California holds about 39.4 million people, more than any other state, and pays registered nurses an average of $150,280 a year. That is the highest figure in the country by a wide margin. Hawaii, in second place, is roughly $26,000 behind.
Licensure
The California Board of Registered Nursing licenses registered nurses. Licensed vocational nurses come under a separate board. The Board of Registered Nursing is on North Market Boulevard in Sacramento, telephone (916) 322-3350. Rules, license lookup and disciplinary records are at rn.ca.gov.
California takes no part in the Nurse Licensure Compact, and is the only state where a compact bill has never been filed. A multistate license from a compact state carries no authority here. Nurses moving to California apply to the board for a license by endorsement, which takes longer than a compact transfer and includes a fingerprint background check. See licensure by endorsement.
That combination, the highest wages in the country behind the most demanding licensing route, shapes the travel nursing market more than any other single fact about American nurse licensure.
Staffing ratios
California is the only state that writes minimum nurse to patient ratios into law for every hospital unit. Assembly Bill 394, signed in 1999, told the state to set the numbers. Regulations followed in 2003 and hospitals had to comply from January 2004.
The limits run unit by unit: one nurse to two patients in intensive care, one to four in emergency and pediatrics, one to five on medical surgical floors. They are maximums per nurse per shift rather than averages, which is the provision that gives them force, and they hold at all times including during breaks. Only licensed nurses count toward them.
Nurses arriving from other states usually find this the single biggest difference in how a shift runs. The research behind the argument, and what the three other states with mandated ratios did instead, is under nurse staffing and patient outcomes.
Nurse practitioner practice
California is classified as a restricted practice state, since nurse practitioners have long worked under standardized procedures agreed with a physician. Assembly Bill 890, signed in 2020 and phased in from 2023, opened a route out for experienced practitioners, letting those who qualify work without standardized procedures in certain settings and eventually practice on their own. The route carries requirements around supervised transition hours, so the older arrangement still governs much of the workforce. See nurse practitioner practice authority.
Nursing education
The University of California San Francisco School of Nursing is a graduate school only and one of the leading nursing research faculties in the country. UCLA, UC Irvine and UC Davis run the other university programs. The California State University campuses produce the bulk of the state's baccalaureate graduates, and the community college system produces most of the associate degree graduates, which makes the two year route a larger share of the pipeline here than in many states. See entry into practice and the BSN requirement.
Program capacity, not applicant interest, is the binding constraint. California nursing schools turn away qualified applicants every year for want of faculty and clinical placements, a problem that has more to do with what a school can pay a doctorally prepared instructor than with anything about the students. See the nurse faculty shortage.
Pay and workforce
California's registered nurse workforce is the largest of any state, spread across the Los Angeles basin, the San Francisco Bay Area, San Diego, Sacramento and the Central Valley. Kaiser Permanente, Sutter Health, Dignity Health, Providence, Cedars-Sinai and the University of California medical centers are among the largest employers.
Pay runs highest in the Bay Area and lowest in the inland and far northern counties, though even the lower California markets sit above the national range. Housing costs eat into the advantage. Because the ratio law fixes how many nurses a unit must have, hospitals cannot flex staffing down when the census dips, which holds demand steady.
California nurses are also heavily unionized, and the union that campaigned for the ratio law remains the largest in American nursing. See nurse strikes and bargaining and registered nurse pay.
Far northern California is rural and served by small hospitals and critical access hospitals a long way from a trauma center. See rural and frontier nursing.
Travel and flexible work
California is the country's largest market for travel assignments and, at the same time, an ordinary one. It accounts for more travel postings in NurseRecruiter's full archive than any other state, and once its 326,720 employed registered nurses are taken into account it ranks twenty-second of fifty-one for assignments advertised per nurse. Big is not the same as short-staffed. See where the assignments are.
Nurses want to come here anyway. California is the second most requested destination among nurses who name states they would work in, behind Florida. Every one of them needs a California licence by endorsement first, because there is no compact route in, and that queue is the main reason a Californian assignment takes longer to start than one anywhere else.
Californian nurses themselves lean towards local flexible work rather than travel: 54 percent of those with a profile on this site say they will take per diem shifts, the highest share of any state, against 36 percent for travel. In a state with this many hospitals inside commuting distance, picking up extra shifts does not require leaving home. See per diem nursing.
