Three cognitive levels of exam questions
NERC describes recall, application, and analysis questions. Build practice that checks more than recognition of definitions.
Recall checks factual knowledge. Application uses knowledge with the supplied information. Analysis combines concepts and evaluates a possible response. Use the official sample questions and explanations to see how these demands differ.
After a practice question, identify whether your difficulty was remembering a fact, using it with the data, or comparing possible responses. Return to the approved material for the knowledge you were missing.
Worked practice exercise
A practice set asks you to (A) state a definition, (B) use a given rule with supplied data, and (C) compare possible responses using several concepts. Which NERC cognitive level best describes each task?
Show answer
A: recall. B: application. C: analysis.
The distinction is the thinking required: remembering information, using it in a situation, or combining information to make a judgment. This original exercise classifies study tasks and does not prescribe an operating response.
