I hoped to hear back from you, but as I didn't, I will provide you with an answer to what I think you want to know. If it turns out that I didn't guess correctly, then you can always reply here on this question thread and refine your question, and I'll be happy to expand my answer.
I think you're wondering whether your daughter can miss court. The answer is that if she is not there, or if she does not have a lawyer to be there on her behalf, a warrant will issue for her arrest. If this is her first arrest and it's a low level shoplifting charge, she ought to be able to come out of this without a criminal record, assuming she takes her court obligation seriously. Nobody's going to be looking to do her any favors if she blows off her court date.
She has some options: she can go to court and reschedule her test. She can hire a lawyer and have a lawyer go to court on her behalf, have him explain to the judge about the exam and then schedule a new date for her. She can call the clerk of the court and find out how to reschedule her court date for a date where she has no test.
How to change the court date varies from jurisdiction to jurisdiction, but the clerk of the court will know what she has to do to change the date and will explain the process to her.
If she does none of the suggestions above, a warrant for her arrest will issue and the prosecutor may feel she's a poor risk for the sort of disposition that would keep this charge off of her record. She needs to take this charge seriously, if she expects her college degree to be worth something to her. A theft conviction indicates a dishonest nature, and it is the type of a criminal offense, even on a misdemeanor level, that employers shy away from most.
She should get the date changed and you should see to it that she's represented by counsel on her court date so that she doesn't take the easy way out of the case and give herself a criminal conviction.
