South Africa’s education crisis  is complex, but key elements underpin many of the biggest challenges. UCT OHS’s innovative approach and use of technology addresses each element in a way that enables efficient and therefore affordable delivery of high quality education.Leveraging technology to scale high-quality teaching. By delineating, disaggregating and reconfiguring roles, teachers are able to focus on what they do best: teach. Administrative, socioemotional support and the bulk of content creation roles are separated. Student success mentors provide rich human engagement and are employed  to motivate learners, monitor their progress and link to remediation interventions if they fall behind.Data-driven education - we use advanced learning analytics, including powerful diagnostic assessments. If you can’t measure it, you can’t improve it.Mastery-based progression, individuated pacing and targeted remediation. Students master a concept before progressing to the next and move at a guided, flexible pace. Advanced remediation programmes address conceptual gaps from the outset.
