Six years after Michelle Rhee rode into town, the public schools seem to be worse off by almost every conceivable measure.
For teachers, DCPS has become a revolving door. Half of all newly hired teachers (both rookies and experienced teachers) leave within two years; by contrast, the national average is understood to be between three and five years. Veterans haven’t stuck around either. After just two years of Rhee’s reforms, 33% of all teachers on the payroll departed; after 4 years, 52% left.
It has been a revolving door for principals as well. Ms. Rhee appointed 91 principals in her three years as chancellor, 39 of whom no longer held those jobs in August 2010. Some chose to leave; others, on one-year contracts, were fired for not producing quickly enough. Several schools are reported to have had three principals in three years. [...]
Ms. Rhee and her admirers point to increases on the National Assessment of Educational Progress, an exam given every two years to a sample of students under the tightest possible security. And while NAEP scores did go up, they rose in roughly the same amount as they had under her two immediate predecessors, and Washington remains at or near the bottom on that national measure.
The most disturbing effect of Ms. Rhee’s reform effort is the widening gap in academic performance between low-income and upper-income students, a meaningful statistic in Washington, where race and income are highly correlated. On the most recent NAEP test (2011) only about 10% of low-income students in grades 4 and 8 scored ‘proficient’ in reading and math. Since 2007, the performance gap has increased by 29 percentile points in 8th grade reading, by 44 in 4th grade reading, by 45 in 8th grade math, and by 72 in 4th grade math. Although these numbers are also influenced by changes in high- and low-income populations, the gaps are so extreme that is seems clear that low-income students, most of them African-American, generally did not fare well during Ms. Rhee’s time in Washington.
