An instructor who falsely claims expertise is referred to as a?

A person who falsely claims expertise is referred to as a charlatan. This term specifically describes someone who deceives others by pretending to have knowledge or skills that they do not possess. In the context of instruction, a charlatan misrepresents their qualifications and abilities, potentially leading to misinformation and harm in educational settings.

Understanding the implications of having a charlatan in a teaching position is crucial, as it undermines the integrity of education and can adversely affect students' learning experiences. This is particularly relevant in fields like emergency medical services where accurate training and knowledge are vital for effective practice and patient safety.

The other terms provided describe different facets of deception or insincerity but do not capture the specific act of exploiting false claims of expertise as accurately as "charlatan" does. A pedantic bore might indicate someone who is overly concerned with minute details but not necessarily a fraud. An imposter might suggest someone merely pretending to be someone else without the specific claim of expertise. A counterfeit instructor could suggest a fake in a broader sense but lacks the precise connotation of deceit associated with the knowledge claim.
