So is everyone saying that if you apply for a government job ad had adjudication withheld on that charge. You can't get the job

This answer is not specific legal advice, nor does it establish an attorney client relationship. Generally, it depends on the requirements of the job. Some government positions would treat an adjudication withheld as a conviction that would need to be disclosed, and under some but not all circumstances that could disqualify you from the job. If you have not entered the plea or are concerned about qualifying for a specific position, you should talk to an attorney about your specific situation.

There are many government jobs that are technically available to individuals who have either pled no contest and have had adjudication withheld or pled guilty or were otherwise convicted in the sense that the plea, charge or conviction does not prohibit the agency from hiring an employee. However, there are some positions where this would be disqualifying. Also, depending on the job, if a security clearance is required or if the withheld adjudication has to be disclosed, the agency can take this into consideration in determining whether to hire the employee, even though it is not disqualifying.
