Fifteen states and the District of Columbia have submitted plans for implementing the Every Student Succeeds Act. But only four of those plans—the ones from Connecticut, Delaware, Nevada, and New Mexico—have been deemed complete and submitted for “peer review” according to the U.S. Department of Education‘s website.

UPDATE: Vermont and Louisiana officials wrote in to tell us they received letters from the department saying their plans are complete.

As we wrote last month, some states, including Maine and Massachusetts, turned in plans with some information still yet-to-be-determined. Both states were waiting for baseline test information from new assessments before setting an overall student achievement goal. Both Maine and Massachusetts have already heard from the department.

It’s not clear if all twelve plans that haven’t yet been submitted for peer review have similar problems, or if the department is just still trying to check the boxes for completion.
