Republican vice presidential candidate Sarah Palin attended five colleges in six years before graduating from the University of Idaho in 1987.

Federal privacy laws prohibit the schools from disclosing her grades, and none of the schools contacted by The Associated Press could say why she transferred. There was no indication any of them were contacted as part of the background investigation of Palin by presidential candidate John McCain's campaign.

From North Idaho College, Palin transferred 70 miles south to the University of Idaho, the state's flagship institution. She majored in journalism with an emphasis in broadcast news. She attended Idaho, whose mascot is the Vandals, from fall 1984 to spring 1985.

The McCain campaign did not have an immediate comment on Palin's higher education record.
