CAS allows calculators to solve algebra problems symbolically (e.g., solve for x). Models like the TI-89, TI-Nspire CAS, and HP Prime have this feature and are banned.
Calculators with typewriter-like keyboards are prohibited.
Proctors may check your calculator. All programs and documents must be removed, especially those that add CAS functionality.

What is the ACT Calculator Policy?
The official ACT calculator policy is designed to ensure fairness and test security. The core question for students is often, “is a ti 84 calculator allowed on the act?” The short answer is yes, most TI-84 models are allowed. However, the policy is nuanced. Generally, the ACT permits any 4-function, scientific, or graphing calculator, provided it is not on the specific prohibited list and does not have forbidden features.
The policy’s primary goal is to prevent students from using devices that offer an unfair advantage. Prohibited features include Computer Algebra Systems (CAS), QWERTY keyboards, and wireless communication capabilities. Knowing whether your specific calculator, like a TI-84 Plus CE, meets these guidelines is crucial for a smooth test day experience. This guide and our eligibility checker are designed to clarify if a TI 84 calculator is allowed on the ACT and demystify the rules for other models.
ACT Calculator Policy Explained
Understanding the specific rules is the best way to determine if your calculator is compliant. The ACT explicitly prohibits certain models and features. The fundamental rule is that calculators with Computer Algebra Systems (CAS) are banned. A CAS can perform symbolic manipulation (like solving for ‘x’ algebraically), which is considered an unfair advantage. This is why models like the TI-89 and TI-Nspire CAS are prohibited, while their non-CAS counterparts (like the standard TI-Nspire) are allowed.
| Feature / Rule | Status | Explanation |
|---|---|---|
| Standard Graphing (e.g., TI-84 Plus, TI-83) | Allowed | These models are the standard and are explicitly permitted. |
| Computer Algebra System (CAS) | Prohibited | Any calculator with CAS is banned. This includes the TI-89, TI-92, and HP Prime. |
| QWERTY Keyboard | Prohibited | Calculators with typewriter-style keyboards are not allowed. |
| Programs and Apps | Allowed (with conditions) | Programs must be removed if they provide CAS functionality. Proctors may inspect your device. |
| Wireless Communication / Internet | Prohibited | No devices that can communicate with other devices are allowed. This includes phones and smartwatches. |
| Makes Noise or Needs Power Outlet | Allowed (with modifications) | The sound must be muted, and calculators cannot be plugged into an outlet during the test. |
Practical Examples (Real-World Use Cases)
Example 1: The Compliant Student
A student has a TI-84 Plus CE. Before the test, they ensure no games or unauthorized programs are installed. They select “TI-84 Plus CE” in the calculator, and leave the “CAS,” “QWERTY,” and “Prohibited Apps” boxes unchecked. The result is “Allowed.” The student can confidently bring their calculator, knowing it meets the official ACT policy. This is the most common and recommended scenario, as using a familiar tool is a key advantage.
Example 2: The Prohibited Calculator
Another student has a TI-89 Titanium. This is a powerful calculator, but it comes with a built-in Computer Algebra System (CAS). When they select “TI-89” in the checker, the result is immediately “Not Allowed.” Even if they don’t know what CAS is, the model itself is on the prohibited list. This saves the student from being dismissed from the testing room or having their test voided. The correct action is to acquire a permitted model, like a TI-84 Plus, for the exam.
How to Use This ACT Calculator Eligibility Checker
This tool simplifies the process of checking if your calculator is permitted. Follow these steps to ensure you get an accurate result regarding the question, “is a ti 84 calculator allowed on the act?”
- Select Your Model: Start by choosing your calculator model from the dropdown list. We’ve included popular allowed and prohibited models for quick checking. If your model isn’t listed, choose “Other/Unsure.”
- Identify Key Features: Answer the “Yes/No” questions. Check the box if your calculator has a CAS, a QWERTY keyboard, or prohibited apps. If you’re unsure if your calculator has CAS, a quick search for “[Your Model] + CAS” will usually provide an answer.
- Review the Result: The tool will instantly provide a primary result: “Allowed,” “Not Allowed,” or “Allowed with Conditions.” The intermediate results will explain *why* this decision was reached, referencing the specific rules your selections triggered.
- Analyze the Compliance Score: The bar chart gives a visual representation. A full green bar indicates full compliance, while any red indicates a prohibited feature.
- Reset or Copy: Use the “Reset” button to start over or the “Copy Results” button to save the information for your records.
Key Factors That Affect if a TI-84 is Allowed on the ACT
While the TI-84 series is generally safe, several factors can affect its eligibility. Understanding these is vital for anyone asking, “is a ti 84 calculator allowed on the act?“
- Model Version: All versions of the TI-84 Plus are allowed, including the TI-84 Plus CE. This is a key starting point for determining eligibility.
- Presence of CAS: The single most important factor. The standard TI-84 does not have CAS. However, programs can be downloaded that add this functionality. If such a program is on your calculator, it becomes prohibited.
- Installed Programs/Apps: The ACT forbids programs and applications that add prohibited functionality. This includes CAS apps, games, and stored notes or documents. Test proctors have the right to inspect and clear your calculator’s memory.
- Physical Condition: While rare, a calculator that has been modified to include a QWERTY keyboard or any communication device would be banned.
- Power Source: Your calculator must be battery-operated. You cannot plug it into a wall outlet during the exam. Ensure you have fresh batteries or a full charge.
- Proctor Discretion: Ultimately, the test day proctor has the final say. Having a calculator that is clearly compliant and free of suspicious apps (like a standard TI-84 Plus CE) avoids any potential issues.
Frequently Asked Questions (FAQ)
- 1. Is the TI-84 Plus CE allowed on the ACT?
- Yes, the TI-84 Plus CE is explicitly allowed on the ACT math section, provided it does not have any prohibited programs installed.
- 2. What’s the main difference between an allowed TI-84 and a prohibited TI-89?
- The main difference is that the TI-89 has a built-in Computer Algebra System (CAS), which can solve equations symbolically. The TI-84 does not have CAS and is therefore permitted.
- 3. Do I need to clear the memory on my TI-84 before the test?
- The ACT requires you to remove any programs that have CAS functionality. While not strictly required to clear everything, the safest approach is to back up your data and clear all programs and apps to avoid any issues with the proctor.
- 4. Can I use a calculator on all sections of the ACT?
- No, calculators are only permitted on the Mathematics section of the ACT.
- 5. What if my calculator is not on the list?
- If your calculator is not on the prohibited list and does not have any forbidden features (like CAS or a QWERTY keyboard), it is likely allowed. Use our checker’s feature-based questions to confirm.
- 6. Is a scientific calculator enough for the ACT?
- Yes, all problems on the ACT can be solved without a calculator. A scientific calculator is sufficient, but a graphing calculator like the TI-84 can be more efficient for certain problems involving functions and graphs.
- 7. Are phone calculator apps allowed?
- No, calculator apps on cell phones, tablets, or any other smart device are strictly prohibited.
- 8. Can I share my calculator with another student?
- No, sharing calculators during the test is not permitted and could lead to dismissal.
