Format and Duration:

  • Handbook 44 is available here.

The examination consists of three timed sections and will include a total of 50 questions as described below.  All three 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 examination is to be taken alone, without assistance from any other individual.  The exam is OPEN BOOK as follows:  The candidate may access unmarked copies of the current versions of Handbook 44 and Handbook 112, specifically:

If physical copies are not readily available, the previous PDF links may be opened on the computer to take the exam and may be accessed during the test.  The proctor will ensure the correct file is downloaded.  Candidates are encouraged to download and familiarize themselves with the PDF file in advance of taking the test.

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, short answer, or compliance/citation.  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.  For compliance/citation questions, you will be given information describing a situation and asked to assess compliance.  Answer “yes” if the situation complies based on the information provided, otherwise provide the specific legal citation if the device does not comply.  The form of the citation will typically be something like S.X.X. for a specification, T.X.X. for a tolerance, or UR.X.X. for a user requirement.  There is a short practice test to familiarize you with the exam environment and ensure that these basic rules for responses are understood.
