SAT Calculator Checker

Official 2026 update: Check if your model is Approved or Prohibited under the new CAS ban.

Policy Update: August 2025

The 2026 CAS Ban

College Board has updated the calculator policy for the Digital SAT. All calculators with CAS (Computer Algebra System) functionality are now strictly prohibited.

College Board Calculator Policy Update (2025-2026)

The move to the Digital SAT (DSAT) has brought significant changes to what hardware students can bring into the testing room. While the Bluebook app provides a built-in Desmos graphing calculator, many students prefer the tactile feel of a handheld device like a TI-84 or TI-Nspire.

What is Allowed?

  • Most graphing calculators without CAS.
  • Scientific calculators (all standard models).
  • Four-function calculators (though not recommended).
  • The built-in Desmos calculator in Bluebook.

What is Banned?

  • CAS (Computer Algebra System) models.
  • Calculators with QWERTY keyboards (e.g., TI-92).
  • Models that require a power cord or have wireless.
  • Stylus-based or touchscreen calculators.

Is the TI-Nspire allowed on the SAT?

This is the most common question. Yes and No. The TI-Nspire CX and CX II (Non-CAS) are fully allowed. However, the TI-Nspire CX CAS and CX II CAS are strictly prohibited for the 2026 SAT cycle. Always check the top-right corner of your calculator for the "CAS" label before test day.
