This report summarizes the pre-training preparatory field visit to Nambale and Nyando Districts that took place on November 29 and 30, and the training work done at the Morendat Training Centre in Naivasha from December 3 to December 6. The training revolved around Cristina Bicchieri’s account of social norms (cf. her The Grammar of Society, Cambridge University Press, 2005.) The main aim of the training was to show how the Community Led Total Sanitation (CLTS) approach to eradicate open defecation and Social Norm Theory (SNT) can be readily harmonized and how elements of CLTS can be better understood when looked at through the lens of SNT.
