Which term best describes a discrete skill?

• A. Discrete
• B. Continuous
• C. Serial
• D. Open

Answer: (A)

A discrete skill is defined by a definite start and finish, usually involving a single, brief movement. That clear beginning and end is what makes the term describe this kind of skill best—for example, throwing a ball or flipping a light switch has a precise moment it starts and a precise moment it ends.

In contrast, continuous skills flow without a distinct endpoint, like running or swimming laps, where the action keeps going. Serial skills are a sequence of several discrete movements performed in a specific order to complete a larger task, so they’re not a single discrete action. Open skills relate to performing in a changing environment, which is about where and how performance occurs rather than how the action itself is structured.
