The PCST conference attracts a substantial number of science communication academics and practitioners from all over the world. The conference is stimulating and refreshing but the size of it means that quality control is challenging for the organisers. This review highlights areas of both strengths and weaknesses whilst also making recommendations to the PCST committee for PCST 2016. The committee are encouraged to further strengthen the academic/practitioner combination and the international nature of the event. However, they are also recommended to ensure that work presented is of high quality with clear purposes and strong evaluative evidence presented.
