Module 10.1: Instructions for Evaluators
Once the instructor has ensured a simulated radiologically controlled area is pre-staged correctly,
it is recommended that the practical factors evaluation be conducted in accordance with the
following criteria listed in this section.
Although the evaluation process is broken into steps (e.g., pre-brief, donning PCs (as
applicable), performing job, exiting, etc.), the instructor should evaluate the practical factors
exercise as a whole. This will permit the student to correct a mistake within a reasonable time
Job scenarios and associated RWPs and survey maps must be developed that incorporate
The scenario used during the classroom practice lesson should not be used for the
evaluation (see Attachments 3 and 4 for sample job scenario and map).
The job scenario and simulated area should be such that the student has to make
decisions such as: the best path to the job location and how to best perform the
specific task. The student should DEMONSTRATE that they know where lower
radiation levels exist and how to proceed using this information. They should not be
allowed to verbally simulate the appropriate actions.
Student/instructor ratio should be one student per instructor.
Each student should have the undivided attention of the evaluator.
It is recommended that the design of the practical evaluation be such that the worker's
actions are graded rather than the worker's statements. If this is not feasible, verbal
responses should be limited to specific segments of the demonstration. All other
segments should be evaluated through student actions.
A list of questions permitted for the evaluation should be identified in the lesson plan
to ensure consistency within the training group (see Attachment 5 for sample
The interaction between the instructor and the student should be minimal.
Students should complete all phases of the practical factors evaluation even if an
automatic failure is recorded.
