That's true, but what percentage of Kaplan students actually increase their score by 5 points? What is the success rate of their LSAT course?
Does Kaplan publish stats?
Actually, yes. An independent study conducted by Price Waterhouse (in 1994) showed that Kaplan LSAT students increase their scores by an average of over 7 points (7.2 to be exact). $1000 is a bargain for 7 points, IMHO.
A 10 year old study isn't very relevant today. How about a link to that study? Kaplan doesn't make it readily available, and they don't use it in their marketing. I'd be interested to read about the study, i.e. the methodology, sample characteristics (size, location, education, etc.), over what period of time was the study conducted (one REAL LSAT? Just on in class tests).
One 10 year old study just doesn't say anything about the efficacy of Kaplan's LSAT program today. But there are a lot of former KAPLAN students that do have a lot to say, and that is that they didn't think that KAPLAN helped them.
I want to restate that I believe that KAPLAN may have effective methods for taking the LSAT, but I have no evidence that KAPLAN is able to transfer that knowledge to their students.
I think KAPLAN should maintain an ONGOING measure of their students score increase (or decrease) on the REAL LSAT. Once you have at least a year (and 3 years would be an even better time frame) we could see a more accurate picture of KAPLAN's ability to increase student's scores.
