ADMINISTRATION UNVEILS 'NO CHILD' REWRITE - POLITICO's Nia-Malika Henderson: 'President Barack Obama unveiled his plan for a sweeping overhaul of the nation's school system Saturday, proposing changes he says would shift emphasis from teaching to the test to a more nuanced assessment of judging school and student progress. On Monday, Obama will submit his blueprint for reauthorizing the No Child Left Behind law to Congress, and he's given lawmakers a powerful incentive to take up the bill this year-his budget proposal includes a $1 billion bonus should new legislation land on his desk this year. Obama's proposal would toss out the core of the Bush-era law, which calls for across-the-board proficiency from all students in reading and math by 2014, and instead emphasize revamped assessment tools that link teacher evaluations to student progress, and a goal of having students career and college ready upon graduation. ... The blueprint is 'not only a plan to renovate a flawed law, but also an outline for a re-envisioned federal role in education,' Obama writes in the introduction to the 45-page document released Saturday evening. Under the proposed guidelines, the nation's 100,000 schools would be divided into categories, based on how well their students are performing based on annual tests. Low-performing schools would require state intervention, and could face a complete shutdown. ... Among the changes are a greater emphasis on evaluating teachers more rigorously, including rolling back seniority, implementing merit pay and allowing districts greater flexibility in assigning students.'
