MADISON, Wis. -

The University of Wisconsin-Madison is no longer ranked in the top five when it comes to research.

The latest rankings put the UW in sixth place, which is down two spots from the last rankings.

This is the first year since 1972 that UW-Madison has not ranked in the top five for research expenditures.

University officials said it has been a challenging year, and disinvestment from the state is hurting its ranking.

"This is a highly competitive environment," UW-Madison Vice Chancellor for Research and Graduate Education Marsha Mailick, the university's top research officer, said in the release. "The numbers show that our faculty and staff are highly successful, although continued disinvestment by the state is having an impact on our ability to compete."
