Already Know the Basics? Jump Right In
If you're already familiar with key mainframe concepts and just want to sharpen a specific skillset, these individual modules are for you.
- Pick focused topics like COBOL, JCL, Db2, REXX, and more
- Shorter, skill-based modules from the full Mainframe Starter Program
- Ideal for refreshers, transitions, or targeted upskilling
Each module is designed to be clear, focused, and practical — giving you just what you need to move forward, without confusion or overwhelm.
