Approved calculating devices are essential tools for the Fundamentals of Engineering (FE) exam. These devices assist examinees in performing complex calculations efficiently and accurately, covering topics such as mathematics, probability, statistics, and engineering economics. Permitted devices typically include specific scientific and graphing calculators, often with pre-approved model numbers listed by the exam provider. An example would be the Casio fx-115ES Plus or the TI-36X Pro.
The availability of a suitable calculating device contributes significantly to successful exam completion. It allows examinees to focus on problem-solving methodologies and engineering principles rather than tedious manual computations. This enhances both speed and accuracy, reducing the risk of errors and freeing up valuable time for tackling more challenging questions. Historically, the range of permissible devices has evolved alongside technological advancements, moving from slide rules to scientific and then graphing calculators, reflecting the increasing computational demands of engineering practice.
