Only 37 percent of tested students in District of Columbia Public Schools and the city's public charter schools earned proficient or advanced rankings in reading in 2007, and only 32 percent reached those levels in math, Jennifer Comey told the city council. However, between 2006 and 2007, the share of all public school students testing proficient or advanced increased. In 2007, public charter school students tested slightly higher on average compared with DCPS students.
