Each semester the Department of Chemical and Biological Engineering (ChBE) seeks undergraduate Course Assistants (CAs) to support faculty in CHEN classes. CAs work 1-10 hours per week depending on their availability and the course needs. These student hourly roles are filled on an as-needed basis each semester. 

Becoming a CA is a great way to:

  • Solidify your understanding of an academic subject
  • Get to know professors (helpful when looking for recommendations)
  • Improve your communication and leadership skills
  • Help your fellow students and professors
  • Earn $$$

CA tasks depend on the course and instructor but usually involve some mix of the following:

  • Grading of class material
  • Helping answer student questions at office hours
  • Leading recitation sessions
  • Answering student questions via email
  • Putting together homework questions/solutions

The pay range is $16.00-$17.00/hr as follows:

  • First Years & Sophomores: $16.00/hr
  • Juniors: $16.50/hr
  • Seniors: $17.00/hr


  • CHEN or CBEN undergraduate student
  • We strongly prefer students who have received an A or A- in the class, though those with a B+ will also be considered.

Student hourly positions are not permanent employees and hired on a semester-by-semester basis. This position is eligible for employee sick leave earned monthly on a prorated basis. The ChBE Department does not provide internships, Research Assistantship (RAs) or Teaching Assistantships (TAs).

Interested applicants for CA openings may email the department of Chemical and Biological Engineering at chemeng@colorado.edu with the following information:

  • Subject line: “CHEN Course Assistant Position”
  • Name of the course(s) of interest
  • A brief statement on why you wish to be a CA
