What Is EFDA Certification in Florida?

Two different kinds of credential

A state-recognized training credential answers a legal question: may this assistant perform this task in this state? A national certification answers a professional one: has this assistant passed a standardized, third-party exam? The EFDA and the CDA sit on opposite sides of that line, and mixing them up is how assistants end up paying for the wrong thing.

A review in the Journal of Dental Education by dental educators summed up the national picture: dental assistants' scope of practice, education, and licensure options “vary by state.”^[1] That variation is the whole story here.

What EFDA means in Florida

Florida does not license dental assistants.^[2] Instead, Section 466.024, Florida Statutes, lets a dentist delegate specified remediable tasks to an assistant, and the Board's rules spell out which tasks require “formal training.”^[3][4] Under Rule 64B5-16.002, formal training means an expanded-duty course or program at a school accredited by the ADA's Commission on Dental Accreditation (CODA), or one approved by the Board for expanded-duty training.^[5]

The rule is specific about what approval requires: didactic and clinical training with stated objectives for each task, no more than ten students per instructor, an examination passed at 75 percent or higher, and a certificate that lists the sponsor, course title, date, hours, your name, an authorized signature and the tasks you completed.^[5] When Floridians say “EFDA,” this is what they mean: you completed that formal training and hold the certificate that proves it. You can read the full rule on the Florida Administrative Code site.

For the task-by-task detail, see What Can an EFDA Do in Florida? — and note that Rule 64B5-16.005, which lists tasks delegable after on-the-job training, was amended in April 2026, with further changes in rulemaking.^[6]

What the DANB CDA is

The Certified Dental Assistant (CDA) is a national certification from the Dental Assisting National Board. The CDA exam combines three component exams taken together: Radiation Health and Safety (RHS), Infection Control (ICE) and General Chairside Assisting (GC).^[7] Eligibility runs through pathways: Pathway I is graduation from a CODA-accredited dental assisting or dental hygiene program; Pathway II is a high school diploma or equivalent plus at least 3,500 hours of approved work experience; both require current hands-on CPR, BLS or ACLS.^[7] DANB certification must be renewed each year, and you must keep your CPR certificate current to renew.^[8]

The details are on DANB's CDA exam page.

Florida's position, in the Board's words

The Board's FAQ asks the question directly — “I have a certification from the Dental Assisting National Board (DANB). Is this certification valid in Florida?” — and answers it in seven words: “Florida does not recognize the DANB credential.”^[2] The FAQ also says that years of out-of-state on-the-job experience do not satisfy Florida's expanded-duty requirements: “in order to perform expanded duties you must have the training required by rule.”^[2]

So a CDA does not, by itself, authorize expanded duties in a Florida office, and passing the RHS exam is not a substitute for Florida's radiographer certification process.^[9] You can read the Board's answers yourself on its dental assistant and expanded duties FAQ.

Does an expanded-duty credential actually change your work?

It changes what a dentist can hand you — and dentists respond to clear rules. A 2026 national analysis in The Journal of the American Dental Association found that dentists were nearly 12 times more likely to delegate direct restorations in states with function-specific certificates than in states without expanded-function registration, and called these assistants “a valuable, yet underdeveloped, component of the dental workforce.”^[10] Earlier work in 154 Colorado practices found that practices using expanded-function personnel treated more patients and had higher gross billings and net incomes.^[11]

A credential is not the same as using it, though. A JADA study from the University of Minnesota School of Dentistry found that only 38 percent of practitioners certified in restorative functions actually performed them; those who did reported treating more patients.^[12] Talk with your dentist about which expanded duties the practice will delegate before you enroll — the conversation makes the training pay off.

Which should you get first?

• You work, or will work, in Florida: get Florida-recognized EFDA training first, and radiographer certification if you take X-rays. That is what changes your legal scope.
• You may move to another state: add the CDA when you can. It is the credential most likely to travel, though each state sets its own rules — check DANB's state pages before you move.
• You are starting from zero: a Board-approved entry-level program gives you the Florida credentials at graduation; you can sit for DANB exams later if you want a national credential.

FIDA's Expanded Functions (EFDA) course is approved by the Florida Board of Dentistry and built around the current DANB curriculum: 20 clock hours over five weeks, with 13 hours of online theory and 7 in-office clinical hours, covering thirteen procedures. It requires at least three months of continuous chairside training under a Florida-licensed dentist. If you have no dental experience yet, the Entry Level Dental Assisting program includes EFDA and radiographer credentials.

Five questions to ask before you pay for either

1. Is the course on the Florida Board of Dentistry's approved list, or is the program CODA-accredited? If neither, it will not qualify you for Florida expanded duties, however it is marketed.^[5][13]
2. Which tasks will be listed on my certificate? Florida's rule requires the certificate to name the tasks you completed. A vague “EFDA certificate” with no task list is a red flag.^[5]
3. Where does the clinical part happen, and who signs off? Expanded-duty training includes a clinical component. Ask whether it is in the school's lab, in your own office under your dentist, or both.
4. Does it prepare me for DANB exams too? Some Florida courses are built around DANB curriculum even though Florida does not require the CDA — FIDA's EFDA course is one. If a national credential is in your plans, that alignment can save you time later.
5. What will my dentist delegate afterward? Training only pays off if the practice uses it. Ask before you enroll, not after.^[12]

One more distinction worth knowing: the CDA is a credential you maintain — annual renewal, current CPR — while the Florida expanded-duty certificate is a record of completed training that your employer keeps on file and displays.^[8][2] If you change jobs, bring copies of every certificate with you; your new dentist will need them before delegating anything.
