How often sexual harassment training is required depends entirely on where your employees work. There is no federal schedule for private employers, but roughly a dozen states and several major cities set their own cycles, ranging from once a year to once every ten years. Annual and biennial are the two most common intervals.
Federal Law Sets No Schedule
Federal law does not require private employers to train employees on any particular timeline. The Equal Employment Opportunity Commission recommends periodic training, especially for supervisors and managers, but does not prescribe a frequency.1U.S. Equal Employment Opportunity Commission. Model EEO Programs Must Have an Effective Anti-Harassment Program
The practical pressure to train regularly comes from the Faragher-Ellerth affirmative defense. When a supervisor harasses an employee but does not fire, demote, or take similar action against them, an employer can avoid liability by showing it took reasonable care to prevent and correct harassment and that the employee unreasonably failed to use the available complaint process. A written policy, a clear reporting channel, and a regular training program are the core evidence courts look at.2U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Vicarious Liability for Unlawful Harassment by Supervisors An employer that has not trained anyone in years will have a hard time meeting that standard.
States That Require Annual Training
New York State and New York City
Every employer in New York State, of any size, must train all employees once a year.3The State of New York. Sexual Harassment Prevention Model Policy and Training New York City adds its own annual requirement for employers with 15 or more employees, or at least one domestic worker, along with additional city-specific standards. Skipping the annual training violates the New York City Human Rights Law, and employees can file complaints with the city’s Commission on Human Rights.4NYC Commission on Human Rights.

Illinois and Chicago
Illinois requires annual training for every employer with employees working in the state. The statute doesn’t set a minimum number of hours, but content has to meet the Illinois Department of Human Rights standards.5Illinois Department of Human Rights. Minimum Sexual Harassment Prevention Training Standards for All Employers
Chicago stacks additional requirements on top. All employees need at least one hour of harassment prevention training each year, supervisors and managers need two hours, and every employee, including supervisors, needs one further hour of bystander intervention training annually.6City of Chicago. Sexual Harassment The state’s model training covers the one-hour employee requirement; the extra supervisor hour and the bystander hour are separate.
States That Require Training Every Two Years
California
California requires employers with five or more employees to run training every two years. Non-supervisory employees need at least one hour, and supervisors need at least two. New hires must be trained within six months of their start date, and the next statewide compliance deadline is January 1, 2027.7California Civil Rights Department. Sexual Harassment Prevention Training – Information for Employers
One wrinkle catches employers off guard. Independent contractors, volunteers, and unpaid interns count toward the five-employee threshold even though the employer doesn’t have to train them. Two paid employees plus six unpaid interns is enough to trigger the biennial training obligation for the two employees.7California Civil Rights Department.

Delaware
Delaware requires training at employers with 50 or more employees in the state. New employees must be trained within one year of their start date, and everyone repeats the training every two years after that. Supervisors follow the same cadence but receive additional training on handling complaints and taking corrective action.8Delaware General Assembly. Chapter 399
Other Training Schedules
Connecticut: Every Ten Years After Onboarding
Connecticut requires employers with three or more employees to give every new hire two hours of training within six months of their start date. After that, supplemental training is required at least every ten years.9Commission on Human Rights and Opportunities. Sexual Harassment Prevention Resources That is the longest interval any state has adopted, and most compliance professionals treat it as a floor rather than a target.
Maine: Once, Within a Year of Hire
Maine requires employers with 15 or more employees to train new employees within one year of hire. Supervisory and managerial employees receive additional training on their specific responsibilities for addressing complaints and ensuring corrective action.10Maine State Legislature. Maine Revised Statutes Title 26 Section 807 – Requirements The statute does not require periodic refresher training, though repeating it annually is widely considered a best practice.
Vermont: Recommended, Not Required
Vermont recommends training for every new employee within their first year and annual refresher training for all staff, but these are recommendations rather than enforceable mandates. State guidance also calls for additional training for new supervisors within their first year, covering their legal responsibilities.
Remote and Multistate Employees
Training frequency follows the employee’s work location, not the employer’s headquarters. A Texas-based company with remote workers in California has to train those California workers on California’s schedule, even without an office in the state. California’s Civil Rights Department has said so explicitly: an employer with five or more employees anywhere must train its California-based employees, and employees located outside California are not subject to the state’s training rules.11California Civil Rights Department. Sexual Harassment Prevention Training for Employees FAQ
For workforces spread across several states, tracking each state’s schedule quickly gets complicated. A common approach is to adopt one training program that meets the strictest state’s standards and run it for everyone on an annual cycle. You over-train employees in lenient states, but you don’t miss a deadline in a strict one.
What Skipping Training Costs
The consequences fall into two categories. First, direct enforcement: state and local agencies can investigate complaints and impose penalties on employers who miss their training mandates. In New York City, missing the annual training violates the Human Rights Law, and employees can file complaints with the Commission on Human Rights.4NYC Commission on Human Rights. Stop Sexual Harassment Act
Second, and often more expensive, is indirect legal exposure. When an employee sues, the employer’s training history becomes central evidence. Consistent, documented training supports the Faragher-Ellerth affirmative defense. Gaps in the training record, or no record at all, make it much harder to argue the employer took reasonable care to prevent harassment.2U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Vicarious Liability for Unlawful Harassment by Supervisors That distinction can decide whether a case is dismissed early or ends in a settlement check.
