WASHINGTON (AP) — Chief state school officers are seeking to reassure the public that the new Common Core standards will not lead to the sharing of personally identifiable student data with the federal government.

Education officers from 35 states sent a letter Thursday to Education Secretary Arne Duncan addressing concerns that there will be new reporting requirements because of the standards. They said that won’t happen and that the federal government is prohibited from creating a student-level database with individual students’ test results. They said the states will continue to provide the Education Department with school-level data.
