Mayor Adrian Fenty’s pick to run the D.C. Public Schools will be grilled today on whether she is up to the task of revamping one of the nation’s poorest-performing systems despite little classroom or large-scale management experience.

The D.C. Council is scheduled to hear testimony on Michelle Rhee’s qualifications to manage the day-to-day operations of a failing municipal school system. Several Council members have openly questioned whether Rhee, 37, has the background to oversee as chancellor such a massive operation, given that she taught in the classroom for only three years and led a nonprofit with fewer than 150 employees.
