The ISTQB® Certified Tester program provides certification for software testers internationally.
Program can be divided into: Core Foundation Level certification, Advanced Level certifications, Specialist certifications and the Expert Level certifications.
For all levels, international working groups develop and maintain internationally uniform curricula and exams.
One of the core principles of the program is a strict separation between the administration of exams and the training to those who would like to prepare for the exam in ISTQB® compliant courses.
This is not true of other testing and/or quality assurance organizations.
