Leiden University offers 5 specialisations of a MSc programme in Mathematics. Two of these correspond to research specialisations in the Leiden Mathematical Institute. All specialisations are 2 years in duration (120EC). Students who complete the master will receive the degree Master of Science in Mathematics, with specification of the specialisation. Furthermore, all specialisations have the same director, the same Board of Examiners, and the same Department Teaching Committee, and the same Board of Admissions. The admission guidelines can vary per specialisation. For details, see your specialisation of choice. The admission process may include an interview with the Board of Admissions. Foreign applicants must provide proof of proficiency in English (IELTS level 6.5). Admission is possible throughout the year, but we advise foreign students to start in September or February.
