Do I need to tell my state department of education and/or school district about an OWI?

you need to speak to the leaders of your collective bargaining unit for what your CBA requires. Then contact your licensing agency in Lansing for clarification on self reporting requirements...is it all criminal convictions, just felonies or assaultive crimes, etc.? My understanding (which may not be current) is that self-reporting is required for all criminal convictions. when in doubt it is best to self-report even misdemeanors because failure to comply with self-reporting obligations is grounds for suspension or even revocation of license even if the offense that is not reported does not require suspension or revocation of licensure. the non-reporting is very serious licensing violation. OWI is a criminal conviction.

This is not just a traffic offense it is a criminal offense and probably should be reported.

Chances are you are required to either by State employment regulations or your union contract.

This is a misdemeanor, not a traffic offense. If you are required to report misdemeanors, you should do so. If you choose not to, and they run a background check, it will show up and you could be fired.

It is certainly a criminal offense. Whether you have to report is up to your organization. I would believe yes.

No. You will need to disclose when you seek to renew certification from the state.
