Insufficient testing or unqualified testers are frequently the root causes of inadequate software quality. In fact, the systematic use of solid test techniques is the exception rather than the rule in practical applications. The objective of the ISTQB® Certified Tester Program is to change this situation. All important testing issues are explained and simulated for training purposes. ISTQB® Certified Tester is a globally homogeneous program, which can be considered the benchmark for software testing. Hundreds of experts from more than 40 countries are continuously updating this program. Thanks to this close cooperation, international compatibility is always warranted.
