Answer the questions below to determine if your calculator is permitted on the NYS Physics Regents exam.

What is the Official Policy on Graphing Calculators for the Physics Regents?

The New York State Education Department (NYSED) sets the rules for what tools students can use during Regents Examinations. For the Physics Regents, the policy is designed to ensure a fair testing environment, preventing access to stored information or unfair computational advantages. While scientific and graphing calculators are permitted, they must not have features that could compromise test integrity.

Essentially, any calculator that can communicate with other devices or perform symbolic algebra is forbidden. Standard graphing calculators that perform numerical calculations and graphing are generally allowed, provided their memory is cleared before the exam.

Physics Regents Calculator “Formula” and Explanation

You can think of the eligibility rules as a logical formula. A calculator is **Allowed** if and only if all the following conditions are true:

Eligibility = (NOT hasInternet) AND (NOT hasCAS) AND (NOT hasQwerty) AND (NOT hasStylus)

Here’s a breakdown of what those terms mean in the context of the exam:

Eligibility Variable Definitions

Variable	Meaning	Unit/Type	Typical Range
hasInternet	The calculator can connect to Wi-Fi, Bluetooth, or any other network.	Boolean (True/False)	Must be False.
hasCAS	The calculator has a Computer Algebra System, which can solve symbolic equations.	Boolean (True/False)	Must be False.
hasQwerty	The calculator has a typewriter-style (QWERTY) keyboard.	Boolean (True/False)	Must be False.
hasStylus	The calculator uses a stylus, pen, or touch-screen for input.	Boolean (True/False)	Must be False.

Practical Examples

Example 1: A Permitted Calculator

A student has a TI-84 Plus. Using the calculator above:

• Inputs: Type = Graphing, CAS = No, Internet = No, QWERTY = No, Stylus = No.
• Result: ALLOWED (with memory cleared).
• Reasoning: The TI-84 Plus is a standard graphing calculator without any prohibited features. Its memory must be cleared before the exam.

Example 2: A Prohibited Calculator

A student has a TI-Nspire CX II CAS. Using the calculator:

• Inputs: Type = Graphing, CAS = Yes.
• Result: NOT ALLOWED.
• Reasoning: The “CAS” in the model name stands for Computer Algebra System, which is explicitly forbidden on Regents exams.

How to Use This Physics Regents Calculator Eligibility Checker

This tool simplifies the official rules into a few easy steps:

1. Select Your Calculator Type: Choose whether you have a graphing, scientific, or basic four-function calculator. Most calculators used for physics will be scientific or graphing.
2. Check for Prohibited Features: Carefully review the list of features. If your calculator has *any* of them, check the corresponding box. Be honest—it’s better to know now than on test day. The most common prohibited feature is a Computer Algebra System (CAS).
3. Review the Result: The tool will immediately provide a clear “ALLOWED” or “NOT ALLOWED” verdict based on your inputs. It will also explain the reasoning.
4. Take Action: If your calculator is allowed, make sure you know {related_keywords}. If it’s not allowed, you’ll need to find an approved alternative for the exam.

Key Factors That Affect Calculator Eligibility

• Computer Algebra System (CAS): This is the most common reason a powerful calculator is banned. CAS can perform algebraic manipulations (like solving for x), which is considered an unfair advantage.
• Communication Capabilities: Any calculator that can connect to the internet, Wi-Fi, or Bluetooth is strictly forbidden. This includes smartwatches and phones.
• QWERTY Keyboard: Calculators with a full keyboard are prohibited as they make it easier to store text.
• Stylus or Touch Screen: Devices that require a stylus or are primarily touch-screen operated are generally not allowed.
• Stored Programs and Data: For approved graphing calculators, all user-stored programs, notes, and data must be cleared before the exam begins.
• Noise: Calculators that make noise must be silenced.

Prohibited vs. Allowed Calculators

The following table provides examples of common calculator models and their status for the Physics Regents exam. This is not an exhaustive list.

Common Calculator Models and Their Regents Status

Model	Type	Status	Reasoning
TI-84 Plus / CE	Graphing	Allowed	Standard graphing calculator. Memory must be cleared.
TI-83 Plus	Graphing	Allowed	Older standard model. Memory must be cleared.
TI-Nspire CX II (non-CAS)	Graphing	Allowed	The non-CAS version is permitted. Memory must be cleared.
TI-Nspire CX II CAS	Graphing (CAS)	Not Allowed	Contains a Computer Algebra System (CAS).
TI-89 Titanium	Graphing (CAS)	Not Allowed	Contains a Computer Algebra System (CAS).
Casio fx-9750GII	Graphing	Allowed	Standard graphing calculator without CAS.
Any Smartphone App	N/A	Not Allowed	Has communication capabilities and other banned features.

Frequently Asked Questions (FAQ)

1. Do I have to use a graphing calculator on the Physics Regents?

No, it is not required. A standard scientific calculator is sufficient for all calculations on the exam. However, a graphing calculator is permitted if it meets the criteria.

2. How do I clear the memory on my TI-84 Plus?

Turn on the calculator. Press [2nd], then [+] to access the MEMORY menu. Select 7: Reset… Choose 1: All RAM, then 2: Reset. Your proctor may also perform this for you.

3. What’s the difference between a TI-Nspire CX and a TI-Nspire CX CAS?

The “CAS” model includes a Computer Algebra System, which is banned. The non-CAS model is allowed. Be sure to check the exact model name on the calculator’s face.

4. Can I use a calculator app on my tablet or phone?

No. All devices with communication capabilities, like phones and tablets, are strictly forbidden during the exam.

5. What if I’m not sure if my calculator has CAS?

A simple test: try to solve an equation like `2x – 10 = 0`. If the calculator returns `x = 5`, it likely has CAS. A non-CAS calculator would give a syntax error. Consult your teacher or the official {related_keywords} list if you are unsure.

6. Are programs allowed on the calculator?

No. Clearing the RAM, which is a requirement, will delete all user-added programs and data. You cannot use pre-loaded programs to solve questions.

7. Is the Desmos calculator allowed?

The Desmos calculator is often integrated into the digital version of Regents exams, but you cannot use the public web version on a personal device. If your school provides a device with a locked-down version of Desmos, that is permitted.

8. Are scientific calculators always safe?

Almost always, yes. Standard scientific calculators (like the TI-30 series) do not have the advanced features that are prohibited. They are a safe and reliable choice for the Physics Regents.
