I think they are referring to something more often called 'corporate compliance'. It applies to government & not-for-profits as well.
In some organizations, people at a certain level & above need to complete/sign a questionnaire on an annual basis relating to their understanding of and compliance with the organization's 'business' ethics.
I would think that in the case of state-employed individuals, it would include questions about actions/attitudes which, if in place & (as importantly) understood & followed, help keep the state agencies 'beyond reproach'. I'm sure that your agency or the state has a rule about taking gifts from outside people with whom the state does business: usually that is prohibited completely, or above a certain (usually small) $$ amount. So, if the guy who rents copiers to your agency sends the people who work in the purchasing/contracts department a case of wine during the holidays, you are not supposed to accept it. Another example would be not using the department's petty cash fund to take the department out for an holiday luncheon: if you want to go to lunch to celebrate the holidays, you pay for it yourself. It might also include things that relate to equal-opportunity laws: if you are interviewing someone for a job, their age, sex, religion etc should not matter, as it should not matter in your interractions with co-workers.
That would be my guess. If this has not been done before, and is being called a 'quiz' to be given to all state employees, they are probably trying to gauge peoples' awareness of the rules as much as anything else. If 70% of the employees think it is okay for an outside company rep to take them to a $50 lunch, then the state's compliance/ethics office needs to re-evaluate how they are informing employees of the rules, before they even worry about whether they are being enforced.
Hopefully, most the 'right' answers will be apparent to you. But if for example they have a $$ amount relating to accepting small gifts from outside people, and you don't know what that amount is, the problem is more the state's educational process than yours. If it turns out to be something like this, where the questions relate to $$, there is a good chance that the most cautious/conservative answer is probably the right one, because you represent the government.
