Course: auditing $-$ Book: Principles in Auditing & other assurance services $-$ Ch$\mathrm{.}20$ Attestation and Assurance Services While studying for the final exam of your Auditing class, one of your classmates asks if you understand the difference between attestation services and assurance services.
