In France, access to some educational institutions is allowed only after a competitive examination. However, for special achievements, some students may be offered a seat directly, bypassing the examination altogether.
The French idiom is to have been selected “sur dossier” (“on file”). That is, your (implicitly: school) file was convincing enough to exempt you from the examination.
Is there any way to express this in English? If there are disparities between English-speaking countries, please specify them :)
