International Qualification Framework (IQF)
Level Descriptors
Current Version: Edition 02 · 2026
Last updated: September 2026
The International Qualification Framework (IQF) provides a standardised and internationally relevant structure for aligning qualifications, certifications, and professional capability within the global Strength and Conditioning (S&C) profession. Introduced by the International Universities Strength and Conditioning Association (IUSCA) in 2024, the IQF is independently overseen by the International Qualification Framework Independent Regulatory Council (IQF-IRC), which supports the governance, quality, and continued development of the framework.
The IQF Level Descriptors build on this earlier work by defining more clearly what professional progression means across the eight levels of the framework. They provide a common structure for understanding the development of practitioner reasoning, judgement, autonomy, responsibility, and the ability to operate effectively under increasing complexity and uncertainty.
About the IQF Level Descriptors
The IQF Level Descriptors were developed to provide a clearer account of what progression in S&C practice looks like.
The eight levels of the IQF had already been established through earlier work. The purpose of the Level Descriptor project was therefore to define the professional capabilities represented at each level, rather than to create a new qualification structure.
Within the framework, progression is not defined primarily by the accumulation of facts, completion of particular tasks, use of prescribed methods, qualifications held, job titles, or years of experience. Instead, progression reflects increasing sophistication in how practitioners define problems, interpret information, reason under uncertainty, make decisions, manage complexity, take responsibility, and identify and correct error.
The same broad scientific principles apply across all eight levels. What changes is the quality and robustness of reasoning, the degree of autonomy and responsibility, the scale and complexity of the problems being addressed, and the practitioner's capacity to make effective decisions when information is incomplete.
How the Descriptors Were Developed
The IQF Level Descriptors were developed through a two-stage expert consultation led by Alex Wolf on behalf of the IUSCA and the IQF-IRC.
Contributors were experienced practitioners, academics, and educators with substantial expertise across applied, academic, and professional contexts in S&C and related disciplines. The consultation was designed to ground the descriptors in professional practice and to shape, refine, and pressure-test their content. It was not intended to produce an empirical research study or formal consensus statement.
In the first stage, 19 contributors were invited, with 12 completed responses received. Contributors provided written input on how practitioner expertise develops in real settings. Responses were reviewed to identify recurring developmental themes across reasoning, outcome definition, adaptation, evidence use, complexity management, autonomy, and error correction.
In the second stage, the draft Level 1 to 8 descriptors and accompanying Overview Table were circulated to 30 contributors, including participants from the first stage and additional reviewers. 12 responses were received. Feedback was incorporated through essential and recommended refinements that strengthened clarity while preserving the underlying logic of the framework.
The resulting descriptors represent the institutional position of the IUSCA, informed and pressure-tested through expert input. Acknowledgement as a contributor reflects participation in the consultation process and does not imply endorsement of the philosophical position, final wording, or institutional conclusions.
Underlying Philosophy
The descriptors are grounded in a view of S&C as explanatory problem-solving directed at real physical systems.
Practitioners identify meaningful problems, develop explanations, select and implement interventions, monitor outcomes, and continually identify and correct error. Effective practice therefore depends on more than the possession of information or the application of established methods. It requires practitioners to reason about why particular outcomes occur, why an intervention may work, under what conditions an explanation is likely to hold, and how decisions should change when expectations are not met.
Science is understood within the framework as a systematic process of explanation, reasoning, empirical scrutiny, criticism, and revision. As practitioners progress through the IQF, they are expected to use knowledge more effectively, reason more robustly under uncertainty, manage greater complexity, and become increasingly effective at identifying and correcting error.
At the broadest level, the framework describes progression from externally guided, rule-following behaviour through increasingly conditional and context-sensitive reasoning towards scientific, system-level, and field-shaping judgement.
IQF Level 1 to 8 Descriptor Overview
The Overview Table is the primary representation of the developmental logic of the IQF Level Descriptors. It maps all eight IQF levels against seven dimensions of professional practice:
Reasoning Orientation · Outcome Definition & Intent · Adaptation & Stimulus Reasoning · Relationship to Evidence & Scientific Reasoning · Complexity & Variable Management · Autonomy & Responsibility · Error Detection & Correction
The full written descriptors below provide additional depth and should be read alongside the Overview Table rather than as separate or independent criteria.
Full IQF Level Descriptors
Level 1: Foundational Learner
At Level 1, the practitioner operates within a highly structured and supervised environment and follows instructions and established procedures without yet recognising them as choices among possible methods. Behaviour is compliance-driven rather than reasoning-led, with decisions guided externally and explanations provided by others.
The practitioner recognises simple cause-and-effect relationships but does not yet reliably connect actions to outcomes without guidance. Intended outcomes are broad, implicit, or defined by supervisors, and the practitioner relies on direction to understand purpose and intent.
Training and practice are understood to create change, but adaptation is assumed rather than evaluated. The practitioner follows prescribed instructions without independently adjusting stimulus, dose, or structure.
Scientific knowledge is treated primarily as factual information to be learned and recalled, with no expectation of independent interpretation or critique. Complexity is experienced as linear, with attention typically limited to a single variable at a time.
Autonomy is minimal. The practitioner acts under direct supervision and does not hold responsibility for decision outcomes. Errors are identified and corrected externally, with limited reflective capability.
Level 2: Supervised Practitioner
At Level 2, the practitioner applies simple rules and procedures to routine situations with increasing familiarity and demonstrates emerging awareness of underlying principles. Reasoning remains constrained but is no longer entirely passive. The practitioner begins to recognise that methods are choices rather than fixed rules, although they may revert to method-led behaviour under pressure or in unfamiliar contexts. This reversion is characteristic of the stage rather than a failure of competence.
The practitioner can articulate simple outcomes when guided, although decision-making may default to familiar methods rather than intent under pressure. There is increasing recognition that different stimuli produce different effects, but sensitivity to dose and context remains limited.
Scientific information and established principles are applied through straightforward explanations and are generally treated as authoritative rather than interpretive. The practitioner manages a small number of variables but experiences difficulty prioritising when multiple factors are present.
Autonomy remains limited, with decisions subject to supervision and approval. The practitioner responds appropriately to feedback but does not routinely anticipate errors or unintended consequences without prompting.
Level 3: Developing Practitioner
At Level 3, the practitioner demonstrates conditional reasoning and adapts established rules to context, although reasoning remains inconsistent under uncertainty. Temporary regression under pressure is characteristic of this stage and reflects the normal demands of developing independent judgement rather than a deficit in the practitioner. Decision-making shows increasing independence but lacks robustness.
Outcomes are articulated with greater clarity, although prioritisation remains variable and methods may still be selected before intent is fully resolved. Adaptation is managed reactively, with adjustments commonly driven by short-term signals rather than longer-term considerations.
The practitioner begins to interpret scientific evidence but does not consistently distinguish correlation from causation. Complexity is experienced through the interaction of multiple variables, and trade-offs are recognised but not yet managed reliably.
Autonomy is partial and bounded by role scope. The practitioner takes responsibility for assigned work within that scope and adapts their approach when solving problems. Reflection typically occurs after errors rather than through proactive monitoring or anticipation.
Level 4: Practitioner
At Level 4, the practitioner demonstrates defensible judgement grounded in relevant principles. Decisions are explicitly justified: the practitioner can state why a course of action was chosen in relation to the intended outcome and accepts accountability for that choice within a defined scope. Reasoning is deliberate and articulable, although delayed or indirect effects are not yet anticipated consistently.
Outcomes are explicitly defined at an appropriate level of resolution, with competing objectives acknowledged and managed. The practitioner deliberately matches stimulus, dose, and structure to intended adaptation and balances stress and recovery with intent.
Scientific evidence is interpreted contextually, with recognition of its limitations and uncertainty. Evidence informs decisions rather than directing them automatically.
The practitioner manages multiple interacting variables and demonstrates effective prioritisation. Autonomy is established within role scope, with clear accountability for decisions and outcomes. Where applicable, the practitioner supervises routine activities of others and contributes to evaluation and improvement within their area of practice.
Errors are identified through embedded feedback processes, and adjustments are made without defensiveness or reliance on external correction.
Level 5: Developing Scientific Practitioner
At Level 5, the practitioner integrates multiple principles simultaneously and demonstrates reasoning that remains robust under pressure. Decision-making reflects conditional logic and explicit management of trade-offs. The practitioner moves beyond justifying individual decisions to anticipating delayed and indirect consequences. Reasoning is provisional and conditional, acknowledging what cannot yet be known.
Outcomes are framed provisionally and adjusted as conditions evolve. The practitioner anticipates delayed and indirect effects and demonstrates deliberate restraint, including choosing not to intervene where the risks or costs outweigh the expected benefit.
Scientific evidence is weighed according to relevance, quality, uncertainty, and decision risk. The practitioner avoids over-interpretation and recognises when available evidence is insufficient to warrant action.
Complexity is managed through prioritisation rather than simplification, with an expectation of non-linear responses. The practitioner may lead a defined practice area and reviews and develops their own and others' performance and decision quality.
Assumptions are tested actively, and error correction is applied proactively before problems escalate, with reduced reliance on external intervention.
Level 6: Scientific Practitioner
At Level 6, the practitioner demonstrates consistently high-quality judgement across complex and unpredictable contexts. Reasoning is transferable, resilient, and explicit. Evidence and relevant scientific principles are used to generate explanations, test assumptions, and correct error under uncertainty. The practitioner also shapes the reasoning conditions for less experienced colleagues by designing structured learning opportunities, surfacing assumptions, and modelling deliberate decision-making.
Outcomes are managed as interconnected systems rather than isolated targets, balancing short- and long-term effects. Intervention is strategic, and unnecessary action is avoided.
Scientific evidence from multiple sources is integrated with explicit attention to uncertainty, causal relevance, and decision risk. Probabilistic models are used where appropriate without being treated as substitutes for explanation. The practitioner acts effectively with incomplete information and revises decisions as new evidence emerges.
Complexity is characterised by anticipation of second-order effects and indirect consequences. The practitioner holds full professional responsibility and supports multi-practitioner systems, teams, or performance environments.
Learning environments are intentionally designed to support reflection, criticism, and belief revision, both personally and across others.
Level 7: Advanced Scientific Practitioner
At Level 7, the practitioner operates increasingly through pattern recognition and anticipatory judgement, including at the interfaces between disciplines. Reasoning reflects deep understanding of system behaviour and interaction. Expert judgement, however rapid or experience-based, remains explainable and open to scrutiny.
Outcomes are shaped by influencing environments, structures, and processes rather than through isolated interventions. Trade-offs are accepted as unavoidable features of complex systems and are managed transparently.
Adaptation is managed at organisational scale, with deliberate judgement applied to when intervention is and is not warranted. Scientific models and assumptions are critically evaluated and used to explain decisions rather than to provide post hoc justification.
The practitioner manages extensive complexity through system-level prioritisation and holds strategic responsibility for the quality of decision-making across teams. Responsibility includes contributing to professional knowledge and practice within the field.
The practitioner establishes error-correcting cultures in which near-misses are surfaced, decisions are reviewed without blame, and challenges to dominant professional narratives are judged according to standards of rigour, transparency, and evidence. Dogmatic practices are actively challenged.
Level 8: Field-Shaping Practitioner
At Level 8, the practitioner demonstrates meta-reasoning about professional practice and contributes to shaping how the field understands quality, judgement, and evidence. They influence field-wide developmental structures, including training pathways, mentoring frameworks, professional standards, policy, and governance. This level represents a shift from operating within existing systems to shaping how those systems are defined. It is a qualitatively different mode of practice rather than a simple extension of Level 7.
Outcomes are framed at policy, governance, or paradigm level, with competing values, impacts, risks, and long-term consequences considered. Influence extends beyond individual organisations to the profession as a whole.
The practitioner extends and, where necessary, redefines professional practice and its underpinning explanatory frameworks. Field-shaping authority does not exempt the practitioner from standards of rigour. Paradigm-level challenges must be transparent in reasoning, accountable in process, and open to peer scrutiny.
The practitioner recognises that some uncertainty may remain practically irreducible while continuing to treat explanations, assumptions, and models as open to improvement.
Responsibility includes stewardship of professional standards and scientific integrity. Structures for ongoing criticism, error correction, learning, and revision are established to support the continued credibility and development of the profession.
Status and Revision of the Descriptors
The IQF Level Descriptors represent the current institutional position of the IUSCA, informed and pressure-tested through expert consultation.
They are provisional, criticisable, and open to revision. As better explanations, evidence, and professional insights emerge, the descriptors may be revised in versioned form.
This webpage contains the current official version of the IQF Level Descriptors. Material revisions will be recorded below so that changes to the framework remain transparent over time.
