The public service workers who have had debt canceled include social workers, teachers, first responders and service members, the Education Department said.

The Biden administration announced a milestone Thursday in its effort to cancel Americans’ student debt: It has provided relief to more than 1 million borrowers who work in public service.

Through the Education Department’s Public Service Loan Forgiveness program, the administration approved about $4.5 million in additional student loan relief for more than 60,000 borrowers, bringing the total relief through that program to $74 million for more than 1 million people.

That brings the total amount of student debt relief under the administration to $175 billion for more than 4.8 million borrowers over the nearly four years President Joe Biden has been in office, the department said.
