Who is an Internal Auditor?

An internal auditor is qualified accounting professional. The Board of Directors of the company appoints an internal auditor to perform auditing within a company. An auditor is a person or a corporation that a company hires to carry out an audit. A person must be qualified by the organization that oversees accounting and auditing, as well as meet other requirements, to operate as an auditor. Generally speaking, a person needs a certificate of practice from the regulatory body to serve as the company’s external auditor. An internal auditor is often a company employee, though some businesses choose to retain an outside professional instead. Internal auditing is a free-standing, impartial assurance and consultation process intended to enhance an organization’s performance. Bringing a methodical, disciplined approach to assessing and enhancing the efficacy of risk management, control, and governance procedures may help a company achieve its goals. Internal auditing may be able to accomplish this by offering knowledge and suggestions based on analyses and evaluations of data and business procedures. As an impartial source of independent counsel, internal auditing benefits governing bodies and top management by being committed to integrity and responsibility.

Organizations use experts known as internal auditors to carry out the internal auditing activity. The scope of internal auditing within an organization can be very broad and may cover subjects like governance, risk management, and management controls over: efficiency/effectiveness of operations (including asset protection), the accuracy of financial and management reporting, and compliance with laws and regulations. In addition to participating in fraud investigations under the supervision of fraud investigation specialists, conducting proactive fraud audits to spot potentially fraudulent acts, post-investigation fraud audits to spot control failures, and conducting post-investigation fraud audits to establish financial loss are all examples of internal auditing activities. An internal auditor’s (IA) primary responsibility is to spot issues and address them before they are found during an external audit by a company from outside or by regulatory bodies like the Securities and Exchange Commission (SEC). To ensure that investors have access to all relevant information before investing, one of the SEC’s responsibilities is to supervise how corporations disclose their financial statements.

Although the management of the firm or a corporate employee may designate an internal auditor, independence is the primary requirement for the performance of an internal audit. The independence of an internal audit may be compromised, which could affect its objectivity. Internal auditors guide management and the board of directors (or other similar oversight bodies) on how to better carry out their duties. They are not in charge of carrying out business activities. Internal auditors may come from a range of higher educational and professional backgrounds due to their wide range of participation. The Certified Internal Auditor title is given internationally by the Institute of Internal Auditors (IIA), which is a recognized international standard-setting authority for the internal audit profession. There are more classifications available in some nations. An internal auditor delivers a report to the Board and is administratively and functionally accountable to the Board to the management of the organization. Internal auditors need to be analytical thinkers who are passionate about enhancing the internal control framework of an organization if they are to be successful. The best candidates will have outstanding report-writing and presentation skills as well as outstanding business knowledge.

How to Become an Internal Auditor

Step 1: Earn a Bachelor’s Degree

An appropriate educational background is needed to be an internal auditor. A bachelor’s degree is typically required by organizations searching for knowledgeable internal auditors, particularly one with a financial, accounting, or similar field of study emphasis. It’s also possible to succeed by earning a bachelor’s degree with a concentration in math, auditing, or accounting. Joining groups that support your efforts to create a strong resume might be something you want to think about. A master’s degree in finance or another similar discipline, such as taxation, financial accounting, auditing, business law, or business communication, is preferred by some employers. Another option to take into consideration is educational institutions that provide graduate or undergraduate degree programs with an internal auditing concentration. Although a master’s degree is not necessary for internal auditors, several states need professionals to complete further college coursework after receiving a bachelor’s degree to qualify for the Certified Public Accountant (CPA) designation. Internal auditors are better positioned to compete for senior roles and career advancements by earning a graduate degree in a related discipline.

Step 2: Complete Training Programs

Newly recruited internal auditors must complete a training phase, per employer requirements. The employer assigns a skilled and experienced worker to supervise and mentor the new hire during this time. Depending on the position and the firm, the training time may run anywhere from a few months to more than a year. Following the completion of their bachelor’s or master’s degrees, internships may also offer internal auditing training programs. Through an internship, students can get real-world, hands-on experience in the sector of their choice. Students might finish several internships while in college. Internships are occasionally needed for post-graduate programs to meet graduation requirements.

Step 3: Acquire Certified Internal Auditor Exam Work Experience

The CIA exam’s job experience criterion must be met to become an internal auditor. Some employers impose a work experience requirement before the CIA exam for prospective internal auditors. The amount of work experience necessary is based on the highest educational level. In addition to internal audit experience, practical expertise in a particular audit or assessment discipline, such as internal control, quality assurance, compliance, or external auditing, may be accepted in place of this experience requirement. For verification of work experience, it is advisable to get in touch with the Institute of Internal Auditors (IIA). You can make sure that your work experience fits into the IIA’s recognized categories in this way.


Step 4: Pass the CPA Exam

A certified public accountant (CPA) is a type of financial counsellor who helps companies, people, and other organizations plan for and meet their financial objectives. The CPA Exam evaluates the abilities and expertise of beginning CPAs. Some employers demand that prospective internal auditors finish and hold a CPA. It’s a good idea to sign up for a test date and get started preparing for the CPA examination right away if you’re interested in a position that calls for this certification. Employ the appropriate study methods to pass the CPA exam. The AICPA provides free access to the fundamental study materials for the CPA Exam. Additionally, they offer free CPA Exam practice exams as well as a video that demonstrates how to use the CPA Exam platform. Instead of cramming all of your studying into one long period, it is best to prepare for difficult examinations like the CPA in small bursts with intervals in between. There is no benefit to sitting down and studying all at once. There is a limit to how much information our brains can store at once before we start to become distracted. An excellent place to start is with 10 weeks of 10 hours per week of study. Online review courses can be of great assistance, but we advise using them judiciously. Practice CPA tests are available in the top online review programs. As you study, this makes a more accurate simulation of the CPA exam testing atmosphere. Additionally, it’s crucial to treat practice questions seriously as you progress through the review course. Even though it is only a practice exam, it is best to approach it seriously.

Step 5: Acquire Additional Certifications

You should consider obtaining extra qualifications if you want to specialize in a particular area of internal auditing. Candidates for employment will benefit from this in the labour market. Obtaining certificates demonstrates to potential employers that you are focused and determined. Depending on the precise type of internal auditing you’re interested in, there are a variety of different certifications available. These certifications include:

  • Certified Internal Auditor (CIA) certification is offered by the Institute of Internal Auditors (IIA).
  • Certified Public Accountant (CPA) certification is offered by the American Institute of Certified Public Accountants (AICPA).
  • Certified Government Auditing Professional (CGAP) certification is offered by the Internal Audit Association (IAA).
