Professional Development

ISWM gives you access to the publications, training courses, and resources you need to succeed in your career.

Handbook 44

Handbook 44 is published by the National Institute of Standards and Technology (NIST) as part of its responsibility for cooperating with States in securing uniformity of weights and measures laws and methods of inspection. It is published every year following the annual meeting of the National Conference on Weights and Measures (NCWM).

Staying up to date with the Handbook is obviously critical to all professional weighing technicians and salespeople. As such, demonstrating knowledge of the Handbook is a prerequisite for achieving the ISWM Certifications

ISWM periodically offers Handbook 44 training and testing, typically in conjunction with either the ISWM Conference and Exposition (even numbered years) or ISWM Technical Training events (odd numbered years). Check back here to see when new programs will be offered.
