This Handbook describes the development and implementation of one training programme for students developed by UTAD during the spring of 2022 and implemented during the fall of the same year. The programme development was mainly based in the three HEI’s experience with entrepreneurship formal education and in a survey identifying students’ major competence gaps. Survey results suggested that, over and above developing business ideas, students needed training in knowledge commercialization, marketing, and financial issues. The programme, named “Boost Your Startup Idea!” to deliver the message that it could boost the process of transforming an idea into a startup, was framed into three consecutive phases: developing the idea (desirable); defining a strategy (doable); assess return (profitable). Teams of trainees developed 12 sustainable business ideas, three of which have been awarded prizes in contests. Despite these good results, the ETEIA team identified some ways of improving the programme to achieve better results, not only in the generation of good ideas, but also in students’ intention to start-up a business. The action plan for improvement is a proposal of a new programme, including all the contents of the original and extending its duration to add four additional modules, focusing on negotiation and communication, as well as on the positive (bright side) and negative (dark-side and downside) expected outcomes of the entrepreneurial activity. The proposal names the programme “Leading Entrepreneurs to Act”, signalling the ambition to foster students’ self-efficacy to act as nascent entrepreneurs. The objective is to have more students attracted by the bright side of an entrepreneurial career and subsequently increase their confidence to cope with the suffering from the dark-side and to attenuate the losses from the downside.
