ISTQB Certified Tester AI Testing (CT-AI) [TSG_QAI]

OVERVIEW

The ISTQB Foundation AI  Tester Extension course extends the broad understanding  of testing acquired at Foundation Level to enable the role of AI Tester to be performed. 

This four-day tutor-led course includes lectures, exercises and practical work, as well as exam preparation. The examination is held a day or so after the course to allow time for revision. It is fully-accredited by UKITB on behalf of ISTQB and has been rated SFIAplus level 3 by the BCS.
