Do you know if you plead guilty and have a conviction or did you get it dismissed? You can usually go to the court's website and look up the case on your own and see. If it says dismissed, then all you need to do is be honest and list what happened on your applications for teaching or licensing and they will consider everything. If you don't list it and they find it, then they will deny you licensing and a job and you can possibly face charges for lying on an application. I called around to several school districts because I have been worried I will never be able to teach or work in my career field ever again, which is a consequence that is being faced and I'm trying to get my life back in order and eventually try to go back to teaching and show that this is most definitely not my typical behavior. That will take a lot of time more than likely and fortunately I have a wonderful husband who has stood by me. I am very lucky and it makes me look at people in a whole new way. Some are forgiving and some are not so likely when dealing with something like this.
Anyway, each of the school districts told me that if the charge was dismissed they just want to know about the incident because it will come up on background checks. They want you to be honest about it not try to get it expunged and deny it. They want you to show that you have learned from this terrible mistake in your life and that you have truly gotten help and are likely to never do something like it again. You will have to have some proof of this, like in your case, you have apparently gone through college and stayed out of trouble and probably beneficial to tell them more about how you have bettered yourself and learned from the situation rather than explaining why you did it in the first place. Also explaining other things you have done, such as community service, school activities, etc. will be helpful where they ask. And most school districts want to know those kinds of things on their applications or in the interviewing process about things you've done.
The other thing I was told (you should call the school district where you're attempting to seek employment) was that they want you to list it on your background check and teaching application forms so they know and are aware that something has happened, not to judge you. They also told me it is for Human Resources information and they do not pass on that information to any principal or anyone else. At least, they are not supposed to do that from what a couple of HR's managers told me. They will either recommend you for hiring or won't to a principal and that is it. So, if you are honest and can prove turn around since the incident, they are more likely to suggest you for the job. But if you lie, you will most definitely be ruled out!!!!!
