Nearly 20,000 public comments poured into the Education Department after proposed regulations would sharply limit federal Grad PLUS loans for many graduate programs. Hundreds of institutions, departments and faculty warned that restricting access to Grad PLUS will curtail enrollment in high‑need professional fields — notably nursing, public health and social work — at a moment those sectors face workforce shortages. A Chronicle analysis of submissions found urgent appeals from health‑care programs that argue Grad PLUS is a pipeline for critical workers. Commenters asked the department to refine definitions and preserve loan access for programs deemed essential to public welfare. Department officials have said they will interpret a recently passed law that ends new Grad PLUS lending but can shape its implementation through rulemaking. If the department finalizes narrow definitions of "professional" programs, colleges fear enrollment declines, program closures and weakened workforce pipelines in areas where federal borrowing has been a practical necessity for students.
