The level of mentorship by faculty members is always valued by the students. The program is intentionally small and ranges from 15-20 students per year.
The famous collegiality of the Fletcher 'mafia' is a different experience altogether, and one learns a lot from one's peers as well, especially because the range of perspectives, nationalities, professional backgrounds, and world-views is staggering.
I would characterise my experience at Fletcher more as a “horizon-expansion” as opposed to unlearning. During my time there, I purposely chose courses that are not offered in a typical law program.
