What is the use of calculators in IB DP examinations 2025?
The International Baccalaureate (IB) has a strict policy regarding the use of calculators in Diploma Programme (DP) examinations to ensure fairness and prevent academic misconduct. The policy for 2025 specifies which types of calculators are permitted, required, or prohibited for each subject. The core idea is to allow tools that aid in calculation without giving students access to stored information or unfair advantages. A key distinction is made between standard scientific calculators, Graphic Display Calculators (GDCs), and those with Computer Algebra Systems (CAS). While some subjects require a GDC, features like CAS, wireless communication, and QWERTY keyboards are heavily restricted or outright banned.
The ‘use of calculators in ib dp examinations 2025’ Formula and Explanation
The “formula” for determining if a calculator is allowed is not a mathematical equation, but a logical decision tree based on IB regulations. This calculator automates that process. The logic checks your inputs against the rules for your selected subject.
The primary variables are:
| Variable | Meaning | Unit (Inferred) | Typical Range |
|---|---|---|---|
| Subject Group | The IB academic category of your exam. | Categorical | Groups 1-6 |
| GDC Capability | Ability to plot graphs. | Boolean (Yes/No) | Required for Maths/Sciences |
| CAS Functionality | Ability to manipulate algebraic expressions. | Boolean (Yes/No) | Prohibited unless disabled |
| Prohibited Features | Includes Wi-Fi, QWERTY keyboards, mains power. | Boolean (Yes/No) | Always prohibited |
For more details, you might review the IB’s official calculator policy document.
Practical Examples
Example 1: Math HL Student
- Inputs: Subject = Mathematics, GDC = Yes, CAS = Yes, Other Prohibited = No.
- Logic: The calculator is a GDC, which is required. However, it has CAS. The tool checks if CAS can be disabled.
- Result: PERMITTED (with conditions). The student must activate “Press-to-Test” or an equivalent exam mode to disable the CAS functionality before entering the exam.
Example 2: Economics SL Student
- Inputs: Subject = Individuals and Societies, GDC = No, CAS = No, Other Prohibited = No.
- Logic: This subject does not require a GDC, but a four-function or scientific calculator is allowed. The calculator has no prohibited features.
- Result: PERMITTED. A simple calculator is acceptable for Economics.
Example 3: Any Student with a Prohibited Device
- Inputs: Subject = Any, Features = Has Wi-Fi or a QWERTY keyboard.
- Logic: The device has a feature explicitly banned by the IB.
- Result: NOT PERMITTED. Devices with wireless communication or full keyboards are never allowed.
How to Use This ‘use of calculators in ib dp examinations 2025’ Calculator
Follow these simple steps to determine if your calculator is compliant:
- Select Your Subject Group: Choose the academic group of the exam you’re taking. The rules are most stringent for Group 4 (Sciences) and Group 5 (Mathematics).
- Check Your Calculator’s Features: Tick the boxes corresponding to your device’s capabilities. Be sure to identify if it’s a GDC or has CAS. If you’re unsure, check your calculator’s manual or the manufacturer’s website.
- Review the Result: The tool will instantly provide one of three outcomes:
- PERMITTED: Your calculator is fine to use.
- PERMITTED (with conditions): Your calculator is allowed, but you MUST activate an “Exam Mode” (like Press-to-Test) to disable certain features like CAS or stored notes.
- NOT PERMITTED: Your calculator has a prohibited feature and cannot be used in the exam.

Key Factors That Affect the use of calculators in ib dp examinations 2025
- Subject Requirements: Mathematics and Sciences explicitly require a GDC for certain papers. Other subjects may only allow a basic four-function calculator or none at all.
- GDC vs. Non-GDC: A Graphic Display Calculator (GDC) is a device that can plot graphs. This is a mandatory tool for subjects like IB Mathematics AA and AI.
- CAS (Computer Algebra System): A CAS can manipulate mathematical expressions symbolically (e.g., solve for ‘x’). This feature is generally prohibited unless disabled via an exam mode. Using a CAS-enabled calculator without activating exam mode is a breach of regulations.
- Press-to-Test / Exam Mode: This is a special mode on many advanced calculators (like the TI-Nspire and HP Prime) that temporarily disables stored files, programs, and specific functions like CAS. Invigilators will check for this.
- Prohibited Hardware: Any calculator with a QWERTY keyboard, wireless communication (Bluetooth, Wi-Fi), or that needs to be plugged into mains power is strictly forbidden.
- Stored Data: You are not allowed to have notes, programs, or any user-created data on your calculator that could provide an advantage. All memory must be cleared before the exam, which is often handled by activating exam mode.
Frequently Asked Questions (FAQ)
1. What is the difference between a GDC and a CAS calculator?
A GDC (Graphic Display Calculator) can plot graphs of functions. A CAS (Computer Algebra System) calculator can also do that, but it can additionally perform algebraic manipulations, like solving equations symbolically. All CAS calculators are GDCs, but not all GDCs have CAS.
2. Can I use a CAS calculator like the TI-Nspire CX II CAS?
Yes, but ONLY if you put it into the proper “Press-to-Test” mode, which disables the CAS functionality. If you don’t, it is considered an act of academic misconduct.
3. What is “Press-to-Test” mode?
“Press-to-Test” is a feature on Texas Instruments calculators that temporarily restricts access to pre-existing programs, documents, and certain functions to make the device compliant for exams. Other brands like HP and Casio have similar “Exam Modes.”
4. What happens if I forget to put my calculator in exam mode?
An invigilator should spot this during pre-exam checks. If found during the exam, the calculator will likely be confiscated, and you may be reported for academic misconduct, which has severe consequences.
5. Do I need a calculator for my English or History exam?
No, calculators are generally not permitted or needed for Group 1 (Studies in Language and Literature), Group 2 (Language Acquisition), or most Group 3 subjects besides Economics.
6. Can I use my smartphone’s calculator app?
Absolutely not. Smartphones and any device with internet access or communication capabilities are strictly prohibited in all IB exams.
7. What are some IB-approved calculator models?
Popular approved GDC models include the TI-84 Plus series, the TI-Nspire CX II (non-CAS version), and the Casio fx-CG50. For more options, see our guide on recommended IB calculators.
8. Where can I find the official IB calculator policy for 2025?
The definitive guide is published on the Programme Resource Centre, which your school’s DP coordinator can access. Key documents are the “Calculators guidance for examinations booklet 2025” and the “Use of calculators in IB DP examinations 2025” document.
