The ILO Participatory Gender Audit (PGA) is a powerful tool for introducing and managing institutional change. It is a participatory method of promoting institutional learning and reinforcing organization's collective capacity to analyse its activities from a gender perspective, verifying its achievements and its challenges. The PGA Certification Programme is a transformative learning process that yields knowledge, techniques and tools to certify gender-sensitive analytical skills. The ultimate goal is to raise institutional awareness on gender issues to promote a change in attitudes and behaviour from within.
