Harassment Prevention Training Requirements for Dental Offices

The training mandates covered here come from state statutes, and the six states verified for this page draw the lines at different headcounts.

Connecticut's requirement begins at employers with three or more employees.

California starts at five.

Maine's applies in workplaces with 15 or more employees, and Delaware's to employers with 50 or more employees in Delaware.

New York and Illinois sit at the other end of the scale: New York's statute reaches every employer, and Illinois requires the training by every employer with employees working in Illinois.

The training threshold is not the same thing as the liability threshold.

California's harassment provisions under FEHA apply to any employer regularly employing one or more persons — so a two-chair practice sits inside the harassment statute long before it crosses the five-employee training line.

Arizona has no training rule in this page's research, yet its civil rights law covers employers with 15 or more employees and, for sexual harassment claims, employers with one or more employees.

If your state is not in the table, treat that as a gap in this page's sources rather than a clean bill of health — this page is a snapshot of six states' statutes, not a 50-state survey, so ask your state fair-employment agency or employment counsel what applies to your practice today.

Every training mandate in the table above is state law.

Four of the six states set a deadline that starts running the day someone is hired.

California requires new nonsupervisory employees to be trained within six months of hire, and extends the same six-month window to new supervisors counting from hire or promotion; on top of that, covered employers must retrain each employee once every two years.

Connecticut requires training not later than six months after the date of hire for employees hired on or after October 1, 2019.

Delaware allows up to one year from the commencement of employment, then puts everyone on a two-year cycle.

Maine gives new employees one year from their start.

New York and Illinois work differently.

Their statutes require the training annually for all employees, and the provisions this page cites set no separate new-hire window — the annual cycle is the requirement.

Nothing stops you from training a new hire immediately, though, and in a dental office the first week is the natural slot: a new assistant should not spend months chairside before anyone has covered the subject with them.

Refreshers follow the same table.

California retrains every employee once every two years, New York runs annually, Illinois requires the training at least once a year, and Delaware repeats every two years after the first session.

Connecticut's cited provision covers the initial six-month deadline and Maine's covers the one-year window for new employees; neither sets out a refresher interval in the sources behind this page, so confirm the expectation with your state agency before you assume one exists.

Whatever your state's deadline, attach the training to your onboarding checklist so it happens the same way for every hire, and put the due date on a calendar the day the offer is accepted.

These deadlines are measured from hire — not from the employee's first slow week, and not from whenever the next group session happens to land.

Two of the six statutes cited here get specific about content, and both are detailed.

New York's model sexual harassment prevention training program must be interactive, and must include an explanation of sexual harassment, examples of unlawful conduct, the remedies available, and employees' rights of redress — and an employer may use the state model or a program that meets or exceeds it.

California requires training in a classroom or another effective interactive format, and its statute adds two further components: prevention of abusive conduct, and harassment based on gender identity, gender expression and sexual orientation.

Delaware's statute likewise requires the training to be interactive.

Connecticut pairs its training rule with a notice duty.

Employers with three or more employees must post information concerning the illegality of sexual harassment in a prominent and accessible location, and send each new employee the state's information within three months of the start date.

The posting lives with the rest of your workplace notices; the mailing is one more item for the first-month paperwork.

Beyond the statutory floor, the content is where a dental office earns its keep.

Build scenarios the team will actually recognize — a comment made at the chair while a patient is in it, jokes at the front desk, a patient who repeatedly crosses a line with one particular assistant.

The statutes tell you what subjects to include; they do not tailor the examples to a practice, so that part is yours to do.

One caution if you go looking for a national content template: the EEOC's April 2024 enforcement guidance on harassment was partly vacated, with nationwide effect, by a federal court on May 15, 2025.

Treat that guidance as a document to check in its current form, not a settled national standard, and anchor your program to your own state's statute and model materials.

Where the statutes split roles, the difference is hours and timing.

California requires at least two hours of training for all supervisory employees and at least one hour for nonsupervisory employees, and a new supervisor's six-month clock runs from hire or promotion.

Maine requires the training program for all new employees within a year and adds further training for supervisors and managers within one year as well.

New York and Illinois take the other approach: their annual requirements cover all employees, without a separate supervisory track in the provisions this page cites.

Connecticut's rule keys to the employee rather than the role — the six-month deadline applies to employees hired on or after October 1, 2019.

Delaware's statute applies to new employees generally, likewise without a supervisory split in the text quoted here.

The classification question is still yours to answer, and it is defined by each state's law.

In a dental practice the line rarely lands where job titles suggest: a lead assistant who assigns the schedule, directs the other assistants and weighs in on discipline may be a supervisory employee under your state's definition even without the title.

Read the definition in your state's statute before booking sessions — in California, putting a true supervisor in the one-hour nonsupervisory course instead of the two-hour supervisory one is a shortfall that surfaces at the worst possible time.

If you are the owner-dentist and you direct the team's work, plan on the supervisory session wherever your state requires one, and ask employment counsel if the answer is genuinely unclear.

The hour or two you sit through it is cheaper than re-running training for the whole office later because someone was booked into the wrong course.

Three of the sources behind this page carry a paperwork rule of their own.

California regulations require employers to keep documentation of the training for a minimum of two years, including the names of the employees trained and the date of training.

Maine employers must keep a record of the training, including a record of which employees received it.

And in New York City, employers must keep a record of employees' training and retain it for three years, per the NYC Commission on Human Rights — a rule a Manhattan practice needs to satisfy on top of the state's annual training requirement.

The other states' provisions quoted here set no retention period, and silence is not a reason to keep nothing.

When a harassment allegation surfaces later, the first questions are factual: who was trained, when, on what content, and by whom.

A training log is what answers them.

Keep one entry per employee: name, role, date, session length, format, provider or course name, the topics covered, and a copy of the completion certificate or signed acknowledgment.

Note who organized the session.

Add each new hire as they complete the training, and check the log against your roster whenever a two-year or annual cycle rolls around — that is how you catch the employee who joined mid-cycle and quietly missed a session, which is exactly the gap the record rules above exist to close.

Completed training certificates do not run a policy.

The policy is the short document that says what your practice forbids, how a complaint gets made, and what happens next — and in a small office it can be a single page inside your employee handbook.

What matters is that it exists in writing, that every employee has actually seen it, and that it matches what you do when someone complains.

Five elements do the work.

State the prohibited conduct in plain words — harassment of any employee, by any other employee, supervisor, owner or patient.

Give more than one way to report: the owner, plus a second named person who is not the complainant's direct supervisor, because in a five-chair office the direct supervisor may be the subject of the complaint.

Say plainly that no one will be retaliated against for reporting or cooperating.

Commit to looking into every complaint promptly and acting on what you find.

And state the consequence side: violations lead to discipline, up to termination, regardless of the offender's position.

Tie the policy and the training together and each makes the other work: the training teaches the team what the policy says and how to use it, and the policy gives the training somewhere to land.

Review both when you hire, when someone moves into a lead role, and whenever the roster or schedule changes shape — the moments when small-office dynamics actually shift.

Harassment training is one compliance thread among many that come with employing people.
