Do I need a background check from the state or federal level to get a work permit in Thailand?

An American seeking a work permit in Thailand is inquiring about the necessity of obtaining a background check, whether it should be at the state or federal level. Responses from the community suggest that a background check is generally not required unless the individual is teaching. Several commenters also mention that the employer is likely to provide guidance on requirements, with one person noting that they obtained their background check from the police headquarters in Bangkok.
