Calculators
You will be allowed to use a calculator while working on the CHSPE Mathematics section. All problems can be solved without the use
of a calculator. If you wish to use a calculator, however, you may bring a solar- or battery-powered basic, non-statistical, nonscientific,
non-programmable calculator. A basic calculator has 25 or fewer buttons and can perform no more than the four standard
mathematical functions of addition (+), subtraction (-), multiplication (x), and division () and, possibly, percentage (%), square root (√),
and sign change (+/-). The calculator may have a simple memory (M+, M-, MC, MR).
Test administration staff will NOT provide calculators or batteries and will make sure
that your calculator is acceptable before admitting you to the testing room. You
may bring a backup calculator. You may only use one calculator at a time. If you
bring a backup calculator or extra batteries, they must be put away. If you need to
use any of your backup equipment, raise your hand. Th e calculator must not be in
a case or sleeve of any kind, and you may not bring a calculator manual. You may
not share your calculator with any other examinee. You may not use your calculator
to share information during the test or to remove test questions or answers from
the test room. If you leave the test room before you have completed testing (e.g.,
to use the restroom), your calculator(s) must remain on your desk in plain sight.
Download the Calculator Guide (PDF) for example pictures of acceptable and unacceptable calculators.
Unacceptable calculators for CHSPE include:
- Statistical calculators.Statistical calculators typically have buttons with "∑" on them or buttons for statistical computation menus
usually labeled "STAT" or "STO." Statistical calculators also commonly have statistical buttons such as "Sx," "Sy," or "Sx2 ."
- Scientific calculators. These are easily identified because of their sin, cos, and tan buttons. Other buttons unique to scientific
calculators are "log" and "π" (pi).
- Programmable calculators. These have menus and blank buttons that can be used for varying functions. They often also have an
alphabetic (QWERTY) keypad. Any calculator that has the capability of entering letters along with numbers is unacceptable.
- Calculators that are able to print.
- Calculators that make noise that cannot be silenced.
- Calculators that must be plugged into an outlet.
- Calculators that are part of other devices (e.g., watches, PDAs, cellular phones).
- Calculators that have raised screens that may be seen by other examinees.
