No Child Left -- Wait, hold on!

The No Child Left Behind Act, started during the Bush era, is taking an overhauling now that Obama is president. The old act required teachers to teach according to a test, forcing them to narrow the curriculum. Instead of this pass-fail system the new plan is to measure academic achievement on the individual scale. This new bill would also require government intervention to help out, while top achieving schools would get incentives. It would also put pressure on schools to reach 'college-and-career readiness' for its students.
Although this is bill has been worked out in a bipartisan way, there are still many critics of it, such as the two major teaching unions. They're both unhappy with the way the bill is shaping out, especially because it is leaving all of the responsibility on the teachers to reform things, without giving them any power to do so.
Even if this bill is brought to Congress this year, I wonder if they'll really be able to be bipartisan about it, or if this will be just another battle of the parties. This bill is requiring a major change in the education system that I doubt will just be passed in an easy manor. What also concerns me is, even if this bill is passed, what if Obama is out of the White House in 4 years and we have a Republican in office? Will the whole system be swapped back for the original No Child Left Behind?
