D.C. Charter School Rankings Show 20 Schools 'High Performing'

For the second year, the D.C. public charter school board released its internal school performance rankings. The performance management framework, which measures a variety of factors including attendance, improvement in test scores and re-enrollment rates, is meant to be an easy guide to monitoring a school's performance. 

Twenty D.C. charter schools have been ranked Tier 1 schools, meaning they received a score of more than 65 percent on a variety of these metrics. They're considered high performing schools. A total of 35 schools made Tier 2, meaning they met minimum standards.  

Nine schools are ranked Tier 3, scoring below 35 percent. If a school is ranked Tier 3 for three years, it may be closed. The charter school system has 57 schools on 102 campuses.

D.C. Prep remains the top ranked public charter school in D.C. overall two years in a row. Washington Latin has the highest re-enrollment rate and the highest graduation rate. The full list of rankings is available on the charter school board's website.
