OWM OJT and Mentoring Resources (for State Labs)

This website was created in support of an interim Office of Weights and Measures course: “Fundamentals of Metrology and LAP Problem Preparation” during 2020 due to the closure of onsite NIST seminars and the impact to State weights and measures programs.  Each student registering and attending this course is required to have a laboratory metrologist on staff who will serve as an on-site mentor before and during the seminar.

Green puzzle pieces with words Laboratory Metrology OJT & Mentoring Resources

Mentoring requirements in support of students attending this interim training are available here.  These “requirements” may also provide useful guidelines in laboratory administrative procedures for anyone doing mentoring/training of new staff even if not participating in this interim training. Developing the knowledge, skills, and abilities as a “trainer” is supplemental to those needed to perform good measurement in the laboratory and care should be considered when assigning staff to train and mentor others, making sure they have the aptitude and passion for helping and guiding others to learn metrology.

The following materials and resources were developed and are being provided on one page to support on-the-job training and mentoring for State Weights and Measures laboratories.  Materials may be useful for other laboratories as well and are not restricted in their use.

Laboratory Auditing Program (LAP) Problems

State laboratory staff conducting training or mentoring new staff need to be familiar with OWM Training Requirements in Handbook 143, Table 2 as well as the requirements for the Fundamentals of Metrology LAP Problems (Zip File with Instructions and All Resources/Forms).  For Mass Echelon I, the LAP problems are published within NISTIR 5672:2019, Advanced Mass Calibration and Measurement Assurance Program for State Calibration Laboratories (2019 Ed).

Recorded Adobe Sessions (Training and Lab Metrology Info Hours)

Recorded training sessions are available on “train the trainer” topics as well as on-the-job training.  These sessions were conducted by OWM staff and are available.  Because some of these items were completed prior to several updates in the latest valid procedures, any noted differences should always be referenced to the latest valid methods.  Some of the reference materials and slides used in these recorded sessions are posted in the next section.  These sessions are only available to State laboratory staff. Please contact OWM for links and password details.
