From American Educational Research Association:

Aiming to investigate the impacts of No Child Left Behind (NCLB) on teachers’ perceptions of their work environments and job attitudes, this recent study (Grissom 2014) analyzed data from a nationally representative Schools and Staffing Survey. The survey was given every four years from 1994 to 2008 and the data was used to create a “cross-section” of teachers’ job satisfaction. Documenting overall trends in 140,000 teachers’ attitudes across this time period, the researchers examined state accountability systems and differences in likely impacts on schools to isolate NCLB effects.
