What are your biggest worries if Trump does away with the US Department of Education?

I’m looking for opinions based on facts regarding what can or will change in practice in the states.

Education is primarily run and funded at the state level. Even a lot of curriculum decisions are at the state level.

The constitutional decisions will still be in force unless they get overturned. Some of them get worked around anyway even today.

What type of monitoring does the department do now to ensure states are meeting standards? What is the punishment if the states don’t meet standards?
