29 CFR § 553.226 - Training time.
(b) While time spent in attending training required by an employer is normally considered compensable hours of work, following are situations where time spent by employees of State and local governments in required training is considered to be noncompensable:
(1) Attendance outside of regular working hours at specialized or follow-up training, which is required by law for certification of public and private sector employees within a particular governmental jurisdiction (e.g., certification of public and private emergency rescue workers), does not constitute compensable hours of work for public employees within that jurisdiction and subordinate jurisdictions.
(2) Attendance outside of regular working hours at specialized or follow-up training, which is required for certification of employees of a governmental jurisdiction by law of a higher level of government (e.g., where a State or county law imposes a training obligation on city employees), does not constitute compensable hours of work.
(3) Time spent in the training described in paragraphs (b) (1) or (2) of this section is not compensable, even if all or part of the costs of the training is borne by the employer.
(c) Police officers or employees in fire protection activities, who are in attendance at a police or fire academy or other training facility, are not considered to be on duty during those times when they are not in class or at a training session, if they are free to use such time for personal pursuits. Such free time is not compensable.
