Abstract: The vigorous development of mobile internet and the widespread application of high-tech have led to an increasing risk of leakage in national education examination. In order to effectively respond to risks, a design framework for the national education examination confidentiality knowledge testing system is proposed, which has functions such as confidentiality knowledge testing, score analysis, user management, and item management. The system provides targeted items for different types of confidential staff, effectively improving the effectiveness of confidentiality training and solving the confidentiality management challenges of the entire examination operation process. The spreading and application of the system will enhance the refined management level of specialized examination authority, and promote the sustained, healthy, and high-quality development of the national education examination confidentiality undertaking.
