The decision-making process by which security clearance decisions are made is one that affects millions of employees and contractors working in the federal government and the defense industry. Unfortunately for applicants seeking a security clearance, and the organizations that sponsor them, any insights into this decision-making process are not validated or codified. For the Department of Defense (DoD) and other federal agencies, the issue of whom to trust with access to classified information is complicated by the complexity of each individual case and the potential for falsification(s) by applicants. This project seeks to use statistical methods by which the decision-making process can be codified. Best practices for applicants and sponsoring organizations will be developed in concordance with the results of these findings.
