NASAA is the North American Securities Administrators Association, and its membership is made up of state, provincial, and territorial securities regulators (in the U.S., primarily the state securities administrators). That makes C correct. On the SIE, NASAA is tested as the umbrella organization representing state-level regulators, which are responsible for enforcing state securities laws (“blue sky” laws), registering certain securities offerings when applicable, and registering/licensing investment adviser representatives and other participants under state jurisdiction.

Choice A is incorrect because broker-dealers are regulated entities, not NASAA members. Broker-dealers register with the SEC and are members of self-regulatory organizations like FINRA, but they are not “members of NASAA.” Choice B is incorrect because stock exchanges are marketplaces and are often SROs themselves, but they are not NASAA members. Choice D is incorrect because SROs (such as FINRA or MSRB) are not NASAA members; NASAA represents state-level governmental regulators, not self-regulatory organizations.

This question reinforces an important SIE framework: U.S. securities regulation is shared among federal regulators (SEC), self-regulatory organizations (FINRA, MSRB, exchanges), and state regulators. NASAA serves as a coordinating body for state regulators, promoting uniformity through model rules, policy coordination, investor education, and cooperation among jurisdictions. Understanding NASAA’s membership helps you correctly assign regulatory roles—especially when questions involve blue sky laws, state registration requirements, and state-level enforcement.
