The sample test is designed to give the candidate an idea of the content and format of the questions that will be on the certification exam. Performance on the sample test is NOT an indicator of performance on the certification exam. This should not be considered an assessment too

Courses and publications are offered to help you prepare for the certification tests. The courses are recommended, but not required, before taking a certification test.

Please note that all courses listed in this section are also offered as Instructor-Led Online (ILO) courses. The course number is slightly different – For example, course CM20 would be CMW20 for the ILO version.
