What is the GRE Calculator Policy?
The GRE Calculator Policy dictates which types of calculators are permitted during the Graduate Record Examinations General Test. This policy is in place to ensure fairness and to test candidates’ quantitative reasoning skills under specific conditions. Understanding these rules is essential for test-takers to avoid any complications on test day. The policy primarily focuses on preventing the use of devices that offer advanced functionalities beyond basic mathematical operations, which could provide an unfair advantage.
Who Should Use This Information:
- Anyone planning to take the GRE General Test.
- Test-takers who are unsure about bringing their own calculator.
- Individuals who want to understand the capabilities of the on-screen GRE calculator.
Common Misconceptions:
- Misconception: “All scientific calculators are allowed.” Reality: While the GRE calculator has scientific functions, many complex scientific calculators with advanced features (like graphing or programming) are prohibited.
- Misconception: “I can use my smartphone’s calculator app.” Reality: Smartphones and tablets are generally prohibited in the testing center, and thus their calculator apps cannot be used.
- Misconception: “The GRE provides a very basic calculator.” Reality: The on-screen GRE calculator offers more than just basic arithmetic; it includes functions like square root, exponents, and percentages, similar to a standard scientific calculator.
GRE Calculator Policy Logic and Explanation
The core logic behind the GRE calculator policy is to allow a calculator that provides necessary tools for quantitative problem-solving without automating the entire reasoning process. The official GRE calculator, which is available on-screen during the test, includes several functions. Our calculator helps determine if a *personal* calculator aligns with these allowed functions.
The GRE policy essentially allows calculators that perform basic arithmetic, square roots, percentages, and exponents, but prohibits calculators that are programmable, have QWERTY keyboards, or have features that emulate the on-screen calculator’s full capabilities. Handheld devices like smartphones are strictly forbidden.
Policy Determination Logic:
A personal calculator is deemed permissible if it meets the following criteria:
- It is not a graphing, programmable, or electronic handwriting recognition device.
- It does not have a QWERTY keyboard.
- It does not have any other features that emulate the on-screen GRE calculator (e.g., advanced statistical functions, integration/differentiation, extensive memory recall beyond simple RPN).
- It is not a handheld device like a smartphone or tablet.
Essentially, a standard scientific calculator is often borderline. If it has complex functions beyond what the on-screen calculator offers, it might be disallowed. The most reliable approach is to rely on the on-screen calculator provided.
Variable Definitions for Policy Check:
| Variable | Meaning | Unit | Typical Range / Value |
|---|---|---|---|
| Calculator Type | The general category of the calculator (Basic, Scientific, etc.) | Category | Basic, Scientific, Graphing, Programmable, Phone |
| Square Root (√) | Presence of square root functionality | Boolean | Yes / No |
| Percentage (%) | Presence of percentage calculation functionality | Boolean | Yes / No |
| Exponents (x^y) | Presence of exponentiation functionality | Boolean | Yes / No |
| Logarithms (log, ln) | Presence of logarithmic function(s) | Boolean | Yes / No |
| Is Programmable | Ability to store and run user-defined programs | Boolean | Yes / No |
| Is Handheld Device | Is the device a smartphone, tablet, or similar | Boolean | Yes / No |
Practical Examples of GRE Calculator Policy
Let’s look at a few scenarios to illustrate the GRE calculator policy.
Example 1: Standard Scientific Calculator
Scenario: A test-taker wants to bring a Casio fx-991EX Classwiz scientific calculator.
Input Analysis:
- Calculator Type: Scientific
- Square Root (√): Yes
- Percentage (%): Yes
- Exponents (x^y): Yes
- Logarithms (log, ln): Yes
- Is Programmable: No
- Is Handheld Device: No
Calculator Result: Likely Not Allowed (Borderline)
Interpretation: While this calculator has many functions similar to the on-screen GRE calculator (√, %, exponents), it also has advanced logarithmic functions and potentially other features (like complex number calculations or equation solvers) that ETS might deem too advanced or capable of emulating the on-screen calculator’s full scope. ETS explicitly prohibits calculators with advanced scientific functions that go significantly beyond basic computation. Relying on the on-screen calculator is the safest bet.
Example 2: Basic Four-Function Calculator
Scenario: A test-taker brings a simple calculator that only performs addition, subtraction, multiplication, and division.
Input Analysis:
- Calculator Type: Basic
- Square Root (√): No
- Percentage (%): No
- Exponents (x^y): No
- Logarithms (log, ln): No
- Is Programmable: No
- Is Handheld Device: No
Calculator Result: Allowed
Interpretation: This type of calculator is basic enough that it would certainly be permitted. However, it lacks essential functions like square roots and percentages that are available on the GRE’s on-screen calculator and often useful for quantitative problems. While allowed, it’s not ideal.
Example 3: Smartphone Calculator App
Scenario: A test-taker tries to use the calculator app on their iPhone.
Input Analysis:
- Calculator Type: Smartphone/Tablet Calculator App
- Square Root (√): Yes
- Percentage (%): Yes
- Exponents (x^y): Yes
- Logarithms (log, ln): Yes
- Is Programmable: No (typically)
- Is Handheld Device: Yes
Calculator Result: Prohibited
Interpretation: Smartphones, tablets, and similar devices are strictly prohibited in the GRE testing center, regardless of the calculator app’s functionality. Test-takers must put these devices away before the test begins.

Key Factors Affecting GRE Calculator Policy Decisions
Several factors determine whether a calculator is allowed on the GRE. ETS (Educational Testing Service) has specific rules to maintain test integrity and ensure candidates rely on their reasoning skills rather than computational shortcuts.
- Functionality Complexity: The GRE allows basic arithmetic, square roots, percentages, and exponents. Calculators with advanced statistical functions, calculus capabilities (derivatives, integrals), or complex equation solvers are typically prohibited because they go beyond the scope of what the on-screen GRE calculator offers and could provide an unfair advantage.
- Programmability: Any calculator that allows users to store and run custom programs or formulas is strictly forbidden. This prevents test-takers from pre-loading answers or complex calculation shortcuts.
- Device Type: Handheld electronic devices, including smartphones, tablets, smartwatches, and any device with a QWERTY keyboard or communication capabilities, are not allowed in the testing room. Only specific, approved models of basic or scientific calculators are permitted if the test center allows personal calculators.
- Emulation of On-Screen Calculator: Calculators that can perfectly mimic or significantly surpass the functionality of the GRE’s built-in on-screen calculator are generally disallowed. The goal is to standardize the tools available.
- Power Source: While not a primary restriction for allowed types, extremely high-powered devices or those with unusual power sources might raise flags. Standard battery-powered calculators are expected.
- Test Center Discretion: Ultimately, the test center administrators have the final say. Even if a calculator seems to meet the criteria, they can disallow it if they deem it inappropriate or disruptive. It’s always best to err on the side of caution and rely on the provided on-screen calculator.
- Test Version: While less common, policies can sometimes vary slightly for different GRE test formats or special administrations. Always check the official ETS website for the most current and specific information relevant to your test date and location.
