Not certain if you had a criminal defense attorney in your case, but you need to check with the attorney or the court to see if you were placed on a deferred probation or if your record is currently sealed from the public. Typically with juveniles convicted of a low level offense such as theft, the court will either seal your juvenile record so that it does not appear to future employers or even schools, or they may place you on a deferred adjudication so that the criminal offense will not appear so long as you comply with all court orders, such as making monthly payments to the store. If this is the case, then employers will not be able to see that you were charged and convicted of Theft.
