I only use research results that have been checked and approved by the Databank for data protection purposes.

I acknowledge that the publishability of research results for data protection purposes is affected by the content of the research results already exported in the context of that research.

With regard to the data provided, I make no attempt to identify, disclose or communicate specific information about the statistical units in the files. This responsibility shall survive the termination of access to the data.

I acknowledge that I am liable to civil, criminal and labour law penalties in the event of any breach of the rules governing the use of the data file to which access is granted.

I declare that I am familiar with the research project objectives stated on the Application Form and that I will only carry out activities that are in line with the objectives stated therein.

I acknowledge that if I use the data made available in this agreement in the context of a BCE course, it may not be used for publication in the electronic or printed press, and the results of the publication may only be used in connection with the course.

If a publication is produced using the data made available under the agreement, the project leader must be listed as co-author, unless the student is required to list the work as a separate publication.

If the data made available under the agreement is used for a BCE course given by a BCE employee, it may not be used for any publication in the electronic or printed press, and the results of the publication may only be used in connection with the course. The student agrees to this in a declaration. In the case of such access, the CERS Databank will provide a reduced set of variables and number of cases, which will be produced in a manner appropriate to the research purpose. Data reduction aims to reduce the risk of discovery and the load on the server.

The data produced as output must be consistent with the purposes stated in writing by the project leader on the project start-up form, failing which access to the data may be restricted or the release of the data may be refused by the CERS Databank.
