Preparing Calculators for WESTEST 2

Use of calculators on WESTEST 2 is permitted on all sessions of the Mathematics and Science tests for all grade levels. Tests may be given by grade level on different days to allow more equitable access to calculators. 

 A calculator is not required.

  • All the questions can be solved without a calculator.
  • If a student regularly uses a calculator in mathematics and science work, he or she may wish to use the same or similar one as he or she takes the WESTEST 2 Mathematics and Science tests.
  • It is recommended students use calculators they have experience using; a more powerful but unfamiliar calculator is not likely to give an advantage over using a calculator they are familiar with.
  • Any calculator used on WESTEST 2 must not be on the prohibited list and must be prepared for testing.

 Any four-function, scientific, or graphing calculator may be used, unless it has features described as prohibited.  For models permitted with modification, the examiner will be required to modify some of the calculator's features.

 Prohibited Calculators

The following types of calculators are prohibited

    • Texas Instruments: All model numbers beginning with TI-89 or TI-92 and the TI-Nspire CAS (TI-Nspire non CAS is permitted)
    • Hewlett-Packard: HP 48GII and all models that begin with HP 40G, HP 49G, or HP 50G
    • Casio: Algebra fx 2.0, ClassPad 300, ClassPad 330, and all model numbers that begin with CFX-9970G
  • pocket organizers
  • hand-held or laptop computers including PDAs
  • electronic writing pads or pen-input devices (Sharp EL9600 is permitted)
  • calculators built into cellular phones or other electronic communication devices
  • calculators with a typewriter keypad (keys in QWERTY format)--Calculators with letter keys not in QWERTY format are permitted.
  • any other electronic device that has not been approved

Calculators Permitted with Modification

  • calculators with paper tape  (remove the paper tape)
  • calculators that make noise  (turn off the sound)
  • calculators that can communicate with other calculators
    • wirelessly  ( completely cover the wireless data port with heavy opaque material, such as duct or electrician's tape)
    • wired (students are not to have access to  linking cables/cords during testing)
  • calculators that have power cords (remove all power/electrical cords)

Students may use a calculator provided by the school or a personal calculator that meets the above listed criteria. Students will not be permitted to share calculators during testing.

If a graphing calculator is not on the prohibited list, make sure the calculator is either:

  • in Press to Test mode,
  • running TestGuard so all APPS and PRGMs are either disabled or deleted, or
  • cleared of anything in the memory.   All types of memory, including standard memory, ROM and flash ROM must be cleared to factory default both before and after testing.  Do not store test items/materials in your calculator's memory.  There is not a memory issue if the student is using a 4-function or scientific calculator.
