I am familiar with two different programs which (as far as I understand) teach women to be halachaik authorities. Graduates of one program--Yeshivat Maharat in New York--are called Maharat. Graduates of the other program--Nishmat: The Jewish Center for the Advanced Torah Study for Women in Jerusalem--are called Yoatzot Halacha.
What is the difference between Maharat and Yoetzet Halacha? I seek differences in what they learn and in what their level of authority is.
As a follow up question: my impression is that the second program is (more or less) universally accepted among Orthodox (or at least Modern Orthodox) Jews, whereas the first program is far more controversial. Is this true? If so, why?
