CFA Institute strictly enforces all policies with regard to calculator usage during the exams and candidates are required to abide by the policies of CFA Institute.
Your calculator will be inspected prior to the start of the exam. Your calculator must remain on your desk in full view and proctors will continue to inspect calculators throughout the administration of the exam. Possession or use of an unauthorized calculator at the test center will result in the voiding of your exam results and may lead to the suspension or termination of your candidacy in the CFA Program. Failure by the proctors to detect an unauthorized calculator prior to the start of the exam, or your use of an unauthorized calculator at any time during the exam, does not imply that the calculator is an approved model or that your results will ultimately be reported.
Calculator covers, keystroke cards, and loose batteries are permitted in the testing room; instruction manuals are not. You may keep a small screwdriver with you if necessary to replace batteries in the BA II Plus.
