Complete Guide: What Calculators Are Allowed on the SAT (2024 Rules)
The SAT calculator policy is strictly enforced by the College Board to maintain test fairness. Understanding which calculators are permitted—and which are prohibited—can mean the difference between a smooth testing experience and potential disqualification. This comprehensive guide covers everything you need to know about SAT calculator rules, approved models, and expert recommendations.
Official SAT Calculator Policy Overview
According to the College Board’s official calculator policy, calculators are only permitted during the Math Test — Calculator portion of the SAT. The policy divides calculators into three categories:
- Permitted Calculators: Most graphing calculators, scientific calculators, and four-function calculators (without prohibited features).
- Permitted with Modifications: Calculators with prohibited features that can be disabled (e.g., QWERTY keyboards covered with tape).
- Prohibited Calculators: Calculators with prohibited features that cannot be disabled, or models on the College Board’s banned list.
Permitted Calculator Features
Your calculator must meet the following criteria to be allowed on the SAT:
- Does not have a QWERTY keyboard (unless covered/disabled)
- Does not have wireless (Wi-Fi/Bluetooth) capabilities
- Does not have a computer algebra system (CAS)
- Does not have a pen/stylus input or touchscreen
- Is not on the College Board’s prohibited list
- Is battery-powered (no electrical outlets allowed)
- Does not make noise or have a paper tape
Approved Calculator Models (2024)
The following calculator models are generally permitted on the SAT (always verify with the College Board for updates):
| Brand | Permitted Models | Notes |
|---|---|---|
| Texas Instruments | TI-84 Plus, TI-84 Plus CE, TI-83 Plus, TI-89 Titanium (with restrictions), TI-Nspire (non-CAS) | TI-89/Titanium/Voyage 200 require CAS disabled |
| Casio | fx-9750GII, fx-9860GII, fx-CG50, fx-300ES Plus | ClassPad 300/330 prohibited (has CAS) |
| HP | HP Prime (non-CAS mode), HP 35s, HP 12C | Must disable CAS on HP Prime |
| Sharp | EL-9600, EL-9900, EL-W516 | No touchscreen models allowed |
Prohibited Calculator Models
The following calculators are explicitly banned from the SAT:
| Prohibited Feature/Model | Reason for Prohibition |
|---|---|
| TI-89 Titanium (with CAS enabled) | Computer Algebra System (CAS) |
| TI-Nspire CX CAS | Computer Algebra System (CAS) |
| Casio ClassPad 300/330 | Computer Algebra System (CAS) |
| HP 48GII, HP 49G, HP 50G | Computer Algebra System (CAS) |
| Calculators with QWERTY keyboards (unless covered) | Potential for typing notes |
| Calculators with Wi-Fi/Bluetooth | Risk of communication |
| Laptops, tablets, or phones | Not dedicated calculators |
How to Prepare Your Calculator for the SAT
- Check the batteries: Bring fresh batteries and extras. Test centers don’t provide replacements.
- Clear memory: Some proctors may require you to clear your calculator’s memory before the test.
- Disable prohibited features: If your calculator has CAS or a QWERTY keyboard, ensure these are disabled or covered.
- Practice with your calculator: Familiarize yourself with its functions to avoid wasting time during the test.
- Bring a backup: The College Board recommends bringing a second approved calculator in case of failure.
Common Myths About SAT Calculators
Several misconceptions circulate about SAT calculator policies. Here are the facts:
- Myth: “Graphing calculators are required for the SAT.”
Fact: While helpful, graphing calculators are not required. Scientific and four-function calculators are also permitted. - Myth: “You can use any calculator as long as it’s not on the prohibited list.”
Fact: Even if a calculator isn’t explicitly banned, it may still be prohibited if it has disallowed features (e.g., CAS, Wi-Fi). - Myth: “The SAT provides calculators.”
Fact: You must bring your own approved calculator. None are provided at the test center. - Myth: “You can share a calculator with another test-taker.”
Fact: Sharing calculators is strictly prohibited during the test.
Expert Recommendations for SAT Calculators
Based on performance, reliability, and compliance with SAT rules, here are our top recommendations:
- Best Overall: Texas Instruments TI-84 Plus CE
Pros: Widely used, reliable, no CAS, permitted on all standardized tests.
Cons: Higher cost (~$120–$150). - Best Budget Option: Casio fx-300ES Plus
Pros: Affordable (~$15–$20), scientific (non-graphing), fully compliant.
Cons: Limited graphing capabilities. - Best for Advanced Users: Texas Instruments TI-Nspire CX (non-CAS)
Pros: Powerful graphing, color display, permitted if CAS is disabled.
Cons: Expensive (~$150), requires CAS disable confirmation. - Best for Simplicity: Sharp EL-501XBWH
Pros: Basic four-function, ultra-affordable (~$10), no risk of prohibition.
Cons: Limited functionality for advanced math.
What Happens If You Bring a Prohibited Calculator?
If you bring a prohibited calculator to the SAT, the following may occur:
- The test proctor will confiscate the calculator before the test begins.
- You will not be allowed to use it during the exam.
- If you attempt to use it during the test, you may be dismissed and your scores canceled.
- In cases of suspected cheating (e.g., using a calculator with Wi-Fi), the College Board may ban you from future tests.
Always double-check the official SAT calculator policy before test day. When in doubt, contact the College Board directly or bring a backup calculator.
Frequently Asked Questions (FAQ)
Q: Can I use a calculator on both math sections of the SAT?
A: No. Calculators are only permitted on the Math Test — Calculator portion. The other math section (Math Test — No Calculator) prohibits all calculator use.
Q: Are solar-powered calculators allowed?
A: Yes, as long as they don’t have prohibited features. However, test centers may not have optimal lighting, so battery-powered calculators are recommended.
Q: Can I use a calculator app on my phone?
A: No. Phones are strictly prohibited during the test, even for calculator apps.
Q: What if my calculator breaks during the test?
A: The test center will not provide a replacement. This is why bringing a backup calculator is strongly advised.
Q: Are calculators with color displays allowed?
A: Yes, as long as they don’t have prohibited features (e.g., TI-84 Plus CE has a color display and is permitted).
