This study draws upon two sources of data: an online survey and telephone interviews. In spring 2012, GFE selected 138 grantmaking organizations to participate in an online survey. The sample was composed primarily of GFE members who had indicated in GFE's 2010 and 2011 benchmarking surveys that they made grants to English learners or immigrants, but it was supplemented with funders identified as significant investors in English learners by Grantmakers for Children, Youth and Families and Grantmakers Concerned with Immigrants and Refugees. Fifty-seven grantmakers completed responses to the survey, representing diverse grantmaking entities including family foundations, private foundations, community foundations and corporate funders. Researchers supplemented the survey by conducting in-depth phone interviews with 24 survey respondents selected to represent a range of foundation sizes, organization types, geographic regions and ELL funding priorities. The study also convened an Advisory Committee comprising GFE members who are experienced funders of English learners. The advisory committee offered advice on research design, interpretation of research findings, and supplemental resources (listed in report appendix).
