To be considered for admission to the TRAIL+ programme at the World Trade Institute, you are required to have completed a degree in law (licentiate or master's degree), or have a degree that is deemed equivalent, i.e. a degree in law which entitles you to sit for the bar exam or equivalent in your country of origin.

To apply for the TRAIL+ and for a detailed list of requirements, please use our online application form.

English language requirements:
The TRAIL+ is taught exclusively in English. Therefore, you must arrive at the WTI and the University of Bern with a level of English that allows you to fully benefit from the courses. In particular, your level of English needs to allow you to express yourself effectively in and outside the classroom, deliver on weekly writing assignments and adequately cover a weekly reading load of up to 200 pages.

When evaluating your application, the selection committee pays close attention to evidence of your proficiency in English. As is common for graduate programmes, you are required to submit objective test scores of one of the accepted tests listed below:

Test                          Minimum Score  
TOEFL ibT                100 points or above   

TOEFL Paper           600 points or above   

IELTS                       7.0 or above   

Cambridge CAE        A    

Cambridge CPE        C or higher   

The following applicants are exempt from submitting test scores:

  • Native English speakers
  • Students with an undergraduate and/or graduate degree from an institution in the USA, Canada, the UK, Ireland, Australia or New Zealand, where English was the primary language of instruction and the degree was awarded no longer than five years ago.

You may be exempt from submitting test scores if you are:

  • A student with an undergraduate and/or graduate degree from an institution where English was the primary language of instruction and the degree was awarded no longer than five years ago
  • A student who has completed at least one year of study in an English speaking country and at an institution where English was the primary language of instruction immediately prior to joining the TRAIL+ programme.

Please contact us if you are unsure of your exemption status. We will be glad to help. However, please be advised that exemptions from the language requirement are rarely granted. Important: If you believe you are exempt from a English test score, please add this to the comment box in the online application form.
