This is a question virtually every law student asks him or herself, but there are surprisingly few answers available.
On the one hand, most students know they can look to the bar passage rate of their own law schools, taking into account their class rank, to have some sense of how likely they are to pass the bar in the law school's home state. If the law school has a 70% passage rate, then it's likely you will have at least an 70% chance of passing if you're in the top half of the class. However, even that's not mathematically certain; it all depends on how closely law school grades correlate with bar passage at each individual school, which is not information that most schools make public.
Moreover, suppose you are trying to decide where to take the bar and you would like to know where you would have a decent chance of passing the first time. In that case, you will not even have your own school's bar passage rate to refer to. It turns out that state bar exams vary wildly in their difficulty, although few people talk openly about the differences. I suppose it's considered bad manners to point out that the same student who would have a 30% chance of passing the California bar exam might have an 70% chance of passing the bar examination in another state. But given the delay, disappointment, and cost that failing the bar imposes on recent graduates, I think it's important information students need to know.
This is why I developed my experimental bar passage calculator. It was clear from my prior posts on bar exam dificulty here and here that there is a need for more information on this topic. This bar examination calculator designed to predict the probability of passing a particular state bar examination based on LSAT, law school class rank, law school ranking, and bar examination state. This is an EXPERIMENTAL version of the calculator because it has not been validated against enough reliable, recent data. As a result, it may not give accurate predictions unless and until law schools provide me with data to calibrate and validate its predictions. I will revise this calculator as more information becomes available to me, but for now this should be considered provisional.
I am making the calculator public to solicit help from those who have reliable data, such as law school administrators (if you are an academic support professional or other administrator in a law school, please see note below). Please report any bugs you encounter using the calculator by email or in the comments. Note that Louisiana, Washington (state), and Michigan have been removed because significant recent changes to their bar exams make older data obsolete.
NOTE: This calculator has serious limitations, primarily based on the lack of good, recent data on bar examination candidates. As a result, the underlying data is cobbled together from aggregate data on bar examinations and the most recent individual data available. That individual data, however, dates back to 1994, and did not even include the bar examination state. Accordingly, this calculator should be used for experimental purposes only, and not to plan your life.
It would be very easy to create an accurate calculator if high-quality, recent data were available, and such a calculator could be very useful to law school students and graduates. Unfortunately, state bars and law schools are not very forthcoming with this type of data, making it difficult for students to make good decisions.
I therefore hope that Academic Support professionals at law schools will report to me (by email) how well this calculator corresponds to bar passage statistics within their own schools. If you are a law school administrator, please consider sending me feedback (by email) about how this calculator corresponds with your own bar passage statistics. I will use the information to update the parameters of the calculator and make it more accurate. This will help students who may be at risk of failing the bar to more accurately assess their prospects. If I receive enough feedback, I will be able to calibrate the calculator to provide more accurate predictions.
Where is Washington??? Do you not care about their bar, are you leaving them out because they 're about to change their archaic exam format, or did they recently secede from the Union and I just missed that bit of news?

Hi Erin,
Washington is left out for the reason you guessed, that they have changed their bar exam and therefore I have no data for the current exam. I believe they have adopted a 135 passing score (on the MBE scale) so I would guess they'd be similar to Texas (and a large number of other states in difficulty). We won't really know until we get data, because there are many factors besides the passing score that affect exam difficulty.
Best,
RA

Thank you SO much for making this program. I've been trying to figure out where to try passing and where not to bother. I know this is only provisional, but it confirms most major conclusions from my own (rudimentary) research. The only surprise was S.C. Wow, I wonder what is the point of having a 3-day exam if nearly everyone passes.

MultiStateScarredExam,
Thanks for the comments! SC is an interesting case because my original model of bar exam difficulty (which indicated a difficult exam) disagreed sharply with the multistate passing score (which indicated an easier exam). I averaged the two approaches in this calculator, so it's possible that SC ended up looking easier in the calculator than it really is. The reason is likely that SC is one of the few states that has a so-called "conjunctive" passing rule (you need to receive a minimum score on individual parts, not a minimum total score). That makes the exam more difficult than the MBE passing score would indicate. When (or if) schools provide me with data to validate the calculator I will be sure to revisit SC with special attention.
Best,
RA

I passed sc in 2010 july on first try and ca in 2012 on first try. Ca was exponentially harder than sc a big reason is sc bar tells you what subjects are tested on what day.

What is NaN%?
Posted by: Curious About Statistics | 08/16/2013 at 08:41 AM
That's a bug. If you let me know what you put in I will fix it.
Posted by: Robert Anderson | 08/16/2013 at 09:31 AM
No Alaska?
Posted by: DW | 08/16/2013 at 10:24 AM
I get NaN% no matter what I put in.
Posted by: Chetsbabe | 08/16/2013 at 11:46 AM
Chetsbabe, If you give me an example of what you put in that didn't work I will try to fix! It's working for most people though.
Posted by: Robert Anderson | 08/16/2013 at 11:53 AM
I have tried my real scores, school, etc., as well as various others - including LSAT 155, 165, 170; States Alabama, Arkansas, Florida, New Mexico (I just picked some); schools top 50, 100-150, out of 150; class rank top 10%, 10-20%, 20-30%. All give me the same result NaN%.
Posted by: Chetsbabe | 08/16/2013 at 12:11 PM
Chetsbabe,
Sorry for the late reply. For some reason the comment went into a spam filter. Could you give me one specific combination of inputs that gave NaN?
Has anyone else been experiencing this?

Comedian/Magician Harry Anderson wrote a book called "Bets You Can't Win" in which he wrote: "Suckers want to know what their chances are. Gamblers want to know the odds." A resource that helped me greatly was a book called "Pass This Bar." This was many years ago.

I'm concerned that my school's curve (grade inflation) is biasing results. How would an excessively favorable curve impact my calculation-should I rank myself as though I did worse than I did in school?

I have tried putting my information into the calculator multiple times and it does nothing when I click on calculate. No error code, no information, it just sits there.

Hi Amanda,
Thanks for letting me know. It obviously broke for some reason, but I believe it should be working correctly now.

still doesn't work
Posted by: Anne | 05/20/2015 at 02:55 AM
Should be fixed now
Posted by: Rob Anderson | 05/20/2015 at 08:48 AM
Hi:
This calculator no longer works. Is this just me? I'd like to see my results.
Posted by: Sean | 06/02/2015 at 04:08 PM
Still does not work.
Posted by: Jen | 06/04/2015 at 11:43 AM
It should be working now. It periodically breaks for an unknown reason.
Posted by: Rob Anderson | 06/04/2015 at 12:03 PM
This is interesting, but I would take it with a grain of salt. According to this, I only had a 10% chance of passing California, and I passed on the first try with no problem. I was laying out by the pool and shopping the day before the exam, and had about an hour to spare at the end of each session.

Your calculator matches well with our data on our graduates in Ohio, for what it's worth.

Ohio Law Prof,
Thanks for the feedback! I wish more people would leave that type of feedback as it's valuable for students studying for the bar.

25% to pass
First bar percentage rate 36% - pass
Different jurisdiction with different law system and different language. Pass rate 50%.
Second bar - pass
Your calculator fails.
