What is the SAT Calculator Policy?

The question, “can you use a calculator on the SATs,” is a critical one for test-day success. The College Board has a very specific policy to ensure fairness. The SAT Math test is divided into two parts: a ‘Math Test – No-Calculator’ section and a ‘Math Test – Calculator’ section. As the names imply, you are only permitted to use a device on the latter. Calculators are strictly forbidden during the Reading, Writing, and Language sections.

The primary goal is to assess a range of mathematical skills. The No-Calculator section tests your mental math, problem-solving fluency, and conceptual understanding, while the Calculator section allows you to tackle more complex computations efficiently. However, it’s important to note that a calculator is not strictly necessary for any question, even in the permitted section.

SAT Calculator Rules and Prohibited Features

Understanding which features are forbidden is the key to determining if your device is compliant. The College Board prohibits any calculator that can provide an unfair advantage or pose a security risk. A major recent change is the prohibition of calculators with a built-in Computer Algebra System (CAS).

This table outlines explicitly prohibited calculator features.

Prohibited Feature	Reasoning for Prohibition	Typical Unit/Format
Computer Algebra System (CAS)	Can perform symbolic algebra (e.g., solve for x). This is a major policy violation.	Functionality (e.g., ‘solve()’)
Wireless Communication	Bluetooth, Wi-Fi, or any internet capability is a major security risk.	Connectivity (e.g., 802.11ac)
QWERTY Keyboard	Resembles a computer, which is not allowed.	Layout (Keyboard)
Electrical Outlet Requirement	Calculators must be battery-operated.	Power Source (AC Power)
Stylus or Touch Pen	Models requiring a stylus (like some Casio ClassPad models) are banned.	Input Method (Pen/Stylus)
Makes Noise or Prints	Devices cannot make noise or have a paper tape printer.	Output (Audio/Paper)

Practical Examples

Example 1: A Student with a TI-84 Plus

A student brings a Texas Instruments TI-84 Plus, a standard graphing calculator, to use on the Math Test – Calculator section. It does not have a QWERTY keyboard, CAS, or wireless features.

• Inputs: Section = Math Test – Calculator, Prohibited Features = None
• Result: ALLOWED. This is a standard and widely approved graphing calculator.

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

Another student brings a TI-Nspire CX II CAS. Although it’s a powerful calculator, its “CAS” designation is a problem.

• Inputs: Section = Math Test – Calculator, Prohibited Features = Computer Algebra System (CAS)
• Result: NOT ALLOWED. The College Board explicitly prohibits calculators with CAS functionality.

How to Use This SAT Calculator Policy Checker

Using this tool is a straightforward way to see if you can use a calculator on the SATs. Follow these simple steps:

1. Select the SAT Section: Choose the part of the test you are preparing for from the first dropdown menu. Remember, calculators are only for the designated math section.
2. Identify Prohibited Features: Carefully review the checklist. If your calculator has any of the listed features (like a QWERTY keyboard or CAS), check the corresponding box.
3. Review Your Result: The tool will instantly provide a clear “ALLOWED” or “NOT ALLOWED” status. The explanation tells you exactly why that decision was reached, based on official SAT policy.
4. Reset for a New Check: Click the “Reset” button to clear the form and check another calculator or scenario.

Key Factors That Affect Your Calculator Choice

Choosing the right calculator—and knowing how to use it—is a strategic decision.

• Familiarity: The best calculator is one you are comfortable with. Don’t buy a new, complex model right before the test. Practice is key.
• Battery Power: Ensure your calculator has fresh batteries. Since devices needing an outlet are banned, a dead battery means no calculator.
• Approved Models: While most scientific and graphing calculators are fine, it’s wise to check your model against the official College Board list if you’re unsure. The {related_keywords} list includes many common models from Texas Instruments, Casio, and HP.
• No CAS Functionality: This is a critical rule. Models like the TI-Nspire CAS are explicitly forbidden, while the non-CAS TI-Nspire is allowed. Double-check your model number.
• Graphing vs. Scientific: A graphing calculator can be powerful for visualizing functions, but a good scientific calculator is often sufficient and sometimes faster for pure calculations.
• The Digital SAT: The digital SAT includes a built-in graphing calculator (Desmos), but you can still bring your own approved handheld device. Many students prefer using the physical calculator they’ve practiced with.

Frequently Asked Questions (FAQ)

Can I use my phone as a calculator?

No. Phones, smartwatches, tablets, and laptops are strictly prohibited from being used as calculators.

What happens if I bring a prohibited calculator?

The test proctor will not allow you to use it. You will have to take the Math Test – Calculator section without a calculator, potentially putting you at a significant disadvantage.

Do I need to clear my calculator’s memory?

Yes, you must remove any stored programs, documents, and especially any software that adds CAS-like functionality.

Is the TI-89 or TI-92 allowed?

No. These models, along with the TI-Nspire CAS, are explicitly banned because they contain Computer Algebra Systems.

What is the best calculator for the SAT?

The TI-84 Plus series is widely recommended due to its balance of features, ease of use, and widespread approval. However, the best one is the approved model you know how to use best.

Can you use a calculator on the PSAT?

Yes, the calculator policy for the PSAT is generally the same as for the SAT.

Can I bring a backup calculator?

Yes, you can bring a backup calculator. It must also be an approved model and must be kept under your desk, not in your bag.

Do test centers provide calculators?

No, you must bring your own calculator. Test centers do not provide them, and sharing is not allowed.
