To standardize calculator usage during U.S. Coast Guard mariner credentialing examinations, the National Maritime Center (NMC) is implementing the following:

Beginning January 1, 2024, all mariners testing at a regional examination center, monitoring unit, or federal/state maritime academy will be issued a Texas Instruments TI-30XIIS calculator to use during their examination(s). All mariners should become familiar with the use of this calculator prior to their scheduled examination. The TI-30XIIS operating manual may be reviewed at TI-30XIIS Quick Reference Guide. After December 31, 2023, no other calculators will be allowed in the examination room.

Any questions, concerns, or feedback should be directed to the NMC Customer Service Center by e-mailing IASKNMC@uscg.mil or calling 1-888-IASKNMC (427-5662).
