Integrating Oral Assessment in Engineering
Bibliographic record
Abstract
The pandemic and the evolution of generative artificial intelligence (AI) systems have disrupted traditional learning assessment methods. These changes have necessitated the experimentation of alternative forms of assessment, some of which have been permanently adopted. This is the case with oral assessment in the Chemical Engineering program at Polytechnique Montréal, where this assessment method has been in use for over 15 years. Recent developments have helped to solidify the role of oral assessment in the program and extend the approach to other courses. This paper describes the principles of oral assessment, the general structure of the Bachelor’s program in Chemical Engineering, the implementation of this form of assessment over the four years of the program, and the success conditions of such a system. The originality of this contribution lies in identifying and operationalizing the elements necessary to make it an inclusive, non-anxiety-inducing, and respectful system for students.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
