Are parole guidelines different from state to state?

In the US, each state has its own corrections policies for their respective prison systems. This is because the US Constitution is set up to allow states to handle all powers not granted to the Federal government. With that in mind, states create policies for parole that meet their needs. There is one common thread, however, that all states agree about. That policy is this: anyone on parole who breaks the parole "rules", will be sent back to prison and their parole is revoked.
