"Since October 2017, the Common Service for Community Engagement and Accountability (‘the Common Service’) has been funded as a dedicated project providing key services and support to help humanitarian organisations engage effectively with Rohingya communities and Bangladeshis living near Rohingya camps (host communities) in Cox’s Bazar. A sub-national working group on communicating with communities (CwC) already existed in Bangladesh and was activated in response to the Rohingya refugee crisis. The Common Service project operates alongside the working group carrying out a diverse range of activities including creating and sharing audio and visual content in the Rohingya language; supporting and training humanitarian agencies on language, communication, community engagement and accountability; and operating a collective feedback analysis service, collating and analysing community feedback and complaints data from different sources and producing a fortnightly bulletin" (Preface, page 4). –- "There is strong evidence to suggest that community members have improved access to coordinated, timely and responsive two-way community engagement as a result of the Common Service. The evaluation has found causal evidence to suggest that support the Common Service has provided to the humanitarian sector, through provision of communication materials and training has led to humanitarian agencies being better equipped to communicate with communities and in turn community members having access to key, useful information which has prompted them to take action."
