Retention of engineering students

Retention of engineering students is an international concern. Most countries report a shortage of engineers. By increasing the number of retained engineering students it is potentially possible to increase the number of engineering graduates. The purpose of this article is to identify and analyse what retention research has been done in the past to avoid unnecessary duplication. Although duplication may bring valuable new information, progress in this field has been slow. Therefore, the focus is on facilitating progress rather than seeking more accurate results. The three main themes identified in literature are: the individual's internal and external characteristics that affect retention, the models that describe retention, conceptual and predictive, and the interventions attempted to improve retention. Further research into methods for improving student retention is certainly justified since in spite of existing research most institutions still struggle to retain engineering students.
