The title of "consultant" can be misleading, but it generally indicates the person being consulted is an expert or professional in a particular field who offers advice. Consultants may act in the interest of private business, state business, or advise consumers in the private sector. Consultants may or may not be licensed; however, licensure will be required if there is agency jurisdiction. The determining factor is the extent of their advice and the consultant's area of expertise.
It is the consumer's responsibility to verify the credentials (education, technical training, or expertise) of a consultant before accepting such advice.
Consultants in the following categories may or may not be licensed and may or may not charge a fee. Again, the consumer must evaluate the extent of advice because the need for a license may exist (based on some agency requirement) or it may not.
