Assurance, attestation, and auditing services share some commonalities; attestation services fall under the big umbrella of assurance services and auditing services are a part of the broader circle of attestation services. Demonstrate the differences between auditing, assurance, and attestation services provided by CPAs. Make sure that you describe the scope of services that are different between the three types of services. Provide examples of each type of service. Discuss the standards that apply to each type of service auditing, attestation, and assurance and explain the similarities and differences between these standards; include the standard setting bodies in your explanation.
