As the world of work changes, UK pharmacists are increasingly required to recognise and articulate lifelong learning. College of Pharmacy Practice (CPP) portfolios were made available to 25 pharmacists in a single Workforce Development Confederation area. The evaluation reported here formed one strand of a larger study exploring CPD activity in the NHS. This strand aimed to describe and consider the ways in which pharmacists used the CPP portfolio as a vehicle to articulate their acquisition and use of practice based knowledge. Data were obtained through semi-structured interviews with nine pharmacists before and after using the portfolios (n = 18 interviews) and were analysed using "framework technique". Key emergent themes were "socialised learning" and "learning amplification", in particular the findings emphasised the importance of recognising:the advantages/disadvantages of work based (socialised) learning approaches; and the environment in which learning takes place and ensuring that learning can be "amplified" for the individual and the organisation.
