The recession has reached the executive suites of the nationĂ¢??s public universities and colleges, putting a stop to a string of large annual pay increases for school presidents. A survey released Monday by the Chronicle of Higher Education showed compensation packages of chief executives at public schools leveling off in 2008-2009, rising a relatively modest 2.3%. One in 10 saw their pay decline. Some who did get raises or bonuses gave the money back to their schools.
