Nearly three-fourths of registered D.C. voters support education reforms such as charter schools and private school vouchers, the same time as confidence in public schools Chancellor Michelle Rhee is inching up, according to a new survey.

The report, released jointly by eight Washington-area organizations that advocate shaking up the traditional public school system, partly reflects the growth seen in nonpublic education. Charter schools now enroll more than one-third of public school students, up 17 percent from 2008. The D.C. Opportunity Scholarship program, which has provided money for low-income students to attend private schools, has served more than 8,000 students since its start in 2001.
