Which TI Calculator for the SAT® and Why?
TI Calculators Allowed on the SAT®
Just about every TI calculator is approved for use on the calculator portion of the SAT® exam.
Here is the list from the SAT® calculator policy:
- TI-73 Explorer™ graphing calculator
- TI-80 graphing calculator
- TI-81 graphing calculator
- TI-82 graphing calculator
- TI-83 graphing calculator and TI-83 Plus graphing calculator
- TI-83 Plus Silver Edition graphing calculator
- TI-84 Plus graphing calculator and TI-84 Plus T graphing calculator
- TI-84 Plus CE graphing calculator and TI-84 Plus CE-T graphing calculator
- TI-84 Plus Silver Edition graphing calculator
- TI-84 Plus C Silver Edition graphing calculator
- TI-85 graphing calculator
- TI-86 graphing calculator
- TI-89 graphing calculator (this is a CAS calculator)
- TI-89 Titanium graphing calculator (this is a CAS calculator)
- TI-Nspire™ graphing calculator and TI-Nspire™ CX graphing calculator
- TI-Nspire™ CAS graphing calculator and TI-Nspire™ CX CAS graphing calculator
Did you notice that super-powerful CAS (stands for Computer Algebra System) calculators are allowed? In addition to finding numeric answers, a CAS calculator provides algebraic answers in simplest form and can perform calculus commands, such as integrals and derivatives.
Which Calculators are Not Allowed?
The SAT® policy also lists functionality that is not permitted on the exam, including:
- Models that can access the Internet, have wireless, Bluetooth, cellular, audio/video recording and playing, camera or any other smartphone type feature
- Models that have a typewriter-like keyboard, pen input or stylus (more on this below)
- Models that use electrical outlets, make noise or have a paper tape (The very first TI calculator, TI-2500 Datamath, was a plug-in model that could add, subtract, multiply and divide — all for the low retail price of $149.95 in 1972. Adjusting for inflation, that is a cost of more than $900 in 2018.)
The TI-92 graphing calculator is the only TI model I've ever used in the classroom that is not allowed on the calculator portion of the SAT®. Why? It has a QWERTY (typewriter-like) keyboard. This behemoth of a calculator weighed in at 17.9 ounces compared to the TI-84 Plus CE calculator that weighs a measly 7.1 ounces (including the cover). Interestingly, the TI-Nspire™ CX CAS model is a more powerful calculator and is allowed on the calculator portion of the SAT®.
The SAT® has Two Math Sections: No Calculator Section (20 questions) and Calculator Section (38 questions)
If you haven’t seen the SAT® since it was redesigned in the spring of 2016, you may not have realized that for about one-third of the math portion of the SAT® a calculator of any kind is prohibited. I think this is why they allow CAS calculators on approximately two-thirds of the test. The College Board knows that students need to be able to do mathematics with and without a calculator if they want to have the highest scores.
