Approved Calculators For Fe Exam

The NCEES has a strict policy on which calculators are permitted during the Fundamentals of Engineering (FE) exam. Using a non-approved model can result in disqualification. Use this tool to quickly verify if your calculator is on the approved list.

Calculator Approval Checker

Logic Used: This checker verifies your input against the NCEES calculator policy. It checks if the model name contains an approved series identifier (like “fx-115” or “TI-36X”) or matches a specific approved model (like “HP 35s”).

What Are Approved Calculators for the FE Exam?

The term “approved calculators for fe exam” refers to a specific, limited list of calculator models that the National Council of Examiners for Engineering and Surveying (NCEES) permits for use during the Fundamentals of Engineering (FE) and Principles and Practice of Engineering (PE) exams. This policy is not about suggesting the “best” calculators, but about standardizing the tools available to ensure fairness and exam integrity. The core principle is to prevent the use of devices with capabilities that could provide an unfair advantage, such as extensive text storage, wireless communication, or graphical plotting features.

This policy is critical for every exam candidate. Arriving on exam day with a non-approved calculator will result in it being confiscated, forcing you to rely on the limited on-screen calculator, which can significantly slow you down. The list of approved calculators for fe exam is reviewed annually, so it’s essential to check the latest policy before your exam date. Common misconceptions include thinking any “scientific” calculator is fine or that more expensive, powerful calculators are allowed. In reality, the NCEES policy strictly limits models to specific lines from Casio, Texas Instruments, and Hewlett Packard.

The NCEES Calculator Approval Logic Explained

There isn’t a mathematical formula for approval, but rather a logical one based on a set of rules defined by the NCEES. This logic ensures that all approved calculators for fe exam share a similar, non-programmable, non-communicating feature set. Here’s a step-by-step breakdown of the approval “logic”:

1. Rule 1: Manufacturer Check. The calculator must be manufactured by Casio, Texas Instruments (TI), or Hewlett-Packard (HP).
2. Rule 2: Model Series/Name Check. This is the most critical step. The device’s model name must conform to one of the following patterns:
   • 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 must be *exactly* an “HP 33s” or “HP 35s”. No other HP models are permitted.
3. Rule 3: Feature Prohibition Check. The policy implicitly prohibits features like QWERTY keyboards, wireless communication (Bluetooth, IR), paper tape, or the ability to connect to other devices. The approved models inherently lack these features.

NCEES Approval Rules Summary

Manufacturer	Approval Rule	Example Approved Model	Example Unapproved Model
Casio	Model name includes “fx-115” or “fx-991”	fx-115ES Plus	Casio fx-9750GII (graphing)
Texas Instruments	Model name includes “TI-30X” or “TI-36X”	TI-36X Pro	TI-89 Titanium (CAS)
Hewlett-Packard	Model is exactly “HP 33s” or “HP 35s”	HP 35s	HP Prime (graphing, touchscreen)

Practical Examples (Real-World Use Cases)

Understanding the application of the policy is key. Here are two realistic scenarios that engineering candidates face regarding the approved calculators for fe exam.

Example 1: The Over-Prepared Student with the Wrong Tool

Alex, a mechanical engineering student, has used a powerful TI-Nspire CX CAS calculator throughout college. It’s a fantastic tool that can solve complex symbolic equations. Assuming it’s the best tool for the job, Alex brings it to the FE exam. At check-in, the proctor inspects the calculator and informs Alex that it is not on the approved list because of its computer algebra system (CAS) and graphing capabilities. Alex is forced to leave it behind and use the on-screen digital calculator, losing valuable time and comfort during the exam.

Example 2: The Compliant Student with the Right Tool

Maria is preparing for the FE Civil exam. Early in her studies, she consults the NCEES website and learns about the list of approved calculators for fe exam. She purchases a TI-36X Pro, one of the most popular approved calculators. For six months, she uses only this calculator for all her practice problems. On exam day, the proctor quickly approves her calculator. Maria is efficient and confident, as she has muscle memory for all the key functions, saving precious seconds on every calculation-based question. This familiarity contributes significantly to her finishing the exam on time. For more on exam strategy, see our FE Exam Prep Guide.

5. Copy Your Result: The “Copy Results” button will copy a summary of the outcome to your clipboard, perfect for saving or sharing.

Key Factors of the NCEES Calculator Policy

Several factors influence the list of approved calculators for fe exam. Understanding them can prevent surprises.

• Exam Integrity: The primary goal is to prevent cheating. Prohibited features include anything that can store extensive text, solve symbolic equations, or communicate with other devices.
• Standardization: By limiting the tools, NCEES ensures that no candidate has an unfair advantage over others due to superior calculator technology.
• Annual Review: NCEES reviews the policy annually. While the core list has been stable for years, it’s always best to check the official NCEES site for the policy governing your exam year. Minor changes could occur.
• Model Name Specificity: The rule is strict. If the model name doesn’t contain the exact required string (e.g., “fx-115”), it’s not allowed. A Casio “fx-95” is not approved, even though it’s less powerful.
• No Exceptions: Exam proctors have no discretion. They cannot make exceptions for a calculator that is “almost” the same as an approved one. The policy is absolute. Becoming an expert with your chosen device is part of your preparation. Consider reviewing resources on PE exam resources for advanced tips.
• Battery and Backup Policy: While not part of the model approval, remember to bring a calculator with fresh batteries. Some testing centers may have restrictions on bringing a backup calculator, so check your specific center’s rules.

Frequently Asked Questions (FAQ)

• 1. Why are graphing calculators not allowed?
  Graphing calculators, like the TI-84 or TI-Nspire, are banned because their screens can display extensive graphs and text, and many can store formulas or notes, which violates the principle of standardized testing. The list of approved calculators for fe exam is designed to prevent this.
• 2. What happens if my calculator runs out of batteries during the exam?
  You will be forced to use the on-screen digital calculator provided in the exam software. This is why it is critical to install fresh batteries right before exam day.
• 3. Can I bring two approved calculators?
  This depends on the specific testing center’s policy, but NCEES generally allows it. However, you should confirm with your Pearson VUE testing center beforehand.
• 4. Is the on-screen calculator a good backup?
  The on-screen calculator is a functional replica of a TI-30X IIS. It works, but it’s much slower to use with a mouse than a physical calculator. It should be considered an emergency option only.
• 5. I have an older model, the Casio fx-115MS. Is it still approved?
  Yes. As long as the model name contains “fx-115”, it is approved. The policy covers all versions of the series, new and old.
• 6. Is the TI-36X Pro the best approved calculator for the FE exam?
  Many consider it the best due to its powerful solver, matrix, and vector capabilities. However, the “best” calculator is the one you are most familiar with. Any approved model is sufficient to pass. A professional engineer needs the right tools for their work, including the right engineering laptop.
• 7. Do I need to clear my calculator’s memory before the exam?
  Exam proctors are trained to clear the memory of the few models that have programmable functions (like the HP 35s). It’s a standard procedure during check-in.
• 8. Where can I find the official, most up-to-date policy?
  The definitive source is always the NCEES official website (ncees.org). Always check there before making a purchase or heading to your exam. Proper registration is also vital; learn more about the registration steps here.
