The backlog has persisted since the COVID-19 pandemic, and recovery has been slower than expected. As of late 2025, learners faced average waiting times of around 22 weeks, with many test centres hitting the maximum wait of 24 weeks.

One of the biggest impacts on instructors is the extended learning cycle. Pupils now continue lessons for months after reaching test standard because they cannot secure a test date.
This creates several knock-on effects:
