Scaling digital assessment introduces new operational challenges. Variability in candidate experience, support demand, and processing timelines can quickly impact programme quality if not actively managed. This session explores how a global assessment programme implemented a data-driven monitoring framework to improve performance and maintain quality at scale. Drawing on real-world examples, attendees will learn how operational metrics, thresholds, and targeted interventions can be used to move from reactive troubleshooting to proactive programme management. Attendees will gain: • Practical approaches to defining and using programme health indicators. • Strategies for setting thresholds and triggering operational responses. • Insights into managing multilingual, global candidate populations. • Lessons from real interventions that improved SLA performance and reduced candidate friction.
