Basic Competency Exam - Weighing
The NCWM Professional Certification Program provides assurance that an individual has a working knowledge of the U.S. standards for weights and measures as adopted by the NCWM. Certification is available to any individual, whether from the public or private sector whose profession requires thorough understanding of the national weights and measures standards. The Basic Competency Exam – Weighing will draw on relevant portions of Handbook 44 . In preparing the exam, NCWM has tried to be consistent with the Examination Procedure Outlines (EPO’s) for the types of devices covered in this exam. Copies of current EPO’s are available from the NIST Office of Weights and Measures.
For the purposes of this exam, weighing is limited to weighing devices (scales) covered in the Scales Code in Handbook 44 . This may include platform scales, vehicle and axle-load scales, hopper scales, animal and livestock scales, and other types used in various applications.
Format and Duration:
The examination consists of two timed sections and will include a total of 30 questions as described below. The two sections of the exam must be completed in one session and the candidate may not log off and return to the exam at a later time. Each section must be completed before moving to the next section of the exam. Once a section has been completed, the individual may not return to a previously submitted section.
The exam is OPEN BOOK. The candidate may access an unmarked copy of Handbook 44 while taking the exam. You may be asked to perform computations as part of the exam and may use a hand-held calculator. The time counter will continue to run while accessing Handbook 44 or performing calculations. The examination is to be taken alone, without assistance from any other individual.
Test instructions are provided online prior to starting the exam. Since the test is electronically graded, the answer must be marked or typed correctly. The test questions will be multiple-choice or short answer. For multiple-choice questions, you will be asked to pick the best answer from four options by clicking the button before your selected answer. For short answer questions, you must enter the specific answer, typed correctly.
