PSAT Calculator Approval Checker

Is Your Calculator Allowed on the PSAT?

Enter your calculator’s model number to see if it meets the College Board’s policy for the PSAT/NMSQT.

Understanding the PSAT Calculator Policy

One of the most common questions students have when preparing for the PSAT/NMSQT is: what calculator can I use on the PSAT? The answer is crucial, as using a prohibited device can lead to score cancellation. The College Board has a specific policy that divides calculators into three categories: approved, prohibited, and those that require inspection. This guide will help you understand the rules and use our checker to verify your device.

The PSAT has two math sections: one where no calculator is allowed, and one where an approved calculator is permitted. It is vital to bring a calculator you are familiar with to the test.

Approved vs. Prohibited Calculator Features

Instead of a mathematical formula, the PSAT policy is a set of rules. Generally, most graphing calculators, all scientific calculators, and all four-function calculators are permitted. However, devices with features that give an unfair advantage are strictly banned. The digital PSAT also includes an embedded Desmos calculator, which has both graphing and scientific modes.

Summary of PSAT Calculator Compliance Rules

Feature / Type	Status	Explanation & Examples
Scientific Calculators	Permitted	All scientific calculators are allowed. (e.g., TI-30X, Casio FX-991EX).
Graphing Calculators (Non-CAS)	Permitted	Most are allowed. (e.g., TI-84 Plus, TI-Nspire CX (non-CAS)).
Computer Algebra System (CAS)	Prohibited	Calculators that can symbolically solve equations are banned. (e.g., TI-89, TI-Nspire CAS, HP Prime).
QWERTY Keyboard	Prohibited	Any device with a typewriter-style keyboard is not allowed.
Internet/Bluetooth Access	Prohibited	Calculators that can communicate wirelessly are banned.
Phones, Tablets, Laptops	Prohibited	No general-purpose computing devices are allowed.
Needs an Electrical Outlet	Prohibited	Calculators must be battery-operated.

Practical Examples

Understanding the rules is easier with examples.

• Example 1: The Compliant Student
  
  A student enters “TI-84 Plus CE” into the checker. The calculator is a standard graphing calculator without CAS. The tool shows: Approved. The student can confidently bring this to the test.
• Example 2: The Prohibited Calculator
  
  Another student enters “TI-Nspire CX II CAS”. The “CAS” (Computer Algebra System) is the key issue. The tool shows: Prohibited. This calculator is not allowed because it can perform symbolic algebra, which is against College Board rules.

How to Use This PSAT Calculator Checker

Using our tool is simple and gives you instant peace of mind.

1. Locate the Model Number: Find the model number printed on the front of your calculator (e.g., on the top case or above the screen).
2. Enter the Model: Type the full model number into the input field above.
3. Check Status: Click the “Check Status” button.
4. Review the Result: The tool will tell you if your calculator is generally approved or prohibited based on known PSAT rules. Always double-check with the official College Board PSAT calculator policy for the most current list.

Key Factors That Affect Calculator Choice

Choosing the right, approved calculator is important. Here are some factors to consider:

• Familiarity: The best calculator is the one you already know how to use. Don’t switch to a new, complex model right before the test.
• Functionality: A graphing calculator can be very helpful for visualizing functions, but a good scientific calculator is sufficient for all PSAT math questions.
• Battery Life: Ensure your calculator has fresh batteries. It’s a good idea to bring a backup calculator or spare batteries if allowed.
• No CAS: This is the most critical factor. Make sure your graphing calculator does not have a “CAS” or Computer Algebra System. If you are unsure, our PSAT calculator approval tool can help.
• Practice: Practice with the same calculator you will use on test day. This includes practicing with the built-in Desmos calculator if that is your plan.
• Physical Condition: Make sure your calculator doesn’t have a raised display that is visible to others, or it may require special seating.

Frequently Asked Questions (FAQ)

1. Can I use my phone’s calculator on the PSAT?

No. Phones, smartwatches, laptops, and tablets are strictly prohibited.

2. What happens if I bring a banned calculator?

You will not be allowed to use it. In some cases, your scores could be canceled, and you may be dismissed from the test.

3. Is a scientific calculator good enough for the PSAT?

Yes. All questions can be solved with a scientific calculator, and many can be solved without one at all. A scientific calculator is a safe and sufficient choice.

4. 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 “CX” model is permitted. Pay close attention to the model name.

5. Are all TI-84 calculators allowed?

Yes, all models in the TI-84 family (Plus, CE, Silver Edition) are approved for the PSAT. They are a popular and reliable choice.

6. Do I have to clear my calculator’s memory?

It is highly recommended. Test proctors may inspect your calculator, and clearing the memory ensures no prohibited programs or notes are stored.

7. Can I share a calculator with another student?

No. Each student must have their own calculator. Sharing is not permitted.

8. Where can I find the official list of approved calculators?

The most up-to-date policy is always on the College Board’s official website. You can find more details on their PSAT Calculator Policy page.
