Assignment review Copilot Agent: Giving teachers time back

At OneSchool Global, we’re using AI to help teachers focus on what matters most – supporting students.

In partnership with Engage Squared and using Microsoft Copilot, our Assignment Review Copilot Agent is transforming how educators review and quality‑assure student work across our 120+ campuses worldwide.

What once took up to an hour per Assignment can now be completed in around 15 minutes, delivering a 75% efficiency gain and freeing teachers to spend more time teaching.

• 375 days of time back to teachers – more than 3,000 hours redirected to student learning and support
• 90% accuracy, with educators maintaining full oversight and personalisation of every review
• Improved visibility of assignment quality, enabling targeted training and continuous improvement

Anat Hassner, Global COO said: “The Assignment Review Agent is an example of how we’re using custom-built AI tools to drive high performance and improve student and campus outcomes. As part of our broader AI roadmap, we’re helping educators work more effectively so they can spend more time teaching, supporting students and helping them become lifelong learners.”

The next phase is already underway – and AI‑guided Assignment Design Agent – extending the benefits across the full assignment lifecycle and strengthening our digital curriculum for students globally.
