The Assurance Ladder

Each engagement buys a different level of assurance, and the report and procedures follow from it.

How the exam words it

The playbook

  1. 1Place the engagement on the ladder: audit gives reasonable assurance and an opinion, review gives limited assurance in negative form, compilation and preparation give no assurance, agreed-upon procedures give findings.
  2. 2Match the procedures to that rung: audit tests, review inquiry and analytics, compilation and preparation none.
  3. 3Match the report to that rung, and remember SSAE 19 removed the use restriction on agreed-upon procedures reports.

The trap

Saying a review gives reasonable assurance, or that agreed-upon procedures end in an opinion. A review is limited assurance in negative form, and an AUP report states findings only.
