The D.C. Council is poised to vote Tuesday on legislation that would lead to a massive transformation in District schools — changing everything from where teachers work and how they are paid, to which tests high schoolers must take to graduate.

The “Raising the Expectations for Education Outcomes Act of 2012” sews together four education bills of varying levels of controversy into a single piece of legislation. Three of the bills were introduced by Chairman Kwame Brown, and a widely supported plan to transform several D.C. schools into community hubs was sponsored by Brown, At-large Councilman Michael Brown and Ward 1 Councilman Jim Graham.
