Decrease costs. Reduce Risks. Keep Your Software Out of the Headlines.®

Protect your company – and your career – by choosing testers who are ISTQB Certified by the American Software Testing Qualifications Board, the official U.S. Board for ISTQB Certification.

Logo of the Official US List of Certified TestersBefore you hire software testers or select a testing services company, make sure the testers appear on the Official U.S. List of Certified Software Testers™. When testers appear on the Official U.S. List, it proves they passed the U.S. ISTQB exams written in American English and are committed to working effectively with your U.S. software teams.

Why do you need certified testers? 88% of developers report their initial knowledge of software bugs and software errors are coming from users. Even worse: 26% said those software bugs were reported publicly via social media.[4] That’s very bad: Studies show that even one negative review can drive away 22% of your customers.[1] Certifications from ASTQB help you reduce risks, decrease costs and protect your reputation. See the 10 reasons below.

ISTQB testing certifications from ASTQB help you to:

1. Reduce software defects, coding errors, and software bugs.

Analysis shows that “a synergistic combination of defect prevention, pre-test defect removal, and formal testing by certified personnel can top 99% in defect removal efficiency while simultaneously lowering costs and shortening schedules.” That same analysis shows that “Untrained amateur personnel such as developers themselves seldom top 35% for any form of testing. Also, the ‘bad fix injection’ rate or new bugs added while fixing older bugs tops 7% for repairs by ordinary development personnel.”[2] That’s why you should pair your software developers with certified professional testers for better testing that avoids embarrassing software bugs.

2. Build cost savings and ROI.

If certification helps your tester eliminate even one extra post-production software defect (also called a software bug or programming error) sometime during their career, the return on investment for their certification would exceed 1500% based on the estimated cost of a post-production software defect of $4,000.[3] (This doesn’t include the headline-grabbing software bug at Knight Capital that caused the loss of $460 million in 45 minutes!)

3. Speed and improve software development.

Test managers report that broad use of the ISTQB Certification body of knowledge and glossary of software testing terms leads to better communication and greater efficiency among and across teams. Developers don’t want to fix the software bugs themselves – they report that fixing software bugs makes them feel frustrated, overwhelmed, burned out, resentful, and they want to quit. Moreover, 32% said they spend up to 10 hours a week fixing programming bugs, 16% spend up to 15 hours, and 6% spend up to 20 hours a week fixing programming bugs. Fifty-two percent of developers said they could use the time they spend hunting down and fixing software errors building new features and functionality instead.[4] This is why certifying your software testers has such a strong ROI: developers can focus on what they do best while certified testers can find software bugs much more efficiently than non-certified personnel.

4. Gain global acceptance.

With more than 750,000 testing certifications issued across 100+ countries, ISTQB software tester certification is the de facto global standard and, by far, the #1 global certification for software testers and other staff who help eliminate software bugs.  The American-English ISTQB exam created by ASTQB is available at test centers around the world – or you can take the exam online at home.

5. Get practical, everyday use.

ISTQB software tester certification focuses on practical applications of software testing that your testers and other technical staff need every day to find and eliminate programming errors. Covering everything from Agile testing to performance testing to security testing, ISTQB software tester certification offers the testing skills needed by your entire Agile, DevOps, or QA team so they can reduce software defects.

6. Improve employee motivation and retention.

The American Psychological Association (APA) found that in the absence of supervisor support for career development:

  • Less than half of employees say they are motivated to do their best at work (versus nearly 90% who report having supervisor support).
  • More than half say they intend to seek employment outside the organization within the next year.

As described below, the software testing certification career path from ASTQB offers turnkey career development that will help you motivate and retain your QA team. Not only will you reduce software errors, but you’ll develop a stronger, more resilient team.

7. Build a path for software QA skills development.

In addition to the career development levels (Foundation, Advanced, and Expert) and career paths (Test Manager, Test Analyst, Technical Test Analyst), ASTQB offers specialist skills such as Agile testing, mobile testing, security testing, test automation, performance testing, usability testing, automotive testing – and more – that improve the abilities of your entire QA team to find and eliminate programming errors.

8. Gain trust.

ASTQB offers software tester certification as a non-profit, volunteer-led organization. The certifications are based on modern standards that have been developed by more than 100 global software testing experts. ASTQB consists of software testing experts who volunteer their time to promote software quality in the United States and globally.

9. Improve cost-effectiveness.

ISTQB doesn’t require recertification at most levels, nor require expensive courses. While we recommend ASTQB-accredited software testing training providers because of their proven quality in preparing testers for the exams, your employees may self study, use in-house trainers, or choose the ASTQB-accredited education – it’s up to you to decide on the best training that will lead to certification and reducing software bugs.

10. Get additional potential savings.

Your company may be able to qualify for lower insurance costs when you hire ISTQB Certified Software Testers. For example, Hiscox Insurance Company qualifies technology insurance applicants based on whether their software testers are ISTQB Certified. Talk with your insurance company to see if you can qualify for discounts based on your employee’s certifications.
