Quality assurance of the practical endorsement is carried out by visiting monitors.
For Biology, Chemistry and Physics, your centre will be monitored at least once during every two-year cycle, with that visit usually limited to one subject. Large centres (more than 140 entries for any subject) will be monitored for all sciences.
A Level Geology is monitored separately and a visit is required in every two-year cycle.
The monitor who visits will be appointed by the awarding organisation with which your centre has registered for the science selected for the visit.
Monitoring ensures the common practical assessment criteria are being correctly applied, and that procedures and records are being implemented and maintained in order to meet the requirements of the practical endorsement.
