Last updated: November 2026
This guide is about working for California state government, the departments in Sacramento and around the state, not for a city, a county or a US Senate office. There's no single State of California internship. Most paid student work runs through a civil-service job class called Student Assistant, which any department can post on CalCareers at any time of year. On November 12, 2026, seven student-class postings were open, at the Department of Finance, the State Treasurer's Office, the Department of State Hospitals, the Department of Rehabilitation, the Business and Consumer Services Agency and a behavioral health oversight commission. The posted Student Assistant range is $3,167 to $4,268 a month (Department of Finance posting), and filing windows we measured ran 10 to 30 days. In plain words: you can apply to a Student Assistant posting whenever one is open, and for Cal OES's unpaid summer program you apply from January 15 to February 12, 2027 and intern in summer 2027.
Quick Facts
| Fact | Detail |
|---|---|
| Where to apply | CalCareers student employment page: make a CalCareers account and search by the classification "Student Assistant", not the word "internship". Save the search to see new postings. Cal OES's summer program applies through its internship page |
| Application window (2027–28) | Student Assistant: year-round, one posting at a time; open now, with filing dates of November 19 (Finance, Behavioral Health Services Oversight and Accountability Commission), December 3, 2026 (Business and Consumer Services Agency) and "Until Filled" (four others). Cal OES for summer 2027: January 15 to February 12, 2027. Capital Fellows (graduates) 2027–28: closed November 10, 2026; the 2028–29 round is expected to open around September 2027 |
| Rolling? | Partly. Departments post Student Assistant jobs all year, but each posting has a short filing window (10 to 30 days on the dated postings we measured) unless it says "Until Filled". Cal OES has one fixed window |
| Eligibility | Student Assistant: proof of application for, or enrollment in, a college program related to the department's work; non-testing class. Hires must live in California once hired. Some postings require US work authorization or rule out visa sponsorship. No GPA floor on the class spec or postings we read |
| Duration | Student Assistant: part-time or temporary, scheduled around classes, up to 1,500 hours in 12 months; employment depends on staying enrolled. Graduate Student Assistant: about 20 to 30 hours a week (Rehabilitation). Cal OES: 10 weeks, June to August |
| Compensation | Student Assistant: $3,167 to $4,268 a month posted range, new hires at the minimum; Patton State Hospital posts it as $18.27 to $24.62 an hour. Engineering and Architectural Sciences: $3,167 to $4,881 a month. Graduate Student Assistant: $3,724 to $5,810 a month. Ranges don't reflect a 3% pay reduction under the 2025 leave program. Cal OES summer: unpaid |
| Return offers | Not published. The Student Assistant class allows no full-time permanent appointments, so a permanent job means applying to a regular state classification |
| Locations | Sacramento County for four of the seven open postings (Finance, Treasurer, the commission, the Business and Consumer Services Agency). Patton State Hospital in San Bernardino County and Rehabilitation in Visalia. Mix of hybrid and in-office. Cal OES: Sacramento County and Santa Ana |
| # Programs | No central program. Doors: Student Assistant postings (three student classes) on CalCareers, Cal OES's summer program, the Assembly Chief Clerk's internship (three campuses), Department of Justice law-student internships, and Capital Fellows for graduates |
The row that matters most: Student Assistant postings are open year-round, but each one has its own filing date, and two of the current ones close November 19, 2026.
Student Assistant postings ask for research, writing and organized office work, and a finished project helps you show it. Externships are short, remote projects you finish for a real organization, most often in 8 weeks. The Reggie Stephens Foundation AI Strategy Consulting Externship builds the research and written recommendations the Treasurer's posting asks for, and the SQL & Database Architecture Externship with Breaking Games builds the database skills behind "updating databases" and state IT work.

What Is a State of California Internship?
A State of California internship is usually a paid, part-time Student Assistant job with a state department, posted on CalCareers, the job system run by CalHR. The class, set up in 1972, gives students "on-the-job instruction" and "practical experience in work tasks related to their field of study", in the words of the CalHR class specification. Related classes are Graduate Student Assistant and Student Assistant (Engineering and Architectural Sciences). CalCareers says departments hire students in two ways: their own postings, or a partnership with a local college such as Sac State's University Enterprises (UEI), whose student jobs are part-time and non-benefited while civil-service Student Assistants "do earn some benefits". Departments that posted student roles this fall include Finance, the Treasurer, the Franchise Tax Board, Consumer Affairs, State Hospitals and Rehabilitation. Clinical and doctoral "intern" classes, such as Clinical Psychology Intern, aren't covered here.
When Do State of California Internship Applications Open for 2027–2028?
California runs on two calendars. Student Assistant jobs don't come in a yearly wave: departments post them whenever they need help, each with its own filing date. The dated postings we measured stayed open 10 to 30 days, and others run "Until Filled". On November 12, 2026, seven were open; a Franchise Tax Board IT posting had already closed on November 11 and a Consumer Affairs engineering lab posting closed November 12. The named summer programs are fixed: Cal OES takes applications for summer 2027 from January 15 to February 12, 2027, about four months before a June start. The post-graduate Capital Fellows deadline for 2027–28 passed on November 10, 2026.
Open. Seven student-class postings are live on CalCareers: Finance and the Behavioral Health Services Oversight and Accountability Commission close November 19, 2026, the Business and Consumer Services Agency closes December 3, 2026, and the State Treasurer's Office, two Patton State Hospital postings and a Rehabilitation graduate post run Until Filled. Capital Fellows 2027–28 closed on November 10, 2026.
Keep a saved CalCareers search on the Student Assistant class, since new postings appear all year. Get the state application (STD 678), proof of enrollment and your course schedule ready. Law students: Department of Justice section windows for summer 2027 start in January.
Cal OES Summer Internship Program applications for summer 2027, a dated window on Cal OES's own page. The program is unpaid and needs at least 20 hours a week.
Assembly Chief Clerk interns start in February (Sac State, UC Davis and UC Merced students only). Department of Justice sections close their summer 2027 windows, such as Correctional Law in San Francisco on February 19. Student Assistant postings keep appearing.
Cal OES interns serve 10 weeks, June to August. Student Assistants work through the summer around their schedules. For graduates, the Capital Fellows 2028–29 round is expected to open around September 2027.
How to read this page: our dates come from tracking previous recruiting cycles and daily posting data. Treat them as informed estimates based on historical patterns, not confirmed dates. The company's official careers page is always the most current source. If a role is posted there, go by that, even if this page suggests the window hasn't opened yet.
Why You Must Apply the Week Applications Open
This is a short-window system. Each Student Assistant posting sets its own final filing date, and the ones we measured gave 10 to 30 days: the commission's HR post opened November 9 and closes November 19, and Finance's opened November 4 and closes November 19. A posting found late in its window may have only days left, so save a search and check it weekly. "Until Filled" postings can close whenever the department hires; the Treasurer's has a cutoff for review on the 1st of each month. Cal OES is a hard window: applications for summer 2027 run January 15 to February 12, 2027 only.
Which State of California Internship Programs Should You Target?
These are the main doors, with details from each department's own CalCareers posting or program page, read in November 2026.
| Program | Focus | Duration | Key details |
|---|---|---|---|
| Student Assistant (CalCareers) | Administrative, analytical, IT or technical support in a department, tied to your field of study | Part-time or temporary, year-round; up to 1,500 hours in 12 months | $3,167 to $4,268 a month posted range; any college program related to the work; non-testing class |
| Graduate Student Assistant | Entry-level professional work for students in advanced-degree programs | About 20 to 30 hours a week (Rehabilitation, Visalia) | $3,724 to $5,810 a month; graduate students only |
| Student Assistant, Engineering and Architectural Sciences | Lab and field work, such as equipment testing and certification at Consumer Affairs | Part-time, year-round | $3,167 to $4,881 a month; engineering and related students |
| Cal OES Summer Internship Program | Recovery, hazard mitigation, disaster logistics, homeland security, government affairs and more | 10 weeks, June to August 2027 | Unpaid; 18 or older; at least 20 hours a week; apply January 15 to February 12, 2027 |
| Assembly Chief Clerk Internship | Legislative procedure work in the Assembly Chief Clerk's office | February to September, full-time | Paid (amount not published on its page); four interns from Sac State, UC Davis and UC Merced |
| Capital Fellows Programs | Assembly, Senate, Executive and Judicial fellowships | 10 to 11 months, full-time | Graduates only; 2027–28 closed November 10, 2026; next round expected around September 2027 |
The Department of Justice runs section internships that are mostly for law students. We found no current internship page for the Governor's office (checked November 2026).
What Are the Eligibility Requirements?
Rules come from the CalHR class specification and the postings themselves, read in November 2026. Each posting can add its own.
• Enrollment: "Proof of application for, or enrollment as a student in, an appropriate college or university program", and the job lasts only while you stay enrolled. Your field should relate to the department's work.
• No exam: Student Assistant is a non-testing classification, so anyone who meets the minimum qualifications may apply.
• Graduate Student Assistant: restricted to students in a curriculum "leading to an advanced degree in a professional area".
• Residency: some postings let out-of-state candidates interview, but they must live in California once hired.
• Work authorization: Finance requires legal authorization to work in the US, and some postings say they won't sponsor a visa. The Treasurer's office requires a cleared background investigation before hire.
• Cal OES summer: at least 18 years old and able to work at least 20 hours a week. Capital Fellows: bachelor's degree by September 1 of the fellowship year, GPA 2.5 or higher, age 20 or older, and not available on F-1 or J-1 visas.
Is There a GPA Cutoff?
Not for Student Assistant jobs. Neither the class specification nor the postings we read set a GPA floor. What screens people out is the paperwork and the fit: postings ask for the STD 678 state application, a cover letter naming your major and availability, your course schedule and proof of enrollment, and they rank candidates against the posting's Desirable Qualifications. The 2.5 GPA rule belongs to Capital Fellows, a graduate fellowship.
What Skills Does the State of California Look For, and How Do You Build Them?
We read eight of the open student-class postings in full (Finance, the Treasurer, the commission's HR post, the Business and Consumer Services Agency, Consumer Affairs' engineering lab, two Patton State Hospital postings and Rehabilitation). Attention to detail appears in all eight. The Treasurer wants someone who can "work and communicate effectively, in writing and orally" and has "critical thinking and excellent research skills". The commission's HR post asks for "Proficiency with Microsoft Office applications, including Word, Excel, Outlook, Teams, and SharePoint". Analysis shows up at the Business and Consumer Services Agency, whose student provides "analytical and administrative support for operational processes, documentation, tracking, reporting, and workflow improvement".

Build These Skills Before You Apply
Each skill below comes from an open state posting and maps to a remote Externship you can work on while you apply.
| Skill (from real JDs) | JD evidence | Externship that builds it |
|---|---|---|
| Research and written analysis | State Treasurer's Office: "Critical thinking and excellent research skills" | Reggie Stephens Foundation AI Strategy Consulting |
| Databases | State Treasurer's Office: "compiling and organizing information, and updating databases" | SQL & Database Architecture Externship with Breaking Games |
| Excel and data work | Behavioral Health Services Oversight and Accountability Commission: "Proficiency with Microsoft Office applications, including Word, Excel, Outlook, Teams, and SharePoint" | Health Research & Data Analytics with ARCeH |
| Process and workflow improvement | Business and Consumer Services Agency: "tracking, reporting, and workflow improvement" | Institute of Mental Health Healthcare Operations & Consulting |
No open Externship teaches engineering lab work. For the Consumer Affairs lab track, a data project still shows the careful record-keeping its posting asks for.
What Is the State of California Application and Interview Process Like?
Each department runs its own hiring on CalCareers. The steps below come from the open postings.
1. Make a CalCareers account. One account works for every department, but you apply to each posting separately.
2. Search by classification. Use "Student Assistant" (or the keyword "student"). A keyword search for "intern" returned only three jobs in November 2026, two of them doctoral clinical roles.
3. Send the posting's checklist. Usually the STD 678 state application, a cover letter with your major and availability, your course schedule and proof of enrollment, sometimes a statement of qualifications. Submit before the final filing date.
4. Assessment. The Business and Consumer Services Agency says the assessment "can take many forms, including an interview or exam". Some interviews are in person.
5. Clearance and start. Some offices, such as the Treasurer's, require a background investigation before hire. Schedules then flex around your classes.
No department publishes an acceptance rate. Sac State's University Enterprises runs a separate student job board for state and local clients, but those hires are UEI employees, not state employees.
What State Workers on Reddit Say
On r/CAStateWorkers, current and former Student Assistants describe the job and how hard it is to land.
The job depends heavily on the unit. Commenters described anything from filing and opening mail to configuring production network equipment. One former Student Assistant came back later as an analyst at the Department of Public Health and now automates the work they once did by hand.
Commenters called UEI through Sac State the easier way in, with more openings, though years worked for UEI don't count toward state service. CalCareers has fewer student jobs and a more thorough process.
One student said they'd applied to more than 170 jobs before getting a Student Assistant interview. Commenters expected about five standard questions in roughly 30 minutes, including Microsoft Office and how you'd handle confidential information.
How Do You Stand Out for a State of California Internship?
First, search the way the state hires. The job is called Student Assistant, so a saved search on that class finds postings that a search for "internship" misses. Second, answer the posting's Desirable Qualifications in the posting's own words: the state says those factors are the basis for comparing candidates. Third, send every item on the checklist before the final filing date, since a missing proof of enrollment or course schedule can stop an application. No department publishes an applicant count or a conversion rate. The class itself allows no permanent appointment, so moving to a full-time job means applying to a regular classification; Reddit commenters say some departments like hiring their former students.

FAQ
Can I still apply for a summer 2026 State of California internship?
No, summer 2026 programs are over, but you don't need to wait for summer. Student Assistant jobs are posted year-round on CalCareers, and seven were open on November 12, 2026. For a structured summer program, Cal OES takes applications for summer 2027 from January 15 to February 12, 2027.
Does the State of California have one internship program?
No. Each department hires its own students, mostly into the Student Assistant class on CalCareers. Separate programs include Cal OES's unpaid summer internship, the Assembly Chief Clerk's internship for three campuses, Department of Justice law-student internships and the Capital Fellows Programs for graduates. You apply to each posting or program separately.
How much do State of California Student Assistants make?
The posted Student Assistant range is $3,167 to $4,268 a month, and new hires start at the minimum. Patton State Hospital posts the same job as $18.27 to $24.62 an hour. Graduate Student Assistants are posted at $3,724 to $5,810 a month. Posted ranges don't reflect the state's 3% leave-program pay reduction.
Do I need a minimum GPA?
No GPA floor appears in the Student Assistant class specification or the postings we read. You need proof of enrollment in a college program related to the department's work, and the class is non-testing. The 2.5 GPA rule you may see belongs to Capital Fellows, a fellowship for graduates.
Do I have to live in California?
You do once you're hired. Several postings say out-of-state candidates may interview but must reside in California once they're hired and start working. Some postings also require US work authorization and say they won't sponsor a visa, so read the special requirements on each posting before applying.
Is the Cal OES summer internship paid?
No. Cal OES says its internship opportunities are unpaid. The program runs 10 weeks from June to August, mostly in Sacramento County with a Santa Ana option. Applicants must be at least 18 and able to work 20 hours a week. Applications for summer 2027 run January 15 to February 12, 2027.
Is Capital Fellows still open for 2027–28?
No. The 2027–28 Capital Fellows deadline passed on November 10, 2026. It's a paid post-graduate fellowship, not a student internship, and needs a bachelor's degree by September 1 of the fellowship year. If you graduate in 2028, the next round is expected to open around September 2027.
Can a Student Assistant job lead to a permanent state job?
It can, but not automatically. The class allows no permanent appointment, so you apply to a regular classification once you qualify. The state publishes no conversion rate. On Reddit, former Student Assistants describe coming back as analysts, and commenters say some departments value students who already know the work.
Student Assistant postings open all year, so the best time to prepare is now. A remote Externship gives your cover letter a finished research or data project to point to.
