The graphing calculator has long been a fixture of high school supply lists. By the fall of 2026 the three tests that justified the purchase for many families—the SAT, AP exams and the ACT—each put a graphing calculator inside the testing software. The College Board says 97% of SAT takers in the class of 2025 took the digital SAT, which runs in its Bluebook app with Desmos built in.
That has not ended the handheld. Texas Instruments launched a new flagship, the TI-84 Evo, in April 2026, and all three test makers still let students bring approved models. The buying question is narrower than it used to be: which tests and classes still reward owning one, and which type the rules allow.

Built-in Desmos now reaches nearly every SAT taker
The College Board says 97% of SAT takers in the class of 2025 used the digital test, which embeds a Desmos graphing calculator, and its AP policy lists a built-in Desmos calculator for every exam that permits one. Handhelds remain allowed, and Texas Instruments launched a new flagship in April 2026, which keeps the score below the top band.

What the tests now build in
The SAT now runs in the College Board’s Bluebook app, and its calculator policy says Bluebook “contains an embedded Desmos calculator with two options—graphing or scientific.” A calculator is allowed on the Math section and not on Reading and Writing. More than 2 million students in the class of 2025 took the SAT at least once, and 97% of them took the digital version, according to the College Board.
AP exams followed. In May 2025 the College Board moved 28 of its 36 AP subjects to Bluebook, with more than 3 million students expected to take nearly 6 million digital or hybrid exams. Its AP calculator policy lists a built-in Desmos calculator for every exam that permits a calculator, from Biology and Chemistry to Calculus, Statistics and Macroeconomics. For Calculus AB, Calculus BC and Precalculus, Desmos appears only in the calculator-required parts, because those exams keep sections where no calculator is allowed.
The ACT splits by format. Its policy says students taking the ACT online “have access to the Desmos graphing calculator built into the testing platform during the Math section,” while paper testers bring their own. ACT also states that all of its math problems can be solved without a calculator.
On the SAT and on calculator-permitted AP exams, a student with no calculator still has a graphing tool on screen.
What the rules still allow in your hand
None of the three tests has banned handhelds. The SAT policy tells students, “We encourage you to use the calculator that is most familiar to you,” allows graphing, scientific and four-function models, and bars computer algebra system (CAS) models, QWERTY keyboards, wireless or cellular connectivity and phone calculator apps. The College Board says it no longer maintains a list of specifically permitted graphing models for the SAT, so the student has to check the features.
AP rules vary by subject, and a student may bring up to two permitted handhelds. The current policy page requires a graphing model for Calculus, Precalculus and Statistics, allows four-function, scientific or graphing models for Chemistry and Physics, limits Biology and Environmental Science to four-function or scientific models, and allows only four-function models on the economics and business exams. The page also flags changes for the AP exams that follow the May 2026 administration: graphing calculators are not allowed in Biology and Environmental Science, and nongraphing calculators are not allowed in Statistics.
The ACT keeps a named prohibited list. It covers all TI-89 and TI-92 models, the TI-Nspire CAS, the HP Prime and several Casio ClassPad models; the non-CAS TI-Nspire is permitted.
| Test | Built-in calculator | Handheld you may bring |
|---|---|---|
| Digital SAT | Desmos, graphing or scientific | Graphing, scientific or 4-function; no CAS, no QWERTY, no wireless |
| AP Calculus, Precalculus | Desmos in calculator-required parts | Graphing models, up to two |
| AP Statistics | Desmos | Graphing models, up to two |
| AP Chemistry, Physics | Desmos | 4-function, scientific or graphing |
| AP Biology, Environmental Science | Desmos | 4-function or scientific |
| ACT on paper | None | Your own; CAS models such as the TI-89 are prohibited |
Where a handheld still earns its place
The built-in tools cover test day. They do not cover homework, paper quizzes or classes where laptops stay closed. Texas Instruments leans on exactly that gap in its TI-84 Evo launch release, citing a 2025 EdWeek Research Center study in which 94% of teachers and administrators said students perform better on exams when they use the same calculator for assessment, practice and instruction, and 81% said students focus better on math with a handheld. The figures come from a release by the seller, so we read them as teacher sentiment rather than proof of better scores.
The consistency argument cuts both ways. A student who uses Desmos in class all year already practices on the tool in Bluebook, at no cost; a student whose teacher runs lessons and paper tests on a TI-84 gains more from owning one.
Paper still matters in two places: the paper ACT requires a student-supplied calculator, and AP Calculus, Precalculus and Statistics require any handheld to be a graphing model.
Buy for the classroom, not for the SAT: the SAT brings its own calculator.
What the new hardware costs
For years, handheld pricing barely moved. A 2017 CNN report, carried by CBS 58, said the TI-84 Plus generally retailed for $90 to $120, a range that had not changed since its 2004 debut. The new flagship launched above that range: when Texas Instruments launched the TI-84 Evo on April 28, 2026, Engadget reported a $160 price for individual customers, with schools quoted separately.
TI says the Evo has a processor three times faster, 50% more graphing space, a redesigned keypad, an icon-based menu, a points-of-interest trace feature and USB-C charging, and that it is approved for the ACT, SAT, IB and AP exams. It comes in seven colors. For a student comfortable on an older TI-84, those are mostly speed, screen and navigation upgrades rather than a change in what the course requires.
Below calculus, a scientific calculator covers much of the ground, and it is the most the AP allows as a handheld in Biology and Environmental Science.
Who should buy now and who should wait
Buy a graphing handheld now if a math teacher names a specific model, if the student will take the ACT on paper, or if the student is in AP Calculus, Precalculus or Statistics and wants a physical backup to the on-screen tool. Check the model against the prohibited features before paying: CAS, QWERTY keys and wireless are the common disqualifiers.
Wait, or buy a scientific model, if the student is in pre-algebra through Algebra 1 and the class already uses Desmos, or if the SAT is the only reason for the purchase. A non-CAS graphing calculator without wireless or QWERTY keys meets the SAT’s stated rules, so a model already in the household does not need replacing for the test.

Questions readers ask
Can I bring my own calculator to the digital SAT?
Yes. The College Board encourages students to use the calculator most familiar to them and allows graphing, scientific and four-function models, but bans CAS models, QWERTY keyboards, wireless connectivity and phone apps. Bluebook also includes a Desmos calculator with graphing and scientific modes.
Is Desmos available on AP Calculus?
Yes, in the calculator-required parts only. The College Board’s AP policy says Desmos is built into Bluebook for Calculus AB and BC and for Precalculus in those parts, and students may also bring up to two permitted graphing handhelds.
Is the TI-89 allowed on the ACT?
No. ACT’s calculator policy prohibits all TI-89 and TI-92 models, the TI-Nspire CAS, the HP Prime and several Casio ClassPad models. Students taking the ACT online get Desmos in the Math section.
How much does the TI-84 Evo cost?
Engadget reported a $160 price for individual customers when Texas Instruments launched the TI-84 Evo on April 28, 2026. TI says it is approved for the ACT, SAT, IB and AP exams.
