Investigator training: Sexual Exploitation, Abuse and Harassment (SEAH)
Sexual exploitation, abuse and harassment continue to be a pervasive and devastating issue within international humanitarian and development efforts.
A key approach to addressing SEAH is training professionals from civil society organisations, UN agencies, peacekeeping personnel and national government stakeholders in how to identify, report, and investigate incidents in a professional, survivor-centred and trauma-informed manner.
OSACO offers a four-day intensive training on investigating cases of SEAH with a focus on survivor-centred and trauma-informed approaches.
Prior to the four-day training, participants will go through an e-learning course outlining the key aspects of an SEAH investigation. Participants will be provided with pre-reading materials. In the four-day training we move from theory to practice.
During the in-person training you will conduct a SEAH investigation with a case study relevant to your context and scope of operation. We will dedicate two days to role-plays in which you can learn, within a safe space, to conduct investigative interviews. You will receive constructive feedback sessions after each interview.
