The fall 2006 initial application filing period for California State University campuses opened on Oct. 1 and will run through Nov. 30. The CSU received 36,600 online applications during the first two weeks of the filing period. Based on last year's usage, well over 90 percent of the expected nearly 500,000 applications are anticipated to be received electronically via CSUMentor, the CSU's online resource designed to help students and their families learn about the CSU system and apply for admission.
