When a disability impacts a student’s ability to perform mathematic calculations, he or she may request permission to use a four-function calculator for math sections that do not permit the use of a calculator.

Limitations on Four-Function Calculator Use

The use of a four-function calculator is limited as follows:

  • Graphing calculators may not be used. Only calculators that are limited to performing addition, subtraction, multiplication, and division, square-root and percent may be used.​
  • Calculators must comply with the College Board calculator use policy. Learn about calculator policies for the PSAT/NMSQT and PSAT 10 and the SAT. Visit AP Students to see calculator policies for specific AP Exams.
  • Four-function calculators can only be used on test sections that require math calculations. They must be put away during non-math sections.

Eligibility for Four-Function Calculator Use

Students allowed to use a calculator to take school tests are not necessarily eligible for a calculator accommodation on College Board assessments because College Board assessments can differ from classroom tests. The four-function calculator accommodation must be approved for SSD, and is appropriate for students who have a disability that impacts their ability to perform mathematic calculations; for example, a student diagnosed with specific learning disorder with impairment in mathematics, or dyscalculia.
