Ultimate Guide to SAT Test Acceptable Calculators
The College Board maintains a strict policy regarding which calculators are permitted for the SAT Suite of Assessments. Choosing the right device isn't just about following rules—it's about maximizing your efficiency on the Math section, particularly for complex functions and data analysis.
What Calculators are Allowed on the SAT?
Most graphing calculators and all scientific calculators are permitted. However, devices with internet access, cameras, QWERTY keyboards, or those requiring a power outlet are strictly prohibited. Below are the most popular approved models:
- Texas Instruments: TI-83, TI-84 Plus, TI-84 Plus CE, TI-Nspire CX, TI-Nspire CX II CAS.
- Casio: FX-9750GII, FX-9860GII, Graph 35+, FX-CG50 (PRIZM).
- HP: HP 39gII, HP 48 series, HP Prime.
Scientific vs. Graphing: Which is Better?
While a scientific calculator can handle basic arithmetic, trigonometry, and logarithms, a graphing calculator is highly recommended for the SAT. Graphing calculators allow you to visualize parabolas, find intersections, and solve systems of equations much faster than manual methods. This can save you an average of 15-20 seconds per question on the calculator-active section.
Important Calculator Rules
- No Sharing: You cannot share a calculator with another student during the test.
- Check Batteries: Ensure your calculator is fully charged or has fresh batteries. No chargers are allowed in the testing room.
- Bring Your Own: Some testing centers do not provide calculators. If you don't bring one, you may have to take the test without it.
Calculator Tips for Test Day
Don't wait until the day before the test to buy a new calculator. Familiarity is key. You should know how to use the "Intersect" function, "Table" function, and "Solver" features on your specific model. Remember, the calculator is a tool to supplement your math skills, not replace them.
