1. ACT Calculator Policy Overview

The ACT allows calculators only on the mathematics test. While calculators can be helpful, all problems can be solved without one. The test is designed to measure mathematical reasoning ability, not just computational skill.

2. Permitted Calculator Types

Allowed Calculators Include:

• Four-function calculators (basic arithmetic)
• Scientific calculators (logarithms, trigonometry)
• Graphing calculators (e.g., TI-83, TI-84, TI-Nspire CX)
• Calculators on permitted devices (with prior approval)

3. Prohibited Calculators

Prohibited Calculators Include:

• Calculators with built-in computer algebra systems (e.g., TI-89, TI-92)
• Calculators with QWERTY keyboards
• Calculators with paper tape or printers
• Calculators that make noise or require an electrical outlet
• Calculator apps on phones, tablets, or laptops

4. Calculator Recommendations

Tips for Calculator Use:

• Bring a calculator you're familiar with
• Have fresh batteries or bring spares
• Practice with your calculator before test day
• Remember that not all problems require a calculator

5. Frequently Asked Questions (FAQ)

Q1: Is a calculator required for the ACT?
A: No, but it's recommended for the math section. All problems can be solved without one.

Q2: Can I use a TI-84 calculator on the ACT?
A: Yes, the TI-84 series is permitted.

Q3: Are CAS calculators allowed?
A: No, calculators with computer algebra systems (CAS) like TI-89 are prohibited.

Q4: Can I use my phone's calculator?
A: No, all electronic devices including phones must be turned off during testing.

Q5: Should I bring a backup calculator?
A: It's not required but could be helpful in case of battery failure.
