What is "doctorandus"

n. (context historical in the Netherlands English) person who has passed an doctoral exam at a university, but has not yet attained a doctorate

Doctorandus , abbreviated drs., is a Dutch academic title according to the pre- Bachelor– Master system. The female form is 'doctoranda' (abbreviated dra., though this abbreviation is no longer used). The title is acquired by passing the doctoraalexamen, traditionally a matriculation exam for admission to study at doctoral level. In most cases this concludes university study, but occasionally students will continue to do research under the supervision of a professor, which eventually allows them to obtain the title of doctor.
