Since 1989, API’s Individual Certification Programs (ICP) have provided the petroleum and petrochemical industries with an independent and unbiased way to evaluate the knowledge and experience of technical and inspection personnel. These certification programs are based on the industry-developed standards that are recognized and used with confidence worldwide.

ICP testing, developed in partnership with industry leaders, confirms that certified inspectors and personnel will demonstrate competence in content areas that are relevant to their practices.

API’s certifications have come to be regarded as the most demanded and desired credentials in the industry. They provide applicants with means to improve their skills through learning and strengthening their overall job performance. API certified inspectors and personnel are recognized worldwide as professionals who are fully knowledgeable of the relevant industry inspection codes and standards, and who are capable of performing their jobs in accordance with the latest and most acceptable industry inspection practices.

API certification allows qualified personnel to establish a career path and make valuable contributions to the safety and quality of industry operations.

API's individual certification programs benefit the industry by:

  • Providing knowledgeable specialized inspectors
  • Establishing a minimum standard of knowledge and skill for the personnel
  • Providing higher management control of inspection practices
  • Increasing employer’s confidence and peace-of-mind
  • Helping maintain safety and high level of performance
  • Reducing potential for downtime because of equipment failure

API Introduces Instant Preliminary Scoring with March 2015 Exams

Starting with the March 2015 certification exams, ICP will begin providing preliminary scores at the completion of computer-based examinations. After the March trial run, the preliminary scoring will be instituted for all other exams. As most candidates know, API does not finalize the scores until all candidate exam challenges have been reviewed by a committee of subject matter experts. This review frequently results in a change to the scoring process, and that’s why the instant scoring will only yield the preliminary results. The final results will be released 6-8 weeks after the testing window ends.

Preliminary results for the 510, 570, 653, and TES examinations will have three levels:

  • Preliminary Pass
  • Marginal (score too close to call)
  • Preliminary Fail

For all other exams either a Preliminary Pass or a Preliminary Fail result will be issued. This preliminary scoring system will help the majority of candidates determine whether they need to submit a reschedule application to take the exam again, and whether to continue their studying efforts.

I’m having trouble logging into my account. What can I do?

If you have difficulties logging into your API account, or a problem submitting an application for certification, please contact the ICP Help Desk at or call 1-877-562-5187.

Why isn’t my application accepting an email address for my employment verifier?

The ICP Portal will only allow you to add a business email address. Addresses from public domains, such as Gmail, Yahoo, etc. are not accepted.

Why was my application marked as Unqualified and what happens next?

Before submitting an application, please read the qualification requirements for your selected program. The necessary minimum experience MUST be documented on the application. Applications that do not meet the minimum requirements or do not contain all the necessary information will be marked as unqualified and API will issue a refund of the application fee minus a $100.00 processing charge. Candidates will then need to submit a new application and pay a full application fee again.

Review the Qualification Requirements for your program.

Do I need to take a training course for the test?

No, ICP does not require candidates to take a training class to prepare for exams. It is the candidate’s decision to attend training before an ICP examination. API does not endorse test preparation classes, courses or companies. Classes on specific API standards are periodically offered through API-U Training and may be useful to the candidate. Other classes that are part of a certification requirement, such as the Auditor Certifications, are routinely offered through API-U.
Questions on ICP examinations are derived from the publications listed in each program's Publications Effectivity Sheet. Additional information and precise topics are included in the program’s Body of Knowledge. These documents, along with other pertinent reference materials, are found on the Exam Info tab for each ICP Certification.

Can I schedule my exam with Prometric if I have a deficiency on my application?

API may allow you to take an exam while waiting on employment verifications, or copies of a diploma/transcripts. In these instances, an email notification will be sent from API stating the reason(s) that your application is deficient. However, API will not complete your certification or certification renewal until all deficiencies have been cleared.

I cannot locate a Prometric testing center near me.

There are more than 500 computer testing centers worldwide from which to choose. When selecting a testing location on the Prometric website, it is always best to search by city, not by country. Prometric’s search engine defaults to a 200-mile radius. Try expanding your search as far out as 400 miles, or search using a different city name. If you still cannot locate a testing center, please contact

The Prometric website does not show any openings at my preferred testing location.

All Prometric computer testing centers operate on the first-come-first-served basis. Therefore, API cannot promise that you will be able to obtain a seat at your preferred location. Schedule your exam immediately upon receiving your Exam Authorization Notice email. If seats are not available, please try a different date, or another nearby location. If you still cannot find a seat, please contact the ICP Exam Coordinator.

How are ICP exams scored?

API 510, 570, 653, TES & 1169 Exams:  
  • The pass points for these exams will differ with each exam period.  Each examination has different questions in it, and consequently, different examinations will vary in the level and range of difficulty. API uses an industry-standard statistical process called equating to adjust the pass mark according to the relative difficulty of the exam form. Thus, the passing point used for each examination always represents the minimum knowledge required and the absolute knowledge standard is held constant. The test results of candidates only reflect whether they have this minimum amount of knowledge or not. Passing the examination is not affected by any other candidate's performance.
  • API follows the industry standard of using multiple forms (exams) during the same exam period.  This means that the person next to you may be taking a different exam with different questions and the two exams will vary in the level of difficulty and will have a different pass point. The equating process adjusts the pass mark according to the relative difficulty of the exam form.

API 571, 577, 580, 936, SIFE, SIRE, and all Auditor Exams:

  • The pass point for these exams will remain constant from exam to exam.  See each program’s Exam Info pages for details.
For the API 510, 570 and 653 exams, there are 150 questions, of which only 125 are scored. The remaining 25 are pretest questions. Learn more about pretest questions here.
Pretest Questions
ICP provides preliminary score results immediately following most computer-based examinations. Scores are not final until all candidate exam challenges have been reviewed by a committee of subject matter experts and adjustments, if any, are made. This preliminary scoring system will help the majority of candidates determine whether they need to submit a reschedule application and continue with their studying efforts.  All exams have Preliminary Pass and Preliminary Fail, with the exception of API 510, 570, 653, 1169 and TES.
  • Preliminary results for the 510, 570, 653, 1169 and TES examinations have three levels:
    • Preliminary Pass
    • Marginal (score too close to call)
    • Preliminary Fail

When will I receive my exam results?

Examination results are typically released 6-8 weeks after the final day of the testing window. Results are emailed directly from Prometric to the email address that you provided when you scheduled your exam on Prometric’s website.

When will I be certified?

The certification process typically takes 2-4 weeks after exam results are released, at which time a paper certificate and wallet card will be mailed to the “Preferred” address in your API account profile.

NOTE: If you pass the exam and your application is showing “Scheduled-Deficient,” API will not certify you until all deficiencies are cleared. Please log into your account in the ICP Portal and select the “Notifications” tab across the top of your account. Review your Deficiency Letter and submit the necessary information so that your certification can be completed.

If you have questions, please contact ICP customer service at 202-682-8064, or by email at

Where do I take my Recertification Web Quiz?

The API 510, 570 and 653 inspectors are required to take an on-line, open-book quiz every six years to renew their certification. To take your recertification quiz, or to determine if a quiz is needed for your current certification, log into your account in the ICP Portal. If a web quiz is due, there will be an Alert at the top of your certification page with a link that will take you to the quiz. NOTE: The log in credentials for the web quiz is the same as the login for the ICP Portal.
Go to Certifications for additional recertification information for your program, including the Publications Effectivity Sheets for web quizzes.

How Can I Get a Copy of My Receipt?

You can print a copy of the receipt from any of your applications by going to the Applications tab on your API account, and clicking on the ID link located on the left side of the page. On the Application Details screen, click on the ICP number located under “Invoice/Payment Details.”
