The objective of the Juan de la Cierva-incorporation grants is to promote the hiring of people with a doctorate degree by research organizations or Centros de I+D españoles for a period of three years in order to strengthen the skills acquired during a first stage of postdoctoral training. The aid, whose annual amount is 30,500 euros, is used to co-finance the salary and the Social Security business contribution of the people hired during each of the annuities. In addition to the above, an additional aid of 6,300 euros will be granted for each person hired, to cover the expenses directly related to the execution of the research activities of the person hired.
