Why is there an ECTS grading table on my diploma supplement?

In 2016,  Dutch universities agreed to introduce the ECTS grading table at a national level, to give international institutes and employers greater insight into the value of Dutch grades. The grading table also facilitates the comparison of a student’s grades with those of his or her classmates. In accordance with this agreement, Leiden University prints an ECTS grading table on all diploma supplements and transcripts of records.
