What is the NCEES Calculator Policy?

The NCEES calculator policy specifies the only calculator models that are permitted for use during the Fundamentals of Engineering (FE) and Professional Engineering (PE) exams. The primary reason for this policy is to maintain exam security and integrity. NCEES prohibits devices with extensive communication capabilities, such as text entry, wireless connectivity, or access to external memory, to prevent any possibility of cheating. Therefore, the list of calculators allowed on the fe exam is limited to specific non-programmable, non-graphing scientific models that have been vetted by the board. This policy ensures a level playing field for all examinees.

This policy is critical for anyone preparing to take the exam. Bringing a non-compliant calculator will result in it being confiscated before you enter the testing room, forcing you to rely solely on the on-screen digital calculator, which may be unfamiliar and slow you down. Understanding the rules regarding the calculators allowed on the fe exam is a simple but vital part of your test preparation.

The NCEES Calculator Approval “Formula” Explained

There isn’t a mathematical formula for approval, but rather a set of strict rules based on the model name. The logic for checking the calculators allowed on the fe exam is straightforward and can be broken down into steps for each major brand.

The check follows this logic:

  • For Casio: The model name MUST contain “fx-115” OR “fx-991”.
  • For Texas Instruments: The model name MUST contain “TI-30X” OR “TI-36X”.
  • For Hewlett Packard: The model name MUST be EXACTLY “HP 33s” OR “HP 35s”.

Our checker automates this process. For a comprehensive overview, consult our free FE practice exam resources.

Breakdown of NCEES approval criteria.
Variable Meaning Unit Requirement for Approval
Brand The manufacturer of the calculator. Text Must be Casio, Texas Instruments, or HP.
Model String The specific model identifier on the calculator. Text Must contain an approved keyword (e.g., ‘fx-115’, ‘TI-36X’) or be an exact match (e.g., ‘HP 35s’).

Practical Examples (Real-World Use Cases)

Let’s apply the policy to common scenarios to clarify which calculators allowed on the fe exam make the cut.

Example 1: The Student with a Common Calculator

  • Input Brand: Casio
  • Input Model: fx-115ES Plus
  • Analysis: The brand is Casio, and the model name “fx-115ES Plus” contains the required string “fx-115”.
  • Output: APPROVED. This is one of the most popular calculators allowed on the fe exam.

Example 2: The Engineer with a Graphing Calculator

  • Input Brand: Texas Instruments
  • Input Model: TI-89 Titanium
  • Analysis: Although the brand is approved, the model name “TI-89 Titanium” does not contain either “TI-30X” or “TI-36X”. Graphing and communication features are explicitly banned.
  • Output: NOT APPROVED. This calculator has features that are disallowed by the NCEES calculator policy.

How to Use This FE Exam Calculator Checker

Using this tool is designed to be fast and intuitive, giving you an instant verdict on your calculator’s compliance.

  1. Select the Brand: Choose your calculator’s manufacturer (Casio, Texas Instruments, or Hewlett Packard) from the dropdown menu.
  2. Enter the Model: Type the model number exactly as it appears on the front of your calculator. The check is not case-sensitive.
  3. Review the Result: The tool will immediately display a clear “APPROVED” or “NOT APPROVED” status.
  4. Check Intermediate Values: The cards below the main result confirm your inputs for verification. The policy year is also displayed for your reference.

This checker helps you avoid a common and preventable problem on exam day. Verifying your device is a key step in your strategy to pass the FE exam.

Key Factors That Affect Your Calculator Choice

While the list of calculators allowed on the fe exam is narrow, there are still differences between models that can impact your performance. Choosing the right one is a matter of strategic preference.

  • Familiarity: The best calculator is the one you know how to use. Don’t switch to a new model right before the exam. Practice with your chosen calculator for months.
  • Display Type: Models like the TI-36X Pro and Casio fx-115/991 series feature “natural” or “textbook” displays, showing fractions and equations as they appear in print. This can significantly reduce input errors compared to single-line displays.
  • Solver Functionality: The TI-36X Pro is well-regarded for its multi-equation solver, which can save a tremendous amount of time on certain problem types.
  • Power Source: Most approved calculators are dual-powered (solar with battery backup). Ensure your battery is fresh before exam day, or bring a compliant backup.
  • RPN vs. Algebraic Entry: The HP 33s and 35s models offer Reverse Polish Notation (RPN), which some experienced engineers find faster and more efficient. However, it has a steep learning curve and is not recommended for new users.
  • Cost and Availability: The Casio fx-115ES Plus and TI-30XS are generally the most affordable and widely available models. The TI-36X Pro and HP 35s are more expensive but offer more advanced features.

Frequently Asked Questions (FAQ)

1. Why is the NCEES calculator policy so strict?

The policy exists to protect the integrity of the exam. By standardizing the tools, NCEES ensures no examinee has an unfair advantage through calculators that can store text, execute complex programs, or communicate wirelessly.

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

Exam proctors will inspect your calculator. If it is not on the approved list, you will not be allowed to bring it into the testing room. You will have to use the on-screen calculator provided in the exam software.

3. Can I bring two calculators into the exam?

You may bring more than one NCEES-approved calculator into the exam room, which is a good idea in case your primary one fails. However, both must be on the approved list.

4. Is the TI-36X Pro the best of the calculators allowed on the FE exam?

Many consider the TI-36X Pro the best option due to its powerful solver, clear display, and robust feature set. However, the best calculator is the one you are most comfortable and proficient with. The Casio fx-115ES Plus is another top contender. For more comparisons, review our engineering career guide.

5. Do I need to clear my calculator’s memory?

The approved models have limited memory that is typically cleared when powered off. Proctors may inspect your calculator, but the models are chosen specifically because they don’t have large, permanent storage capabilities.

6. Is a physical calculator better than the on-screen one?

Yes. You will be much faster and more accurate using a physical calculator you have practiced with. The on-screen calculator should be considered a last resort. Relying on it will likely cost you valuable time.

7. Does the policy for calculators allowed on the FE exam ever change?

Yes, NCEES reviews the policy annually. However, the core models have remained consistent for many years. Always check the official NCEES website for the most current policy before your exam date.

8. Are any graphing calculators allowed?

No. All graphing calculators, like the TI-84 or TI-89, are explicitly forbidden because of their advanced programming and storage capabilities. The list of calculators allowed on the fe exam is restricted to scientific calculators.

What are Calculators Allowed on the FE Exam?

The **Calculators Allowed on the FE Exam** refer to the specific list and types of calculator models that the National Council of Examiners for Engineering and Surveying (NCEES) permits candidates to use during the Fundamentals of Engineering (FE) exam. NCEES maintains a strict calculator policy to ensure fairness and prevent the use of devices with unauthorized capabilities (like communication, extensive memory, or QWERTY keyboards).

Anyone preparing to take the FE exam must be aware of and adhere to this policy. Using a non-approved calculator can result in dismissal from the exam and invalidation of scores. Common misconceptions include thinking any scientific calculator is fine, or that programmable calculators are allowed if cleared – this is not the case; only specific models are permitted.

NCEES Calculator Policy Explained

The NCEES Calculator Policy is very straightforward: only certain calculator models are allowed. The policy is not based on features but on specific model numbers. As of recent updates, the policy generally includes:

  • Casio: All fx-115 and fx-991 models. Any Casio calculator must have “fx-115” or “fx-991” in its model name.
  • Hewlett Packard: The HP 33s and HP 35s models are allowed, but no other HP models.
  • Texas Instruments: All TI-30X and TI-36X models. Any Texas Instruments calculator must have “TI-30X” or “TI-36X” in its model name.

The policy aims to prevent access to calculators with features like:

  • QWERTY keypads
  • Wireless communication capabilities
  • The ability to store extensive text or formulas beyond what’s built-in
  • Camera or scanning functions

You must check the official NCEES website for the most current list before your exam, as the list of **Calculators Allowed on the FE Exam** can be updated.

Practical Examples

Example 1: Checking a Casio fx-115 ES Plus

A student has a Casio fx-115 ES Plus. They use the checker or refer to the NCEES policy. Since “fx-115” is in the model name, this calculator is allowed.

Example 2: Checking a TI-89 Titanium

Another student has a Texas Instruments TI-89 Titanium. This is a powerful graphing calculator. It does NOT have “TI-30X” or “TI-36X” in its name. Therefore, the TI-89 is NOT among the **Calculators Allowed on the FE Exam** and cannot be used.

Example 3: Checking an HP 50g

An engineer has an HP 50g graphing calculator. While powerful, only HP 33s and HP 35s are permitted. The HP 50g is NOT allowed.

  5. Always Verify: Regardless of the checker’s result, visit the official NCEES calculator policy page to confirm before your exam day.

Use the result as a preliminary guide. The final authority is always the NCEES website.

Key Factors That Affect Calculator Allowance

  1. Model Name/Number:** The most crucial factor. The model name must exactly match or belong to the series specified by NCEES (e.g., contain “fx-115”, “fx-991”, “TI-30X”, “TI-36X”, or be “HP 33s” or “HP 35s”).
  2. Brand:** Only Casio, HP, and TI have models currently on the allowed list. Other brands are generally not permitted.
  3. NCEES Policy Updates:** NCEES can update its list of **Calculators Allowed on the FE Exam** at any time. What was allowed previously might not be now, and vice-versa (though changes are infrequent).
  4. Prohibited Features:** Even if a model seems close, if it has features like a QWERTY keyboard, wireless, or extensive text storage, it’s likely not allowed (and NCEES bases its list on preventing these).
  5. Exam Center Discretion:** While NCEES sets the policy, the exam center proctors enforce it. They will check your calculator, and their decision on exam day is final based on their understanding of the NCEES rules.
  6. Physical Condition:** Calculators with missing parts, or that are significantly damaged or modified, might be questioned, even if the model is correct.

Understanding these factors helps in selecting the right calculator from the list of **Calculators Allowed on the FE Exam**.

Frequently Asked Questions (FAQ)

1. Can I use a graphing calculator on the FE exam?
No, most graphing calculators (like the TI-83, TI-84, TI-89, TI-Nspire CAS, HP 50g, etc.) are NOT among the **Calculators Allowed on the FE Exam**. Only the very specific models listed by NCEES are permitted.
2. What if my calculator model is very similar but not exactly on the list?
You should assume it’s not allowed unless it clearly fits the series descriptions (e.g., contains “fx-115”, “fx-991”, “TI-30X”, or “TI-36X”). If in doubt, get a confirmed allowed model or contact NCEES.
3. Do I need to clear the memory of my allowed calculator before the exam?
The allowed calculators have very limited memory that is typically cleared by resetting the device or removing batteries (if applicable). Exam proctors may inspect your calculator, and you should ensure it doesn’t contain prohibited information.
4. Can I bring two allowed calculators?
The NCEES policy generally implies one calculator, but check the latest NCEES Examinee Guide for rules on backup calculators. It’s best to bring one fully functional, approved calculator with fresh batteries.
5. Where can I find the official list of calculators allowed on the FE exam?
On the official NCEES website, under the “Exams” section, look for the calculator policy page: https://ncees.org/exams/calculator/.
