Which term refers to guidelines that do not mandate compliance?

The term that refers to guidelines that do not mandate compliance is "standards." Standards serve as benchmarks or criteria for performance and quality but are typically voluntary in nature. They aim to promote best practices and enhance safety, quality, and efficiency without imposing legal obligations. For example, organizations may choose to follow certain standards to improve their operations or enhance their reputation, but they cannot be legally required to do so.

On the contrary, statutes are laws enacted by legislative bodies that impose mandatory compliance on individuals or organizations. Regulations are rules created by governmental agencies, usually based on statutes, that dictate specific compliance requirements. Codes often refer to compilations of laws and regulations governing particular areas (such as building codes or fire codes) that must be followed. In summary, while all other terms refer to enforceable rules or laws, "standards" uniquely describes non-mandatory guidelines aimed at encouraging, rather than requiring, compliance.
