What are SAT Allowed Calculators?
SAT allowed calculators are handheld, battery-powered devices that meet the specific policy requirements set by the College Board for use on the Math section of the SAT. The policy is designed to ensure fairness and prevent any student from having an unfair technological advantage. While students have access to an embedded Desmos graphing calculator within the digital testing app (Bluebook), they are also permitted to bring their own device. Understanding the list of SAT allowed calculators is a critical part of test preparation.
This policy primarily affects students taking the SAT who wish to use a physical calculator they are familiar with. It is a common misconception that all graphing calculators are banned; in reality, most are permitted. The key is that the device must not have specific prohibited features, such as a Computer Algebra System (CAS). Navigating the rules for SAT allowed calculators ensures you won’t face any issues on test day.
SAT Allowed Calculators: The Rules Explained
Instead of a mathematical formula, the determination of SAT allowed calculators follows a logical rule-set based on features. A calculator is deemed “prohibited” if it possesses any one of the features listed in the table below. If it has none of these prohibited features, it is generally allowed. This is the core logic this page’s calculator uses.
| Feature (Variable) | Meaning | Status | Typical Models |
|---|---|---|---|
| Computer Algebra System (CAS) | Can manipulate algebraic expressions symbolically. | Prohibited | TI-89, TI-Nspire CAS, HP Prime |
| QWERTY Keyboard | Has a typewriter-style keyboard. | Prohibited | TI-92 Plus |
| Wireless/Internet | Can connect to the internet, Bluetooth, or cellular networks. | Prohibited | Any smartphone or advanced device |
| Stylus or Pen-Input | Requires a stylus to operate the screen. | Prohibited | Casio ClassPad series |
| External Power | Needs to be plugged into an electrical outlet to function. | Prohibited | N/A (Laptops, etc.) |
| Noise / Paper Tape | Makes sounds or prints calculations on a roll of paper. | Prohibited | Printing calculators |
Practical Examples of SAT Allowed Calculators
Understanding the rules is easier with real-world examples. Here’s how two common calculators stack up against the policy for SAT allowed calculators.
Example 1: The TI-84 Plus CE (Allowed)
- Features: Graphing capability, rechargeable battery, no CAS, no QWERTY keyboard.
- Analysis: The TI-84 Plus CE is one of the most popular SAT allowed calculators. It is a powerful graphing calculator but crucially lacks a Computer Algebra System (CAS) and other forbidden features like a QWERTY keyboard or internet access.
- Calculator Input: You would leave all “prohibited” feature boxes unchecked.
- Result: ALLOWED.
Example 2: The TI-89 Titanium (Prohibited)
- Features: Advanced graphing, QWERTY keyboard, and a powerful Computer Algebra System (CAS).
- Analysis: The TI-89 is explicitly prohibited by the College Board because it includes a CAS, which can perform symbolic algebra manipulations like factoring and solving for variables. This gives a user an unfair advantage according to the test rules.
- Calculator Input: You would check the “Computer Algebra System (CAS)?” box.
- Result: NOT ALLOWED. Reason: Contains a Computer Algebra System (CAS).
How to Use This SAT Allowed Calculators Checker
This tool simplifies the process of checking your device against the official College Board policy. Following these steps will help you determine if your model is one of the SAT allowed calculators.
- Identify Your Calculator’s Features: Look at your calculator. Does it have a “CAS” label? Does it have a typewriter-style keyboard? Can it connect to Wi-Fi?
- Select Features in the Tool: For each feature your calculator possesses, click the corresponding checkbox in the form above. Be honest about all features.
- Review the Instant Result: The result box will immediately update. It will state “ALLOWED” in green or “NOT ALLOWED” in red.
- Understand the Reason: If your calculator is not allowed, the tool will state the specific feature that violates the policy. This is crucial information. For more help, see our math section tips.
- Reset and Compare: Use the “Reset” button to clear the form and test another calculator model or re-evaluate your own.
Key Factors That Define SAT Allowed Calculators
The College Board’s policy on SAT allowed calculators is based on a few core principles. Understanding these factors will help you make the right choice for test day.
- Fairness: The primary goal is to create a level playing field. Features like a CAS can solve problems for the student, which tests the calculator’s power, not the student’s mathematical reasoning.
- No Symbolic Manipulation: The ban on CAS is the most significant rule. Calculators that can factor polynomials, solve for variables algebraically, or find symbolic derivatives are forbidden. This is a core tenet of the policy for SAT allowed calculators.
- No External Communication: The strict prohibition on internet, Bluetooth, or any wireless communication is to prevent cheating. For a secure testing environment, no device can be allowed to send or receive information.
- Standard Input Methods: The ban on QWERTY keyboards and styluses ensures that calculators remain tools for calculation, not text entry or advanced computer-like interaction. This is a key part of the graphing calculator rules.
- Test Security: Rules against calculators with cameras, audio recorders, or those that need external power prevent any form of test content from being recorded or removed from the test center.
- Physical Form Factor: The calculator must be a handheld device. Laptops, tablets, and phones are not permitted, reinforcing the boundary between a calculation tool and a general-purpose computer. Our best calculator for SAT guide can help you choose.
Frequently Asked Questions (FAQ)
- 1. Is the TI-84 Plus allowed on the SAT?
- Yes, all versions of the TI-84 Plus (including the CE model) are allowed because they do not have a built-in Computer Algebra System (CAS). It is one of the most popular SAT allowed calculators.
- 2. What happens if I bring a prohibited calculator to the test?
- A test proctor will inspect your calculator. If it’s found to be on the prohibited list, you will not be allowed to use it. You may have to take the math section without a calculator, or in some cases, you could be dismissed from the test.
- 3. Do I need to clear my calculator’s memory?
- Yes, the College Board requires you to remove any stored documents and programs that have algebra functionality. It’s best practice to clear the memory before you go to the test center.
- 4. Are all scientific calculators allowed?
- Yes, all scientific calculators are permitted as long as they do not have any of the specifically prohibited features, like a QWERTY keyboard or wireless capabilities.
- 5. Can I use the calculator on my smartphone?
- No. All smartphones, smartwatches, tablets, and laptops are strictly forbidden for use as calculators. Using one would lead to immediate dismissal.
- 6. What is a Computer Algebra System (CAS) and why is it banned?
- A CAS is a sophisticated program that can manipulate mathematical expressions symbolically. For example, it can solve `2x + 5 = 15` and give you the answer `x = 5`. This is banned to ensure students are tested on their ability to solve these problems, not their calculator’s. This is the most important rule for SAT allowed calculators.
- 7. Is the built-in Desmos calculator good enough?
- Yes, the Desmos calculator provided in the Bluebook testing app is a powerful graphing calculator that is sufficient for all questions on the SAT. However, if you are more comfortable with your own physical calculator, it’s wise to bring one from the list of SAT allowed calculators. Consult our digital SAT guide for more info.
- 8. Do I really need a graphing calculator?
- While not strictly necessary (a scientific calculator is allowed), a graphing calculator can be a significant advantage for visualizing functions, finding intercepts, and solving complex problems more quickly. A good device is a key part of any SAT test day checklist.
