A task force that examined the functions and structure of the University of Maine System has come out with a draft report that calls for major changes in the way the system operates. The panel said the seven campuses must act as a union and can no longer afford to pursue their own dreams and engage in expensivecompetition with each other. Specific recommendations include clearly differentiating campus missions, transforming distance education and easing credit transfers. The task force says the system faces a potential shortfall of $50 million in the next four years at a time when the state mustgraduate a third more people per year to keep pace with competitors. The report says the system can meet those demands, butmust change the way it does business.
