PSAT Calculator Policy Checker
A quick tool to check if your calculator is allowed for the PSAT/NMSQT exam.
Is Your Calculator Approved?
Enter the model name to see if it’s on the allowed or prohibited list.
Policy Breakdown:
- General Rule: Most graphing, scientific, and four-function calculators are allowed.
- Primary Prohibition: Calculators with Computer Algebra System (CAS) functionality are NOT allowed.
- Built-in Option: The digital test has an embedded Desmos calculator you can use.
Understanding What Calculators Are Allowed on the PSAT
Knowing what calculators are allowed on the PSAT is crucial for test day success. The College Board, which administers the PSAT/NMSQT, has specific rules to ensure fairness. While you can take the entire math section with the built-in digital calculator, many students prefer using a physical calculator they are familiar with. This guide and checker will help you determine if your device is compliant with the official PSAT calculator policy.
PSAT Calculator Rule Breakdown
The “formula” for determining if a calculator is allowed isn’t mathematical, but rather a set of rules. The most significant rule is the prohibition of calculators with a Computer Algebra System (CAS). CAS functionality can symbolically solve algebraic equations, which gives an unfair advantage. Here is a breakdown of allowed and prohibited features.
| Feature / Type | Status | Explanation |
|---|---|---|
| Graphing Capability | Allowed | Most graphing calculators are permitted, as long as they don’t have CAS. |
| Scientific Calculator | Allowed | All scientific calculators are acceptable. |
| Four-Function Calculator | Allowed | Basic calculators are allowed but not recommended due to limited functionality. |
| Computer Algebra System (CAS) | Prohibited | Calculators that can manipulate symbolic expressions (e.g., factor, expand) are banned. |
| QWERTY Keyboard | Prohibited | Calculators with typewriter-like keyboards are not allowed. |
| Stylus / Pen-Input | Prohibited | Devices requiring a stylus are not permitted. |
| Wireless Communication | Prohibited | Calculators with Wi-Fi, Bluetooth, or cellular access are strictly forbidden. |
| Needs External Power | Prohibited | Only battery-operated calculators are allowed. |
Practical Examples of Calculator Models
Let’s look at some real-world examples to clarify the rules.
Example 1: A Common Approved Calculator
- Input Model: TI-84 Plus CE
- Analysis: This is a very popular graphing calculator. It does not have a “CAS” designation in its name. It is listed as an approved calculator.
- Result: Allowed
Example 2: A Common Prohibited Calculator
- Input Model: TI-Nspire CX II CAS
- Analysis: The “CAS” in the model name explicitly indicates it has a Computer Algebra System. The College Board’s list of prohibited calculators includes all models with “CAS” in the name.
- Result: Prohibited
How to Use This PSAT Calculator Checker
- Locate Your Calculator’s Model Name: This is usually printed on the top of the calculator.
- Enter the Model Name: Type the full model name into the input field above.
- Click “Check Status”: The tool will compare your input against lists of known allowed and prohibited models and features.
- Interpret the Result:
- ALLOWED: Your calculator is very likely compliant.
- PROHIBITED: Your calculator is on the banned list and you should not bring it.
- CHECK MANUALLY: The model is not in our database. You must check it against the feature rules (especially for CAS functionality). When in doubt, consult the official College Board PSAT calculator policy.
Key Factors That Affect the PSAT Calculator Policy
- CAS Functionality: This is the single most important factor. If your calculator has CAS, it is not allowed.
- Official Lists: The College Board provides lists of specifically prohibited calculators. If your model is on that list, it’s banned.
- Physical Features: Features like QWERTY keyboards, styluses, or anything that makes noise or prints to paper tape will disqualify a calculator.
- Connectivity: Any device that can connect to the internet or other devices is prohibited.
- Power Source: Calculators that need to be plugged into an electrical outlet are not allowed.
- Test Center Discretion: Proctors have the final say. A calculator with a very large or raised display might lead to you being reseated.
Frequently Asked Questions (FAQ)
If your calculator isn’t on an official list, you must verify it yourself. Ensure it does not have a CAS, a QWERTY keyboard, or any other prohibited feature. Most standard scientific calculators are fine.
Yes, most graphing calculators are allowed, provided they do not have CAS functionality. Popular models like the TI-84 series are widely used.
A CAS is a sophisticated program that can perform symbolic math, like simplifying `(x+y)^2` into `x^2+2xy+y^2` or solving equations for variables instead of just numbers. This is a banned feature.
No. Phones, tablets, smartwatches, and laptops are strictly prohibited. You must use a standalone, approved calculator or the one built into the testing app.
No, it’s not required. All math questions can be solved without one, and the digital testing platform (Bluebook) has an embedded Desmos calculator. However, it’s recommended to bring a familiar, approved model.
The TI-Nspire CX is allowed. The TI-Nspire CX CAS is prohibited. The “CAS” in the name is the key difference, indicating it has the banned Computer Algebra System.
Bring a calculator you are familiar with, ensure it has fresh batteries, and know how to use its functions. You are not allowed to share calculators.
The most up-to-date rules are always on the College Board website. You can find the official PSAT calculator policy there.
