Until now, however, researchers lacked nationwide data to prove it. That changed Wednesday when the Department of Education released a 78-page report.
Its conclusion: Tens of thousands of schools serving low-income students are being shortchanged because districts spend fewer state and local dollars on teacher salaries in those schools than on salaries in schools serving higher-income students.
“Low-income students need extra support and resources to succeed, but in far too many places, policies for assigning teachers and allocating resources are perpetuating the problem rather than solving it,” Secretary of Education Arne Duncan said in a conference call.
