The aim of this research is to explore the impact of intercultural Mobility (learning by leaving) as a pedogogic tool in the learning environment and to undertake a return on investment analysis to measure the impact intercultural Mobility and work based learning has on absenteeism; academic performance; access, transfer & progression and employability. In my opinion, the value that an intercultural mobility work placement brings to the learning environment has not been researched in a significant measurable way and any tangible value that is evidenced is often buried in the bureaucracy of the Programme. Using a mixed methodological approach of both qualitative and quantitative enquiry the study explores the phenomenon of learner mobility as a pedagogic tool. Using the eight key competences plus identified transversal skills established by the European Commission in addition to the Irish Further Education and Training Awards Council (FETAC) identified core skills, key competences / specific learning outcomes (SLO’s) the study measures learner skills, knowledge and personal competences prior to and post a workplacement training intervention the study explores the impact learner mobility has on the learning environment in terms of the key competencies and skills required of citizens contributing to the European Communities knowledge based and globalised economy: the ability to learn and acquire new skills; adaptability; flexibility; information technology and entrepreneurship. Using Kirkpatrick’s four stages of learning/training evaluation theory (1967) and Phillips (1996) return on investment (ROI) model (Table 1.1) the study captures and isolates the benefit learner mobility and work based learning has on the micro education management key indicators of absenteeism, grades, access progression, transfer and emp
