A programmable calculator is neither automatically permitted nor automatically prohibited in an exam. The deciding factor is the current rule for your institution, your subject, the specific part of the exam, and the exact model. Some authorities exclude custom programs. Others work with functional limits, model lists, or an approved exam mode. A reset can delete content, but it does not necessarily change the device class. Therefore, check programs, memory, graphics, communication, and mode separately.
In short: "Programmable," "memory-capable," "graphics-capable," and "CAS-capable" are different features. Only the examination rule determines which of these are permitted in your case.
Important note: Which aids are permitted is determined by the rules of your specific exam. Check the examination regulations, the announcement of permitted aids, and the exam instructions together. Clarify any ambiguities in writing with the responsible body. Spickboy does not provide any universal approval.
You can find further categorizations regarding exams and aids in the Spickboy™ Guide.
What does "programmable calculator" mean?
Technically, a calculator is programmable if users can create or load their own command sequences, programs, scripts, or reusable routines. However, examination boards do not use the term uniformly. Some include other features, such as text or formula memory, graphics, symbolic mathematics, or communication interfaces.
A typical borderline case: Your list of permitted aids only says "not programmable." Your model cannot run its own scripts, but it does have stored formulas, a graphic display, or an interface. In this case, the product designation is not sufficient. You must clarify which features the examination board actually covers with its wording.
Official university rules show these differences:
- The Examination Board for Economics at the University of Wuppertal associates "not programmable" in its area with, among other things, the absence of custom programs, text and formula memory, wireless communication, and graphics.
- The Department of Business and Economics at the Philipps University of Marburg cites the absence of text and formula memory for its area; different requirements may apply for individual subjects and exams.
- The Institute of Business Administration at the University of Rostock excludes additional functions within its scope, including graphical representation, matrix operations, and spreadsheets.
None of these definitions apply automatically to another university or exam.
Seven features you should check separately
| Feature | What it means | What you must check |
|---|---|---|
| Programmability | Custom or loaded programs, scripts, and routines | Does the rule prohibit the ability to program, stored programs, or both? |
| Text or note memory | Freely retrievable alphanumeric content | Are your own texts or files excluded? |
| Formula memory | Stored expressions, libraries, or routines | Does the rule cover formulas separately from programs? |
| Graphics | Display of function graphs or diagrams | Is only a simple scientific calculator intended? |
| CAS | Symbolic transformation and solving of mathematical expressions | Is CAS intended, limited, or excluded? |
| Communication | Wireless, cable, or other data exchange | Which connection or data transmission does the rule prohibit? |
| Exam mode | A mode that temporarily limits certain functions | Does the rule recognize exactly this mode and this model? |
A USB port alone is proof of neither permission nor exclusion. Likewise, programmability does not prove that a device can store text. Every property requires individual proof from the official manual of the exact model.
WTR, GTR, CAS, and MMS clearly distinguished
These abbreviations help with orientation, but they are not universal seals of approval:
- WTR – Scientific calculator (Wissenschaftlicher Taschenrechner): The range of functions depends on the respective definition. "WTR" can mean different things in two different sets of examination regulations.
- GTR – Graphics-capable calculator (Grafikfähiger Taschenrechner): It can display function graphs. This does not automatically imply free programmability or CAS capability.
- CAS – Computer Algebra System: It supports symbolic mathematical operations. Whether it may be used depends on the exam and the part of the exam.
- MMS – Modular Mathematics System: According to the IQB guidelines valid up to and including the 2029 exam year, an MMS combines several mathematics modules, such as computer algebra, graphics, dynamic geometry, probability distributions, or spreadsheets.
The IQB categories describe the functional framework of joint pool tasks. They do not approve a single model for every German federal state.
If you would like to distinguish between device classes first, the comparison Scientific vs. Programmable Calculator shows which features lie behind the two terms and why they do not automatically lead to exam approval.
Why reset, memory deletion, and exam mode are not the same
- Memory deletion removes certain user-generated content.
- Reset restores memory areas or settings depending on the model.
- Exam mode restricts functions using a technical procedure.
None of these measures answers the question of permission on its own. The Department of Finance at the University of Stuttgart clarifies for the exams listed there: A programmable calculator remains programmable even after a reset and is not permitted within this framework. This is a local example, not a general university rule.
An exam mode only helps if the responsible authority recognizes it for the specific model and defines the activation and control procedures.
How examination rules can be structured
Examination boards choose different paths:
- Functional limit: Programs, text, formulas, graphics, or communication are individually excluded.
- Device category: For example, a defined scientific calculator or a specific MMS is permitted.
- Positive list: Only explicitly named models or model series are provided for.
- Negative list: Certain models or functions are excluded; additional criteria may still apply.
- Course or exam specification: The introduced technology or written instructions for the specific exam count.
- Exam mode: A specific mode must be activated and controllable.
Several paths can apply simultaneously. A model list may additionally require memory deletion or an exam mode.
Three DACH examples – no common rule
Germany: common pool framework, implementation by the federal states
For common Abitur tasks, the IQB guidelines distinguish between tasks without digital aids, with a simple scientific calculator, and with an MMS. They are a functional framework. The article Calculators in the 2027 Abitur explains which technology and models apply in a specific state in 2027.
Austria: standardized AHS mathematics exam
The implementation guidelines as of March 2026 exclude, among other things, internet, intranet, Bluetooth, and cellular communication, as well as access to private data in this exam context. A designated exam mode is activated under the supervision of the invigilator. This does not automatically apply to every Austrian exam.
Switzerland: Federal Vocational Baccalaureate Examination
The SBFI list of aids as of August 12, 2025 specifies concrete models and categories for the Federal Vocational Baccalaureate Examination. Subject, specialization, and exam part determine the appropriate line. The list is not a rule for all Swiss schools or universities.
An IHK (Chamber of Industry and Commerce) exam also has no blanket calculator approval. According to Section 13 (3) of the IHK Berlin examination regulations, the exam date, location, and permitted tools and aids in its scope are communicated in writing or electronically. Check the current information for your specific exam additionally.
What do you need to check before your exam?
- Determine the exam: Note the institution, educational program or course of study, subject, exam format, part, and date.
- Open the primary source: Search for examination regulations, lists of aids, task instructions, and possible addenda on the official website.
- Identify the rule type: Is it about a category, functional limit, model list, or exam mode?
- Identify the model exactly: Compare the complete model name, additional letters, and, if applicable, the software version.
- Compare features individually: Check programs, text, formulas, graphics, CAS, communication, transmission, and mode.
- Clarify in writing: Provide the responsible body with the model, exam date, and the unclear function. Keep the response.
- Plan a backup: If the situation is not clarified in time, use only an unambiguously permitted substitute.
Next step: Open the official information on aids first. Then compare your complete model – not the other way around.
Depending on the regulations, a non-permitted device can be assessed as an unauthorized aid. The article Attempted Deception in an Exam shows how procedures and potential consequences can vary.
Frequently asked questions about programmable calculators
Is a programmable calculator prohibited in every exam?
No. Some exams exclude this capability, while others provide for certain systems or modes. The decisive factor is the current rule for the institution, subject, date, and exam part.
Does a programmable calculator become non-programmable through a reset?
Not necessarily. A reset can change content or settings, while the ability to execute programs remains. Check the device manual and the examination rule separately.
Is a GTR (graphics-capable calculator) automatically programmable?
No. Graphics capability and free programmability are different features. A specific model can have both, but the abbreviation GTR does not prove it.
Are CAS calculators fundamentally prohibited?
No. Some exams provide for CAS or MMS, others only for a scientific calculator or no digital aid at all. Even a provided category can be tied to a course, exam part, and functional limits.
Is an activated exam mode sufficient?
No. The rule must recognize the mode for the specific model. The model list, software status, activation time, and control procedure may additionally be important.
What documents do I need for a model inquiry?
State the full model name, software version, exam, subject, date, and the function that is unclear. Link the official manual and the specific rule on aids. A mere shop description is not enough.
Conclusion: First the rule, then the model
"Programmable" is only one of several properties. A reliable decision only arises when you check the current examination rule, the full model name, and every relevant feature together. A reset, exam mode, or an old approval does not replace this comparison. If a requirement remains unclear, a precise written model inquiry is more reliable than a blanket yes or no.
