The Obama administration on Thursday afternoon said it will waive the cornerstone requirements of the No Child Left Behind Act, including the 2014 deadline that all students be proficient in math and language arts, and will give states the freedom to set their own student-achievement goals, and design their own interventions for failing schools.

In exchange for this flexibility, the administration will require states to adopt college- and career-ready standards, focus on 15 percent of their most-troubled schools, and create guidelines for teacher evaluations based in part on student performance.
