The Road-STEAMer Horizon Europe Program examines STEAM (Science, Technology, Engineering, Arts, and Mathematics) education policies across Europe, with a specific focus on integrating the arts into traditional STEM disciplines. Through the analysis of open-access repositories, official documents, and stakeholder interviews, this study conducts both a macroanalysis of European policies and a detailed analysis of national initiatives. The research categorizes EU member states into three groups: high-priority countries (Belgium, France, Bulgaria, Finland, and Germany), countries acknowledging the importance of STEAM with partial initiatives, and those in early development stages. Special attention is given to grassroots initiatives. The findings reveal significant variation among member states and affiliated countries, driven by unique national challenges. In many cases, STEM/STEAM programs are closely linked to broader societal issues, such as financial development, digital transition, and social inequalities.
