Accreditation	A credential used to demonstrate that an organization (e.g., a university, medical examiner’s office, forensic anthropology laboratory) meets a set of published standards [7]. Most forensic anthropology laboratories are accredited under ISO/IEC 17020 or 17025.
Best Practice	Procedures, methods, and/or techniques that have been accepted as preferable over others as they produce superior results and comply with legal and/or ethical requirements.
Beneficiaries	agents (e.g., victims, families, communities, NGOs) that can be considered interested parties (i.e., stakeholders) in the investigation, benefiting from the forensic services provided and the resolution of the investigation to varying degrees [139].
Certification	A credential provided by a professional organization demonstrating that an individual has met the knowledge and/or skills required to pass their certification process [7]. For example, the ABFA provides a certification and is accredited by the Forensic Specialties Accreditation Board.
Competency	The application of knowledge, skills, and abilities to correctly complete specific disciplinary tasks [7].
Contributory Expertise	Traditional technical expertise, where the practitioner is the contributory and interactional expert [105].
Credential	Verifiable document used to demonstrate completion of education and/or training (e.g., transcripts, licenses). Frequently used to “acknowledge, restrict, or protect the use of a title, and/or activities” [7,144] p. 220.
Education	Formal academic coursework from an accredited school, college, or university, resulting in a degree [113,145].
Expert	An individual possessing authoritative knowledge or skill in a particular area, which can be demonstrated via credentials and/or certification [7,87] pp. 29–30.
Expertise	The mastery of not only the salient, but also the tacit, areas of knowledge of a field of inquiry, which includes the ability to use the language of the field of inquiry as well as to engage fully in its practices [104].
Guideline	(i.e.: best practice documents) Published documents providing recommendations for how to perform a particular action or process. Guidelines are typically vetted and published by accredited organizations. Their content must be based on practitioner and stakeholder consensus. Guidelines are typically more detailed/descriptive than standards, but are also open to interpretation [7].
Interactional Expertise	The ability to interact with other experts using their language/jargon and understand the concepts they are discussing [102].
Qualifications	Education and training needed to demonstrate adequate knowledge to perform discipline-related tasks in an applied setting [7].
Should	Something that is not mandatory, but is professionally considered best practice.
Shall	A practice that is professionally considered mandatory.
Specialist Tacit Knowledge	Serves as the requisite knowledge base(s) to practice a discipline [100].
Standard	(i.e.: formal standards) Published documents providing mandatory rules for how to perform a particular action or process. Standards are typically vetted and published by accredited organizations. Their content must be based on practitioner and stakeholder consensus [7]. Any deviation from published standards can be considered poor practice and a breach of ethics.
Training	Formal structured process of teaching and assessment at a laboratory or other non-educational institution, often resulting in a certificate [7,113,145].
Ubiquitous Tacit Knowledge	Knowledge that is easily accessible and therefore ubiquitous [100].
