In CA the fingerprint check should only return disqualifying convictions, not a complete rap sheet. DUI is not a disqualifying conviction for a teacher. As such, I don't think the DUIs will appear here. If the district also checks public records, they might discover this and it MIGHT be an issue for them ... maybe. But, I have arrested a few teachers over the decades for DUI and other offenses (including marijuana sales) and all of them are still teaching. So, I wouldn't worry too much.
