Due to the popularity and broad-ranging nature of the discipline, psychology students will face particularly fierce competition throughout their careers and must be acutely aware of the need to produce publishable, fundable, and impactful work. Given these pressures on PhD students and their supervisors, does teaching during postgraduate study give worthwhile experience, or is it a needless tax on time that is both limited and strained?
