What is the SAT Calculator Policy?
The SAT calculator policy defines the rules for using a handheld calculator during the Math section of the test. The main goal is to ensure fairness and prevent any student from having an unfair advantage. While the Digital SAT now includes a built-in Desmos graphing calculator, students are still permitted to bring their own approved device. The question of **can you use two calculators on the sat** is common, and the policy addresses this directly by allowing a backup device under specific conditions. Understanding these rules, especially regarding what constitutes an approved versus a prohibited device, is a critical part of test preparation.
Who should care about this? Any student planning to take the SAT. A common misconception is that the most expensive calculator is the best. However, familiarity and compliance are far more important. Using a non-compliant calculator can lead to dismissal from the test. The question isn’t just about whether **can you use two calculators on the sat**, but whether the ones you bring are allowed.
The Logic Behind Using Two Calculators on the SAT
The “formula” for determining if **can you use two calculators on the sat** is less a mathematical equation and more a logical flowchart based on College Board rules. You can bring a primary calculator and a backup, but you cannot use them simultaneously. The backup must be stored under your desk and can only be used if the primary one fails, and only after notifying the proctor.
The core logic is as follows:
- Primary Calculator Check: Is the main calculator on the approved list and free of prohibited features (like CAS, Wi-Fi, QWERTY keyboard)? If yes, proceed. If no, it’s not allowed.
- Backup Calculator Check: If bringing a second device, does it ALSO meet all approval criteria? If yes, it’s an acceptable backup. If no, it cannot be brought into the testing room.
- Usage Rule: You can only have one calculator on your desk at a time. To switch, you must get permission from the proctor.
| Feature/Variable | Meaning | Status | Typical Range/Example |
|---|---|---|---|
| Calculator Type | The device category. | Allowed | Graphing, Scientific, Four-Function |
| Computer Algebra System (CAS) | Ability to manipulate symbolic equations. | Prohibited | TI-Nspire CAS, HP Prime |
| QWERTY Keyboard | A typewriter-style keyboard. | Prohibited | TI-92 Plus |
| Wireless/Internet | Wi-Fi, Bluetooth, or other connectivity. | Prohibited | Any smartphone or tablet |
| Power Source | How the calculator is powered. | Allowed (Battery Only) | AAA, Solar, Rechargeable Battery |
| Backup Device | A second, policy-compliant calculator. | Allowed (with conditions) | A spare TI-84 or scientific calculator |
Practical Examples (Real-World Use Cases)
Example 1: The Prepared Student
- Primary Calculator: TI-84 Plus CE (Approved Graphing Calculator).
- Backup Calculator: TI-30XIIS (Approved Scientific Calculator).
- Scenario: The student enters the test with both. The TI-30XIIS is placed under the desk. Midway through the math section, the TI-84’s battery dies. The student raises their hand, informs the proctor, and is given permission to retrieve the backup TI-30XIIS to finish the test.
- Outcome: This is a perfect example of correctly following the policy for using a backup. This student correctly understood the rules for if **can you use two calculators on the sat**.
Example 2: The Uninformed Student
- Primary Calculator: HP Prime (A powerful graphing calculator with a prohibited CAS).
- Backup Calculator: A smartphone with a calculator app.
- Scenario: The proctor identifies the HP Prime as a CAS-enabled device during check-in. The student is told they cannot use it. The smartphone is also explicitly prohibited. The student must now take the math section using only the built-in digital calculator, which they may be unfamiliar with.
- Outcome: This student is at a disadvantage for not understanding the SAT calculator policy. Their misunderstanding of the rules for if **can you use two calculators on the sat** created a stressful situation.

Key Factors That Affect Calculator Choice
Choosing the right calculator—and deciding if you need a backup—involves several factors beyond just policy. Understanding these can improve your performance and confidence on test day, especially when considering if **can you use two calculators on the sat** is the right strategy for you.
- Familiarity: The best calculator is the one you know how to use inside and out. Don’t buy a new, complex graphing calculator the week before the test. Stick with what you’ve used in your math classes.
- Battery Life: A dead calculator is a useless calculator. Ensure your device has fresh batteries before test day. This is the number one reason students ask if they **can you use two calculators on the sat**—fear of battery failure. A backup provides peace of mind.
- Graphing vs. Scientific: While not required, a graphing calculator can quickly solve complex problems, graph functions, and find intersections, which can save valuable time. A scientific calculator is sufficient but may require more steps. Check out some College Board calculator rules for more information.
- Built-in vs. Handheld: The Digital SAT offers an excellent built-in Desmos calculator. You should practice with it to see if it meets your needs. Some students prefer the tactile feel and familiar functions of their own handheld device.
- Resetting Memory: Proctors may ask you to clear the memory on your calculator. Make sure you know how to do this quickly. Storing formulas or notes is prohibited.
- Test Day Procedure: Knowing the procedure for swapping to a backup (placing it under your seat, raising your hand) prevents confusion and anxiety during the exam. This is a key part of understanding the policy on if **can you use two calculators on the sat**.
Frequently Asked Questions (FAQ)
No. You can bring a backup calculator, but only one device is allowed on your desk at a time. The backup must be stored under your chair until your primary calculator fails and you get permission from a proctor to switch.
You will not be allowed to use it. The proctor will ask you to put it away. If you don’t have an approved backup or are not comfortable with the built-in digital calculator, you will be at a significant disadvantage.
