SAT II Math Calculator Policy Tool
SAT Calculator Policy Calculator
This tool helps you understand the official College Board policy regarding the use of multiple calculators during an SAT Subject Test in Mathematics.
The policy is generally the same for both Math Level 1 and Level 2.
This refers to how many are actively in use, not including backups stored under your chair.

An In-Depth Guide to “Can We Use 2 Calculators in SAT II Math?”
The question of “can we use 2 calculators in SAT II math” is a common point of confusion for students preparing for the SAT Subject Tests. The short answer involves nuance: you can bring more than one calculator to the test center, but you can only use one at a time. This guide provides a definitive answer based on College Board policies and offers strategic advice for test day.
What is the SAT II Math Calculator Policy?
The “SAT II” exams are formally known as the SAT Subject Tests. While the College Board has discontinued the SAT Subject Tests for students in the United States, they may still be used in specific contexts for international students for university admissions. The calculator policy for these tests was designed to ensure fairness and prevent any student from having an unfair technological advantage.
The core of the policy is that a student is permitted to have **one and only one calculator on their desk** during the exam. You are, however, allowed to bring a backup calculator. This backup device must be stored under your chair and cannot be accessed unless your primary calculator malfunctions. Even then, you must get permission from the proctor before switching.
The “Formula” for Calculator Allowance
Think of the rule not as a mathematical formula, but as a logical one. The “calculation” performed by a test proctor to determine if your setup is valid is simple:
IF (Calculators_on_Desk > 1) THEN Policy_Violation = True
This single rule is the most critical part of the policy. You cannot use a scientific and a graphing calculator simultaneously to speed up different types of problems. You must choose one to be your active device.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Active Calculator | The calculator on your desk, ready for use. | Device Count | 1 |
| Backup Calculator | A spare, approved calculator stored under your chair. | Device Count | 0 – 1 (or more, but 1 is typical) |
| Permitted Actions | Using the active calculator for the exam. | N/A (Boolean) | Yes/No |
| Prohibited Actions | Using two calculators at once; sharing a calculator. | N/A (Boolean) | Yes/No |
Practical Examples
Example 1: The Compliant Student
- Inputs: Student brings a TI-84 (graphing) and a TI-30X (scientific).
- Action: Places the TI-84 on the desk and the TI-30X under the chair.
- Result: This is perfectly within the rules. If the TI-84’s batteries die, the student can ask the proctor for permission to switch to the backup.
Example 2: The Non-Compliant Student
- Inputs: A student places both a graphing and a scientific calculator on their desk, hoping to use one for graphing and the other for quick calculations.
- Action: The proctor sees two calculators on the desk.
- Result: The proctor will require the student to put one calculator away. This is a policy violation that can cause stress and lost time.
How to Use This SAT Calculator Policy Calculator
Our tool simplifies this policy into a clear yes/no answer.
- Select Your Test: Choose either Math Level 1 or 2. The policy is the same.
- Select Your Intent: Choose how many calculators you want to use *at the same time*. This is the key question.
- Review the Result: The calculator instantly provides a clear “Permitted” or “Not Permitted” result based on the College Board’s rules.
- Understand the Rationale: The “Policy Analysis Steps” break down the logic behind the decision, helping you understand *why* the rule exists.

Key Factors That Affect the SAT Calculator Policy
While the “one calculator on the desk” rule is firm, several related factors are crucial for test day.
- Approved Calculator List: Not all calculators are allowed. Devices with QWERTY keyboards, wireless communication, or those that need to be plugged in are prohibited. Check the official list of approved graphing calculators.
- CAS vs. Non-CAS: Some tests, like the ACT, ban Computer Algebra System (CAS) calculators. Historically, the SAT has been more lenient, but policies can change. As of 2025, CAS calculators are no longer permitted on the SAT.
- Proctor Discretion: Proctors have the final say. If you need to switch to a backup, you must raise your hand and wait for permission.
- Test Type: The calculator policy applies to the SAT Subject Tests in Mathematics Level 1 and 2. The main SAT test has its own sections, including a no-calculator portion.
- Battery Life: The policy allows only battery-operated devices. Ensure you have fresh batteries to avoid needing your backup.
- Digital SAT Changes: The new digital SAT includes a built-in Desmos graphing calculator, changing the dynamic for future test-takers, but this does not apply to the paper-based Subject Tests.

Frequently Asked Questions (FAQ)
Yes, you can bring two (or more) approved calculators. However, only one can be on your desk at any time. The other(s) must be stored under your chair as backups.
The primary reason is as a backup in case your main calculator’s batteries die or it malfunctions. It is strongly recommended to have a backup.
Yes. Both your primary and backup calculators must be on the College Board’s approved list. The proctor may inspect both before the test begins.
You can, but not freely. You would have to request permission from the proctor to swap the calculator on your desk with the one under your chair, which costs time. It is not a recommended strategy for optimizing problem-solving.
The general principle of one calculator at a time is the same. However, the regular SAT has a “No-Calculator” section where no calculator is allowed on your desk at all. The Math Subject Tests allow a calculator for the entire duration.
A proctor will instruct you to put one away. Depending on the circumstances, this could be considered an attempt to cheat, which could lead to dismissal and score cancellation. It is not worth the risk.
No. Most are, but some are explicitly banned (e.g., those with QWERTY keyboards like the TI-92). Always check the latest official SAT Calculator Policy on the College Board website.
Yes, calculator covers must be kept under your desk and not on it during the test.
