A group of state school officials said new Common Core standards won't put students' privacy at risk.
Forty-five states recently adopted the standards, which supporters say will help align all states under a uniform goal and prepare children to compete in a global economy.
Critics contend the Common Core curriculum strips away local control and would let the federal government track the private test records of school children.
Education officers from 35 states signed a letter addressing those concerns.
The officers said the law forbids the government from creating student-level databases with individual test results and they'll provide only school-level data.
