Stanford University has further expanded its financial aid program to cover more prospective students, helping them be able to attend the prestigious university.

The university has made a change to its program, which already generously helped middle-class students.

Stanford announced last week it will expand its financial aid program for the incoming Class of 2019 and all subsequent student classes, according to a press release. The new program would not charge tuition to any family with income below $125,000 a year, increasing the threshold from $100,000 a year previously.

The reformed program will also expand the benefits on room and board, exempting families making under $65,000 a year from costs. This expands the program's earlier cap of $60,000.

"Our highest priority is that Stanford remain affordable and accessible to the most talented students, regardless of their financial circumstances," said Provost John Etchemendy, according to the release.

"Our generous financial aid program accomplishes that, and these enhancements will help even more families, including those in the middle class, afford Stanford without going into debt. Over half of our undergraduates receive financial aid from Stanford, and we are pleased that this program will make it even easier for students to thrive here."

The Class of 2019 is made up of 2,144 students out of a pool of 42,487 applicants, "the largest applicant pool in Stanford's history."

The students receiving aid will be expected to contribute $5,000, but not expected to borrow for this sum. However, it does not ban parents from paying the sum.

The California university said that 77 percent of graduates leave the school without debt and added that families who make up to $225,000 annually can file for financial aid.

"This expansion of the financial aid program is a demonstration of Stanford's commitment to access for outstanding students from all backgrounds -- including not only those from the lowest socioeconomic status, but also middle- and upper-middle-class families who need our assistance as well," said Karen Cooper, associate dean and director of financial aid.

According to a Vox.com report, Stanford can afford to relieve tuition for some students as the school has an endowment of $21 billion, making it the richest in the world. The university also admits a lot of wealthy students and its median family income stands around $125,000 a year.
