Do I need both fingerprint-supported background check and commercial background check?

If you have undergone a fingerprint-supported background check, DO NOT apply for a commercial background check. Fingerprint-supported background checks are valid until the family separates from AACPS. However; if you have undergone a commercial background check and you plan to chaperone/volunteer at an event which requires a fingerprint-supported background check, you MUST then submit to a fingerprint-supported background check (at your own expense).
