PhD in Criminal Justice Programs in California

Updated September 22, 2026

California has two current doctoral pathways for criminal justice study: UC Irvine’s on-campus PhD in Criminology, Law and Society, and National University’s online Doctor of Criminal Justice (DCJ). One trains researchers and faculty, while the other trains working professionals who want a terminal degree without leaving their job. Neither is required for a law enforcement career.

If you’re picturing a criminal justice doctorate as a step toward a police badge or a federal appointment, that’s not what this degree does. It’s built for people heading toward research, teaching, or senior analytical work in the justice system, the kind of career where your dissertation becomes the thing people cite, not the thing that gets you hired at an agency. Here’s what your two current California options actually look like.

What Can I Do With My PhD in Criminal Justice in California?

California’s crime rate fell for a third straight year in 2025, reaching the lowest recorded rate of Part I crime in state history, with violent crime down 10.2% and property crime down 14.3% from 2024, according to the California Department of Justice’s 2025 Crime in California report. That trend sits inside a much longer one: jurisdictions reported roughly a third as many crimes per capita in 2025 as they did in 1990. Studying why that happened, and what still isn’t working, is exactly the kind of work a criminal justice doctorate trains you to do.

Postsecondary teaching is the most measurable outcome. Criminal justice and law enforcement professors in California earn a median $139,720 a year, as of May 2025 BLS wage data. That figure covers the occupation broadly, not graduates of any specific program, and it isn’t a promise tied to either school below. California’s job growth in this field is flat for the current 2024-34 cycle, so don’t expect the field to expand, but existing positions still turn over.

Beyond teaching, UC Irvine describes its PhD as preparing graduates for research, training, and administrative work in the justice system, not just faculty roles. What you land depends on your specialization, your publication record, and the institution’s placement network, not on the degree alone.

No state or national body licenses or certifies someone specifically for holding a criminal justice PhD or DCJ. The degree itself carries no exam or credentialing requirement. If your career path runs through a regulated field, like law, psychology, or a sworn law enforcement role, that field’s own licensing rules apply separately, and a doctorate doesn’t substitute for them.

Where to Study a Criminal Justice Doctorate in California

Two current programs cover very different students.

UC Irvine’s PhD in Criminology, Law and Society is a full-time, on-campus research doctorate. Coursework covers subjects like Consequences of Imprisonment, Juvenile Delinquency, Eyewitness Testimony, Law and Morality, and Anthropology of Law, building toward a dissertation. UCI funds PhD students through up to 12 quarters of teaching assistantship support, with additional fellowships available, making this a funded research track rather than a self-pay one.

National University’s Doctor of Criminal Justice is a 100% online professional doctorate built for working practitioners, not researchers starting from a bachelor’s. Admission requires a master’s degree already in hand, and the university lists no GRE or GMAT requirement and no application fee. It’s structured for people already working in the field who want a terminal degree without relocating or leaving their job.

Confirm current admission requirements, format, and cost directly with each school before you apply. Program details shift between any given source and the day you enroll.

Frequently Asked Questions

Does California have a PhD program in criminal justice?

Yes, but there’s an important distinction. UC Irvine offers an on-campus, research-focused PhD in Criminology, Law and Society. National University offers a Doctor of Criminal Justice (DCJ), a fully online professional doctorate rather than a traditional PhD. They serve different students and different goals.

What’s the difference between a PhD and a DCJ?

A PhD, like UC Irvine’s, is a research degree built around original scholarship and a dissertation, typically aimed at academic or research careers. A DCJ, like National University’s, is a professional doctorate aimed at practitioners who already work in the field and want advanced credentials without stepping away from their careers.

Do I need a criminal justice doctorate to work in criminal justice?

No. Most criminal justice careers, including law enforcement, corrections, and probation, don’t require a doctorate. It becomes relevant specifically for postsecondary teaching positions and for research or administrative roles where a terminal degree is the employer’s stated requirement.

Is there a license or certification tied to a criminal justice PhD or DCJ?

No. Neither degree carries its own licensing exam or certification body. If you’re headed into a separately regulated profession, like law or psychology, that field’s licensing requirements apply on their own and aren’t satisfied by this degree.

How is a criminal justice doctorate funded?

It depends entirely on the program. UC Irvine funds PhD students through up to 12 quarters of teaching assistantship work plus departmental fellowships. National University’s DCJ doesn’t publish the same assistantship structure, so ask the admissions office directly about financial aid and any current tuition programs before you commit.

Key Takeaways

Two current programs – UC Irvine’s on-campus, research-focused PhD in Criminology, Law and Society, and National University’s fully online Doctor of Criminal Justice, a professional doctorate requiring a master’s for admission.
Different degree types – these serve different goals, not interchangeable versions of the same program.
$139,720 median – what criminal justice and law enforcement postsecondary teachers earn in California (May 2025 BLS), an occupation-wide figure, not a program-specific outcome.
No license required – no certification attaches to either degree itself. Regulated fields like law or psychology carry their own separate requirements.
Confirm before you apply – admission requirements, cost, and funding directly with each school, since programs change between any published source and your application date.
