Eligibility criteria are important elements in award procedures for the selection of a bidder. Public clients efficiently and easily check the suitability of bidders using the ANKÖ list of suitable contractors. With the Once-Only database, you benefit from the fact that entrepreneurs can keep their qualifications up to date easily and without great effort. On the other hand, you can use automatic interfaces and thus receive up-to-date proofs at the push of a button.

You would like to use the ANKÖ for the aptitude test? Do you have questions about the exam or the database? We are at your disposal.
