And yet, there are schools attended by the "lower classes" with much higher funding levels than private schools who rank as some of the worst in the nation.

According to a 2007 article in The Washington Post, the Washington D.C. public school district spends $12,979 per student per year. This is the third highest level of funding per student out of the 100 biggest school districts in the U.S. Despite this high level of funding, the school district has produced outcomes that are lower than the national average. In reading and math, the district's students score the lowest among 11 major school districts – even when poor children are compared with other poor children. 33% of poor fourth graders in the U.S. lack basic skills in math, but in Washington D.C., it's 62%.
