Fundamentals of Internal Auditing: Two-Week Foundation for New Auditors is a 2-week course for staff in their first year of assurance work, or moving into it from finance, quality or operations. You follow one engagement from scoping to follow-up and leave with a completed First Engagement File you can reuse. Mercury Training Center delivers this fundamentals of internal auditing course.

About This Course

New auditors often join a team and are sent into fieldwork before they know how an engagement is scoped, tested, written up and closed. You should already read financial statements or business procedures at work. You practice on a guided engagement, with walkthroughs, test sheets, interviews and a draft report built step by step.

Who It Is For

  • Staff who have recently joined an assurance or inspection team and carry out fieldwork under supervision.
  • Finance, accounting and compliance staff moving into an assurance role.
  • Quality and operations staff who review procedures and want a structured engagement method.
  • Team leads who supervise new auditors and review their workpapers.
  • Board and committee secretariat staff who prepare assurance papers for directors.

This course is not for experienced auditors who already lead engagements, who are better served by an advanced practice course, or for readers seeking external financial statement audit, who need a statutory audit course.

Competencies You Will Build

  • Engagement Scoping: setting objectives, scope and criteria for a single engagement.
  • Process Walkthroughs: mapping how work flows and where key checks sit.
  • Test Design: choosing compliance, substantive or operational tests for each objective.
  • Workpaper Discipline: keeping records that let a reviewer reach your conclusion.
  • Audit Interviewing: running fact-finding meetings that stay calm under resistance.
  • Finding Writing: turning exceptions into condition, criteria, cause, effect and recommendation.

What You Will Be Able to Do

By the end of the course you will be able to:

  • Given an organization chart and prior reports, draft a one-page engagement planning memorandum.
  • From a procedure manual and a walkthrough, produce a flow diagram and a controls documentation matrix.
  • Using a population of transactions, select an attribute sample and extrapolate the results.
  • From completed test sheets, decide which exceptions are reportable and rate their significance.
  • Given a set of findings, draft the exit meeting agenda and the final report sections.
  • Using an agreed action list, set up a follow-up tracker for management responses.

Quick Answers (FAQ)

What should I know before a fundamentals of internal auditing course?

No prior auditing experience is needed. You should be comfortable reading basic financial statements or written procedures and using a spreadsheet, since sample selection and test sheets are worked in one.

How does a fundamentals of internal auditing course for new auditors differ from a shorter practitioner course?

It runs two weeks and starts from the role and governance of assurance, then walks a full engagement step by step with guided practice. A shorter practitioner course assumes you already run fieldwork and moves faster through evidence and reporting.

What does a new internal auditor do in the first engagement?

A new internal auditor usually documents the process through walkthroughs, runs the tests the senior has designed, keeps workpapers that support each conclusion and drafts findings for review. Scoping and the exit meeting are often shared with the engagement lead.

What do I take back from fundamentals of internal auditing training?

You take back a completed First Engagement File: planning memorandum, flow diagram and controls matrix, test sheets with a sample record, findings sheet, report outline and follow-up tracker, ready to reuse on your next assignment.

For Your Manager

After the course, the team member will be able to scope a single engagement, document a process, test it with a defensible sample and write findings that a reviewer can follow. They return with a completed First Engagement File, first used on their next assigned engagement and in workpaper review with their supervisor.
