How many Rabbinical Schools are there in the US?

There's no single definitive answer to how many rabbinical schools are in the US. The number depends on how you define "rabbinical school." It includes schools that grant ordination for different movements of Judaism (Reform, Conservative, Orthodox, Reconstructionist, and others), and some smaller institutions might not be widely known. A reasonable estimate would be between 10 and 15, but a precise count is difficult to obtain.
