and Full-Scope (Lifestyle) polygraphs. While a positive SSBI is sufficient for access to SCI-level information, polygraphs are routinely administered for "staff-like" access to particular agencies. If issues of concern surface during any phase of security processing, coverage is expanded to resolve those issues. At lower levels, interim clearances may be issued to individuals who are presently under investigation, but who have passed some preliminary, automatic process. Such automatic processes include things such as credit checks, felony checks, and so on. An interim clearance may be denied (although the final clearance may still be granted) for having a large amount of debt, having a foreign spouse, for having admitted to seeing a doctor for a mental health condition, or for having admitted to other items of security concern (such as a criminal record or a history of drug use.). When security concerns arise for an individual, which could bar them from holding a security clearance, adjudicators may also look at the Whole-Person Concept as a source of potential mitigation so that the person may still be granted a security clearance. The high-level clearance process can be lengthy, sometimes taking a year or more. In recent years, there has been an increased backlog of cases which has been attributed to the economic climate. The long time needed for new appointees to be cleared has been cited as hindering the presidential transition process. Security briefings In the US, once the clearance is granted, the candidate is briefed on "the proper safeguarding of classified information and on the criminal, civil, and administrative sanctions that may be imposed on an individual who fails to protect classified information from unauthorized disclosure." They are also required to sign an approved non-disclosure agreement (e.g., form SF-312). High-level clearances are reviewed periodically and any "adverse information" reports received at any time can trigger a review. When a cleared person leaves their job, they are often "debriefed"—reminded of their ongoing obligations to protect the information they were allowed to see, and the possible consequences should they fail to uphold those obligations. According to NISPOM Chapter 3, newly cleared employees are required to receive an initial security briefing before having access to classified information. This training helps them understand the threat, risks to classified information, how to protect the classified information, security procedures and duties as they apply to their job. This training is followed up by refresher training that reinforces
