Teacher Development Aotearoa (TDA)
Teacher Development Aotearoa (TDA) is a not-for-profit organisation dedicated to supporting and inspiring kaiako and teachers throughout their professional learning and development journey. TDA partnered with Arcanum to begin leveraging AI in a secure, effective, and responsible way.
"What once took us two months of intensive analysis now takes just two weeks. The document summarisation application has transformed our impact reporting process. Our team can finally focus on acting upon insights rather than just generating them. Numa's AI capabilities have given us back valuable time to focus on our core mission of supporting educational organisations and teachers."
The Problem
Turning Time-Heavy Reporting into Timely, Actionable Insights
Teacher Development Aotearoa faced a time-intensive and manual process to analyse bi-annual impact reports from 35 education organisations. Each reporting cycle took up to two months of staff time, limiting their ability to efficiently extract insights and deliver timely, high-quality feedback while balancing their broader mission.TDA wanted a more efficient approach to extract and synthesize information into actionable feedback reports, while maintaining high-quality analysis and feedback.
