College financial aid offices are warning that major student-loan changes in the “One Big Beautiful Bill” may be implemented without finalized rules or stable operational guidance ahead of a July 1 effective date. Aid offices said vendors and institutional systems cannot fully update eligibility calculations without final regulatory clarity. The result, according to the financial aid analysis, is an expected need for manual or interim calculations during the summer operational peak—when institutions finalize aid packages and resolve eligibility issues for fall enrollment. The piece argues the compressed timeline risks undermining the systems colleges use to ensure compliance and to keep students’ enrollment pathways intact.
