The sub-programme led to the creation of 1327 minicompanies from 2009 to 2014, but a critical research question complementing these results is: how effective is the entrepreneur training sub-programme? A qualitative and quantitative assessment of the sub-programme demonstrated the critical role of tutors (teachers) and advisors, and revealed a significant improvement in the administrative knowledge and entrepreneurial skills of participants, along with a reinforcement of business values. © 2017 The Authorsinfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-nd/4.07 INGENIERÍA Y TECNOLOGÍADeveloping entrepreneurship in primary schools.
