it was pretty hard.</p>
<p>Here’s my guess for the curve (remember, it’s just a guess).</p>
<p>M:
54=800
53=780
52=750
51=730
50=720
49=700
48=690</p>
<p>CR:
67=800
66=800
65=800
64=780
63=760
62=750
61=740
60=730
59=720
58=700</p>
<p>W:
49=80
48=77
47=75
46=73
45=71
44=69
43=68
42=67
41=65
40=64</p>
<p>that CR curve might be too generous. that’s the same as the curve for january, which i thought was harder. then again, i might have just gotten better.</p>
<p>@Marinebio444: yes, I am sure. A somewhat technical reference is [this</a> College Board white paper](<a href=“http://professionals.collegeboard.com/profdownload/pdf/rn14_11427.pdf]this”>http://professionals.collegeboard.com/profdownload/pdf/rn14_11427.pdf).</p>
<p>If you are really interested in learning about how equating works but don’t want a degree in psychometry, I suggest [this</a> ETS paper](<a href=“http://www.ets.org/Media/Research/pdf/LIVINGSTON.pdf]this”>http://www.ets.org/Media/Research/pdf/LIVINGSTON.pdf).</p>
<p>Any chance a 48 would be a 700 for this June SAT?</p>
<p>I kinda doubt it, I thought the math was a lot easier than the March, and the March math had a 50 as a 720…</p>
