In Greece, since 2015, when immigrant flows increased due to the crisis in Syria, there have been significant changes in school demographics, raising concerns as to whether in-service teachers possess the competences necessary to meet the upcoming challenges. We therefore investigated the views of Primary Education teachers, regarding their needs in intercultural education, and the parameters they deem important in implementing effective training interventions. The statistical analysis of the data revealed the necessity of implementing training interventions aligned with teachers’ individual needs, whilst there have been identified several issues regarding the existing training schemes, which demand serious consideration and further investigation.
