It has educational links with schools in Dithmarchen, Germany, notably the Gymnasium Heide-Ost.

It has also had links with Collège des Quatre Vents in Lanmeur, Brittany, France.

In 2007, Poltair School held its centenary, which included guided tours of the school, a service at St John's Methodist Church, and celebrations at St Austell's Eden Project.

In September 2019 Poltair School converted to academy status and is now sponsored by the Cornwall Education & Learning Trust.

However its GCSE pass rate is well below the England average, and the second lowest in Cornwall (above Redruth School).
