On September 1, 2014, the International Software Certification Board (ISCB) announced their approval for release of the Software Testing Body of Knowledge v14 (STBOK). The STBOK covers the requisite materials for the Certified Associate in Software Testing (CAST) and Certified Software Tester (CSTE) certification exams. The Software Testing Body of Knowledge is the knowledge basis for the Certified Manager of Software Testing (CMST). The STBOK will be phased in over the next several months eventually replacing the Software Testing CBOK.
