At the fundamental awareness level, individuals are expected to have a basic understanding of SAS software and its syntax. They should be familiar with simple data manipulation techniques and basic statistical procedures. However, their knowledge is mostly theoretical and they may need guidance to apply it in practice.

Novices can write simple SAS programs and import/export raw data files. They can perform basic data cleaning and validation tasks, and use SAS functions. While they can apply their skills to solve simple problems, they still require supervision for more complex tasks.

Intermediate users are proficient in using PROC SQL for data manipulation and can create and manipulate SAS datasets. They understand advanced data manipulation techniques and SAS macros, and can perform complex statistical analyses. They can work independently on most tasks but may need assistance with highly complex problems.

Advanced users can use SAS/GRAPH for data visualization and automate tasks using SAS macros. They understand advanced statistical procedures and can optimize SAS code for performance. They can handle large datasets and work independently on complex tasks, providing solutions that are efficient and effective.

Experts can use SAS Enterprise Guide and SAS Studio proficiently. They can develop and implement complex SAS solutions, and understand advanced SAS programming techniques. They can integrate SAS with other technologies and troubleshoot and resolve complex SAS issues. They are capable of working independently on any task, regardless of complexity.
