The honors work consists of two years of 15 credits each. After the first year you are assessed on the progress you have made so far, and on the quality of your work and output. This is also a second moment of (self) selection. You can decide not to go on with the second year of the honors program or to do this second year in a different Track. Your assessors, too, may decide that you cannot enter the second year. If you only complete the first year successfully you can request for a certificate (webform).
The second year of the honors work is also concluded with an end-of-year assessment, which will address your development and the quality of the work you have delivered. Successful completion of both the first and the second year of the honors program will be mentioned on your Bachelor Degree diploma at your own department. In addition, you will receive a letter of recommendation together with your Bachelor Degree diploma.
The successful completion of both honors years and the letter of recommendation may give you a head start when you apply for a scholarship or for a position at a prestigious Master program in the Netherlands or abroad.
