Calculator rules on exam day
One approved calculator goes into the testing room, without its cover. Spare calculators and covers stay with your things outside. A TI-30XS is also available on screen during the exam.
Which is the best calculator for the PE exam?
NCEES doesn’t rank or recommend models; any one on the list is allowed. Since only that list goes in, practice with the model you’ll bring, so you aren’t learning its buttons on the day.
