The Technical Assistance for Nutrition (TAN) programme, funded with UK aid from the UK government, is a mechanism to provide technical assistance to Scaling Up Nutrition (SUN) country governments and build capacities towards advancing their multisectoral nutrition agendas, in line with the SUN Movement principles and roadmap. TAN also strives to generate, learn from, adopt and disseminate knowledge of what works within and across countries in the SUN Movement. TAN partners are the SUN Movement Secretariat (SMS), Maximising the Quality of Scaling up Nutrition Plus (MQSUN+), Nutrition International (NI), and the Emergency Nutrition Network (ENN). MQSUN+ and NI provide TA to SUN countries, while ENN provides knowledge management (KM) support to SUN countries, the TAN programme and SMS more broadly. MQSUN+ and NI TAN also support the SMS as needed.
