Hello, SAS® Certified Advanced Programmer for SAS®9 page says: Candidates who earn this credential must have a SAS Certified Base Programmer for SAS®9 credential and then take and pass the SAS Advanced Programming for SAS®9 exam. But Base Programmer exam includes topics from: SAS Programming 1: Essentials SAS Programming 2: Data Manipulation Techniques While Clinical Trials Programmer exam includes topics from: SAS Programming 1: Essentials SAS Programming 2: Data Manipulation Techniques SAS Macro Language 1: Essentials SAS Report Writing 1: Essentials Statistics 1: Introduction to ANOVA, Regression, and Logistic Regression Does that mean that I can take Clinical Trials Programmer first and then Advanced Programmer exams not having Base Programmer credential? Or, having a Clinical Trials credential, I have to take Base exam again to proceed with Advanced one?? Best Regards, Dmitry
