Our main goal in implementing this Erasmus+ project was to offer our students the opportunity to take part in a long-term mobility abroad as part of their vocational training. We aimed to give them the chance to discover different working methods, acquire new technical skills in their field, strengthen their autonomy, and develop their ability to adapt in an international professional environment. The project also intended to enhance language learning—especially Spanish—through full linguistic immersion, and to foster cultural awareness. Our aim was to offer a rewarding experience on all levels: personal, linguistic, professional, and cultural. Finally, this first long-term mobility marked an important step for our school. It is part of a broader objective to internationalise our training programme, by strengthening connections with high-quality European partners and laying the groundwork for future similar projects.
