geprüften

Geprüften is the inflected form of the German past participle geprüft, derived from prüfen. It functions as an adjective indicating that something has undergone testing or certification by an authority. The form commonly appears in attributive position in noun phrases such as den geprüften Ingenieur, die geprüften Unterlagen or mit den geprüften Unterlagen.

Grammatically, geprüften is the attributive form used after definite articles and other determiners; its ending -en occurs in certain cases, such as plural nouns or in masculine accusative singular after definite articles. With indefinite articles, other endings apply: einen geprüften Techniker, eine geprüfte Technikerin, ein geprüftes Dokument. The participle can also be nominalized in certain contexts, especially in titles for certified individuals (Geprüfter Techniker, Geprüfte Fachkraft).

Usage contexts include professional qualifications, product quality, and document verification. For example, Die geprüften Unterlagen wurden eingereicht demonstrates that the documents have undergone official verification. In job adverts one may encounter Wir suchen einen geprüften Sicherheitstechniker, meaning a certified technician is sought. The distinction between geprüft and geprüften lies largely in grammatical case, gender, and number rather than in meaning; both convey testing or certification when used appropriately.
