The specific opening date for Grad PLUS loans for the 2023-2024 academic year may vary depending on the policies of individual schools and the U.S. Department of Education. Generally, Grad PLUS loans become available for application after the Free Application for Federal Student Aid (FAFSA) opens for the upcoming academic year, which typically occurs in October of the previous year.

For example, if the FAFSA for the 2023-2024 academic year opens in October 2022, Grad PLUS loans for that academic year would likely become available around the same time.

It's essential for students to check with their respective schools' financial aid offices and the Department of Education for the most accurate and up-to-date information regarding the availability of Grad PLUS loans and other financial aid options for the upcoming academic year.
