ISTQB Certification: Complete Exam Study Material with Mock Test

What is ISTQB?

Full form of ISTQB is “International Software Testing Qualifications Board.” It offers internationally recognized certifications called “ISTQB Certified Tester.”

Why should I take the certification? Is there any market value to the certification?

This is a very controversial topic and can be debated till death.

But here are a few pointers which might assist you in your decision.

  • Foremost nothing beats EXPERIENCE. No certification can provide the exposure and training you get while working on real time projects. PERIOD!
  • If you are a fresher, or are from a non-technical background and trying to get a job in the software industry, certification will HELP. Just think about it, as an employer, I do not have any other parameters to judge your technical caliber, so certification is a good start point.
  • If you are an experienced professional and looking for a job change, a certification will embellish your resume. More so, no matter how rich your experience may be, there will always be some new area of QA that you will learn while studying for the certification. But do not think that you will get a JOB just based on the certification.
