This integrative literature review aims to provide a broader and updated perspective of teachers’ intergenerational learning (IL). The search was done in Web of Science and EBSCO ultimate  databases between 2011 and 2022. Thirty-two empirical studies were selected and submitted to a thematic analysis and five themes were identified: (a) defining and conceptualising generation, (b) IL from understandings to practices, (c) contexts, factors and roles from different generations and institutions to promote IL, (d) factors that facilitate the success of IL, and (e) factors that make IL difficult. Data shows an increase in the last decades of research in IL within the educational context, but an absence of the prospective dimension still prevails. Intergenerational knowledge has been researched mainly from an individual professional perspective at the micro and meso levels of scholarship. Effectiveness requires intentional cultivation and a genuine desire for intergenerational knowledge exchange, involving active engagement and awareness among diverse generations and alignment with organizational aims. The promotion of IL takes place in very different ways and forms, and reflection on what is different seems to be a dominant trait. Furthermore, the review could conclude that intergenerational opportunities to work together will improve teacher education and continuous professional development.
