This Guidance Note provides detailed information on how and when to use the Diverse SOGIESC Rapid Assessment Tool package to facilitate assessment of diverse SOGIESC inclusion of programmes/projects implemented by humanitarian organizations. The tool uses a Survey instrument for collecting data from people with diverse SOGIESC, and spreadsheet-based Questionnaires and Dashboard for deriving a diverse SOGIESC inclusion score. The tool focuses on five key areas: Pre-emergency marginalization and gender analysis; Inclusion, partnership and leadership; Safety and protection; Shelter and housing; and Livelihoods and early recovery.
