What are PE Exam Approved Calculators?
PE exam approved calculators are specific models of handheld calculators authorized by the National Council of Examiners for Engineering and Surveying (NCEES) for use during professional engineering licensure examinations. Unlike university exams where diverse devices might be allowed, the NCEES maintains a strict policy to ensure fairness and exam security.
Candidates preparing for the Principles and Practice of Engineering (PE) exam must select a device from the limited list of pe exam approved calculators. Using a non-approved device can lead to immediate disqualification and removal from the testing center. These calculators are typically non-programmable and lack communication capabilities, preventing the storage of prohibited notes or external communication during the high-stakes assessment.
The primary reason for these restrictions is to maintain a level playing field. If one candidate used a powerful graphing calculator while another used a basic scientific one, the disparity in solving complex matrices or integration could skew the results. Therefore, understanding the nuances of pe exam approved calculators is the first step in any engineer’s exam preparation journey.
PE Exam Approved Calculators Formula and Mathematical Explanation
While there isn’t a single “math formula” for approval, the NCEES uses a criteria-based derivation to determine which devices qualify as pe exam approved calculators. The primary factors include logic processing, memory volatility, and input methods.
We can represent the “Suitability Score” (S) for a specific PE discipline using a weighted formula:
S = (P × w1) + (E × w2) + (C × w3)
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| P | Power Rating (Math depth) | Scale 1-10 | 5 – 10 |
| E | Efficiency Factor (Input speed) | Scale 1-10 | 6 – 9 |
| C | Compliance Binary | 0 or 1 | 0 (No) / 1 (Yes) |
| w1, w2, w3 | Weighting coefficients | Percentage | 0.1 – 0.5 |
For example, a Civil Engineering student might prioritize the “Equation Solver” capability (Power), whereas an Electrical Engineering student might value complex number manipulation. All pe exam approved calculators must have C=1.
Practical Examples (Real-World Use Cases)
Example 1: The Civil Engineering Candidate
An examinee chooses the TI-36X Pro for the Civil PE exam. This model is one of the most popular pe exam approved calculators.
Inputs: Model = TI-36X Pro, Discipline = Civil.
Output: Compliance = Approved, Suitability Score = 95/100.
Interpretation: The TI-36X Pro handles the unit conversions and solver functions required for structural analysis efficiently, making it an ideal choice for this discipline.
Example 2: The Electrical Engineering Candidate
An examinee attempts to bring a TI-84 Plus.
Inputs: Model = TI-84 Plus, Discipline = Electrical.
Output: Compliance = PROHIBITED, Suitability Score = 0.
Interpretation: Even though the TI-84 is powerful, it is not on the list of pe exam approved calculators. The candidate must switch to a Casio fx-115ES Plus or similar to avoid disqualification.
How to Use This PE Exam Approved Calculators Calculator
Follow these steps to ensure you are selecting the best tool for your exam day:
- Select the Brand: Choose from Casio, HP, or TI. Our tool filters based on the latest NCEES pe exam approved calculators list.
- Select the Model: Find your specific model number. Pay close attention to suffixes (e.g., “Plus” or “ES”).
- Choose Your Discipline: Select your engineering branch. The calculator adjusts the suitability score based on the specific math requirements of that exam.
- Analyze the Results: Check the “NCEES Compliance Status” immediately. If it says “APPROVED”, you are safe to proceed.
- Review the Chart: Look at the Power vs. Speed chart. A higher power rating is better for complex equations, while a higher speed factor suggests a more intuitive interface.
Key Factors That Affect PE Exam Approved Calculators Results
- Memory Volatility: NCEES requires that pe exam approved calculators do not have “prohibited” memory features. This is why graphing calculators are banned.
- Solar vs. Battery Power: For long 8-hour exams, having a dual-power source (solar + battery) is a critical reliability factor.
- Button Tactility: Speed is essential. High-quality buttons prevent double-taps or missed inputs during timed pressure.
- Natural Display: Models like the Casio fx-115ES Plus show fractions and square roots as they appear in textbooks, reducing manual transcription errors.
- Equation Solvers: The ability to solve 3×3 matrices or quadratic equations can save minutes per problem, which is vital for pe exam approved calculators.
- Historical Usage: Some engineers prefer the RPN (Reverse Polish Notation) of the HP 35s, though it has a steeper learning curve than TI models.

Frequently Asked Questions (FAQ)
1. Can I bring two pe exam approved calculators to the test?
Yes, NCEES generally allows you to bring a backup calculator into the testing room, provided both are on the pe exam approved calculators list.
2. Is the TI-36X Pro better than the Casio fx-115ES Plus?
Both are excellent pe exam approved calculators. The TI-36X Pro is often praised for its menu system, while the Casio is noted for its “Natural Display” and ease of use with fractions.
3. Why are graphing calculators not allowed?
Graphing calculators have large storage capacities and can communicate via infrared or cables, making them a security risk for standardized testing.
4. Does the NCEES list change every year?
The list of pe exam approved calculators is reviewed annually but rarely changes significantly. Always check the official NCEES website for the most current list before your exam.
5. Can I use a calculator with a QWERTY keyboard?
No, devices with QWERTY keyboards are explicitly banned and do not qualify as pe exam approved calculators.
6. What happens if my calculator dies during the exam?
Proctors will not provide backups. This is why we recommend bringing a spare from the pe exam approved calculators list.
7. Is the HP 35s still approved even though it is discontinued?
Yes, as of the latest update, the HP 35s remains on the list of pe exam approved calculators, though it is becoming harder to purchase.
8. Are “solar only” calculators allowed?
Yes, but they are risky in testing centers with dim lighting. Opt for dual-power pe exam approved calculators instead.
