The calculator must not be programmable and must not use any type of tape. Candidates can also use the Texas Instrument’s BA II Plus, HP 12c, or HP 12c Platinum calculators when taking the exams. The Hewlett- Packard 10BII is valid, but no longer available to purchase. Candidates will not be allowed to use calculators that do not comply with these restrictions.
Note from HOCK: The BA II Plus comes in a Financial and Professional version. The version allowed on the CMA exam is the Financial version.
