Science teachers in the England have always relied on the support of largely self-taught technicians when preparing classroom practicals. The technicians have acquired some of their expertise through ad hoc mentoring by senior colleagues, but very few have had any extended training. This research set out to explore the changing attitudes of 40 science technicians in the English East Midlands who attended four-day training courses during 2005. Their attitudes towards their current jobs and career as well as the effect of more formal training was explored by using pre- and post-course questionnaires along with in-depth interviews. Teachers who worked closely with them were also interviewed to gauge the impact of the training courses on the work of their departments. The study revealed that the courses increased most participants' job satisfaction and their confidence in their craft, but that training benefits could be compromised if communication with line managers was poor.
