By taking ASTQB's official ISTQB American English exam, you are demonstrating your ability to communicate with their U.S. teams. That's a big deal to U.S. companies because they rate "effective communication" as a top skill when hiring employees and choosing software testing services.
Here is a bonus when you take your ISTQB exam through ASTQB and AT*SQA: You also earn points toward your Testing Tiers™ software tester ranking. (Note: We also add you to ISTQB's successful candidate register – only ASTQB & AT*SQA can add you to both lists.)
Testing Tiers™ lets you see how you compare to other software testers. It's also a great way for employers to rank job candidates.
