Graphing Calculator College Board: What You Need

The College Board does not sell or endorse a specific graphing calculator, but it maintains a strict list of approved models for SAT, PSAT, and AP exams. You can use any calculator on that list, provided it meets the board’s rules on functionality and is used during the permitted sections. This article explains the approved list, the rules, and how to choose a model that fits both your exam and your math classes.

What the College Board Actually Requires

The College Board’s calculator policy is straightforward: for the SAT, PSAT/NMSQT, PSAT 10, and PSAT 8/9, you may use any graphing calculator from its approved list. The list includes models from Texas Instruments (TI-84 Plus, TI-Nspire CX), Casio (fx-9750GII, fx-CG50), and Hewlett-Packard (HP Prime). The board updates the list occasionally, so always check the official PDF before exam day. For AP exams, the policy is similar but varies by subject: most math and science AP tests allow a graphing calculator, but some (like AP Statistics) have specific rules about what you can do with it.

How the Approved List Works

The list is not a ranking; it is a binary yes/no. Any calculator on it is permitted, and any calculator not on it is banned, regardless of how similar it looks. The board tests each model for three things:

• No QWERTY keyboard: The calculator must not have a full alphabetic keyboard, to prevent typing essays or notes.
• No wireless or internet capability: Bluetooth, Wi-Fi, and cellular features are disallowed, even if disabled.
• No external storage or apps: You cannot load notes, PDFs, or custom programs that give an unfair advantage.

Models that fail any of these tests are banned, even if they are popular. For example, the TI-89 and TI-Nspire CX CAS are not allowed because they have a computer algebra system (CAS) and external storage. The standard TI-Nspire CX (non-CAS) is allowed.

Choosing the Right Model for You

If you are buying a calculator for the SAT and also for high school math, the best choice is usually the TI-84 Plus CE. It is the most common model in American classrooms, so teachers know it, and most test-prep materials assume you have it. The Casio fx-9750GII is a cheaper alternative with similar features, but its menu system is different, so you need to learn it separately. The HP Prime is powerful and fast, but its touchscreen interface is less common in schools.

Before buying, check your school’s policy: some teachers require a specific model for class, and that model must also be on the College Board list. If you already own a calculator that is not on the list, you cannot use it on test day, so you will need to borrow or buy an approved one.

Common Mistakes and Misconceptions

One common mistake is assuming that a calculator with a CAS (like the TI-Nspire CX CAS) is allowed because it is a graphing calculator. It is not. The College Board bans all CAS models because they can solve equations symbolically, which gives an unfair advantage on non-calculator sections. Another misconception is that you can use a calculator on every SAT math question. Actually, the SAT has two math sections: one where calculators are allowed and one where they are not. You must put the calculator away during the no-calculator section, or your score may be canceled.

Another frequent error is forgetting to reset the calculator before the exam. The proctor may ask you to clear the memory, and if you have saved notes or programs, that could be seen as a violation. Always bring a backup calculator and fresh batteries, because a dead calculator is not an excuse for extra time.

Costs and Where to Buy

Graphing calculators are expensive, typically ranging from $50 for a used older model to $150 for a new TI-84 Plus CE. Casio models are often cheaper, around $30–$70. You can buy them at office supply stores, online retailers, or from your school’s bookstore. Some schools offer rental programs, so ask your math department first. Buying used is a good option, but check that the model is on the current approved list and that the screen and buttons work properly.

If you are on a tight budget, consider a scientific calculator instead, but note that the SAT math section has questions that are much easier with graphing (like finding intersections or roots). A scientific calculator will work for basic arithmetic, but you will be at a disadvantage for some questions.

Alternatives to a Graphing Calculator

For the SAT, you are not required to use a graphing calculator; you can use any approved scientific calculator. The approved list includes many scientific models like the TI-30X IIS. However, graphing calculators are recommended because they let you graph equations, find zeros, and compute statistical values quickly. If you are taking AP Calculus or AP Statistics, a graphing calculator is almost essential, as the exams assume you have one.

There are also online graphing calculators (like Desmos), but they are not allowed on the SAT or AP exams because they are not physical devices. The College Board does offer a built-in graphing calculator in the digital SAT app, but only for the digital test format; the paper test still requires a physical calculator.

How to Prepare for Test Day

Once you have an approved calculator, practice with it. Do not use a calculator you have never used before on exam day. Learn the key functions: graphing, table, statistics, and solving equations. For the SAT, you should also know when not to use a calculator, since mental math is sometimes faster. On the day of the test, bring your calculator fully charged (if it has a rechargeable battery) or with fresh batteries, and have a backup just in case.

If you are taking the digital SAT, the test app has a built-in calculator, but you can still bring your own. The proctor will tell you when calculators are allowed, and you must follow the exact rules or your test may be invalidated.

Frequently Asked Questions

Is the TI-84 Plus CE allowed on the SAT?

Yes, the TI-84 Plus CE is on the College Board’s approved list and is one of the most popular models used. It has no CAS, no QWERTY keyboard, and no wireless features, so it meets all requirements.

Can I use a TI-Nspire CX CAS on the SAT?

No, the TI-Nspire CX CAS is banned because it has a Computer Algebra System (CAS) that can solve equations symbolically. The non-CAS version (TI-Nspire CX) is allowed.

Do I need a graphing calculator for the SAT?

No, you can use any approved scientific calculator. However, a graphing calculator is recommended because it can graph functions, find intersections, and handle statistics, which can save time on certain questions.

Can I use a calculator on the no-calculator SAT math section?

No, you must put your calculator away during the no-calculator section. Using it there is a violation and can lead to your score being canceled.

Are there any free alternatives to a graphing calculator for the SAT?

The digital SAT includes a built-in graphing calculator in the test app, so if you take the digital test, you do not need to bring a physical one. For the paper test, you must bring your own approved device.

How do I know if my calculator is on the approved list?

Check the official College Board website for the current list of approved calculators. The list is updated periodically, so always verify before exam day. If your model is not listed, it is not allowed.
