IRCA vs ITCA: Learning ISO Auditor Accreditation in 2025
Introduction
In selecting an ISO auditor course, the certifying body issuing it is more important than most realize. Two acronyms are most likely to be mentioned: IRCA and ITCA. Both provide auditor accreditation—but they are not alike in scope, acceptance, or influence.
If you’re considering becoming an ISO certified auditor by 2025, this blog will dissect all you need to know about ITCA, how it’s different from IRCA, and what recognition each offers to your career.
What is Auditor Accreditation in ISO Certification?
ISO auditor accreditation means that a person has successfully completed proper training and received a certificate to audit companies based on specific ISO standards, such as ISO 9001 for quality management or ISO 45001 for health and safety. This certification shows that the person understands how to check if a company is following the rules and processes required by the ISO standard.
But it’s not just about attending a training course. What really matters is who approved or accredited your training. Different organizations offer ISO auditor courses, but not all of them are recognized around the world. That’s why employers, government bodies, and international clients usually ask an important question:
“Is your auditor certification accepted globally?”
This is where IRCA and ITCA come in. These two organizations are responsible for accrediting ISO auditor training courses, and they each offer different levels of recognition and credibility.

Who is IRCA?
IRCA Overview
IRCA is the International Register of Certificated Auditors. It’s run by the Chartered Quality Institute (CQI) in the UK and is one of the world’s oldest and most well-known auditor certification organizations.
IRCA Course Categories
IRCA-accredited courses are:
- Lead Auditor Courses (e.g., ISO 9001 Lead Auditor)
- Internal Auditor Courses
- Transition Courses (for version changes, such as ISO 22000:2018)
Thousands of auditors around the globe are IRCA certified, and so it has become a gold standard in ISO auditing.
Key Features of IRCA Accreditation
- Accepted in more than 150 countries
- Mandated by numerous global certification bodies
- Famous for strict curriculum and trainer standards
- Encourages Continuing Professional Development (CPD)
If you want to work with multinational companies or be recognized internationally, IRCA is usually non-negotiable.
What is ITCA?
Understanding ITCA
ITCA stands for the International Training and Certification Association. While it’s newer and less globally known than IRCA, it has become more visible in certain markets, particularly in Asia and the Middle East.
Scope of Recognition
ITCA courses may be accepted by local certification bodies or government-tied organizations, depending on the country. However, its global recognition remains limited compared to IRCA.
Key Benefits and Limitations
Pros:
- Lower course fees
- Available throughout emerging markets
- Applicable for internal compliance positions
Cons:
- Poor acceptance in Europe, North America, or by top-tier certifying bodies
- Threat of having to retrain in case of applying for overseas jobs
Bottom line: ITCA is effective for localized audit professions, but it might not be acceptable in high-risk or global settings.
IRCA vs ITCA – Key Differences
Feature | IRCA | ITCA |
Global Recognition | High | Limited |
Accreditation Body | CQI (United Kingdom-based) | Independent (no common authority) |
Industry Acceptance | ISO cert bodies, multinationals | Local markets, SMEs |
Course Difficulty | Extremely High | Varies by provider |
Price | Premium | Affordable |
Renewal/CPD | Required | Depends on provider |
IRCA is often the preferred route for serious career auditors, while ITCA may be suitable for entry-level or regional compliance purposes.
Which Accreditation is Right for You?
For Career Growth
If your goal is to work with certification bodies, become a freelance ISO auditor, or consult internationally, IRCA certification will carry more weight and open more doors.
For Local/Niche Compliance
If you are conducting internal audits for a small business or simply require credentials to meet a local standard only, ITCA-accredited training may be sufficient.
Employers & Clients What They Want
- IRCA-certified auditors are usually asked for by international clients
- UK, UAE, and EU regulatory audits generally find IRCA more acceptable
- Local firms can accept ITCA if the trainer is credible and the training material is in line with ISO standards.
How to Become IRCA or ITCA Certified as an ISO Auditor
Selecting the Appropriate Trainer
Prior to registration, ensure that:
- The training institute is IRCA-approved or ITCA-accredited
- Training is for the exact ISO standard you require (i.e., ISO 14001, ISO 45001)
- Trainers possess actual audit experience
Red flag: If a course is “globally recognized” but it’s not posted on the IRCA or ITCA websites—watch out.
What it Entails For Training
- Length: Classs typically 5 days for Lead Auditor courses
- Format: Classroom, live-virtual lectures along with case studies and role-playing audit scenarios
- You have to pass an examination to achieve certification
Certification and Renewal
- IRCA: Valid for 3 years and requires CPD for renewal
- ITCA: Validity and renewal are reliant on the policy of the training body.
Common Misconceptions Regarding ITCA and IRCA Accreditation
“ITCA is bogus.”
Not false. ITCA is genuine, but it’s simply not as well recognized as IRCA. Always verify with your employer or client as to whether it’s acceptable.
“Only IRCA-certified auditors are acceptable.”
Not exactly. In local compliance situations, ITCA auditors might be completely acceptable.
“Accreditation does not count.”
It absolutely does—particularly when applying for audit contracts, foreign jobs, or serving regulated sectors such as aviation, pharmaceuticals, or government tenders.
