4 Stat 125: SAS Certification 2 (1 credit) Book: Sharpening Your SAS Skills and SAS Certification Prep Guide: Advanced Programming - SAS Publishing Stat 125 is a one credit hour class taught the second block of Fall and Winter semesters, which was created for the purpose of exposing students to the materials needed to pass the SAS Advanced Programming Certification Exam. **Note that we will not teach you all that is needed to pass the exam. In fact, we will be teaching you very little. Instead, this course should be thought of as an independent study course with resources available to help you in your own study by e.g., outlining what is expected to pass the exam, explaining the types of questions that SAS typically asks on these exams, and answering questions you may have as you work through the SAS Certification Prep Guide alone or with friends. SAS Certified Advanced Programmer Exam A student completing Stat 125: SAS Certification 2 will be prepared to pass the SAS Certified Advanced Programmer Exam by demonstrating they can use SAS to: 1. use advanced DATA step programming statements and efficiency techniques to solve complex problems. 2. write and interpreting SAS SQL code. 3. create and use the SAS MACRO facility. SAS Certified Advanced Programmer certification represents the upper echelon of SAS programmers. Those who earn the advanced programming credential have demonstrated a high level of proficiency in SAS programming expertise and are a much sought after commodity in the global job market.
