Here, crudely, is how No Child Left Behind works. Unless a certain percentage of students score proficiently on standardized tests, a school receiving Title I federal aid will be placed on probation for several years. School officials will have to take extraordinary measures to improve scores, such offering additional tutoring. But if a school doesn't improve its test scores, it could ultimately be shut down, or have its entire staff fired and replaced. Last year, 25 percent of students had to score proficient or above in English. But this year, that number rose to 35 percent, and the East Bay's schools got hammered as a result. According to the Tribune, twelve new Oakland schools have been placed on probation. And according to the Chron, almost 1,400 schools statewide have been added to the "program improvement" list.
