A Platform Developed for the Evaluation of University Teaching

A Prototype Developed, Secured and Formally Validated for Institutional Adoption

TES currently serves four roles students, teachers, department deans, and platform administrators. each with a dedicated dashboard. Students submit anonymous course evaluations through a guided  form; teachers view aggregated results and comments for their own courses; deans and administrators access comparative statistics across departments and semesters, and export results as PDF reports, CSV data, or formatted Excel workbooks. Administrators additionally manage users, courses, evaluation criteria, semesters, and student ID cards, and can review a full audit trail of platform activity.

Three lines of evidence support the readiness claim developed through this report:
•  Functional  breadth:  the  full  workflow  (Chapter  3 of the main doc)  plus  18  additional  operational  scenarios (Chapters 4-6 of the main doc) were exercised live, role by role: creating a semester, adding and importing courses, students  and  teachers,  configuring  evaluation  questions,  enforcing  one-evaluation-per-student, isolating each teacher's data from every other, printing student ID cards singly and in batch, and generating  every  report  type  on  real  submitted  data.  Every  screenshot  in  this  document  was captured from those live runs.
•  Independent  quality  assurance :  three  audit  cycles  identified  and  resolved  concrete issues,  most  notably  strengthening  the  technical  guarantee  of  evaluation  anonymity  from  a reversible mechanism to an irreversible one, and catching a live regression in the login rate-limiter during the preparation of this very report.
•  Formal  verification  (Chapter  8 of the main doc):  a  peer-reviewable  mathematical  model  (Colored  Petri  Nets) proves  six  correctness  properties  of  the  platform's  core  workflows.
