What is the difference between “dynamic” vs. “static” text on proof plans or ID cards?

“Dynamic” text: This text is linked to your hhschools project fields. If your proof says FirstName, it will link to whatever is in your FirstName field in hhschools.  
“Static text: This text remains static, or the same, no matter what is in your hhschools project.
