<p>The “metric” ?–is that really want you meant?-- is used for two purposes: the first is to give the LSs some sense of the grading system at X college. Kids DO have to worry about grade inflation at their schools! It is especially useful in giving law schools some idea of the grading system at colleges with which they are unfamiliar. While only one student from Old Widget Liberal Arts College may be applying to a given LS, the data compiled by LSDAS allows the LS to find out the median LSAT of Widgets applying to all law schools and how the applicant’s gpa stacks up against all of the applicants from Old Widget to ALL LSs. So, the law school for the U of Wyoming may never have received an application from a Widget before, but when it does, it will know a lot more info about what a 3.4 at Old Widget “means” than it would if the LSDAS didn’t exist. </p>
<p>The second purpose is to tell LSs how the applicant stacks up against other applicants from that college. </p>
<p>The LSDAS (Law School Data Assembly Service) uses LSAT and gpa’s of applicants to LS in large part because they are available. It knows the actual LSAT scores of each applicant. It receives the actual transcripts of those applicants and it attempts to standardize the grading systems as much as it can. You can, in theory, come up with other measures that might work better, but there’s no way to insure that the LSDAS would get actual, unadulterated data. That’s why LSDAS uses them bluebayoo–there’s no other reason. </p>
<p>LOTS of colleges are SAT optional schools. Others accept the ACT in lieu of the SAT. If LSDAS used SAT scores, how would it account for schools at which SATs are optional? Schools like Bowdoin and Mt. Holyoke–both fine schools–don’t require SAT scores and thus there is no way that LSDAS could acquire SAT scores from all LS applicants. Another way colleges “massage” SAT scores is to give summer or spring admissions to lower-scoring students. That way they aren’t included in USNews’ data–even though those students are enrolled in the college. Assuming that these students get lower grades in the aggregate than the students admitted in the usual fashion, comparing the reported SATs with the actual gpa’s would make the school look tougher than it is. And, of course, some kids took the ACTs, not the SATs.</p>
<p>As for gpa’s–many colleges don’t release that information. Even among those that do, the methodology varies a lot. LSDAS can’t standardize gpa’s perfectly, but it certainly does so more effectively than colleges do. For example, some colleges only count the new higher grader in gpa for repeated courses. Others count both grades. If it can figure out what the grade was, LSDAS will count both, no matter what the college itself does. </p>
<p>So, the LSDAS folks wanted to use data which colleges couldn’t “fudge” as easily. It’s certainly not fool proof–but it’s the closest thing that’s easily done. LSDAS does NOT have to rely on the willingness of colleges to give them the information. </p>
<p>The LSAT and SAT scales are designed to make it easy to combine them with gpa’s. For the LSAT,drop the 1, divide by 20 and you have a “gpa.” It’s easy to combine with a gpa, so LSs can choose to weight gpa and LSAT equally or weigh the LSAT more heavily or the gpa more heavily. (In the real world, it’s usually the LSAT.) I don’t understand lergnom’s statement about the “relative inflexibility of the gpa.” The LSAT scale correlates perfectly with the 1.0 to 4.0 gpa scale. (It’s assumed that nobody with below a D average graduates from college.) If anything gpa is a bit MORE flexible, since some schools do give A+ grades and it’s not possible to score above an A (180=4.0) on the LSAT. </p>
<p>AS far as I know, no LS CARES whether you “underperformed” or “overperformed” in college. It’s just not part of the calculation, as far as I know. Maybe it’s just yours truly, but I haven’t a CLUE what the last sentence of lergnom’s post means. Please believe that’s not meant as a personal attack–I just really don’t understand what he is saying. </p>
<p>The idea is that in a perfect world each student would receive exactly the same grades no matter which college he attended. While there’s lots of individual variation, the idea is that in the AGGREGATE those who score well on the LSAT should have better grades. So, while there may be a kid like PSedrish’s D who had a 3.2 and a 180 LSAT, it should NOT be the case that the median gpa of all those who score a 180 on the LSAT is a 3.2. </p>
<p>In THEORY, in the AGGREGATE, the 180 test takers should have a gpa of 4.0. The 160 test takers should have a gpa of 3.0. The 150 test takers should have a gpa of 2.5 NO MATTER WHERE THEY WENT TO COLLEGE. This is NOT true of individuals, of course. It’s just that there would be something seriously wrong with the LSAT if as a group those who scored a 150 had worse grades than those who scored a 175. </p>
<p>To get a rough idea of how grade inflated your college is, LSs compare the median gpa and the median LSAT. So, if one school requires everyone to take 2 math classes to graduate and lots of wanna be lawyers don’t do well in math classes, then the overall gpa’s of the kids who attend “mandatory math U.” and apply to LS will be lower than the overall gpa’s of applicants from “Choose Your Own Courses” U. So, comparing the median LSAT with the median gpa of APPLICANTS TO LAW SCHOOL at the two colleges will favor “mandatory math U.” It helps to make up for the fact that the students at “Choose Your Own Courses” U will actually have higher gpas in the AGGREGATE than those at “Mandatory Math U.” </p>
<p>To the extent that X college is grade-inflated at the LOWER end–which seems to be Sakky’s argument–the LSs will know it. The “score report” not only tells LSs your actual LSDAS calculated gpa, and the median gpa, it tells them about where your actual gpa places you among the folks applying to LS. So, if nobody gets below a 3.0 at Harvard–a theory the OP seems to disprove–LSs will know it because the score report for the 3.0 Harvard applicant will say that his/her gpa is in the bottom 10% of all the applicants applying from H. </p>
<p>At the same time, the LSs will know that in our theorectical perfect world, with a median LSAT most years of about 166, the median gpa of H students SHOULD be a 3.3, so it’s not much of a shock that a 3.0 puts our H applicant at the bottom of the stack. </p>
<p>He is no worse off than the applicant from a (real, but I won’t name it) large state U where the median gpa is a 3.1 and the median LSAT is a 149. The median gpa “should be” 2.45. So,the fact that our X state U applicant has a 3.0 isn’t going to look any better than the 3.0 from H, even though in this case, the 3.0 is close to the median gpa at the university. </p>
<p>I don’t know if that helps clarifies things or not. I’m ranting on about this because I get really annoyed when people post things like a 2.8 at Harvard is a “disgrace” or talk about how grade-inflated the Ivies are. Sure, there are colleges that are truly grade deflated–they are rare but there are some. But there’s no reason why H should have the same grade distribution as my large public U example.</p>
