What is a TA?

The distinction between a TA and a CA does cause some confusion and needs clarification. The CEE department views a TA as an individual who is actively and continually part of the teaching process for the duration of the appointment. A CA is an individual who supports the teaching process but is not an active part of it on a regular basis.

Let’s use an example to illustrate.

If you:

·         Prepare and give lectures on a regular basis, and/or

·         Lead laboratory sections or demonstrations, and/or

·         Spend a significant amount of time working with students in groups or one-on-one;

Then, you are a teaching assistant.

If you:

·         Assist the professor in setting up demonstrations, and/or

·         Install computer software, and/or

·         Spend a small amount of time consulting with students;

Then, you are a course assistant.

What does it mean to be a partial % TA or CA?

Students are typically appointed as an x% time TA or CA for a given quarter. The bases for the appointment are a 3-month period and a 40-hour week. Your pay for the quarter will be over this 3-month period.

Let’s say, for example, that you are appointed as a 25% time TA for Winter Quarter. You are expected to work 120 hours over the quarter to satisfy the requirements of this appointment. This is calculated as follows:

0.25 x 40 hrs/wk x 12 wks/qtr = 120 hours.

Given that the pay period is 3 months, you are effectively receiving one week’s paid vacation.

It is extremely important to remember that not all the weeks will require the same amount of effort. Some will be slow (typically first week and dead week) while others will be very busy and hectic. The appointment is, therefore, based on the cumulative number of hours to be spent during the quarter.
