A bespoke reading assessment platform, built for 300–400 students at once
BVIS (British Vietnamese International School), a school within the global Nord Anglia Education network, partnered with Saigon Digital to design and develop a custom reading assessment platform tailored for 300–400 students across multiple year groups.
03 THE WORK
BVIS urgently needed to replace manual reading assessments with a centralised, digital system designed specifically for their academic environment. The core difficulty lay in managing a complex, multi-level reading ecosystem where quiz levels did not always align with standard year groups, demanding highly flexible logic for student access and progression. Furthermore, the system required three separate user access levels-Student, Teacher, and Admin-each needing unique functionality and dedicated dashboards. A crucial technical hurdle was ensuring performance stability, guaranteeing that 300–400 students could access quizzes simultaneously during peak class sessions. Compliance with copyright laws, preventing public display of book files, and ensuring the scalability of internally created content for future reporting were also essential requirements for this secure, modern tool.
Saigon Digital addressed these complex educational and technical requirements through a structured, phased approach that prioritised system architecture and long-term scalability.
Phase 1: Discovery & System Architecture
Phase 2: UI/UX Design for a Learning Environment
Phase 3: Core Platform Development
To deliver BVIS’s vision of a modern literacy platform, Saigon Digital engineered a bespoke educational system underpinned by several critical technical features. This included a Multi-level Access System with custom dashboards and unique permissions tailored for Student, Teacher, and Admin roles. We provided a dedicated Custom CMS for Quiz Management, enabling BVIS teams to flexibly manage and deploy internally created content. Crucially, the Reading Progression Engine was developed to ensure strict adherence to reading difficulty levels, preventing quizzes from being passed without matching the necessary academic standards. Finally, the system was hosted on a Performance-Optimised Infrastructure (leveraging AWS and NestJS) to guarantee reliability and high concurrency for 300–400 simultaneous users.
The collaboration successfully delivered a unified, high-performance educational platform that profoundly elevates BVIS’s academic delivery.
Saigon Digital helped BVIS HCMC develop a fully bespoke educational reading platform tailored to assessing children's reading comprehension in Vietnamese. From the very beginning, their team took the time to understand our goals, our curriculum, and the needs of our students. The final platform is intuitive, reliable, and genuinely supports our teachers in tracking student progress more effectively.
Yes, and concurrency is the requirement to design for rather than discover. BVIS needed 300–400 students in quizzes simultaneously during class, so the architecture: Next.js, NestJS, MongoDB on AWS, was chosen for that peak rather than for average load.
With access logic that treats level and year as separate things. A student is granted quizzes by reading level, not by the class they happen to sit in, which is what lets a school stretch strong readers and support weaker ones inside one system.
Book files are never publicly exposed. Access is authenticated and scoped per role, so the assessment content stays inside the school while remaining usable in a normal lesson.
That is the main return. Assigning, collecting and marking reading assessments by hand is hours a week per teacher. Automating the mechanical part gives that time back to teaching, which is why we track it as an outcome rather than a feature.
It is designed to. The roadmap includes gamification, progress streaks, class leaderboards and achievement milestones, to turn reading practice into something students compete at rather than complete. See web app development.
