Vouch or Trace

Direction is the whole game: vouch back for existence, trace forward for completeness.

How the exam words it

The playbook

  1. 1Vouch from the records back to source documents to test existence and occurrence, the overstatement direction.
  2. 2Trace from source documents forward to the records to test completeness, the understatement direction.
  3. 3Start from the recorded item for existence, start from the source for completeness.

The trap

Testing the wrong direction, for example vouching to test completeness. Vouching tests existence, tracing tests completeness.
