Entirely dependent on a given office's staffing situation and whether you do Admin, Leg, or Comms.

If you are super organized and have good 'customer service' skills being a scheduler usually provides the highest salary floor and good opportunities to earn extra from the Member's campaign side. I've seen people go from interns to schedulers in 12-16 months.

Leg is the "standard" route when you think of Hill staffers and you should expect 6-12 months per level *minimum* (Staff Assistant, Legislative Correspondent, Legislative Assistant) and then Legislative Director (LDs). I didn't know an LD making less than $100k.

Comms is probably the area where you can rise the highest the fastest. If you understand social media and can distill your member's message well I've seen press assistants (entry level comms staffers) go to comms directors in a matter of 18 months. This is role is probably the most member dependent in terms of responsibility and salary though: a sleepy member from a safe seat won't have the same needs as a conservative/liberal firebrand. Comms is also more marketable outside the Hill itself (whether in media, non-profits, or campaign side) so that can push comp higher.
