How do we classify motor skills, and why does it matter for coaching?
The classification of motor skills on continua, the difference between skill and ability, and how classification informs the choice of practice.
A focused WJEC A-Level PE answer on classifying motor skills, covering the main continua (open-closed, gross-fine, discrete-serial-continuous, self-paced-externally paced), the skill versus ability distinction, and how classification guides practice.

What this dot point is asking
WJEC wants you to classify motor skills on the recognised continua, justify the placement with reference to the environment, pacing and structure of a skill, distinguish skill from ability, and explain how classification helps a coach choose appropriate practice.
The classification continua
A skill rarely sits exactly at one end. A football pass, for example, is mostly open, gross, discrete and externally paced. Placing a skill on each relevant continuum gives a full picture of its demands.
Skill versus ability
The key difference is that skills are learned through practice and abilities are innate. Abilities (gross motor abilities such as strength and stamina, and psychomotor abilities such as reaction time) are the raw material that skills are built on. A coach cannot easily train abilities but can develop skills, so recognising a performer's abilities helps set realistic goals and select suitable activities.
Why classification guides practice
Classification is not an academic exercise; it tells a coach how to practise a skill. A closed, self-paced skill, performed in a stable environment, can be grooved through fixed, repetitive (massed) practice until it becomes habitual. An open, externally paced skill must be practised in varied conditions that mimic the unpredictability of the game, so the performer learns to adapt and read cues.
Examples in context
Example 1. The same action, different classification. A trampoline routine is largely closed and self-paced in training, but a gymnast performing in a noisy competition still treats it as closed because the environment does not change the movement. WJEC uses this to show classification depends on the demands of the skill, not the setting alone.
Example 2. Abilities limiting skill development. A young player with excellent co-ordination but slow reaction time may master closed skills quickly yet struggle with fast open skills. Recognising this ability profile helps the coach set realistic targets, a direct application of the skill-ability distinction.
Try this
Q1. Name the two extremes of the open-closed continuum and give an example of each. [2 marks]
- Cue. Open (changing environment, e.g. a pass in a game) and closed (stable environment, e.g. a golf swing).
Q2. Explain the difference between a discrete, a serial and a continuous skill. [3 marks]
- Cue. Discrete has a clear start and end (a penalty); serial is a chain of discrete elements (a triple jump); continuous repeats with no clear end (cycling).
Q3. Explain why a coach would use varied practice for an open skill. [2 marks]
- Cue. Open skills occur in a changing, unpredictable environment, so varied practice teaches the performer to adapt the skill and read different situations.

WJEC 20184 marksUsing a named continuum, classify a basketball free throw and a basketball lay-up in a game, and justify each placement.Show worked answer →
On the open-closed (environmental influence) continuum:
A free throw is a closed skill. The environment is stable and predictable: the player shoots from a fixed line with no opponents interfering, so the skill is largely habitual and self-paced.
A lay-up in open play is an open skill. The environment is constantly changing, with defenders and team-mates moving, so the player must adapt the skill to the situation and it is externally paced.
Markers reward naming the continuum, classifying each skill correctly, and justifying by the stability of the environment and pacing.
WJEC 20204 marksExplain the difference between skill and ability, and explain why a coach needs to understand the difference.Show worked answer →
A skill is a learned, goal-directed action that is performed consistently with maximum certainty and efficiency. It is acquired through practice.
An ability is an innate, stable and enduring trait, largely genetically determined, that underpins the performance of skills (for example, reaction time or co-ordination).
A coach needs the distinction because abilities cannot easily be trained but skills can be developed through practice. Recognising a performer's abilities helps the coach select suitable activities and set realistic, achievable goals, while skills are improved through structured practice.
Markers reward a correct definition of each, the learned versus innate point, and a coaching reason such as setting realistic goals or selecting activities.
