What Are Calculators Allowed for SAT?
The term “calculators allowed for SAT” refers to the specific handheld models that the College Board permits students to use during the Math section of the SAT exam. To ensure fairness, the SAT calculator policy outlines strict rules about which devices are acceptable and which are prohibited. Most graphing calculators and all scientific calculators are allowed, but they must not have features like internet access, computer algebra systems (CAS), or QWERTY keyboards. Understanding these rules is crucial for any student preparing for the test, as using a prohibited device can lead to dismissal and score cancellation.
Who Needs to Check This?
Any student planning to take the SAT, as well as their parents and educators, should be familiar with the list of calculators allowed for SAT. It’s your responsibility to bring an approved, working calculator on test day. Test centers will not provide them. This checker and guide help you confirm your device is compliant and avoid any test-day surprises.
Common Misconceptions
A common mistake is assuming any graphing calculator is fine. However, many advanced models, especially those with a Computer Algebra System (CAS), are explicitly banned. For instance, the TI-Nspire CX CAS is prohibited, while the standard TI-Nspire CX is allowed. Another misconception is that you need the most expensive calculator; in reality, a familiar scientific calculator is often sufficient for the problems you’ll encounter. Familiarity with your own device is more important than having the most features.
How the College Board Determines Approved Calculators
The College Board’s policy on calculators allowed for SAT isn’t based on brand names but on functionality. The goal is to level the playing field and prevent any student from having an unfair advantage. The rules are designed to ensure the test measures mathematical reasoning, not the ability to operate a mini-computer. Prohibited features are those that solve problems symbolically or connect to outside information.
Key Approval Criteria Table
This table breaks down the features that determine if a calculator is approved. A device is generally prohibited if it has any of the “Not Allowed” features.
| Feature/Capability | Status | Reasoning | Typical Range/Example |
|---|---|---|---|
| Basic & Scientific Functions | Allowed | Essential for calculations (trig, logs, exponents). | TI-30X, Casio fx-115ES |
| Graphing Capability | Allowed | Permitted for visualizing functions. | TI-84 Plus, Casio fx-9750GII |
| Computer Algebra System (CAS) | Prohibited | Solves algebraic equations symbolically, giving an unfair advantage. | TI-89, HP Prime, TI-Nspire CAS |
| QWERTY Keyboard | Prohibited | Looks like a communication device and is not allowed. | Calculators with typewriter-like keys. |
| Wireless/Internet Access | Prohibited | Prevents cheating by accessing external information. | Any device with Wi-Fi, Bluetooth, or cellular data. |
| Stylus or Pen Input | Prohibited | Devices with touch screens and styluses are not permitted. | Casio ClassPad series. |
| External Power Source | Prohibited | Only battery-operated calculators are allowed. No power cords. | Calculators that need to be plugged in. |
Practical Examples (Real-World Use Cases)
Example 1: The Standard Graphing Calculator
A student has a TI-84 Plus CE. They enter “Texas Instruments” and “TI-84 Plus CE” into the checker.
- Input: Brand: Texas Instruments, Model: TI-84 Plus CE
- Output: APPROVED. This model is a standard graphing calculator and is fully compliant.
- Interpretation: The student can confidently bring this calculator to the test. It provides all the necessary graphing and scientific functions without any prohibited features. This is one of the most common calculators allowed for SAT.
Example 2: The Banned CAS Calculator
A student’s older sibling hands them a TI-89 Titanium. They check its eligibility.
- Input: Brand: Texas Instruments, Model: TI-89 Titanium
- Output: PROHIBITED. This calculator has a Computer Algebra System (CAS).
- Interpretation: Despite being a Texas Instruments calculator, this model is not allowed because its CAS functionality can solve algebraic equations symbolically. The student must find a different, non-CAS calculator for the test. You can get help with your studies with our SAT math help guide.
How to Use This Calculator Checker
This tool provides a quick way to check against the list of calculators allowed for SAT. Follow these simple steps for an instant result.
- Select the Brand: Choose your calculator’s brand (e.g., Texas Instruments, Casio) from the dropdown menu.
- Enter the Model: Type the model number into the text field. Be as precise as possible.
- Click “Check Eligibility”: The tool will analyze your input and provide an immediate status.
- Review the Results: The primary result will show “APPROVED,” “NOT APPROVED,” or “PROHIBITED.” The intermediate values will explain why, based on features like CAS or a QWERTY keyboard.
Reading the results helps you understand the policy on calculators allowed for SAT and make an informed decision. For more info on the test itself, see our digital SAT guide.
Key Factors That Affect Calculator Approval
Several key factors determine whether a calculator is on the approved list. Understanding these will help you choose the right device and ensure you are compliant with the rules for calculators allowed for SAT.
- Computer Algebra System (CAS): This is the most common reason for a calculator to be banned. CAS can perform symbolic manipulation (e.g., factor x²-1 into (x-1)(x+1)), which is considered an unfair advantage.
- QWERTY Keyboard: Any calculator with a typewriter-style keyboard is prohibited as it resembles a communication device.
- Wireless Capability: Calculators with Wi-Fi, Bluetooth, or any form of wireless communication are strictly forbidden to prevent cheating.
- Stylus/Pen Input: Devices that require a stylus or have a touch screen for writing are not allowed. This includes many PDA-like devices.
- Power Cords: All calculators must be battery-operated. Devices that need to be plugged into a wall outlet are not permitted in the test room.
- Noise and Printing: Calculators that make noise or print to a paper tape are banned as they can distract other test-takers.
When selecting from the many calculators allowed for SAT, always double-check these features. If you are also preparing for the ACT, check out the ACT calculator rules, as they can differ.
Frequently Asked Questions (FAQ)
If a proctor discovers you have a prohibited calculator, you will be dismissed from the test, and your scores will be canceled. It is critical to verify your device is on the list of calculators allowed for SAT beforehand.
No, it’s not a requirement. All questions on the SAT can be solved without a calculator. However, a graphing calculator (or the built-in Desmos calculator on the digital SAT) can be a very helpful tool for solving problems more quickly, especially for functions and graphs. A good PSAT study plan will help you practice when to use a calculator effectively.
No. Smartphones, smartwatches, laptops, and any device with wireless capabilities are strictly prohibited. You must use a physical, handheld calculator from the approved list of calculators allowed for SAT.
The “CAS” is the key difference. The TI-Nspire CX is an approved graphing calculator. The TI-Nspire CX CAS has a Computer Algebra System and is therefore banned from the SAT. Always check for “CAS” in the model name.
Yes, four-function calculators are allowed, but they are not recommended. They are very limited and will not be helpful for the more complex trigonometry and algebra problems on the test.
You are responsible for ensuring your calculator is in working order. It’s highly recommended to install fresh batteries the day before the test. Proctors will not supply batteries or replacement calculators.
No, sharing calculators is not permitted under any circumstances. This is a strict rule to maintain test security.
If your calculator is not explicitly listed as approved or banned, you should check it against the feature-based rules (no CAS, no QWERTY, etc.). When in doubt, it’s safest to purchase a model that is explicitly listed as one of the calculators allowed for SAT, such as a TI-84 Plus.
