Sponsors who carry out or arrange for the carrying out of employment promotion measures (e.g. introduction to self-employment) themselves require approval. This applies regardless of whether they want to participate in tenders or offer voucher measures. The specific measure (e.g. founder coaching), on the other hand, only needs to be approved if it can be taken up with a voucher – i.e. with an education voucher or an activation and placement voucher. So-called expert bodies, which in turn have certification from the German Accreditation Body and operate on the basis of a private-law agreement with the labor market service provider, are responsible for approving providers and measures. The subject of this agreement is also the price for the accreditation. The expert body checks whether the requirements for accreditation according to §§ 176 ff. of the Third Book of the Social Code and the Accreditation and Approval Regulation for Employment Promotion (AZAV) are met. Approval can be granted for a maximum of five years.
