The Dual Mention in official university education is a common training project that is developed complementarily in the university centre and in a collaborating entity, which may be a company, a social or trade union organisation, an institution or an administration, under the supervision and training leadership of the university centre, and whose objective is the appropriate training of students to improve their comprehensive training and improve their employability.
The dual training activity is carried out through an alternating training contract, where the worker alternates training with work in the company.
