🔒 Confidential
Context
After an in-depth market analysis and benchmarking process, we identified that the brand’s key competitive differentiator would be offering AI-powered writing and speaking assessments.
Beyond creating competitive advantage, this approach significantly reduced the operational burden of manually grading bilingual assessments, which previously resulted in high costs and long turnaround times for teachers and coordinators.
Challenge
To integrate an AI-powered bilingual assessment system into an established platform while ensuring clarity, trust, and user adoption.
My Role
I acted as the Product Designer responsible for conducting the market research and benchmarking that supported the strategic product decision.
Following that, I led the design of the end-to-end assessment experience — from test submission and AI-powered correction to results visualization — focusing on teachers and coordinators. The goal was to reduce operational effort, shorten turnaround times, and increase scalability.
