Which legal term is defined as "failure to conform one's conduct to a generally accepted standard or duty"?

Battery refers to intentional harmful or offensive physical contact with another person, not a failure to meet a standard of care.

Neglect is a general term often used in caregiving contexts (such as child or elder neglect) but is not the precise legal term for failing to conform to a professional standard of conduct.

Abandonment refers to the wrongful termination of a professional relationship, such as a trainer ending a session or client relationship without proper notice, not the failure to meet a conduct standard.

Negligence is specifically defined in law as the failure to conform one's conduct to the standard that a reasonably prudent person would follow under similar circumstances. This standard is central to personal trainer liability cases, where trainers are expected to meet accepted professional standards of care. When a trainer's conduct falls below this standard and causes harm, they may be found legally negligent.
