Families In Schools has a lot of useful resources on its website, as well as writing the Education Advocacy Blog. Here’s how they describe themselves:

Families In Schools (FIS) was created in 2000 by the Los Angeles Annenberg Metropolitan Project (LAAMP) to continue the promising work initiated by the Annenberg Challenge in Los Angeles. The research by LAAMP and others on this subject confirms that when parents are engaged in the education of their children, performance on a variety of academic indicators significantly improves. In shaping the work of the organization, FIS was guided by Dr. Joyce Espstein and by Dr. Anne Henderson, two renowned experts in the field of parent involvement.

As the research bears out, there is a strong case for seeking parental involvement and engagement in the education process. Yet most educators need assistance and support in planning and implementing effective strategies and programs. To help them, FIS has created a “pathway to parent empowerment” that addresses the needs of parents from pre-k through 12th grade and provides programs, curriculum, and technical assistance at each level. Our programs and technical assistance are aimed at strengthening the capacity of schools, districts, and agencies who work with parents, as well as the capacity of parents by providing direct services to them through a variety of training opportunities.
