The single-opportunity method of assessing task analysis performance allows the individual one chance to perform the behavior chain prior to training.

• A. True
• B. False
• C. It depends on the task
• D. Not applicable

Answer: (B)

The single-opportunity method checks whether the learner can complete the entire task chain in one attempt, without prompts. Its purpose isn’t tied to a strict pretraining moment; it’s about testing one-shot performance on the whole sequence. You use it to decide if the chain is mastered in a single trial, and if not, you begin training on the unmastered steps. After training, you can re-test, or you might switch to a different data-collection approach to map progress. For example, if the chain has three steps and the learner completes all three in one try, that’s a pass; if any step is missed, you treat it as not mastered and proceed with instruction. This shows that the method is defined by one-shot assessment of the entire chain, not by occurring only before training.
