The phrase identifies a specific class of computing devices permitted for use during the Principles and Practice of Engineering (PE) examination. These devices typically feature capabilities suited to engineering calculations but exclude advanced functionalities such as Computer Algebra Systems (CAS), graphing abilities beyond basic functions, and wireless communication capabilities. For instance, a standard scientific calculator with trigonometric, logarithmic, and statistical functions that lacks programmable memory beyond a limited number of storage registers would likely fall under this classification.
The availability of such tools provides examinees with the means to efficiently perform complex calculations required for solving engineering problems within the allotted exam time. Their standardized nature ensures a level playing field, mitigating advantages some candidates might otherwise gain through access to more powerful or specialized devices. The establishment of approved models has evolved over time, reflecting advancements in calculator technology while maintaining the integrity of the examination process. Historically, permitted devices have progressively increased in sophistication, provided they adhere to established limitations.
