What is the EIT Exam Calculator Policy in California?
When preparing for the Fundamentals of Engineering (FE) exam, often called the Engineer-in-Training (EIT) exam, in California, one of the most critical rules to understand is the calculator policy. The policy isn’t set by the state of California but by the National Council of Examiners for Engineering and Surveying (NCEES), which administers the exam nationwide.
The short answer is: **Yes, you can use your own calculator, but ONLY if it is one of the models explicitly approved by NCEES.** This policy is strictly enforced to ensure fairness and prevent any possibility of cheating by using devices with communication or extensive data storage capabilities. Bringing a non-approved calculator will result in you not being able to use it, and potentially having your exam invalidated.
NCEES Approved Calculator Models List
The NCEES reviews its calculator policy annually, but the list of approved manufacturers and model series has been stable for many years. The only calculators permitted for use in 2026 exams fall under three brands.
| Manufacturer | Approved Models / Series | Key Rule |
|---|---|---|
| Texas Instruments | All TI-30X and TI-36X models | The model name MUST contain “TI-30X” or “TI-36X”. Examples include the TI-30X IIS and the popular TI-36X Pro. |
| Casio | All fx-115 and fx-991 models | The model name MUST contain “fx-115” or “fx-991”. Examples include the fx-115ES Plus. |
| Hewlett Packard | HP 33s and HP 35s | Only these two specific models are allowed. No other HP models are permitted. |
How to Use This EIT Exam Calculator Checker
Our tool is designed to simplify the process of verifying your calculator.
- Find Your Model Name: Look at the face or back of your calculator to find the exact model name (e.g., “fx-115ES PLUS”, “TI-36X Pro”).
- Enter the Model Name: Type the full name into the input field above.
- Check the Status: Click the “Check Approval Status” button.
- Review the Result: The tool will instantly tell you if your calculator is on the approved list based on NCEES guidelines.
Practical Example
If you enter **”TI-89″**, a powerful graphing calculator, the tool will return a “Not Approved” status. This is because graphing calculators are banned due to their advanced capabilities. If you enter **”Casio fx-115″**, the tool will return “Approved” because it fits the NCEES rule.
Key Factors and Rules for the EIT Exam
- No Sharing: You cannot share your calculator with another examinee during the test.
- Battery Life: Ensure your calculator has fresh batteries or is fully charged. While some models are solar-powered, it’s a good idea to have a reliable power source. Consider bringing an approved backup calculator.
- No Advanced Features: The policy prohibits calculators with features like wireless communication, internet access, or the ability to store large amounts of text or programs.
- On-Screen Calculator: The computer-based exam includes an on-screen digital calculator (a version of the TI-30X IIS). While this is a useful backup, it is generally slower to use than a physical, handheld calculator you are familiar with.
- Familiarity is Key: You should purchase your approved calculator well in advance and use it for all your studying. Being deeply familiar with its functions is a significant advantage on exam day.
- Physical Inspection: Proctors will inspect your calculator upon entry to the testing room. They have the final say on whether a device is permitted.
Frequently Asked Questions (FAQ)
What if my calculator model is very similar to an approved one?
It must match the NCEES naming rule exactly. For example, a “TI-30” is not a “TI-30X” and would not be allowed. The model name must *contain* the approved series designation.
Can I bring two calculators into the exam?
You may bring more than one *approved* calculator to the exam center, but you can only have one at your desk. The spare must be stored with your personal belongings.
Are graphing calculators like the TI-89 or TI-Nspire allowed?
No. All graphing calculators are strictly forbidden because of their advanced computing and storage capabilities.
Do I need to clear my calculator’s memory?
The approved models do not have the extensive memory or programming features that are of concern. A simple memory clear is good practice, but not a formal requirement for these specific models.
Does the policy change often?
NCEES reviews the policy annually, but the core list of approved models has been very consistent for many years. It is always best to check the official NCEES website for the most current policy before your exam.
What is the difference between the EIT and FE exam?
There is no difference. The Fundamentals of Engineering (FE) exam is the modern name for what was traditionally called the Engineer-in-Training (EIT) exam.
Where can I find the official policy?
The definitive source for the calculator policy is the NCEES website, under the “Exams” section.
What happens if I’m caught with a non-approved calculator?
Your exam could be invalidated, and you may face other disciplinary actions from NCEES. It is not worth the risk.
