Can You Take a Calculator to a CBSE Board Exam?
For ordinary CBSE Class X and XII candidates, the official guidance says calculators are barred. The exception is a defined accommodation—not permission to bring your own device.
Short answer: normally, no. CBSE’s official permitted and barred items notice lists “Calculator” among the barred items for Class X and XII examinations.
The useful distinction is not which calculator a student owns. It is whether the particular examination has permitted any calculator at all. A device bought for study does not become exam-permitted simply because its features appear limited.
The exception is an accommodation, not general permission
The notice identifies an exception for students with dyscalculia under the applicable CBSE provisions. It also says that the calculator is provided by the examination centre.
That creates a clear boundary: this is an approved accommodation, not a general invitation to carry a personal calculator. An eligible student should follow the applicable CBSE process rather than arrive with their own device.
A later instruction matters more than a product label
CBSE maintains an official Examination Circulars page for examination-related directions. Before relying on a calculator, students should check the instruction issued for their particular session and examination.
The practical reading is straightforward: unless a later CBSE instruction expressly changes the rule for that examination, ordinary candidates should treat a calculator as barred. Whether a device is described as basic, scientific, or non-programmable does not itself establish permission.
The decision to make before exam day
- For a CBSE Class X or XII board examination, begin with the published barred-items rule, not with a calculator model.
- If the dyscalculia accommodation applies, use the centre-provided calculator through the applicable CBSE process.
- If the assessment is a school test or a different examination, check that authority’s own instructions; the CBSE notice does not automatically decide every assessment.
So the real question is not “Which calculator should I take?” It is “Has this examination explicitly authorised me to use one?” For an ordinary CBSE board candidate, the answer in the published guidance is no.
