Adequate Yearly Progress (AYP) and No Child Left Behind (NCLB)

Based on their MCAS results, districts and schools in Massachusetts are placed in one of five "accountability and assistance" levels.
Level 1 schools are the highest performing schools. Level 3 and 4 schools are in the bottom 20% in school performance. These schools receive additional supports. Level 5 schools are "chronically underperforming" schools. These have been taken over by the Mass. Department of Elementary & Secondary Education because they have not improved sufficiently even after receiving extensive resources.
