What calculator is allowed on the GED?
One model, the TI-30XS MultiView. The test gives you an on-screen version; at a test center you can bring the real one. Here's exactly how it works and why most people buy the handheld.
The short answer
Calculator rules can change. GED.com publishes the current calculator policy and a free reference sheet; check it for your state and whether you're testing at a center or online.
Why buy the handheld if the test gives you one on screen
Clicking calculator keys with a mouse under a clock is slow, and the TI-30XS has a few keys that behave differently from a phone calculator: fractions, the answer-toggle key, and negative numbers. Students who practice on the physical one for a few weeks stop thinking about the calculator on test day. It's also allowed on the ACT, SAT and most state tests, so it outlives the GED.
