Our INF testing code is exclusively used for students who have graduated from NTSOC and is not given out to graduates from other schools. This code allows NTSOC to provide private testing for our students that is not available to the public. If you were a graduate of NTSOC and need the INF code, please see the paperwork that was emailed to you at graduation, or give us a call at 719-574-5562 ext 242, or email us at cnamail@ntsoc.com. Testers that are not NTSOC graduates and manage to obtain our INF code elsewhere will be removed from the testing roster by Credentia.
