The honors program at UW-Seattle is interdisciplinary. There are also departmental honors which are not interdisciplinary and are awarded by each dept. Look carefully through the honors website, there is a lot of information there, including the requirements for completing honors and course descriptions of honors courses. There is no registration advantage for honors at UW, however, merit scholarships are associated with the interdisciplinary honors program. Also, it is one way to get small class sizes in distribution classes.
