This plan was structured around five key elements: (i) its relevance for teacher career progression, being free of charge and open to educators of all school subjects; (ii) an inquiry-based learning design, grounded in the most updated scientific knowledge and methods; (iii) a direct alignment with the school curriculum; (iv) the use Astronomy as a vehicle for interdisciplinary learning across several school subjects; and (v) a commitment to democratizing science leveraging the school system\u2019s multiplier effect. In this article, we present the different stages in the development of the TTP, which include institutional partnership with NASE (Network for Astronomy School Education) and EAAE (European Association for Astronomy Education). The program enrolled 3,208 teachers from all the Portuguese districts as well as from the Community of Portuguese Speaking Countries (CPLP). The PP-CCV\u2019s TTP, practical and replicable, proved to be an effective channel for bringing cutting-edge scientific knowledge and practices to educational contexts \u2013 especially in communities with historically low engagement with science, not by choice, but due to systemic barriers in access to scientific education.<\/jats:p>","DOI":"10.1515\/astro-2025-0019","type":"journal-article","created":{"date-parts":[[2025,10,24]],"date-time":"2025-10-24T01:54:27Z","timestamp":1761270867000},"source":"Crossref","is-referenced-by-count":1,"title":["Democratizing Astronomy through teacher training in Portuguese-speaking contexts"],"prefix":"10.1515","volume":"34","author":[{"given":"Il\u00eddio Andr\u00e9","family":"Costa","sequence":"first","affiliation":[{"name":"Santa B\u00e1rbara School Cluster\/Porto Planetarium \u2013 Ci\u00eancia Viva Center \/ Institute of Astrophysics and Space Sciences \u2013 University of Porto , Rua das Estrelas, 4150-762 , Porto , Portugal"},{"name":"CIQUP - IMS, Science Teaching Unity, University of Porto , Rua do Campo Alegre, 687 , 4169-007 Porto , Portugal"}]},{"given":"Carla","family":"Morais","sequence":"additional","affiliation":[{"name":"CIQUP - IMS, Science Teaching Unity, University of Porto , Rua do Campo Alegre, 687 , 4169-007 Porto , Portugal"}]},{"given":"Teresa","family":"Aguiar","sequence":"additional","affiliation":[{"name":"Research Centre in Chemistry, Institute of Molecular Sciences , Rua do Campo Alegre, 687 , 4169-007 Porto , Portugal"},{"name":"Centre for English, Translation, and Anglo-Portuguese Studies, University of Porto , Via Panor\u00e2mica, s\/n 4150-564 , Porto , Portugal"}]},{"given":"Adriana","family":"Silva","sequence":"additional","affiliation":[{"name":"Porto Planetarium \u2013 Ci\u00eancia Viva Center \/ Institute of Astrophysics and Space Sciences \u2013 University of Porto , Rua das Estrelas, 4150-762 , Porto , Portugal"}]}],"member":"374","published-online":{"date-parts":[[2025,10,23]]},"reference":[{"key":"2025122008261734074_j_astro-2025-0019_ref_001","doi-asserted-by":"crossref","unstructured":"Alves-Brito A, Spinelli PF, Cuambe VA, Cabral I, Latas J, Doran R. 2019.
