What stage of learning is reached when a learner's responses achieve 80-90% accuracy?

The stage of learning characterized by a learner's responses achieving 80-90% accuracy is identified as fluency building. At this stage, individuals have progressed beyond mere comprehension of the material and can demonstrate a degree of proficiency in their responses.

Fluency building is essential as it emphasizes both the speed and accuracy of the learner’s performance, indicating they are not only grasping the concepts but are also able to apply them consistently. This level of accuracy suggests that the learner is able to respond with little hesitation and is on their way toward mastery, where they can perform tasks with confidence.

In contrast, initial learning refers to the stage where a learner is just starting to acquire the new information or skills, and mastery pertains to achieving a significantly higher accuracy—typically closer to total correctness, often above 90%. Retention, on the other hand, focuses on the ability to remember material over time, rather than the accuracy of responses at this particular point in the learning progression. Thus, fluency building accurately captures the stage described by the question.
