2.Enter the level of difficulty (LOD) of each question using a 1 - 5 (easy - difficult) rating scale (questions in the 2 - 4 range are acceptable). 3.Check the appropriate box if a psychometric flaw is identified:The stem lacks sufficient focus to elicit the correct answer (e.g., unclear intent, more information is needed, or too much needless information).The stem or distractors contain cues (i.e., clues, specific determiners, phrasing, length, etc).The answer choices are a collection of unrelated true/false statements.One or more distractors is (are) not credible.One or more distractors is (are) partially correct (e.g., if the applicant can make unstated assumptions that are not contradicted by stem). 4.Check the appropriate box if a job content error is identified:The question is not linked to the job requirements (i.e., the question has a valid K/A but, as written, is not operational in content).The question requires the recall of knowledge that is too specific for the closed reference test mode (i.e., it is not required to be known from memory).The question contains data with an unrealistic level of accuracy or inconsistent units (e.g., panel meter in percent with question in gallons).The question requires reverse logic or application compared to the job requirements. 5.Check questions that are sampled for conformance with the approved K/A and those that are designated SRO-only (K/A and license level mismatches are unacceptable). 6.Based on the reviewer's judgment, is the question as written (U)nacceptable (requiring repair or replacement), in need of (E)ditorial enhancement, or (S)atisfactory? 7.At a minimum, explain any "U" ratings (e.g., how the Appendix B psychometric attributes are not being met). 33 of 34 NUREG-1021, Draft Revision 9 ES-401 2Form ES-401-9 Q#1.LOK(F/H)2.LOD (1-5)3.
