The course objective is to enable students to build upon the knowledge and lessons learned in the Personnel Security Adjudications Course (PSAC). This course covers personnel security case studies and issues that a senior adjudicator may encounter in the day-to-day work environment. The security eligibility determinations are based on review of Personnel Security Investigations (PSI), which contain significant derogatory information. The course covers the review of significant derogatory information, requesting additional information, evaluation of significant derogatory and/or additional information, writing Statements of Reason (SOR), reviewing rebuttals, making final determinations, and reviewing reconsideration requests.
