Question regarding documents

Hi,

I am on the reserve list for a traineeship in the General Secretariat of the European Parliament. They asked to me to sent these documents:

· scanned copy of the printed on-line application form, duly dated and signed ;

• scanned copy of an identity document indicating your nationality ;

• scanned copy of your university diploma(s) ;

• scanned copy of an accreditation card or published articles (for journalism option only);

Can You confirm me that the last point is only for the journalism option? Or the advice is regarding only published articles and not for the accreditation?

Thank you!
