The Accountability Plateau.

After more than ten years under NCLB, that law's legacy continues to be fiercely contested. This analysis of NAEP scores -- focusing on Texas and on the entire nation -- by former NCES commissioner Mark Schneider finds that solid gains in math achievement coincided with the advent of "consequential accountability," first in the trailblazing Lone Star State and a few other pioneer states, then across the land with the implementation of NCLB. But Schneider warns that the recent plateau in Texas math scores may foreshadow a coming stagnation in the country's performance. Has the testing-and-accountability movement as we know it run out of steam? How else might we rekindle our nation's education progress?
