Exam - Professional - Electric Vehicle Fueling Systems (EVSE)
Electric Vehicle Fueling Systems (EVSE)
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 from the public or private sector whose profession requires thorough understanding of the national weights and measures standards. The Electric Vehicle Fueling Systems exam is based on the current version of NIST Handbook 44 and NIST Examination Procedure Outline (EPO) 30.
The exam tests knowledge, ability to interpret, and ability to apply the applicable elements of NIST Handbook 44 General Code, Electric Vehicle Fueling Systems, Timing Devices and, Appendices A, B, C, and D as well as NIST EPO 30. Some questions will require reading and responding to questions about information found on a National Type Evaluation Program (NTEP) Certificate of Conformance.
Applicants are encouraged to carefully review each module below and to use them as a guide to prepare for the exam.
The exam is in a multiple-choice format and conducted as an open book exam.
Applicants can prepare for the exam by carefully reviewing Module 4.2 Introduction to Device Control and Module 8.3 Electric Vehicle Fueling Systems and using them as a study guide. Applicants are encouraged to study the applicable sections of NIST Handbook 44 and NIST EPO 30. Examinees must understand and be able to accurately calculate measurement errors and evaluate the errors for conformance to applicable tolerances. The handbook and EPOs can be found on the NIST website. Examinees should read an NTEP Certificate of Conformance to become familiar with the format and contents. NTEP CCs can be found on the NCWM website and details about the NTEP program can be found on the NTEP Frequently Asked Questions page of the NCWM website.
Format and Duration:
The examination will be proctored either in-person or virtually. You can find details on proctoring on the NCWM website.
The examination consists of two timed sections and will include a total of 45 questions as described below. Both sections of the exam must be completed in one session, and you may not log off and return to the exam later. Each section must be completed before moving to the next section of the exam. Once a section has been completed, you may not return to a previously submitted section.
Applicants will be required to perform calculations as part of the exam. You may bring a calculator into the exam with which you are familiar, or use one provided by the proctor. Calculators with memory functions are acceptable but programmable calculators are prohibited. If you use the calculator provided by the proctor, it is your responsibility to familiarize yourself with its operation before beginning the exam.
The in-person proctor will provide the examinee with the following items, except as specifically noted below:
- A clean copy of the current edition of NIST Handbook 44 and EPO 30. The examinee may choose to use the NCWM authorized pdf file containing the appropriate sections of the NIST documents required for this test. Examinees are encouraged to learn how to use the pdf search feature to navigate the documents.
- Scrap paper for notes and calculations.
- All materials provided by the proctor must be returned to the proctor upon completing the exam. All scrap paper written on by the candidate will be shredded.
You must take the examination alone and 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 correctly. The test questions are in a multiple-choice format and may include a graphic. You must choose the best answer from the four options by clicking the button before your selected answer. There is a short practice test to familiarize you with the exam environment and to ensure that you understand the basic rules for responses.
Please visit the NCWM website for details on virtual proctoring.
Subject of Examination:
Module 4.2 - Introduction to Device Controll – 15 questions (30-minute time limit)
These questions test for knowledge, understanding, and ability to apply the basic requirements applicable to all weighing and measuring devices. This may include questions on the selection, care and use of standards, the legal basis of NIST Handbook 44, the organization of that Handbook, understanding of Fundamental Considerations, knowledge of systems of measurement units, understanding and application of General Code requirements, and understanding of the NTEP program and Certificates of Conformance.
Module 8.3 – Electric Vehicle Fueling Systems – 30 questions (60-minute time limit).
The exam will evaluate the examinee’s knowledge, understanding, and ability to apply the concepts used in inspecting and testing electric vehicle fueling systems. The exam focuses on specific concepts related to device technology, use, operations, inspection requirements, and test procedures for these devices found in NIST Handbook 44 and NIST EPO 30. Examinees must also be able to read and apply information found on NTEP Certificates of Conformance.
Passing Score and Grading:
- 70% (32 or more correct answers)
Following the completion of the examination or upon reaching the time limit for the third section, you will receive a total score for the exam and a pass/fail/statement for each section. To protect the integrity of the test questions, NCWM will not advise you of the specific questions you answered incorrectly. The Professional Development Committee will review incorrect answers in periodic reviews and will adjust scores in select cases if a question is determined to be invalid. NCWM will notify you if your score is affected.
- If you wish to challenge any of the questions, you may contact the NCWM Professional Development Committee through NCWM via email to info@ncwm.com or call (402) 434-4880.
- A certification issued under this program is valid for five (5) years.
