While most iPads can be upgraded to the latest operating system, iPadOS 15, some are stuck at an earlier generation of the operating system. Apple leaves devices behind when they don't have the hardware that's necessary to smoothly run the new operating system.
Consult the chart below to find out the latest version of iOS or iPadOS that your tablet supports. To identify which iPad model you own, go to Settings > General > About. There you will find the "Model Name" and "Model Number."
