Calculator Policy
You may use a calculator on
the ACT Mathematics Test but not on any of the other tests in the ACT. You are
not required to use a calculator. All problems on the Mathematics Test can be
solved without a calculator.
WARNING: You are responsible for
knowing if your calculator is permitted. If you use a prohibited calculator, or
you use a calculator on any test other than the Mathematics Test, you will be
dismissed and your answer document will not be scored. If scores are reported
and ACT determines that you used a prohibited calculator or used one
inappropriately on that test, those scores may be cancelled.
If you wish to use a
calculator, you are responsible for bringing it to the test center and making
sure it works properly. The test center will not provide backup calculators or
batteries. You may not share a calculator with anyone else. You may bring a
backup calculator, but you may not have more than one on your desk or in
operation at a time.
You may use your calculator
only while you are working on the Mathematics Test. At all other times, it must
be turned off and put away. If you finish the Mathematics Test before time is
called, you must turn your calculator off and wait quietly. If your calculator
has games or other functions, you may not use those functionsyou may use only
the mathematics functions of your calculator.
