Can't say i learned any of them during my social education, still earning my living as social worker in europe....
some management can be part of a few social studies but it really depends....
math and languages should allready be known from previous education but neither are part of social studies themselves.
Social workers may be generally seen as being "left" but i'd like to point out quite a few of them are working for the justice department, immigration, correctional institutes, police, army, etc. Their personal views can be left or right like anybody.
