For insight into a government agency's understanding of the laws it administers, one should consult:

The agency's interpretive rules.

Explanation:

An interpretive rule can be defined as a document issued by an agency so as to help expound or clarify existing administrative laws, regulations and statutes in the public domain.

Basically, an interpretive rule is not required to meet the minimum requirements or criteria specified by the Administrative Procedure Act (APA). Also, an interpretive rule is not considered as a force of law because it is not binding on the general public.

Hence, for insight into a government agency's understanding of the laws it administers, one should consult the agency's interpretive rules for an explanation on the law and regulations it promulgated,
