What is the “Are You Allowed to Use a Calculator on the PSAT” Policy?

The question of whether you are allowed to use a calculator on the PSAT is crucial for test-day readiness. The simple answer is yes, but with important specifics. As of the transition to the digital PSAT format, an acceptable calculator is permitted on the entire Math section. This marks a change from the old paper-based test, which had a dedicated “No-Calculator” portion. Now, both modules of the digital PSAT Math section allow calculator use. However, you are strictly not allowed to use a calculator during the Reading and Writing section. Understanding this policy is the first step in building a solid test-day strategy. Many students wonder if they need a physical calculator, and the answer is no, not necessarily. The digital test, delivered on the Bluebook™ application, includes a powerful built-in graphing calculator (Desmos) that is available for every math question.

A common misconception is that any calculator is fine. This is incorrect. The College Board has a strict list of approved and prohibited devices. Prohibited calculators include those with computer-algebra system (CAS) functionality, QWERTY keyboards, internet access, or those that make noise. Therefore, checking if your personal device is on the approved list is a critical part of preparing for the test. The policy is designed to ensure fairness and prevent any student from having an unfair advantage through technology. Answering the question “are you allowed to use a calculator on the PSAT” requires knowing the rules for your specific device and the section you’re on.

PSAT Calculator Rules and Mathematical Explanation

The rules governing calculator use on the PSAT are not based on a mathematical formula but on a set of policies by the College Board. The core principle is that a calculator is a tool to aid in problem-solving, not to provide an unfair advantage. The digital PSAT allows calculator use across the entire Math section, which consists of two modules. This policy streamlines the process, as students no longer need to switch between calculator and no-calculator mindsets. The built-in Desmos calculator is a key feature, offering both scientific and graphing capabilities. This ensures every student has access to a powerful tool, leveling the playing field. Students can also bring their own approved calculator if they prefer. Familiarity with your chosen calculator—whether it’s the embedded Desmos or your own handheld device—is far more important than its price or number of functions.

Practical Examples (Real-World Use Cases)

Example 1: Student with a TI-89 Calculator

A student arrives on test day with a Texas Instruments TI-89 Titanium calculator, a device they have used throughout their high school math classes. During the check-in process, the proctor inspects the calculator. The TI-89 is a powerful device, but it includes a Computer Algebra System (CAS). According to College Board policy, calculators with CAS functionality are explicitly prohibited. The student would be informed that they cannot use this calculator. They would then have two options: proceed using only the built-in Desmos calculator provided in the Bluebook software or use a backup, non-CAS calculator if they brought one. This scenario highlights why it’s critical to check the official list of banned calculators before test day.

Example 2: Student During the Reading & Writing Section

A student has just completed the two Math modules and is now starting the Reading and Writing section. Their personal graphing calculator is still on their desk. The test proctor would instruct the student to put the calculator away completely, likely under their desk. Using or even having a calculator accessible during the non-math portions of the exam is a violation of testing rules and could lead to dismissal and score cancellation. This example underscores that the answer to “are you allowed to use a calculator on the PSAT” is highly dependent on which section of the test is active.

Key Factors That Affect PSAT Calculator Rules

The rules aren’t arbitrary; several factors influence the policy on whether you are allowed to use a calculator on the PSAT. Understanding these can improve your test strategy.

• Test Format (Digital vs. Paper): The move to a digital format is the single biggest factor. It enabled the integration of a universal, high-quality graphing calculator (Desmos), ensuring equity.
• Section Content: The Math section is designed to test problem-solving and reasoning, where a calculator is a relevant tool. The Reading and Writing section tests literacy and language skills, where a calculator offers no benefit and is thus prohibited.
• Test Security and Fairness: The prohibition of calculators with internet, communication features, or QWERTY keyboards is a security measure to prevent cheating. Banning CAS ensures the test assesses a student’s mathematical reasoning, not the calculator’s ability to solve equations symbolically.
• Calculator Familiarity: The policy allowing students to bring their own approved device acknowledges that many are most comfortable and efficient with the calculator they’ve used for years. For help with your study plan, consider our study planner tool.
• Battery and Power: Rules requiring battery power and banning power cords are practical; they prevent logistical issues with outlets and ensure the test environment is safe and orderly.
• Advancements in Technology: The College Board regularly reviews its policies to adapt to new technology. The ban on certain CAS models and the adoption of Desmos reflect this ongoing evaluation.
