PRC List of Allowed Calculator Models for 2026

by

Are you preparing for a board examination? Before buying a scientific calculator, check if its exact model is included in the PRC list of allowed calculators. Even if a calculator is non-programmable, it does not automatically mean you can use it during the examination.

The Professional Regulation Commission issued Resolution No. 1809, Series of 2024, updating its list of non-programmable calculators allowed in licensure examinations. However, some Professional Regulatory Boards have their own calculator policies. Always read your examination program to determine which list applies to your board exam.

PRC List of Allowed Calculators

The following calculator models are included in Annex A of PRC Resolution No. 1809, Series of 2024. Check the model number printed on your calculator carefully, as similarly named models may have different approval statuses.

These entries were checked against Annex A of the resolution included in the supplied PRC document.

Are Newer Versions Allowed?

Not automatically. In its September 18, 2026 advisory, PRC clarified that an approved calculator model does not automatically include its other versions, variants, or newer releases. Having the same functions or appearance is not enough.

For example, if you are buying a calculator marked “2nd edition,” check whether that exact version is covered by an official PRC approval. Do not rely solely on the seller’s claim that it is “board-exam approved.”

PRC also clarified that submitting a calculator for evaluation does not mean it has already been approved. The model must be expressly authorized through an applicable official issuance.

What About Other Casio Models?

Several readers have asked about the Casio fx-991EX, fx-991CW, and fx-991MS. These models do not appear in the updated Annex A shown above.

However, the resolution also contains a provision allowing calculators from Memorandum Circular No. 21, Series of 2009, subject to specific exclusions. Some boards may also follow their own approved lists. If your calculator is not in the table, ask PRC to confirm whether it is allowed for your particular examination.

The resolution specifically excludes the following Casio models from its provision for older-listed calculators:

  • fx-991ES
  • fx-991ES PLUS
  • fx-570ES PLUS

It references the earlier prohibition on the fx-991ES and fx-991ES PLUS and identifies the fx-570ES PLUS as a model repeatedly used for cheating, including through modifications to transmit and receive data.

Please take note that the Casio fx-570ES PLUS is different from the Olympia ES-570ES PLUS. The Olympia model is included in the updated list, provided it has a transparent casing.

Before Bringing Your Calculator

Read the examination program for your upcoming board exam before deciding which calculator to bring. Professional Regulatory Boards may have their own calculator lists or may prohibit calculator use entirely. Being included in the general PRC list does not mean a calculator can be used in every examination.

Once you have checked the applicable rules, make sure your calculator is working properly. Test its keys, display, and battery before examination day. Practice solving problems with the same unit so you will be familiar with its functions and settings.

For models with a transparent-casing requirement, check the actual unit you are buying. The official list specifies this condition for the Canon F-789SGA, Sharp EL-W531TH-WH, and Olympia ES-570ES PLUS.

Reminders

Examinees are allowed only one calculator inside the examination room. PRC personnel will inspect it before the examination on each examination day.

Borrowing and lending calculators are prohibited. Once the examination has started, replacement is also prohibited unless authorized by the Commission under the circumstances stated in its advisory. Make sure your calculator is ready before reporting to your testing center.

  92. Why is CASIO MX-120B not included in the list? It’s not even a scientific calculator so definitely it’s not programmable.
