@collegemom3717: Citing one year of data does not establish a trend. If I may ask, what is your source for that one year of data at Harvard, Penn & Yale ?
I am not convinced that work experience is helpful with respect to law school admissions. I also think that it is incorrect to assume that just because a student is not a K-JD that the intervening year was primarily about work experience. I suspect that those who delay entrance into law school for a year do so primarily to prepare for & to boost their SAT score. Additionally, any “recent trend” may be an anomaly due to the recent dramatic decrease in law school applications for a period of years as poor employment prospects & huge law school student loan debt made headlines repeatedly.
@oldfort: In your daughter’s case, work experience seems to have been a factor especially since it was probably the Southern District of New York. Admittedly, internships / externships at US Attorney’s office is relevant work experience. The US Attorney & the Ass’t US Attorneys in the Southern District of New York may have relationships with Columbia & NYU.
Law schools buy LSAT scores. While probably true with respect to Georgetown in your daughter’s case, not so for NYU & Columbia which is unusual.
P.S. I think the OP understands the process as illustrated in the original post which started this thread.
