On 15 May 2025, NASCEE and TICZA hosted the first in a webinar series exploring what it really takes to shift systems in teacher education. TICZA is pioneering an Extended Student Teacher Internship (ESTI) model — bringing together NGOs, HEIs, funders, unions, and government to create real change. Using the Collective Impact approach, TICZA has learned hard-won lessons on shared measurement, backbone roles, and building a common agenda. Key takeaway? Systems change is messy, slow, and worth it.
