ACT Calculator Policy Logic and Decision Criteria
The ACT’s stance on calculator usage isn’t based on the brand or general type (scientific vs. graphing) alone, but rather on the presence of specific features that could compromise test security or provide an unfair advantage. Understanding this underlying logic is key to navigating the ACT calculator rules.
Step-by-Step Policy Derivation:
- Initial Assumption: Most standard scientific and graphing calculators are generally permitted for the ACT Math and Science sections.
- Feature Scan: The calculator is then evaluated for a list of explicitly prohibited features.
- Prohibition Check: If *any* of these prohibited features are detected, the calculator is immediately deemed “Not Allowed.”
- Final Determination: If no prohibited features are found, the calculator is “Allowed.”
This straightforward logic means that even a basic scientific calculator could be disallowed if it somehow possessed a prohibited feature (though this is rare), and an advanced graphing calculator could be allowed if it lacked all prohibited features.
