This table summarizes the official College Board policy for calculator use on the PSAT 8/9. Always check the latest rules before your test.

What is the PSAT 8/9 Calculator Use Policy?

The PSAT 8/9 calculator use policy is a set of rules established by the College Board to ensure fairness and a standardized testing environment for all students. The policy dictates which types of calculators are allowed, which are prohibited, and during which sections of the test a calculator may be used. Understanding the PSAT 8/9 calculator use rules is crucial for test day success, as using a non-approved device can lead to dismissal. There are two math sections: one where no calculators are allowed, and one where an approved calculator is permitted and recommended.

This policy is for all 8th and 9th graders taking the PSAT 8/9. A common misconception is that any graphing calculator is acceptable. However, the key distinction is whether the calculator has a Computer Algebra System (CAS), which is strictly forbidden. The purpose of the PSAT 8/9 calculator use rules is to test mathematical reasoning, not just the ability to operate a powerful machine.

PSAT 8/9 Calculator Use “Formula” and Explanation

The “formula” for determining if a calculator is allowed is a straightforward decision-making process rather than a mathematical equation. It follows a simple, two-step logic:

1. Check the Test Section: Is it the “Math Test – No Calculator” or the “Math Test – Calculator” section? If it’s the ‘No Calculator’ section, the process ends—no calculators are allowed.
2. Check the Device Type: If it’s the ‘Calculator’ section, identify your device. It must not be on the prohibited list. Prohibited devices include those with internet access, QWERTY keyboards, or Computer Algebra Systems (CAS). Generally, most graphing, scientific, and four-function calculators are fine.

The core of the PSAT 8/9 calculator use policy is identifying and excluding devices that can provide an unfair advantage, such as those that can solve algebraic equations symbolically.

Variables in the Decision Process

Variable	Meaning	Possible Values	Typical Range
Test Section	The specific part of the PSAT 8/9 math test.	Calculator, No-Calculator	N/A
Device Type	The category of your calculating device.	Graphing, Scientific, CAS, Phone, etc.	TI-84 (Graphing), TI-30X (Scientific)
CAS Feature	Computer Algebra System functionality.	Yes, No	“CAS” in model name indicates Yes.
Connectivity	Features like Wi-Fi, Bluetooth, or cellular data.	Yes, No	Any connectivity is prohibited.

Practical Examples of PSAT 8/9 Calculator Use

Example 1: Student with a TI-84 Plus

• Inputs: Test Section = “Math Test – Calculator”, Calculator Type = “Graphing Calculator (e.g., TI-84)”
• Output: PERMITTED
• Interpretation: The TI-84 Plus is a standard graphing calculator without CAS functionality. It is one of the most common and widely accepted calculators for the PSAT 8/9 calculator use policy. The student can confidently use it during the designated section. For more details, you can explore a guide on approved calculators.

Example 2: Student with a TI-Nspire CX II-T CAS

• Inputs: Test Section = “Math Test – Calculator”, Calculator Type = “Advanced/CAS Calculator”
• Output: PROHIBITED
• Interpretation: Despite being a graphing calculator, this model has “CAS” in its name, which stands for Computer Algebra System. The PSAT 8/9 calculator use policy explicitly forbids devices with CAS. The student must bring a different, non-CAS calculator.

How to Use This PSAT 8/9 Calculator Use Calculator

This tool simplifies the official College Board rules into two easy steps:

1. Select the Test Section: Choose whether you are in the “Math Test – Calculator” or “Math Test – No Calculator” portion of the exam. The rules change completely between these two sections.
2. Select Your Calculator Type: From the second dropdown, choose the category that best fits your calculator. We’ve included common types from basic four-function models to prohibited devices like phones.
3. Read the Result: The tool will instantly provide a clear “PERMITTED” or “PROHIBITED” status. The detailed explanation below the main result tells you why that decision was made, helping you understand the specific PSAT 8/9 calculator use rule that applies. This can help you decide if you need to find an alternative calculator before test day. A PSAT Math overview can provide further context.

Key Factors That Affect PSAT 8/9 Calculator Use

1. Computer Algebra System (CAS): This is the most critical factor. If your calculator can symbolically manipulate algebraic expressions (e.g., factor `x^2-1` into `(x-1)(x+1)`), it has CAS and is prohibited.
2. QWERTY Keyboard: Any device with a typewriter-style keyboard is not allowed.
3. Connectivity: Calculators or devices with Wi-Fi, Bluetooth, cellular, or any wireless communication capability are strictly forbidden.
4. Power Source: Calculators must be battery-operated. Models that require an electrical outlet are not permitted.
5. Noise and Printing: Any calculator that makes noise or has a paper tape printer is not allowed.
6. Test Section: The most basic factor is the section you’re in. The “Math Test – No Calculator” section, which lasts 20 minutes, bans all calculators. It’s essential to follow this rule to the letter. Consider reviewing our PSAT test day checklist.

Frequently Asked Questions (FAQ)

1. Do I need a calculator for the PSAT 8/9?

While no question requires a calculator to be solved, it is highly recommended for the “Math Test – Calculator” section. It can save significant time on arithmetic and complex calculations. Exploring a PSAT vs SAT comparison might also be useful.

2. Can I use the calculator built into the testing app?

Yes, the digital PSAT 8/9 administered on the Bluebook™ app has a built-in Desmos calculator that you can use. You are allowed to bring your own approved handheld calculator as well.

3. What if my calculator’s battery dies during the test?

You are responsible for ensuring your calculator is in working order. It’s a good idea to install fresh batteries before test day or bring a backup calculator and extra batteries (you must ask for permission to access them).

4. Are all scientific calculators allowed?

Nearly all scientific calculators are allowed, as long as they do not have any of the prohibited features like CAS or a QWERTY keyboard. The PSAT 8/9 calculator use policy is flexible here.

5. Is a TI-83 Plus allowed?

Yes, the TI-83 Plus is a very common and perfectly acceptable graphing calculator for the PSAT 8/9. It does not have CAS functionality.

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

Policies may require you to clear programs and stored documents from your calculator. It’s best practice to do so before the test to avoid any issues.

7. Can I share my calculator with another student?

No. Sharing calculators is not permitted during the exam. Each student must have their own approved device.

8. Where can I find the official, most up-to-date PSAT 8/9 calculator use policy?

The definitive source for the PSAT 8/9 calculator use policy is the College Board’s official website. Always check their site for the latest rules before your test date. You may find our page of official College Board links helpful.
