As a postgraduate researcher you will develop a range of skills and specific academic knowledge. Your core transferable skills (i.e. communication and presentation) are likely to be higher than that of a graduate student. You are likely to be able to work independently with the need for minimal supervision and be capable of critical thinking. The Research Development Framework (RDF) provides a summary of the skills a PGR should develop during their studies. It is your responsibility to take ownership for your career by nurturing these skills and demonstrating these to potential future employers.
The dictionary definition of skill is "the ability, coming from one's knowledge, practice, aptitude, etc., to do something well" (www.dictionary.com). Broadly speaking a skill is the ability to do something well with minimal time and with minimal effort. The development of a skill requires cyclic repetition of performing, reflection, conceptualisation and experimentation. Through this cyclic nature the eventual proficiency is increased. It is important to note that without informed feedback, through reflection and conceptualisation, repetition will potentially serve to reinforce bad habits.
We would suggest that in order to develop you must first understand the skills you possess and be able to evidence these. The section on identifying your skills provides examples of how best to do this by utilising a skills audit and personal development plan.
