Verify You Meet California's Prerequisites
Before starting your training, confirm you meet the prerequisites for a Dental Hygienist in California. These include being at least 18 years old, having a high school diploma or GED, and being in good health. Visit the Dental Hygiene Board of California's website to download and review the specific requirements and any necessary forms. Processing times for verifying prerequisites typically take 1-2 days.
Tip
Order your high school transcript online through Parchment.com ($15) to avoid a 2-week mail delay from your school's registrar office.
Complete Background Check and Health Screenings
All applicants must pass a background check and complete health screenings, including a TB test and proof of vaccinations. In California, this involves getting fingerprinted via LiveScan. Find a LiveScan location near you and schedule an appointment. The results typically take 2-3 weeks to process. If you have a criminal record, you may need to apply for a waiver, which can extend the timeline.
Tip
Schedule your LiveScan appointment early in the process to avoid delays in application processing.
Research and Choose an Approved Training Program
Select a state-approved training program in dental hygiene. These programs must meet specific criteria set by the Dental Hygiene Board of California, including 2150 total hours of instruction (600 classroom hours, 1550 clinical hours). Attending a non-approved program will make you ineligible for licensure. Verify program accreditation on the Board's website before enrolling.
Tip
Use the Board's online directory to filter programs by location and cost to find one that best fits your needs.
Enroll in and Complete Training
Once you've chosen a program, complete the enrollment process and begin your training. The program will consist of 2150 hours of instruction, split into 600 classroom hours and 1550 clinical hours, over approximately 18-24 months. Be proactive in managing your schedule and commitments to ensure you meet all program requirements within this timeframe.
Tip
Stay organized and keep a detailed calendar of your classroom and clinical hours to ensure you meet the program's requirements.
Prepare for the Competency Exam
Begin preparing for the National Board Dental Hygiene Examination (NBDHE) administered by the Joint Commission on National Dental Examinations. The exam consists of a written test with 350 questions covering various aspects of dental hygiene. You have a 4-hour time limit. Study materials and practice exams are available online. Failing the exam allows for rescheduling, but additional fees apply.
Tip
Regularly take practice exams available on the JCNDE website to familiarize yourself with the exam format and question types.
Register for and Schedule the Exam
After preparing for the NBDHE, register and schedule your exam. This can be done through the JCNDE website. Choose a testing center and a date that gives you sufficient time to prepare. Be aware that testing slots can fill up quickly, especially during peak testing periods, so schedule as early as possible to secure your preferred date.
Tip
Check the testing center locations and availability frequently if your preferred date is not initially available.
Take and Pass the Exam
On the day of the exam, arrive at the testing center early with two forms of ID and all required materials. The NBDHE consists of 350 questions and lasts 4 hours. Results are typically available within 3-4 weeks. If you fail, you can reschedule, but you must pay the exam fee again. Passing the exam is crucial for proceeding with licensure.
Tip
Ensure you have all necessary materials and arrive early to avoid any last-minute issues that could affect your performance.
Apply for State Certification/Registry
After passing the NBDHE, apply for your Dental Hygienist license through the Dental Hygiene Board of California. Complete the application form, attach all required documents including your exam results, and pay the application fee. Processing typically takes 4-6 weeks. Once approved, your license will be issued and your name will be added to the state registry.
Tip
Double-check your application for any errors or missing information to avoid delays in processing.
Receive Your Certification and Verify on State Registry
Once your application is processed and approved, you will receive your Dental Hygienist license by mail. Verify your name and license details on the Dental Hygiene Board of California's online registry. This confirmation is essential for legally practicing in California and must be maintained with regular renewals as specified by the Board.
