Adhering to these general guidelines ensures you select a device that aligns with the College Board’s strict security protocols and assessment philosophy.

Permitted Technological Aids: Graphing and Scientific Calculators

The vast majority of calculators acceptable for the SAT fall into two main categories: scientific calculators and graphing calculators. Each offers a distinct set of features, and understanding their capabilities can inform your choice and preparation strategy.

Deep Dive into Graphing Calculators: Capabilities and Recommended Models

Graphing calculators are the most powerful permitted devices, offering advanced functions crucial for some higher-level math problems, particularly those involving functions, graphs, matrices, and complex equations. Their ability to visualize mathematical relationships can be a significant advantage.

Key Features of Acceptable Graphing Calculators:

Graphical Representation: They can plot functions, analyze curves, find intercepts, and determine minimum/maximum values.
Equation Solving: Advanced solvers for polynomials, systems of equations, and inequalities.
Matrix Operations: Essential for linear algebra problems.
Statistical Analysis: Regression analysis, probability distributions, and data plotting.
Programming Capabilities (with caveats): While some graphing calculators are programmable, any pre-loaded programs that could give an unfair advantage or access prohibited material must be cleared or not used. College Board staff reserve the right to inspect calculators.

Widely Accepted and Recommended Models:

Texas Instruments (TI) Series:
- TI-83 Plus / TI-84 Plus (and their various CE versions): These are arguably the most popular and recommended graphing calculators due to their widespread use in schools, extensive online tutorials, and robust functionality. The TI-84 Plus CE is a modern iteration with a color screen and rechargeable battery, highly favored by students.
- TI-Nspire (and CX/CX II versions): These are powerful calculators with a more intuitive interface and often a computer-like experience. However, the TI-Nspire CX CAS (Computer Algebra System) is not allowed if it has a QWERTY keyboard, and the TI-Nspire CAS is typically prohibited due to its symbolic manipulation capabilities that can solve problems step-by-step. The non-CAS versions, specifically the TI-Nspire CX and CX II, are generally acceptable if they don’t have prohibited features like wireless communication or a full QWERTY keyboard. Crucially, CAS versions are often disallowed due to their symbolic algebra capabilities. Always double-check the exact model’s allowed status.
Casio Series:
- Casio FX-9750GII / FX-9860GII: These are strong alternatives to the TI models, offering similar graphing and scientific functionalities at a competitive price. They are also widely accepted.
Hewlett-Packard (HP) Series:
- HP Prime: A powerful modern graphing calculator with a touch screen (though touch functionality is often disabled for testing or not a core input method) and advanced capabilities. Acceptable versions typically do not have a QWERTY keyboard or wireless features enabled.

Scientific Calculators: The Reliable Workhorses

For students who don’t require the advanced graphing capabilities or prefer a simpler interface, scientific calculators are perfectly acceptable and often sufficient for the SAT Math section. Many questions can be solved with just a scientific calculator.

Key Features of Acceptable Scientific Calculators:

Basic Arithmetic: Addition, subtraction, multiplication, division.
Exponents and Roots: Square roots, cube roots, powers.
Logarithms: Natural and common logarithms.
Trigonometric Functions: Sine, cosine, tangent, and their inverses.
Memory Functions: For storing intermediate results.
Fractions and Decimals: Conversion between them.
Parentheses: Essential for complex operations.

Widely Accepted and Recommended Models:

Texas Instruments (TI) Series:
- TI-30X IIS / TI-30XS MultiView: These are excellent, affordable, and highly functional scientific calculators, often recommended for their clear displays and user-friendly interface.
Casio Series:
- Casio FX-115ES Plus / FX-991EX (ClassWiz): These are very popular and robust scientific calculators, known for their natural display (showing fractions and square roots as they appear in textbooks) and extensive features, including basic matrix and vector calculations.
Sharp Series:
- Sharp EL-W516X: Another solid choice offering a wide range of scientific functions.

Understanding Keyboard Features and Display Requirements

Beyond functionality, the physical design of the calculator is also scrutinized.

Keyboard Layout: As mentioned, a full QWERTY keyboard (like on a computer or smartphone) is a red flag. The keys should primarily be numerical, operational, and function-specific.
Display: While color screens are allowed (e.g., TI-84 Plus CE), the display should not be capable of displaying internet content, videos, or full documents. The primary purpose of the display is to show calculations, graphs, and input/output.
Touchscreen Functionality: While some advanced calculators have touchscreens (like HP Prime), their use is generally restricted to basic input, not for browsing or complex interaction that could mimic a disallowed device. In many testing scenarios, touch input might be disabled or irrelevant.

Prohibited Devices: What to Leave at Home

Just as important as knowing what’s allowed is understanding what is strictly forbidden. Bringing a prohibited device can lead to immediate dismissal from the test, cancellation of scores, and even a ban from future College Board tests.

Smartphones, Tablets, and Other Connected Devices

This is perhaps the most obvious category of prohibited devices. Any device primarily designed for communication, internet access, or general computing is banned.

Smartphones: iPhone, Android phones, etc.
Tablets: iPad, Android tablets, Microsoft Surface, etc.
Laptops/Notebooks: Any personal computer.
Smartwatches/Wearable Technology: Apple Watch, Samsung Galaxy Watch, Fitbits, etc., are all forbidden. Even if they have calculator functions, their communication and notification capabilities make them unacceptable.
Portable Media Players: iPods, MP3 players, etc.
Electronic Listening Devices: Headphones, earbuds (wired or wireless).
Any Device with an Audio/Video Recording or Playback Function: This includes devices that could have these functions, even if you don’t intend to use them for that purpose.

Calculators with QWERTY Keyboards and Advanced Features

Certain types of calculators, even if they appear to be dedicated computing devices, are prohibited due to their advanced features or keyboard layout.

Calculators with QWERTY (typewriter-like) Keyboards: This is a firm rule. Examples include some older TI-92 or Voyage 200 models, or dedicated word processing devices. The rationale is that these keyboards could facilitate unauthorized messaging or access to stored text.
Calculators with Computer Algebra System (CAS) Capabilities (specific models): While some CAS features are integrated into acceptable graphing calculators, dedicated CAS systems that can perform symbolic manipulation (like solving algebraic equations for variables rather than just numerical outputs) are often prohibited. The TI-Nspire CAS and some HP CAS models fall into this category, as they can “solve” problems in a way that bypasses genuine understanding. Always verify if your specific CAS model is allowed.
Calculators with Wireless Communication (Bluetooth, Wi-Fi, cellular): Even if a calculator has advanced mathematical features, if it can connect wirelessly, it’s out.
Calculators with Pen-Input or Stylus-Input Capabilities that Allow Text Entry: Devices designed for note-taking or drawing in a way that mimics a digital notepad are disallowed.
Calculators that Require an Electrical Outlet: All acceptable calculators must be battery-powered.

The “No-Go” List: Specific Examples and Why They’re Banned

While the College Board doesn’t publish an exhaustive list of every prohibited model, understanding the types of banned calculators is key.

TI-89, TI-92, TI-Nspire CAS (often): These models, especially older versions or CAS variants, are frequently cited as problematic due to their symbolic manipulation capabilities or QWERTY-like interfaces.
HP 48GII (often): Similar to the TI-89, its advanced features and potential for symbolic manipulation often lead to it being prohibited.
Any calculator integrated into a phone, tablet, or smartwatch.
Any calculator that beeps, talks, or makes any noise.

The fundamental principle is that the device should aid computation and visualization, not provide solutions directly or enable communication/information access beyond its numerical functions. When in doubt, err on the side of caution and opt for a simpler, universally accepted model like the TI-84 Plus CE or a reliable scientific calculator.

Optimizing Your Calculator Strategy for the SAT Math Section

Having the right calculator is only half the battle; knowing how to use it effectively and responsibly on test day is equally important.
