The Advocacy Institute supports social justice organizations to build the advocacy skills, knowledge and power they need to shape government policy for a more just and equitable New York.

We work with communities of color, immigrants, low-income people, LGBTQ+ people, and other underrepresented groups throughout New York City & State to provide them with the tools to fight for policy change more effectively. We offer dynamic trainings on the legislative process and interactive tools that map out power relationships in state and local government. We also engage organizations through a membership model where we provide 1-on-1 strategic consulting to help our members refine and reach their campaign goals.

Through our programming, we strengthen New York’s social justice ecosystem by supporting advocates to gain the skills, knowledge, and connections needed to build effective statewide coalitions that can win transformative legislative reforms. And we build a collaborative community to learn from and support each other’s work.

The Advocacy Institute was founded by Maggie Williams and James Schaffer in 2013. We began by designing and distributing maps that helped small social justice and grassroots organizations successfully understand local and state government structures, timelines and power relations.

We’ve since hosted a series of training and multi-week courses on advocacy for groups actively engaged in legislative campaigns. We’ve steadily developed our curriculum and community of speakers: government insiders, seasoned advocates, organizers and journalists.

Our goal remains to clarify government structures and relationships, as well as reveal who holds power, who works for them, and how they fit within a coherent, if opaque, landscape.

We’ve identified several opportunities to clarify complex information and preserve institutional knowledge. As a result, we committed to developing tools to address these scenarios.

Our Legislative Directory and Legislative Maps are resources that help organizers and advocates identify targets, strategize opportunities to influence legislation, schedule legislative meetings, track their relationships with elected officials and staff, as well as pool information with allies.

We’re deepening our collaborative networks by using a cohort model that develops trust across issue areas.

Meet the Team

The Advocacy Institute is a well-respected advocacy resource, trusted by progressive foundations, local and statewide coalitions, and grassroots organizations. With a community of government insiders, seasoned advocates, organizers and journalists, our team knows what resources are missing and what opportunities exist.

Woven into our cohort model is a commitment to developing collaborative networks, trust across issue areas, and an understanding of the dynamics of privilege and oppression in legislative advocacy. All this serves to build infrastructure that lasts from one campaign to the next and helps shift the balance of power.
