NASHVILLE (AP) - An internal report on the potential outsourcing of building management at public colleges and universities warns Gov. Bill Haslam that the changes could undermine his signature "Drive to 55" effort to improve graduation rates in Tennessee.

The report titled "Strategies for Efficiency in Real Estate Management" was first obtained by WTVF-TV in Nashville. It proposes reducing office space in higher education through greater use of telecommuting and temporary offices.

But the report acknowledges that the reduced space "may be inconsistent" with Haslam's effort to boost graduation rates because data shows a correlation between student success and level of engagement with faculty and staff.

Haslam spokesman Dave Smith said questions about the report are "putting the cart way before the horse" because no decision has been made whether to pursue outsourcing.
