A radiographer positions a patient, selects an imaging protocol, adjusts the equipment, checks image quality and recognises when the result is unsafe to accept. The sequence may take minutes. Inside it sit years of study, supervised practice, judgement and feedback.
The capability becomes available for evaluation through the work itself.
Within the Unified Skills Map, Practical Skills are the capabilities people use to perform actions and achieve results in concrete situations. They answer a direct question: what can this person actually do, under these conditions, toward this result?
Familiarity with a subject and recall of a method provide weak evidence for that claim. Practical capability becomes credible when the person can perform the action to an appropriate standard.
The distance between explanation and performance
Professional education has examined the distance between knowledge and action for decades. Miller’s framework for clinical assessment separated “knows”, “knows how”, “shows how” and “does”, allowing educators to distinguish knowledge from demonstrated and workplace performance (Miller, 1990). Although developed for medicine, the framework captures a problem shared across professional fields: evidence of understanding cannot carry an unrestricted claim about performance.
Knowledge
Demonstrated performance
Workplace performance
- Knows
- Knows how
- Shows how
- Does
A trainee may explain every stage of a difficult client consultation and still struggle to listen while planning, notice confusion, adapt an explanation, manage time and reach a responsible next step with a real client. Another person may complete a familiar routine competently while holding only a thin explanation of why it works. Knowledge can support action, and repeated action can deepen understanding, yet each remains a distinct capability claim.
Research on professional competence presents performance as integrated and contextual. Epstein and Hundert include communication, knowledge, technical skills, clinical reasoning, emotions, values and reflection within professional competence (Epstein and Hundert, 2002). Schön’s account of professional practice highlights the judgement required when uncertainty prevents mechanical application of a formula (Schön, 1983). These traditions place visible action inside a wider professional reality shaped by thought, experience and context.
The Unified Skills Map preserves Practical Skills as a distinct family because integrated performance still contains an action that must be completed. A civil engineer may calculate a load correctly and remain unable to conduct a safe structural assessment. A lawyer may understand the doctrine governing confidentiality and still produce a clause that fails to protect the client’s interests. In both cases, the practical claim remains unfulfilled.
An action with conditions and consequences
A useful Practical Skill statement reveals what the person does and the result being pursued.
The observable centre is the action itself: interpreting an image, facilitating a discussion, building a forecast, negotiating an agreement, configuring a network or editing a film. Strong verbs help, although the verb alone rarely completes the definition. “Analyse” could describe a narrow calculation, an entire market assessment or the reasoning process behind a conclusion.
Professional meaning comes from the conditions surrounding that action. Audience, tools, standards, available information, time pressure and uncertainty all influence what competent performance requires. Koeppen et al. describe competence as connected to real-world demands and context, with modelling and assessment dependent on explicit theoretical choices (Koeppen et al., 2008). “Present information” remains incomplete until the intended audience, purpose and performance expectations become visible.
Direction comes from the result being pursued. “Use operational data” leaves the purpose concealed. “Use operational data to identify the source of a production delay” connects the action to a professional outcome. Results may appear as a decision, explanation, diagnosis, agreement, safe process or well-managed interaction.
This construction also disciplines vague labels. “Communication” may refer to communication theory, language proficiency, interpersonal behaviour or several practical actions. “Explain a technical procedure to a non-specialist audience so that the next action is understood” makes a Practical Skill visible. The statement gives the performance a setting, a purpose and a basis for judging quality.

Three practical families
The Unified Skills Map organises Practical Skills into Specific, General and Technological forms.
Specific Practical Skills derive their meaning from a profession, discipline, task or field of practice. Interpreting medical imaging, drafting a commercial contract, estimating cost of capital and performing structural analysis all depend on specialised standards and consequences
Specific Practical Skills: performing specialized actions.
Actions such as presenting information, coordinating work, facilitating a discussion or providing constructive feedback can travel across many roles. The Unified Skills Map classifies them as General Practical Skills, with quality still shaped by audience, purpose and environment. Presenting evidence to a regulator calls for a different performance from presenting an emerging concept to a creative team.
General Practical Skills: acting effectively across professional contexts.
The technological family focuses on operational control of tools, software, platforms and technical environments. Using SQL, operating a contract-management system and creating a parametric model in CAD qualify because the technology must be used to perform meaningful work.
Technological Practical Skills: using tools to perform work.
Real work frequently combines the three. A data analyst may use SQL, build a customer-retention model and present the findings to executives. The technological action, specialised analytical work and broadly applicable presentation can be classified separately even though one professional performance brings them together.

Practice must change what the person can do
Practical Skills develop when practice alters the quality, reliability or range of performance. Repetition alone records time spent.
Ericsson, Krampe and Tesch-Römer describe deliberate practice as focused activity designed to improve specific aspects of performance through feedback and correction (Ericsson, Krampe and Tesch-Römer, 1993). Later debate has narrowed claims about how much deliberate practice explains differences in achievement across domains, while preserving an important developmental principle: practice designed around improvement differs from routine repetition.
Variation prepares the action for changing conditions. Hatano and Inagaki distinguish routine expertise, marked by efficient execution in familiar settings, from adaptive expertise, which supports adjustment when the usual procedure no longer fits (Hatano and Inagaki, 1986). A technician may follow a troubleshooting script successfully until the fault falls outside the script. Stronger practical capability includes recognising the mismatch and adapting the approach responsibly.
Knowledge and deeper capacities shape this development around the action. Conceptual Knowledge helps the technician understand the mechanism producing the fault. Contextual Knowledge clarifies the equipment, environment and operating history. Analytical Capacity supports the selection and interpretation of evidence. Pressure may also require Emotional Capacity. The Practical Skill remains the ability to diagnose and resolve the fault.
Clear classification changes the developmental response. A conceptual misconception requires work on understanding, while limited fluency requires further performance under relevant conditions. Confidence work cannot compensate for missing practice. Precision directs support toward the capability that is actually limiting performance.
Performance claims need matched evidence
Practical Skills can usually be observed through performance, yet the observation still requires judgement. Case difficulty, available resources, stress, support and chance can all influence one demonstration. Simulations may reproduce important professional demands while omitting the consequences of actual practice. Workplace observation offers richer realism with less control, and complex work may distribute contribution across teams and technologies.
Assessment scholarship therefore favours complementary evidence. Van der Vleuten and Schuwirth locate quality in the design of the assessment programme as a whole (van der Vleuten and Schuwirth, 2005). Baartman et al. examine competence assessment through criteria including authenticity, cognitive complexity, fairness and fitness for purpose (Baartman et al., 2007). Gulikers, Bastiaens and Kirschner describe authenticity through the task, physical and social setting, expected result and assessment criteria (Gulikers, Bastiaens and Kirschner, 2004).
Useful evidence may include an observed procedure, completed professional output, simulation, work sample, recorded demonstration or portfolio of performances. The chosen form should reproduce the demands that matter for the capability claim and allow quality to be judged.
A polished dashboard confirms that a dashboard was produced. Further criteria are needed to determine whether the person selected appropriate measures, used the software independently, interpreted the data accurately and communicated a defensible conclusion. One artefact may support several capability claims, although each inference needs its own basis.
Verbs with professional weight often improve the statement: draft, diagnose, facilitate, configure, forecast, evaluate, negotiate. Their meaning still depends on conditions, expected results and standards of quality. “Evaluate an investment opportunity using incomplete market and financial evidence” gives assessors a clearer object than the label “analysis”.
Knowledge and judgement remain active throughout practical performance. Evidence of those supporting capabilities can enrich the assessment, while the practical claim still depends on seeing what the person can accomplish through action.
