Many employees and suppliers are required to be certified on a regular basis to perform their duties at the airport. This involves both re-training and re-examination. This module organises, keeps track of and manages access to the educational materials. It allows instructors to develop, manage, deliver, correct and grade exams, quizzes, assessments and certification tests plus surveys and questionnaires. Capabilities range from rich text and graphics in test questions to random question selection from multiple question pools to detailed reporting on test performance.
