Student Loan Eligibility Explained: Federal vs. Private

Federal Student Loan Eligibility Basics

Federal student loans are funded by the U.S. Department of Education and are generally the first option many students consider because they do not require a credit check or a cosigner for most loan types. To be eligible, you must meet basic requirements related to citizenship, enrollment, and academic standing.

The most common federal student loans include Direct Subsidized Loans, Direct Unsubsidized Loans, and Direct PLUS Loans. Each has specific eligibility rules, but they all share a core set of federal requirements. Understanding these basics can help you determine whether you are on track to qualify before you submit the Free Application for Federal Student Aid, or FAFSA.

You do not need a credit check for most federal student loans, but Direct PLUS Loans (for parents and graduate students) do require a credit check for adverse credit history.
You generally do not need a cosigner for federal loans.
You must maintain satisfactory academic progress once you are enrolled to remain eligible for future federal aid.

Who Qualifies for Student Loans? Federal vs. Private Eligibility Explained

Citizenship and Enrollment Requirements for Federal Loans

To receive federal student aid, you must be a U.S. citizen or an eligible noncitizen. You also need a valid Social Security number unless a federal exception applies. These requirements are spelled out in both official federal aid guidance and federal regulations.

You must be enrolled at least half-time in an eligible program. The U.S. Department of Education defines an eligible program as one that leads to a degree or certificate at a school that participates in federal student aid programs.

FAFSA Completion and Financial Need for Subsidized Loans

To apply for federal student loans, you must complete the Free Application for Federal Student Aid, or FAFSA. The information you provide on the FAFSA determines your eligibility for various types of aid, including need-based programs.

The type of financial need you demonstrate affects which loans you can receive. Direct Subsidized Loans are available only to undergraduate students who demonstrate financial need. Direct Unsubsidized Loans, on the other hand, are available to both undergraduate and graduate or professional students regardless of financial need.

Direct Subsidized Loans: undergraduate students only, must demonstrate financial need.
Direct Unsubsidized Loans: undergraduate and graduate/professional students, no financial need requirement.

Private Student Loan Eligibility: Credit, Income, and Cosigners

Unlike federal loans, private student loans are offered by banks, credit unions, and online lenders. Eligibility is based primarily on your creditworthiness, which lenders assess through your credit score, income, and debt-to-income ratio. A strong credit history increases your chances of approval and may help you qualify for a lower interest rate.

Many lenders look for a FICO credit score of 670 or higher, though some do not publish a minimum. If you do not have an established credit history or sufficient income, lenders often require a cosigner—a person who agrees to repay the loan if you cannot.

Eligibility for Special Borrower Groups

Several groups of borrowers have unique eligibility considerations. Parents can borrow through the Direct PLUS Loan program to help pay for a dependent undergraduate child's education. Graduate and professional students may be eligible for Direct Unsubsidized Loans and, in some cases, Direct PLUS Loans. However, note that the Graduate PLUS loan program is being phased out: as of July 1, 2026, no new borrowers are accepted, and the program will be fully phased out by July 1, 2028.

International students are generally not eligible for federal student loans, but they may qualify for private student loans if they have a U.S. citizen or permanent resident cosigner. Additionally, nontraditional students—such as those enrolled part-time or returning to school after a gap—must still meet the basic enrollment and citizenship requirements, and they may need to secure a cosigner for private loans if they lack credit history.

Do I need a credit check for federal student loans?

No, most federal student loans do not require a credit check. The exception is the Direct PLUS Loan, which checks for adverse credit history. There is no minimum credit score requirement for PLUS loans, but having adverse credit history (such as a default, bankruptcy, or foreclosure within the past five years) may require you to obtain an endorser or document extenuating circumstances.
