Seniority depends on the date on which members were sworn into office. Since many members are sworn in on the same day, subsequent ranking is based on previous congressional service of the individual and then by alphabetical order by the last name of the congressman.
Committee chairmanship in the House is often associated with seniority. However, party leadership is typically not associated with seniority.
