Elementary and Secondary Schools
The Los Angeles Unified School District (LAUSD) is the country's second largest district, with a K–12 student enrollment of more than 746,800. Geographically, it encompasses 704 square miles, an area that includes the City of Los Angeles and all or parts of 28 other cities, as well as some unincorporated areas of Los Angeles County. Faced with unprecedented economic downswings and tremendous cuts from the State of California, LAUSD had to find ways to reduce spending in 2003 by more than 360 million dollars.
Los Angeles public schools began operating under the "90-30" system in the early 1990s. To save the costs of building new schools in a district that takes in 15,000 more students each year, students attend school for 90 days, then take 30 days off, year-round.
The following is a summary of data regarding Los Angeles public schools in Los Angeles as of the 2004–2005 school year.

Colleges and Universities
The Los Angeles area is home to three campuses of the University of California system, seven from the California State University system, and twenty private colleges and universities. The two largest are the University of California, Los Angeles (UCLA), and the University of Southern California (USC), nationally known as major research universities. Other prominent colleges and universities in the area include the California Institute of Technology (Cal Tech), Loyola Marymount University, the Claremont colleges, Pepperdine University, and Mount St. Mary's College.
Libraries and Research Centers
The Los Angeles Public Library System operates 69 branches throughout the metropolitan area with a total of more than 6 million volumes. The main branch is the third largest public library in the country. The system also maintains holdings of maps, audio tapes, films and videos, art reproductions, mobile libraries, and special services for the visually impaired. Its special collections include California history, African American fiction, genealogy, Japanese prints, rare books, and the nation's largest collection of materials on food and drink, including several thousand menus, primarily from California restaurants.
Both UCLA and USC operate major libraries whose holdings number more than 6.2 million and 2.7 million volumes respectively. The Los Angeles County Law Library consists of 9 branches with a collection totaling more than 700,000 volumes in all areas of law and legal issues. More than 150 other specialized and private libraries serve the Los Angeles area.
Some of the most advanced research in the world is conducted at Los Angeles' three major institutions of higher learning (UCLA, USC, and the California Institute of Technology). Between 1923 and 2001, twenty Nobel prize winners came from Los Angeles institutions. Research activities are conducted in such fields as archaeology, oral history, folklore and mythology, international studies, AIDS, cystic fibrosis, schizophrenia, radiology and thalmology manufacturing automation, laser studies, marine sciences, sickle cell anemia, oncology, neonatology, astronomy, seismology, hydraulics, radiation, foreign policy, armament and disarmament, desert studies, and ocean studies. Los Angeles has become a mecca for researchers searching for ways to understand the changing character of America.
