Going further and obtaining a master's degree in civil engineering and a PE (professional engineer) license from an ABET accredited program is common for acquiring management positions in certain companies, taking direct control of projects and to be able to sell their services publicly. Most courses taken by civil engineers deal with mathematics, science, physics, statistics, mechanics, and systems. Civil engineers need certain skills to be able to do their jobs efficiently and correctly. They need to make decisions because they have to make choices about safety and financial costs when working on a project. Leadership skills are necessary because they take full responsibility for projects and have control over supervisors, managers, technicians, and others. Mathematical skills are useful because civil engineers use them to solve problems and design plans for projects using trigonometry and calculus. Organizational skills are key because they need to be able to monitor progress in the workplace and make sure everything is going according to plan. Problem-solving skills are essential because civil engineers work on highly complex projects that have many different variables that will naturally cause complications along the way. Civil engineers will also need writing skills because they will need to provide project reports, communicate with team members, and communicate
