The Catalan autonomic Administration related with the consultation does not exercise competences in the educational area, but of representation of the Government and of cultural diffusion. Therefore, the requirements of identity of competences or matters that the article 21 of the LOPD requires to be able to carry out the cession without the consent of the headlines of the data are not given. It would be necessary to ask for the corresponding consents of the headlines of the particulars, or to use other informative mechanisms.
