to help low-income minority parents choose schools with higher ratings. Debate over funding Nearly all charter schools face implementation obstacles, but newly created schools are most vulnerable. Some charter advocates claim that new charters tend to be plagued by resource limitations, particularly inadequate startup funds. Yet, a few charter schools also attract large amounts of interest and money from private sources such as the Gates Foundation, the Walton Family Foundation, the Broad Foundation, and the NewSchools Venture Fund. Private businesses and foundations, such as Ameritech and the Annenberg Fund, have provided financial support to some charters in assisting with start up costs for new schools. Although charter advocates recommend the schools control all per-pupil funds, charter advocates claim that their schools rarely receive as much funding as other public schools. Charter schools in California were guaranteed a set amount of district funding that in some districts amounted to $800 per student per year more than traditional public schools received until a new law was passed that took effect in fall 2006. Charter advocates claim that their schools generally lack access to funding for facilities and special program funds distributed on a district basis. Congress and the president allocated $80 million to support charter-school activities in fiscal year 1998, up from $51 million in 1997. Despite the possibility of additional private and non-district funding, a government study showed that charter school may still lag behind traditional public school achievement. Although charter schools receive less public funding than traditional public schools, a portion of charter schools' operating costs can come from sources outside public funding (such as private funding in the form of donations). A study funded by the American Federation of Teachers found that in DC charter schools, private funding accounted for $780 per pupil on average and, combined with a higher level of public funding in some charters (mostly due to non-district funding), resulted in considerably higher funding when compared to comparable public schools. Without federal funding, private funding, and "other income", D.C. charter schools received slightly more on average ($8,725 versus $8,676 per pupil), but that funding was more concentrated in the better funded charter schools (as seen by the median DC charter school funding of $7,940 per pupil). With federal, private, and "other income", charter school funding shot up to an average of $11,644 versus the district $10,384 per pupil. The median here showed an even more unequal
