/ / Percent POLICIES AND GUIDELINES FOR TAKING NRC WRITTEN EXAMINATIONS Page 1 of 2 Each examinee shall be briefed on the policies and guidelines applicable to the examination category (written, operating, walk
-through, and/or simulator test) being administered. The examinees may be briefed individually or as a group. Facility licensees are encouraged to distribute a copy of this appendix to every examinee before the examination begins. All items apply to both initial and requalification examinations, except as noted.
Part A: General Guidelines
- 1. [Read Verbatim]
Cheating on any part of the examination will result in a denial of your application and/or action against your license.
- 2. If you have any questions concerning the administration of any part of the examination, do not hesitate to ask them before starting that part of the test.
- 3. SRO applicants will be tested at the level of responsibility of the senior licensed shift position (i.e., shift supervisor, senior shift supervisor, or whatever the title of the position may be). 4. You must pass every part of the examination to receive a license or to continue performing license duties. Applicants for an SRO
-upgrade license may require remedial training in order to continue their RO duties if the examination reveals deficiencies in the required knowledge and abilities.
- 5. The NRC examiner is not allowed to reveal the results of any part of the examination until they have been reviewed and approved by NRC management. Grades provided by the facility licensee are preliminary until approved by the NRC. You will be informed of the official examination results about 30 days after all the examinations are complete.
Part B: Written Examination Guidelines
- 1. [Read Verbatim]
After you complete the examination, sign the statement on the cover sheet indicating that the work is your own and you have not received or given assistance in completing the examination.
- 2. To pass the examination, you must achieve an overall grade of 80.00 percent or greater, with 70.00 percent or greater on the SRO
-only items, if applicable. If you take only the SRO portion of the exam (as a retake or with an upgrade waiver of the RO exam), you must achieve an overall grade of 80.00 percent or better to pass. SRO
-upgrade applicants who do take the RO portion of the exam an score below 80.00 percent on that part of the exam can still pass overall, but may require remediation. Grades will not be rounded up to achieve a passing score. Every question is worth one point. 3. For an initial examination, the nominal time limit for completing the examination is 6 hours0.25 days <br />0.0357 weeks <br />0.00822 months <br /> for the RO exam; 3 hours0.125 days <br />0.0179 weeks <br />0.00411 months <br /> for the 25
-question SRO
-only exam; 8 hours0.333 days <br />0.0476 weeks <br />0.011 months <br /> for the combined RO/SRO exam. Notify the proctor if you need more time.
- 4. You may bring pens, pencils, and calculators into the examination room; however, programmable memories must be erased. Use dark pencil to facilitate machine grading.
POLICIES AND GUIDELINES FOR TAKING NRC WRITTEN EXAMINATIONS Page 2 of 2 5. Print your name in the blank provided on the examination cover sheet and the answer sheet. Print your name on the first page of the examination, the facility will retain the examinations and you will want to see your own examination during the exam review.
- 6. Mark your answers on the answer sheet provided. Use the paper provided, and write o n the back side of the pages to document your thought process.
If you have recorded an incorrect answer on your answer sheet, carefully erase and mark the correct answer. If the scan-tron and chief examiner cannot determine which answer you intended, the answer will be marked as incorrect. If you have an 'e' column do not mark any answer in that column. It will not be considered as a 'd' answer, it will be marked as incorrect.
If you mark answer d. on your examination and c. on the answer sheet, your official answer is c. even if d. is the correct answer.
- 7. If you have any questions concerning the intent or the initial conditions of a question, do not hesitat e to ask them before answering the question. Note that questions asked during the examination are taken into consideration during the grading process and when reviewing applicant appeals.
Ask questions of the NRC examiner or the designated facility instructor only. A dictionary is available if you need it.
When answering a question, do not make assumptions regarding conditions that are not specified in the question unless they occur as a consequence of other conditions that are stated in the question. For example, you should not assume that any alarm has activated unless the question so states or the alarm is expected to activate as a result of the conditions that are stated in the question. Similarly, you should assume that no operator actions have been taken, unless the stem of the question or the answer choices specifically state otherwise.
Finally, answer all questions based on actual plant operation, procedures, and references. If you believe that the answer would be different based on simulator operation or training references, you should answer the question based on the actual plant
. 8. Restroom trips are permitted, but only one applicant at a time will be allowed to leave. Avoid all contact with anyone outside the examination room to eliminate even the appearance or possibility of cheating.
- 9. When you complete the examination, assemble a package that includes the examination answer sheets and cover sheet and give it to the NRC examiner or proctor.
Leave the remaining materials at your workstation, face
-down. Remember to sign the statement on the examination cover sheet indicating that the work is your own and that you have neither given nor received assistance in completing the examination. The scrap paper will be disposed of immediately after the examination.
- 10. After turning in your examination, leave the examination area as defined by the proctor or NRC examiner. If you are found in this area while the examination is still in progress, your license may be denied or revoked.
- 11. Do you have any questions?
