How GapSense Works
GapSense
AI-Powered Learning Gap Diagnostics for Ghana
Empowering teachers to identify and close foundational math gaps through WhatsApp
UNICEF StartUp Lab Cohort 6
Application • March 2026
Ghana's Hidden Learning Crisis
Of children aged 7-14 lack foundational numeracy
UNICEF MICS 2023
<25%
Primary 4 at math level
55%
Have misconceptions
"Teachers know students are struggling, but can't pinpoint which foundational skills are missing."
Why Current Solutions Fail
• No way to assess foundational gaps
• Paper tests take weeks to analyze
• 120K+ teachers lack training
• Class sizes of 40+ students
• Parents don't know child's gaps
• Language barriers to resources
