Renee Ho with Professor Wong Berlin and EDB Under Secretary Dr. Jeff Sze JP

POLICY DIALOGUE

Direct Dialogue with Policy Makers

Essai co-founder Renee Ho recently joined Professor Wong Berlin and the HK Future Economy Institute (HKFEI) team to meet Dr. Jeff Sze, JP, Under Secretary for Education, for an in-depth dialogue on Hong Kong's AI education policy and school-level implementation.

We believe school-based AI adoption requires ongoing dialogue with policy makers to genuinely match what schools need.

WHY

01

HK exam-aligned

Built around DSE, TSA and HKAT.

Rubrics and marking models are designed by teachers who have graded the real exams — not generic AI tuned for US standards.

02

Data stays in your school

Each school on an isolated tenant. We never train AI on school data.

Every school gets its own data boundary. We do not train any model on student work, and we do not share data across schools.

03

Human-in-loop, not human-replaced

Teachers always review before students see it.

AI drafts the marking; the teacher confirms or edits. The platform exists to give teachers time back, not to remove them from the loop.
