The Graduate Student Instructor Oral English Test (GSI OET) is a procedure for testing the spoken English of prospective graduate student instructors at the University of Michigan whose undergraduate education was at an institution in which the language of instruction was not English. The evaluation procedure is a performance test that consists of four tasks that assess a test taker’s competence and effectiveness in the type of communication typically used by GSIs at the University of Michigan.

GSI OET Test Format

  • Semi‐structured test
  • Delivered digitally via Zoom
  • 1 candidate and 2–3 evaluators (senior, junior, and optional faculty)
  • Recorded for quality assurance purposes

The GSI OET contains 4 scored tasks:

Task 1: Warm-Up

Task 2: Lesson Presentation

Task 3: Office-Hour Role Play

Task 4: Video Questions

Task 1: Warm Up

Warm‐up has two aims: to acquaint the candidate with the test format and to engage the candidate in a brief conversation with the evaluators about his/her background and educational interests. Candidates are encouraged to participate actively in the conversation and contribute to the development of topics by offering extended responses (rather than “yes” or “no”) and asking questions of the evaluators.

Time: 3 minutes

Task 3: Office-Hour Role Play

The candidate engages in a problem‐solving situation with one of the evaluators, who assumes the role of a student visiting the GSI during his/her office hours. The “student” seeks advice or guidance about problems related to administrative matters or personal academic problems.

Time: 2-3 minutes

Task 2: Lesson Presentation

The candidate teaches a lesson to the evaluators. Candidates decide in advance on a topic or concept that they want to explain to the evaluators. Candidates choose topics that would typically be included in an introductory level class or lab session in the department that the candidate would be working. A chalkboard or white board is available for use during the presentation. Handouts may be used; PowerPoint and computers may not.

During the lesson presentation, the evaluators ask a couple questions. These questions are similar to those that might be asked by undergraduates. During this task, candidates focus on promoting audience understanding of the topic being taught.

Time: 5 minutes

Task 4: Video Questions

The candidate responds directly to five stand‐alone, decontextualized videotaped questions from undergraduate students, which represent typical student concerns. The recording is paused after each question and candidates respond to the inquiry. There is no single, correct reply to any of the questions. Candidates are expected to provide a reply that makes sense as a response.
Time: 3-4 minutes

GSI OET Rating, Security Protocol, and Scheduling

Rating Guidelines

Evaluators rate test takers in real time. During the test, each evaluator writes comments based on the evaluation criteria. At the end of the test, the candidate leaves the room and each evaluator independently rates the prospective GSI using the holistic rating scale. Evaluators then discuss the linguistic strengths and weaknesses of the candidate to reach a final rating.

Which scores indicate a test taker is eligible to teach?

A (high pass) Yes

B (pass) Yes

C (fail) No

D (fail) No

A candidate’s performance on the entire test is evaluated and all tasks are taken into consideration. This means that tasks are not rated separately, and candidates do not pass or fail the test based on performance of only one task.


  • candidates are not rated relative to each other
  • a candidate’s ability to teach is not rated
  • a single, final rating is given test reports are sent to departments within 48 hours of test administration.

Security Protocol

During the digital test:

  • Evaluators will ask the candidate to hold up their photo ID up to the camera during the test to verify their identity.
  • Evaluators will ask for a Student ID number and uniqname to verify student status.
  • Evaluators will ask for a 360 scan of your exam environment. This will involve holding up the camera or laptop and rotating it to give a full view of the desktop and the areas surrounding the candidate during the test. This is the standard protocol for remote testing.
  • Evaluators will ask the candidate to hold up their cell phone(s) to the camera and switch it off.

Should a candidate have any concerns about the security protocol, they should contact

Scheduling a GSI OET

  • Tests are scheduled by the departments where prospective GSIs will work.
  • The department arranges test dates and times with Michigan Language Assessment and notifies students of the testing schedule.
  • If a candidate has a documented need that requires  accommodations, refer to the Test Policies web page.
