Course assistants (Math Ma - 21b )

Applicants for Ma-21b course assistant positions must be current Harvard university students. We do not hire first-year undergraduates in CA positions. Focus on your studies during this year of transition, and please come back next year to apply! Please

fill out a Math CA application form here if you are interested.
Applicants also have to sign up for a Microteaching session.

Calculus Course Assistant Job Description (Math M through Math 21)

All of Harvard's calculus classes are taught in small sections of around 25 students. Each section meets 2 or 3 times per week, taught by an instructor called a Teaching Fellow (TF), who is either a faculty member or graduate student in the math department. Each Course Assistant (CA) is associated with one calculus section and is responsible for working with the TF to ensure the success of the section.


Course Assistants have five main responsibilities:
  1. CAs attend each of their section's classes in order to see what is being taught, and to note the topics which are difficult for students.
  2. CAs do all of the homework grading for their section during the semester - students typically turn in a problem set each class period, and CAs are normally expected to grade the work and get it back to the students at the next class meeting. CAs maintain the gradebook, and make a weekly report of the grades and common mistakes to the TF and the course head.
  3. "CAs run a weekly 60-minute problem session. In some courses the problem sessions are used to go over homework problems and other topics which might have come up during the week. In other courses at least part of each problem session is taken up by a quiz, which you would then go over before taking questions on other topics."
  4. CAs work in the Math Question Center for an average of 90 minutes each week, alternating between one- and two-hour weeks. The Math Question Center is a general math help center that meets from 8:30 to 10:30 p.m. in the Science Center.
  5. CAs attend a weekly meeting to check in with the course administrators, and to discuss ways to improve the course and the performance of the students.
CAs are also expected to be available to help their Course Head during the semester by doing other small tasks, such as writing up homework solution sets, or helping with review sessions before exams.

The CA position is a great job for those people who want to get involved in teaching math, and in interacting with students to help them learn. It is also a real responsibility - this is a professional job, and we expect that CAs will meet all of the requirements during the semester and not let down either their TFs or the students in their sections. Students in calculus classes really count on the CAs to help them out - quite a number of students find it easier to relate to the CAs in their courses, as they are closer in age.

Pay Scale

The job usually takes between 15 to 20 hours per week for the semester. The rate of pay is 16.25 - 18.00 dollars per hour.


For a CA position in a calculus course (Math M, 1a, 1b, 21a, or 21b) you will need to have satisfactorily completed classes through at least Math 21a and b, or taken a higher numbered class such as Math 25, or 55.

How to apply

Please fill out an application form. Then sign up for a Microteaching session

Please arrive to the microteaching session promptly. During this session you will be asked to explain a problem dealing with the basic notions of calculus or linear ialgebra. If you are a returning CA, you do not need to participate in a microteaching session, but please fill out this form.
Candidates will be notified by e-mail of their chances of getting a CA job. We'll send out the notification by mid-May, but final decisions cannot be made until after sectioning is done for the calculus classes in the summer (as the number of jobs depends on enrollment and on how many sections are run). Those people who are told that it is likely or possible that they have a job must attend a half-day training session that will take place several days before the academic year begins in the fall.

If you have any questions about the job, please contact Hakim Walker (
