Calculators Allowed On Pe Exam

Ensure your device is NCEES compliant and optimize your exam speed.

What are Calculators Allowed on PE Exam?

The calculators allowed on pe exam are a strictly defined set of battery-operated, non-communicating, handheld devices approved by the National Council of Examiners for Engineering and Surveying (NCEES). Every year, NCEES updates the list to ensure that no student has an unfair advantage through programmable memory or communication capabilities.

Who should use this guide? Any engineering professional or student preparing for the Principles and Practice of Engineering (PE) exam or the Fundamentals of Engineering (FE) exam. A common misconception is that any scientific calculator is permitted; however, using a non-approved device can lead to immediate disqualification and your exam results being nullified. Understanding the specific calculators allowed on pe exam is the first step in your exam preparation strategy.

Calculators Allowed on PE Exam Formula and Mathematical Explanation

While NCEES doesn’t provide a formula, we can quantify your readiness using the Exam Efficiency Metric (EEM). This measures how your choice of calculators allowed on pe exam combined with your experience impacts your solving speed.

The efficiency formula used in this tool is: EEM = (Feature_Weight * Practice_Factor) / Average_Time

Variable	Meaning	Unit	Typical Range
Feature_Weight	Built-in solver/matrix capabilities	Scale 1-10	5 (TI-30X) to 10 (TI-36X/HP 35s)
Practice_Factor	Logarithmic growth based on hours	Multiplier	0.5 to 1.5
Average_Time	Seconds per calculation	Seconds	20s to 120s

Practical Examples (Real-World Use Cases)

Example 1: The TI-36X Pro Power User

An engineer uses one of the most popular calculators allowed on pe exam, the TI-36X Pro. They have logged 50 practice hours and can solve a complex fluid mechanics equation in 30 seconds.
Result: Their Efficiency Score would be high (approx 92%), saving nearly 40 minutes over the 8-hour exam window compared to a novice user.

Example 2: The Last-Minute Switch

A candidate realizes their graphing calculator is not among the calculators allowed on pe exam and buys a Casio fx-115ES Plus the night before. With only 2 hours of practice and a slow solving time of 75 seconds per problem.
Result: Efficiency drops to 35%, potentially leading to “time-crunch” stress during the afternoon session.

How to Use This Calculators Allowed on PE Exam Calculator

1. Select your Model: Choose your device from the dropdown list. If your model isn’t listed, it is likely not among the calculators allowed on pe exam.
2. Enter Practice Hours: Be honest about how many hours you’ve actually used the device for engineering problems.
3. Estimate Speed: Time yourself solving a typical PE-level problem involving fractions, exponents, or unit conversions.
4. Analyze Results: Review your Efficiency Score and “Time Saved” to determine if you need more practice or a better-featured model.

Key Factors That Affect Calculators Allowed on PE Exam Results

• Internal Logic (RPN vs. Algebraic): The HP 35s uses Reverse Polish Notation. While powerful, it requires more practice hours to master than the TI-36X Pro.
• Matrix and Vector Capabilities: Some calculators allowed on pe exam handle 3×3 matrices easily, while others require manual entry, adding significant time.
• Equation Solvers: Models with built-in solvers allow you to input variables and solve for ‘x’, reducing algebraic error risks.
• Battery Life and Reliability: Dual-power (solar/battery) models are preferred to avoid mid-exam failures.
• Button Tactility: Physical feedback prevents double-entry errors, which are common under exam pressure.
• Screen Readability: Multi-line displays allow you to see the previous entry, which is vital for verifying long strings of calculations.

Frequently Asked Questions (FAQ)

Are graphing calculators allowed on the PE exam?

No, graphing calculators are strictly prohibited. Only specific non-graphing models are considered calculators allowed on pe exam.

Can I bring two calculators to the exam?

Yes, NCEES generally allows you to bring a backup, provided both are from the approved calculators allowed on pe exam list.

Does the Casio fx-991EX count as a calculator allowed on the PE exam?

Yes, the Casio fx-911 series is included in the approved Casio FX-115 and FX-991 sub-groups.

What happens if I bring a non-approved calculator?

Proctors will confiscate it before the exam begins. If found during the exam, you will be disqualified immediately.

Is the TI-84 on the list of calculators allowed on pe exam?

No, the TI-84 is a graphing calculator and is strictly forbidden for the PE and FE exams.

Why is the TI-36X Pro so popular?

It is widely considered the most advanced of the calculators allowed on pe exam due to its multi-line display and intuitive solver features.

Do I need to clear the memory before the exam?

Proctors may ask you to reset the device. Ensure you know the button combination to reset your specific model of calculators allowed on pe exam.

Are there restrictions on calculator covers?

Yes, covers, manuals, and cheat sheets must be removed and placed under your seat or in a designated area.
