U.S. News and World Report announced Wednesday that two colleges submitted inflated data that were used in the most recent rankings.

Lindenwood University in Missouri and Rollins College in Florida have recently admitted to U.S. News that they have submitted incorrect data for 2015 Best College rankings.

In the Lindenwood University case, the institution added the numeral 1 in front of the correct number of alumni donors used in the magazine's calculation of the alumni giving rate, Inside Higher Ed reported.

The university said its correct number of alumni donors in the 2012-2013 period was "2,411 versus the incorrect number of 12,411 as originally reported," U.S. News reported.

Because the misreported data resulted in Lindenwood University's higher ranking in the Regional Universities (Midwest) category, U.S. News moved the institution to its "unranked" category.

"The school's Unranked status will last until the publication of the next Best Colleges rankings and until Lindenwood confirms the accuracy of its next data submission in accordance with U.S. News' requirements," U.S. News officials said.

In the Rollins case, the misreported information did not change its rankings. The school admitted to U.S. News that its correct number of fall 2013 students admitted was 2,783 versus the 2,233 figure originally reported. This misreported information resulted in an acceptance rate of 58.8 percent, compared with the incorrect rate of 47.2 percent "that was originally reported to U.S. News, an 11.6 percentage point difference."

"The difference between Rollins' misreported data and newly reported data wasn't significant enough to affect the school's numerical rank in its ranking category. Therefore, based on our calculations, the school's published numerical rank in the 2015 Best Colleges rankings is correct and will not change," according to officials from the magazine.

U.S. News said it will continue to handle each case of data misreporting on an individual basis.
