Best Software Testing Certification: A Comparison There are several software testing certifications available. Which is the best software testing certification for you and your company? Below is a comparison of three software testing certifications using their entry level testing certification as a starting point: Certified Tester Foundation Level (CTFL) from ISTQB, the International Software Testing Qualifications Board Certified Software Tester (CSTE) from Software Certifications (a division of the Quality Assurance Institute) Certified Software Test Professional (CSTP) from International Institute for Software Testing (a division of Software Dimensions Consulting and Training, Inc.) Below is the comparison as we seek to answer which is the best software testing certification for you. How do the software testing certifications compare? Which is the best software testing certification? Not for Profit or For Profit? ISTQB is a not-for-profit organization, as its U.S. board, ASTQB. The other two certifications are from private, for-profit companies. Volunteer Board for U.S. In the U.S., the not-for-profit volunteer board is ASTQB, the American Software Testing Qualifications Board. The other two certifications do not have volunteer boards. (Related note: See why you should take your ISTQB exam through ASTQB.) Ranking Based on Number of Testing Certifications It is estimated that ISTQB is by far the #1 software testing certification organization based on the number of certificates awarded. The other two organizations no longer publicly disclose the number of certificates issued, but it is estimated that CSTE has more usage than CSTP. ISTQB reports more than 570,000 software testing certifications globally, while it is estimated that CSTE has less than 20% of ISTQB’s industry usage, and CSTP has less than 5% of ISTQB’s industry usage. Certification Course Sales and Required Fees ISTQB does not sell training courses directly; instead, you may choose the education that works best for you, be it self study or the use of a third party training provider (ASTQB does accredit training courses offered by third parties in the U.S. to ensure quality if you do choose a training provider, but their use is not mandated). The other two certification companies sell training directly. All three organizations offer a free body of knowledge, but ISTQB’s is much more comprehensive in size. ISTQB also offers a free glossary of software testing terms, as well as free sample exam questions and answers. Finally, ISTQB also has much lower required fees (e.g. the exam fee) than the for-profit organizations. Recertification Requirement ISTQB does not have a recertification requirement for the entry-level (Foundation) or advanced certifications. Both of the for-profit organizations require recertification every three years that requires payment. It should also be noted that ISTQB’s U.S. Board, ASTQB, offers additional, free benefits for those certified through ASTQB. These include free career information, local software quality sponsorships, podcasts, webinars, white papers, videos, and more.
