 Case studies and best practices show that complying with the CHS indeed increases the overall effectiveness and quality of the work of humanitarian and development organisations.For example, putting emphasis on training (Commitment 7, 8) helps to improve the quality and speed of surge response, improving the way of engagement with communities (Commitment 4) helps to obtain quality information and thus a true understanding of people’s realities, and in general, the CHS contributes to making organisations more transparent and to addressing sexual exploitation and abuse (SEA).The Core Humanitarian Standard (CHS) is a voluntary and measurable standard, which means its application can be objectively assessed.
