STEM Identities
The campaign ran from 1 February to 30 April 2023, with a peak of activities from 24-30 April.

This campaign was a record-breaking success. More than 360,000 teachers and students worked hard between February and April 2023 to put their schools on the map and showcase their STEM activities.
