Final answer:
Mandatory referrals to OPM regarding suitability are made in certain circumstances, such as criminal convictions or serious misconduct.
Step-by-step explanation:
OPM (Office of Personnel Management) is responsible for ensuring the suitability of individuals applying for federal employment. Mandatory referrals to OPM regarding suitability are made in certain circumstances, such as when an individual has a criminal conviction or is found to have engaged in serious misconduct that may impact their ability to perform the duties of the job.
For example, if a job requires access to classified information, and an applicant has a criminal record that includes convictions for espionage or treason, it would be mandatory to refer the case to OPM for further evaluation.
Other circumstances that may require mandatory referral to OPM include instances of financial irresponsibility or violations of laws pertaining to drugs or alcohol.
