The Walton Family Foundation is reportedly donating $50 million over a three-year period to Teach For America.

According to the Associated Press, the grant will go towards the recruitment, training and development of 4,000 new teachers. Teach for America, which will soon celebrate it's 25th anniversary, is a nonprofit organization that recruits college graduates to teach for a minimum of two years in low-income areas throughout the U.S.

The members will be placed in cities such as Atlanta, Memphis, New Orleans, San Antonio, Houston, Los Angeles and the San Francisco Bay Area. The also grant includes communities in Arkansas, Colorado, Massachusetts, New Jersey and Washington, D.C.

The Mississippi River Delta region in particular will receive $4,757,500 towards 800 new teachers, Arkansas Online reports.

The Mississippi Delta is one of the country's most impoverished areas. According to Arkansas Education Commissioner Johnny Key, the pool of potential teachers in the area is rapidly dwindling. Enrollment of candidates in education training programs dropped from 8,255 in 2010 to 5,258 in 2015.

"Nontraditional teacher preparation programs like Teach For America have been important partners in meeting the demand for teachers in many of our school districts in Arkansas," Key said. "This support from the Walton Family Foundation will strengthen the capacity of Teach For America to develop educators who can provide student-focused learning opportunities."

The Waltons, heirs of Bud and Sam Walton who founded Walmart and Sam's Club, are among the richest families in the world. Their foundation has been supporting Teach For America since 1993, shortly after its inception.

Jared Henderson, executive director of Teach For America in Arkansas, thanked the Walton Foundation for its continued support.

"We couldn't be more grateful for their continued investment in the training and support of our teachers, who are working side by side with fellow local educators to give their students growing up in rural communities the great education they deserve," said Henderson.
