Yes, you can use a calculator on the HiSET, but only during the Mathematics section,and only the on-screen TI-30XS scientific calculator provided by the test system. You cannot bring your own calculator, even if it’s approved for other exams.
The calculator on the HiSET is built into the testing software and is available for all math questions except the first few in some test versions. You’ll see it as a button on the screen during the 90-minute Mathematics test. It supports basic operations, square roots, exponents, and fractions,enough for high school–level problems.
How the Calculator Works on the HiSET
The calculator on the HiSET is identical to the physical TI-30XS model. To use it effectively, practice with the free version on the official HiSET website before test day. Many test takers lose time or make errors because they’re unfamiliar with its layout.
You do not need the calculator for every question. Some problems are faster to solve mentally or by hand. Use the calculator on the HiSET for multi-step calculations, decimals, or square roots,but not for simple arithmetic.
The calculator is not available for any other subject:
- Language Arts
- Science
- Social Studies
- Essay
These sections require only reading, writing, and reasoning skills.
Why This Matters
The HiSET is designed to test your ability to apply math,not just use a tool. The calculator helps reduce computation errors, but you still need to understand when and how to set up problems correctly.
To prepare:
- Take the official HiSET practice test at hiset.ets.org
- Use the online TI-30XS calculator during practice
- Time yourself to build confidence under pressure
Knowing when to use the calculator on the HiSET is as important as knowing how to use it. It’s a tool for accuracy,not a shortcut to understanding.
Master it, and you’ll save time and avoid avoidable mistakes.
