Overview

The Quiz Platform provides a comprehensive set of assessment tools aimed at enhancing student learning experiences and simplifying operations for teachers and administrators. It features a modular approach to assessment creation, student assignment, and a seamless, unified student experience.

Challenges Leading to the Development of the Quiz Platform:

The creation of the Quiz Platform addressed several pressing challenges that emerged from a fragmented and inefficient assessment ecosystem:

  • Acquisition of Companies with Different Assessment Platforms: The consolidation of multiple companies, each with its own platform, resulted in disparate systems, inconsistent workflows, and significant integration challenges.
  • Non-Standard and Buggy Student Experience: The lack of a unified user interface led to inconsistent experiences, frequent errors, and confusion, ultimately impacting student engagement and satisfaction.
  • Large Maintenance Team and High Operational Overhead: Maintaining multiple platforms required a sizable support team, leading to increased costs, duplicated efforts, and operational inefficiencies.
  • Non-Scalable Architecture: Existing systems struggled to handle growing user volumes and new feature integrations, limiting their ability to scale with the organisation’s expanding needs.
  • Challenges in Adding New Question Types: The rigid architecture of legacy platforms made it difficult to introduce innovative question formats, limiting assessment variety and effectiveness.
  • Difficulty in Onboarding Internal and External Users: Complex onboarding processes, lack of standardized workflows, and poor documentation created barriers for both internal teams and external partners.
  • Lack of Version Management and Content Tracking: The absence of proper version control and tracking mechanisms caused confusion over which quiz versions were live, increasing the risk of content errors and delivery issues.

The Problem

In addition to the challenges, these critical problems underscored the need for a unified platform

  • Lack of a Common Platform: The absence of a unified solution for authoring, delivering, and tracking assessments resulted in inefficiencies. Question authors and assessment creators had to undergo retraining each time they were onboarded to a new platform, increasing time and resource overhead.
  • Reusability of Questions: There was no shared repository of questions available for reference when creating quizzes for different organisations. Since marking schemes were tied directly to individual questions, any changes to the marking scheme for a different quiz required duplicating the questions. This resulted in significant question duplication, reducing the actual number of unique questions in the question bank to just 10 to 20% of the estimated total.
  • Test Configurations: The platform lacked flexibility for customizing assessment delivery, limiting innovation in quiz formats. As a result, most companies refrained from experimenting with their assessments, resulting in standardized, fixed-format quizzes across organisations.
  • Poor Test Interface Replication: Inconsistent test experiences across different courses caused confusion for students. Additionally, some assessments required interfaces resembling government-led examination formats to ensure familiarity and compliance.
  • Question Bank Silos: The inability to share content across departments or platforms created inefficiencies. Each company had its own preferred parameters for questions, making integration complex and requiring significant migration efforts.
  • Limited Engagement in Learning: Absence of interactive features like live quizzes, leaderboards, and real-time feedback reduced student participation.
  • Poor Student Experience: Fragmented user experiences with disjointed platforms for assignments, submissions, and results.
  • Complex Classroom Management: Teachers struggled to manage in-class assessments and live responses due to the inflexibility of the live quiz system, which lacked adaptability for new features and enhancements. 
  • Lack of Multi-Language Support: The absence of granular language options created barriers for regional and non-English-speaking users. Most platforms supported language selection only at the assessment level, rather than at the individual question level. As a result, multiple versions of the same question had to be created in different languages, leading to redundancy and inefficiencies.

Our Solution

The Quiz Platform was designed to overcome these challenges by providing a comprehensive suite of tools for efficient assessment creation, delivery, and analysis. Built as a multi-client, multi-tenant system, the platform ensures seamless usability across multiple organisations, enabling scalable and customizable assessment solutions.

The platform had 3 Major pieces in order to provide a unified experience during test creation, test taking and the test correction (for subjective questions). 

Test Creation Interface

The Test Creation Interface was built to empower the authoring team with comprehensive tools for managing every aspect of assessment development. It facilitated the creation of questions, assessments, and configurations, along with drafting instructions, terms, and conditions. Beyond content creation, the interface also served as a user management tool, enabling the assignment of tests, management of user access (such as adding or removing users), and adjustment of attempt limits.

Additionally, the interface functioned as a centralised question bank, allowing the ingestion of questions from existing repositories for easy reuse and seamless integration into new assessments. This streamlined approach not only enhanced efficiency but also promoted consistency across assessments.
