The automatic enrolment of children for free school meals should become a standard practice, a councillor has said following a successful trial.
The scheme, run by Fix Our Food research programme and councils, identified previously unregistered, eligible children and signed them up automatically.
As a result, 2,500 more children across County Durham have started receiving a free school meal since the pilot began in September.
Head teachers said the scheme was "the way forward" as it helped pupils and their families.
