What Calculator Can I Use on the FE Exam?

Navigating the requirements for the Fundamentals of Engineering (FE) exam can be stressful, and one of the most common questions prospective examinees have is: “What calculator can I use on the FE exam?” The NCEES (National Council of Examiners for Engineering and Surveying) has very specific rules about approved calculators to ensure a fair testing environment for all. Using a non-approved calculator can lead to serious consequences, including being dismissed from the exam. This guide provides a comprehensive overview of the NCEES calculator policy and helps you determine if your calculator is compliant.

Understanding the NCEES Calculator Policy

The NCEES FE exam calculator policy is designed to prevent candidates from gaining an unfair advantage through advanced computational capabilities. The core principle is that calculators must be basic in nature, focusing on standard mathematical functions rather than complex programming, graphing, or data storage/communication. This means most standard scientific calculators are acceptable, while advanced graphing calculators or those with specialized functions are typically prohibited.

Who Needs to Know This Policy?

  • All FE Exam Candidates: Regardless of your engineering discipline, you must adhere to the calculator policy.
  • Students Preparing for the FE Exam: It’s crucial to know this policy well in advance of your exam date to purchase or familiarize yourself with an approved model.
  • Educators and Academic Advisors: Providing accurate information about the FE exam process is vital for student success.

Common Misconceptions about FE Exam Calculators

  • “All scientific calculators are allowed.” This is false. While many are, specific features like graphing, programming, or CAS are strictly forbidden.
  • “If it’s not explicitly banned, it’s allowed.” The NCEES policy outlines what *is* allowed and what features are prohibited. Relying on the absence of a ban is risky; it’s best to check against the prohibited features.
  • “My calculator was allowed on my university’s engineering exam, so it’s allowed on the FE.” University policies can differ significantly from NCEES standards. Always defer to the official NCEES rules for the actual exam.

FE Exam Calculator Rules: Formula and Mathematical Explanation

The NCEES calculator policy isn’t a complex mathematical formula, but rather a set of clear, binary criteria (Yes/No) applied to specific calculator features. To determine compliance, we evaluate each feature against the NCEES prohibitions. If any prohibited feature is present, the calculator is non-compliant. If none of the prohibited features are present, and it’s not a prohibited model, it is generally considered compliant.

Compliance Logic:

A calculator is compliant IF AND ONLY IF:

  1. It is NOT a graphing calculator.
  2. It is NOT programmable.
  3. It does NOT have a QWERTY keyboard.
  4. It does NOT have a Computer Algebra System (CAS).
  5. It does NOT have wireless or other communication features.
  6. It is NOT on the NCEES explicitly banned list (though this is rare if the above criteria are met).

The core calculation logic in our checker reflects this:


var isCompliant = true;
var reasons = [];

if (isGraphing === 'yes') {
isCompliant = false;
reasons.push("is a graphing calculator");
}
if (isProgrammable === 'yes') {
isCompliant = false;
reasons.push("is programmable");
}
if (hasQWERTY === 'yes') {
isCompliant = false;
reasons.push("has a QWERTY keyboard");
}
if (hasCAS === 'yes') {
isCompliant = false;
reasons.push("has Computer Algebra System (CAS)");
}
if (hasCommunication === 'yes') {
isCompliant = false;
reasons.push("has communication features");
}

var finalStatus = isCompliant ? "Likely Compliant" : "Non-Compliant";
var complianceReasoning = "";

if (isCompliant) {
complianceReasoning = "Based on your inputs, the calculator meets NCEES criteria for non-prohibited features.";
} else {
complianceReasoning = "The calculator is non-compliant because it " + reasons.join(', ') + ".";
}

Variables Table:

Calculator Feature Variables
Variable Meaning Unit Typical Range
isGraphing Indicates if the calculator can plot functions. Yes/No Yes, No
isProgrammable Indicates if the calculator allows users to write and store custom programs. Yes/No Yes, No
hasQWERTY Indicates if the calculator has a full standard keyboard layout. Yes/No Yes, No
hasCAS Indicates if the calculator has a system that can perform symbolic mathematics (e.g., simplifying algebraic expressions automatically). Yes/No Yes, No
hasCommunication Indicates if the calculator has features for wireless data transfer (e.g., Bluetooth, Wi-Fi) or other communication interfaces. Yes/No Yes, No

Practical Examples of FE Exam Calculator Compliance

Key Factors That Affect FE Exam Calculator Compliance

Several key characteristics of a calculator determine whether it meets the NCEES standards for the FE exam. Understanding these factors is crucial for making an informed decision.

  1. Graphing Capability: This is perhaps the most significant disqualifier. Calculators that can plot mathematical functions (e.g., y = f(x)) are strictly prohibited. The FE exam tests your fundamental understanding and application of engineering principles, not your ability to interpret complex graphs generated by a device.
  2. Programmability: Calculators that allow users to write, store, and execute custom programs are not permitted. This includes programs for solving specific engineering equations or performing complex iterative calculations beyond standard functions. The exam aims to test your ability to apply formulas and algorithms manually, not to run pre-written code.
  3. QWERTY Keyboard: Calculators featuring a full standard alphanumeric keyboard (like a computer keyboard) are banned. This feature often overlaps with programmability and data storage, making them too advanced for the exam’s scope.
  4. Computer Algebra System (CAS): Calculators with CAS functionality can perform symbolic mathematics, such as simplifying algebraic expressions, finding derivatives or integrals symbolically, and solving equations algebraically. This level of advanced mathematical processing is not allowed. The focus is on numerical computation and applying engineering principles.
  5. Wireless or Communication Features: Any calculator with the ability to transmit or receive data wirelessly (e.g., Bluetooth, Wi-Fi, infrared) or connect to other devices is strictly forbidden. This is a security measure to prevent unauthorized communication or data access during the exam.
  6. Memory and Data Storage: While not always explicitly listed as a separate point, calculators with extensive memory for storing notes, formulas, or large datasets are generally not allowed. Approved calculators typically have limited memory, sufficient only for calculations and basic function storage. The exam relies on your knowledge, not stored data.
  7. Power Source (Implicit): While not a feature, NCEES requires calculators to be battery-powered. Calculators requiring external power sources are not suitable. NCEES also recommends that candidates bring spare batteries.
  8. NCEES Explicitly Banned List: NCEES maintains a list of specific models that are banned. While most bans stem from the features listed above, it’s always prudent to check this list. However, if your calculator lacks all prohibited features, it’s unlikely to be on this list.

FE Exam Calculator FAQ

What is the main goal of the NCEES calculator policy?

The primary goal is to ensure a fair and standardized testing environment for all candidates by preventing the use of devices that provide an unfair computational or informational advantage. The policy focuses on basic, non-programmable, non-graphing scientific calculators.

Can I use a calculator that has some, but not all, prohibited features?

No. If your calculator possesses even one prohibited feature (like being a graphing calculator or programmable), it is considered non-compliant and cannot be used on the FE exam.

Where can I find the official list of approved calculators?

You can find the official list on the NCEES website. Search for “NCEES Approved Calculator List” or follow the link provided in our calculator’s results section. It’s crucial to consult this list for the most up-to-date information.

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

If you bring a non-approved calculator, you will likely be dismissed from the examination center and your exam results may be invalidated. You could also face further disciplinary action from NCEES. It’s essential to ensure compliance beforehand.

Are financial calculators allowed on the FE exam?

Generally, specialized financial calculators are not recommended unless they meet the specific criteria for approved scientific calculators (non-graphing, non-programmable, etc.) and are explicitly listed or fall within the NCEES guidelines. Most advanced financial calculators have features that would make them non-compliant. Stick to standard scientific models.

My calculator has a “solver” function. Is that considered programmable or CAS?

It depends on the implementation. If the “solver” function is a built-in feature for solving standard equations numerically (like quadratic formula solvers), it might be acceptable. However, if it can solve complex symbolic equations or requires user programming to set up, it could be deemed non-compliant. When in doubt, check the NCEES list or choose a calculator without such advanced solver functions.

What should I do if my calculator model isn’t on the NCEES list?

If your specific model is not listed, carefully evaluate its features against the NCEES prohibited features (graphing, programming, QWERTY, CAS, communication). If it has none of these, it *may* still be allowed, but NCEES recommends using a calculator from their approved list to be absolutely certain. It’s safer to choose a calculator that is explicitly approved.

Can I bring multiple calculators to the FE exam?

Yes, you can bring multiple calculators, provided they are all compliant with the NCEES policy. This is a good practice in case your primary calculator malfunctions or runs out of battery. Ensure each calculator you bring meets all the requirements.

What about calculators for specific disciplines, like civil or electrical engineering?

The NCEES calculator policy applies universally across all FE disciplines. There are no discipline-specific approved calculators. The rules regarding graphing, programmability, CAS, QWERTY keyboards, and communication features are the same for everyone, regardless of the engineering field they are testing in.
