The 2014 General Assembly of ECHA agreed that ECHA will support, regulate and guide the formation of a European Talent Support Network. European Talent Centres will form the hubs of this Network, while European Talent Points will be its nodes.
Aims and details of the European Talent Support Network can be found in the document downloadable from: https://echa.info/images/documents/high-ability/European-Talent-Support-Network-ECHA-General-Assembly.pdf
The General Assembly of ECHA elected the Qualification Committee in 2016: https://www.echa.info/qualification-committee to qualify European Talent Centres.
The Qualification Committee invites European or in case of Associated Centres non European talent support organisations to submit their application to become a European or Associated European Talent Centre.
A European Talent Centre should be an organisation, or a distinct part of a larger organisation, established for this role. European Talent Centres might organise activities in the field of high ability in a region or a country (meaning that there might be more than one European Talent Centre per European country, and applications may cover more than one country).
You can read about the results of the first round (2015) and the second round (2016) of applications here: https://www.echa.info/129-breaking-news-the-first-14-european-talent-centres and here: https://www.echa.info/170-five-new-centres-in-the-european-talent-support-network
You can only apply on-line on the ETSN website (https://etsn.eu/apply-to-become-a-talent-centre/); the application form in a pdf format and its scoring sheet can be downloaded from here, too. The Qualification Committee will evaluate your application by aggregating the scores as a whole. Applications will not be judged against each criteria separately. Successful proven past activity and potential future engagements in the field would be of key importance in this process.
Existing European Talent Centres will be re-evaluated every other year (i.e. in 2019, 2021 etc.) by the Qualification Committee of ECHA to ensure that they still fulfil the criteria. If the criteria are no longer fulfilled, the title of European Talent Centre may be suspended or withdrawn by the Committee.
 The notion of hubs (Talent Centres) and nodes (Talent Points) in the forming European Talent Support Network does not mean a hierarchical structure. European Talent Points will be linked to the Network through European Talent Centres. European Talent Points may also develop contacts with multiple European Talent Centres and each other. Talent Centers should be considered as coordinating centers. There is a possibility for a joint-application to be a European Talent Centre requiring no potential European Talent Points (schools, parent organisations, organisations in gifted education, etc.) for that particular Centre. That gives a way to make a fully non-hierarchical network in countries, or regions, where it is preferred.
