Teacher Appraisal System (BRAC University) Case Study

Project Overview

BRAC University Teacher Appraisal System is an anonymous, privacy-preserving faculty evaluation and rating platform engineered for BRAC University. The system enables students to appraise their course instructors objectively at the end of each semester while keeping their personal identities strictly concealed.

By decoupling student identities through secure, private login credentials and one-way cryptographic verification tokens, the platform eliminates apprehension of academic bias or grading repercussions. This ensures honest, transparent student feedback while generating actionable pedagogical insights for department chairs and university leadership.

Anonymous Evaluation

Identity-Decoupled Private ID Authentication for Students

Technical Actions & Architecture

Leading end-to-end privacy engineering, secure database schema design, and institutional analytics integration:

Privacy-Preserving Private ID Authentication: Designed an identity-decoupled authentication mechanism where students log in using private credentials that separate student identification records from rating submissions, guaranteeing 100% anonymity.
Anti-Tampering & Single-Submission Tokens: Engineered zero-knowledge one-time validation tokens to ensure that each enrolled student can submit exactly one appraisal per course instructor, completely preventing duplicate voting while leaving zero identity traces.
Multi-Dimensional Appraisal Framework: Structured multi-metric evaluation forms covering teaching methodologies, course material clarity, punctuality, grading fairness, responsiveness, and constructive open-ended feedback.
Departmental Analytics & Reporting Portal: Built real-time aggregation pipelines and role-based analytical dashboards for Department Chairs and Deans to monitor faculty ratings, trend reports, and performance indicators without access to student identities.
SIS & Roster Synchronization: Integrated seamlessly with BRAC University's academic course databases to dynamically pull active student-course-faculty enrollments for each semester.

Project Outcomes & Impact

The Teacher Appraisal System dramatically boosted student participation rates by eliminating fear of reprisal and ensuring complete confidentiality. Department Chairs and University Administration gained reliable, empirical data to guide faculty mentorship, optimize curriculum delivery, and uphold the highest academic standards across BRAC University.
