Iowa Admin. Code r. 761-4.8
When the department requests a person to supply information about that person, the department shall notify the person of the use that will be made of the information, which persons outside the agency might routinely be provided this information, which parts of the requested information are required and which are optional, and the consequences of a failure to provide the information requested. This notice may be given in these or other rules of the department, on the written form used to collect the information, on a separate fact sheet or letter, in brochures, in formal agreements, in contracts, in handbooks, in manuals, orally, or by other appropriate means. This rule is intended to implement Iowa Code section 22.11.
