What is the term for a certificate, license, permit, or registration that grants permission to practice?

The term that best describes a certificate, license, permit, or registration that grants permission to practice is "authorization." This term encompasses the concept of officially granting permission to individuals or entities to undertake certain activities or professions, ensuring that they meet required standards and qualifications.

Authorization typically implies that a governing body or regulatory authority has assessed the qualifications and compliance of an individual or organization with specific regulations or standards before permission is granted to operate legally. This is essential in various fields, especially those related to safety and sanitation, where the adherence to industry standards is crucial for public health and safety.

While the other terms—certification, registration, and accreditation—are related, they have more specific meanings. Certification refers to the process by which individuals verify their skills or knowledge against a standard, typically issued by a professional organization. Registration often refers to the official recording of a person or organization to validate their identity and eligibility. Accreditation involves an evaluation process to ensure that institutions or programs meet established standards, often by an accrediting body. Hence, while these terms are included in the broader scope of regulatory compliance, "authorization" specifically captures the concept of granting permission to engage in a practice or profession.
