FE Exam Calculator Policy Checker

Instantly verify if your calculator model is approved by NCEES for the Fundamentals of Engineering (FE) exam.

Calculation Breakdown

Your Input: N/A

Policy Source: NCEES Official Calculator Policy

Logic: The tool checks if your input contains an approved model series name (e.g., “fx-115”, “fx-991”, “TI-30X”, “TI-36X”, “HP 33s”, “HP 35s”).

What is the best FE exam calculator?

The “best” FE exam calculator is not about having the most functions, but about complying with the strict NCEES calculator policy. To protect the integrity of the exam, NCEES limits the types of calculators examinees can use. Using a non-approved calculator can result in your exam being invalidated. Therefore, the best calculator is one that is on the approved list, and that you are extremely comfortable and efficient with. The most popular choices are often the Texas Instruments TI-36X Pro, the Casio fx-115ES Plus, and the Casio fx-991EX because of their powerful features and user-friendly interfaces.

NCEES Calculator Formula and Explanation

The NCEES policy is the “formula” for determining if a calculator is allowed. It’s not a mathematical formula, but a specific list of approved models. As of early 2026, the policy is as follows:

• Casio: All fx-115 and fx-991 models. The model name MUST contain “fx-115” or “fx-991”.
• Texas Instruments: All TI-30X and TI-36X models. The model name MUST contain “TI-30X” or “TI-36X”.
• Hewlett Packard: ONLY the HP 33s and HP 35s models are permitted.

Graphing calculators, calculators with wireless communication, or those with QWERTY keyboards (like the TI-89 or TI-Nspire) are strictly forbidden.

Approved Calculator Series

Brand	Approved Series/Model	Key Identifying String	Typical Use Case
Casio	fx-115 and fx-991	“fx-115” or “fx-991”	Powerful all-around with strong equation solving and matrix functions.
Texas Instruments	TI-30X and TI-36X	“TI-30X” or “TI-36X”	Very popular, especially the TI-36X Pro, known for its intuitive display.
Hewlett Packard	HP 33s and HP 35s	“HP 33s” or “HP 35s”	Often preferred by those familiar with Reverse Polish Notation (RPN).

Practical Examples

Example 1: The Compliant Student

Input: Sarah has a “Casio fx-115ES Plus” calculator. She types “fx-115es plus” into the checker.

Logic: The system detects “fx-115” in the input string.

Result: APPROVED. Sarah can confidently bring her calculator to the exam.

Example 2: The Non-Compliant Student

Input: Mike has a “TI-89 Titanium,” a powerful graphing calculator from his college calculus class. He types “TI-89” into the checker.

Logic: The system does not find any of the approved model strings. It specifically knows that graphing calculators are not allowed.

Result: NOT APPROVED. Mike needs to purchase a new, compliant calculator like one from the approved models list.

How to Use This FE Exam Calculator Checker

1. Locate Your Calculator’s Model Number: Find the model number printed on the front of your calculator.
2. Enter the Model: Type the full model name into the input field above.
3. Check Compliance: Click the “Check Compliance” button.
4. Review the Result: The tool will instantly tell you if your calculator is Approved or Not Approved based on the NCEES policy. The result will explain why the decision was made.

Key Factors That Affect Your Choice

While compliance is the first step, choosing the best FE exam calculator for you involves several factors:

• Familiarity: The best calculator is the one you know inside and out. Practice with your chosen calculator on all your study problems.
• Functionality: Ensure your calculator can handle matrix operations, equation solving, complex numbers, and statistical analysis efficiently.
• Display: A multi-line display (like on the TI-36X Pro) can make it easier to track complex calculations.
• Power Source: A solar-powered calculator with a battery backup provides peace of mind that it won’t die mid-exam.
• Ease of Use: The layout should be intuitive to you, minimizing the chance of hitting the wrong button under pressure.
• RPN vs. Algebraic: HP calculators often use Reverse Polish Notation (RPN), which is powerful but requires a learning curve if you’re used to standard algebraic entry.

Frequently Asked Questions (FAQ)

1. Why are graphing calculators like the TI-89 banned?

Graphing calculators are banned because their advanced features, like data storage and symbolic algebra, could provide an unfair advantage.

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

You will not be allowed to use it. Your exam may be invalidated, and you might have to forfeit your exam fee. It’s critical to check your model beforehand.

3. Is there a calculator provided at the testing center?

Yes, a digital on-screen calculator modeled after the TI-30X IIS is available. However, it is much slower to use than a physical, handheld calculator. You should bring your own approved device.

4. Can I bring two approved calculators?

Yes, many people bring a primary calculator and a backup (also an approved model) just in case of battery failure or other issues.

5. Is the TI-36X Pro the best FE exam calculator?

It is widely considered one of the best and is extremely popular due to its powerful features and intuitive multi-line display. However, the “best” choice is still a matter of personal preference and familiarity.

6. Does the NCEES policy ever change?

Yes, the list of approved calculators is reviewed annually. Always check the official NCEES website for the most current policy before your exam date.

7. What’s the difference between the Casio fx-115 and fx-991 models?

They are very similar in functionality. The fx-991 series often has slightly more features, such as additional scientific constants or unit conversions, but both are excellent choices.

8. Should I learn RPN for the HP 35s?

Only if you have significant time to practice and find it more efficient. For most candidates, sticking with a familiar algebraic calculator (like a TI or Casio) is a safer and faster strategy.
