We propose a summer school for accelerator physics and technology, in particular intended for students from the northern part of Europe. The Nordic Particle Accelerator School 2015 (NPAS2015) will take place in Lund from August 17-21, 2015. The objective is to ensure future European accelerator expertise that can exploit, develop and improve current and future particle accelerators. The NPAS2015 aims to broaden the opportunities for education in accelerator physics and technology and to introduce students to the field of accelerator physics. Ultimately, we hope to encourage students to conduct their master's / Ph.D. project in accelerator physics. The school is organised by MAX IV Laboratory, European Spallation Source (ESS), Lund, Uppsala, Aarhus, Oslo and Jyväskylä Universities, together with a partnership of several European universities.
