Universiteit Leiden — WO graduate counts

Original DUO main-diploma observations in the combined higher education domain, with the source's 1 October reference convention. DIPLOMAJAAR is the original diploma-year code, not an admission year or website update year. The source selects main associate-degree, bachelor, master, doctoral and professional/postmaster diplomas as specified in its definitions; propaedeutic diplomas, post-initial diplomas and exchange-student diplomas are excluded. These are diploma-domain counts, not a graduation probability or the outcome of an admission cohort. The catalogue introduction also refers to enrolments; CollegeVerse retains that original metadata while using the explicit graduate selection and AANTAL_GEDIPLOMEERDEN field.

INSTELLINGSCODE_ACTUEEL and INSTELLINGSNAAM_ACTUEEL are current identifiers and labels applied in the source; these tables do not reconstruct historical institutional boundaries. Original municipality, qualification, field/subfield and gender categories remain distinct. No counts are summed into invented university totals or mapped to CIP. ONBEKEND is retained as an unknown source category, not redistributed.

Source marker caution: the catalogue describes replacing original values 1-4 by 4, while the current extract contains -1. CollegeVerse retains -1 as an uninterpreted source marker, not a negative count, zero, exact suppressed number or inferred range. A source value of 4 is displayed as a filtered range according to the catalogue. No ratios or totals are calculated from these cells.
