What are FE Exam Approved Calculators?

FE exam approved calculators are a specific, limited list of calculator models that the National Council of Examiners for Engineering and Surveying (NCEES) permits for use during the Fundamentals of Engineering (FE) exam. To maintain the integrity of the exam and ensure no candidate has an unfair advantage, NCEES prohibits devices with advanced communication, text-editing, or programming capabilities. This means your powerful graphing calculator from college, like a TI-89 or Nspire, is not allowed.

The NCEES Calculator Policy Explained

The “formula” for calculator approval is not a mathematical one, but a set of rules defined by NCEES. The policy is straightforward: only certain models from three specific brands are permitted. Any calculator model not explicitly on this list cannot be brought into the testing room.

Variables of the Policy

Variable Meaning Unit / Type Typical Range
Brand The manufacturer of the calculator. Text Casio, Texas Instruments, Hewlett Packard
Model Series The specific family name in the model number. Alphanumeric fx-115, fx-991, TI-30X, TI-36X, HP 33s, HP 35s
Approval Status The binary outcome of whether the model is allowed. Boolean Approved / Not Approved

Practical Examples

Understanding the naming conventions is key. Here are two practical examples:

  • Example 1 (Approved): A student has a “Casio fx-115ES PLUS”. Because the model name contains “fx-115”, it is approved for the exam.
  • Example 2 (Not Approved): An engineer wants to use their “Texas Instruments TI-84 Plus”. Although it’s a Texas Instruments calculator, its model name does not contain “TI-30X” or “TI-36X”. Therefore, it is not approved.

Key Factors That Affect Calculator Approval

  • Correct Brand: The calculator must be a Casio, Texas Instruments, or Hewlett Packard. No other brands are allowed.
  • Model Series is Crucial: The most important factor is the model prefix. For Casio, it must be “fx-115” or “fx-991”. For TI, it must be “TI-30X” or “TI-36X”.
  • No Advanced Features: Calculators with features like a QWERTY keyboard, wireless communication, or the ability to store extensive notes are universally banned.
  • HP Models are Specific: Unlike Casio and TI which allow whole series, for HP, only two specific models are approved: the HP 33s and HP 35s. No other HP models are permitted.
  • Suffixes Usually Don’t Matter: For Casio and TI, suffixes like “Pro”, “Plus”, “ES”, or “MS” after the main series name generally do not affect approval. The key is the prefix. For help choosing, read about the best calculators for engineers.
  • Annual Review: NCEES reviews the policy annually, so it’s always good to check the latest rules before your exam date. Our tool is updated with the latest information.

Frequently Asked Questions (FAQ)

What happens if I bring a non-approved calculator to the exam?

You will not be allowed to use it. The proctors will confiscate it, and you will have to take the exam without a calculator or use the basic on-screen version provided.

Is the “Casio fx-991EX ClassWiz” approved?

Yes. Since its model name contains “fx-991”, it falls under the approved Casio series.

Is the “TI-36X Pro” the best FE exam approved calculator?

Many consider it one of the best due to its powerful features like a multi-line display and built-in solver functions, while still being on the approved list. Check out a review of the TI-36X Pro.

Can I bring two approved calculators?

You are allowed to bring one NCEES-approved calculator into the testing room. Spare calculators must be stored with your personal belongings.
