Data collection

Data on gender, curricular phase when the referral was made, and nationality of the referred students were collected from the student administration desk. As only the country of birth of the students is registered, students were classified as non-Dutch if the official language of the country of birth on record was a language other than Dutch.

Data on the reasons for referral and the number of referrals per student were collected from referral letters and professional behaviour board dossiers.

In order to compare the referred students with the total student population, data on gender, nationality and phase in the curriculum of the total student population were also collected from the student administration desk.
