Generally no. An employer cannot use your credit score or any information in your credit report to make an employment decision. There are exceptions. For example, if you work for the Department of Justice, as a peace officer, in a bank or have constant access to deposits of $10,000 or more (ie check cashing) or handle personal sensitive information then your credit report can be used as a basis to make decisions.
It is important that you know that before your credit information is pulled your employer/potential employer must give you an authorization form and you must sign it and approve the request.
