Sports, Exercise & Health Science Internal Assessment: what criteria are configured?
The table below is the 4-criterion, 24-mark model currently configured in iBacalao. Treat it as a reference until the subject-specific evidence pack has been reviewed.
| Criterion | Name | Marks |
|---|---|---|
| Research Design | Research Design | 6 |
| Data Analysis | Data Analysis | 6 |
| Conclusion | Conclusion | 6 |
| Evaluation | Evaluation | 6 |

How do Sports, Exercise & Health Science IA criteria work?
Each criterion describes a different part of the assessment, and its mark-band descriptors explain what evidence and reasoning earn credit.
Research Design
Research Design
What this criterion assesses
The methodology (purpose and practice) used to address the research question effectively communicated: a focused question in a specific sport/exercise/health context, the relevant variables (or groups being compared), methodological choices explained, and enough detail to reproduce the investigation.
Mark band descriptors
Criterion: Research design (0–6) — the extent to which the report effectively communicates the methodology (purpose and practice) used to address the research question: - 0: The report does not reach a standard described below. - 1–2: The research question is stated without context; methodological considerations are stated but not developed; the description of the method lacks the detail needed to reproduce the investigation. - 3–4: The research question is outlined within a broad sport, exercise or health context; methodological considerations (variables or comparison groups, protocol, participant considerations) are described; the method could be reproduced with few ambiguities. - 5–6: The research question is described within a specific and appropriate context; methodological considerations associated with collecting relevant and sufficient data are explained; the description of the method allows the investigation to be reproduced. [Adapted from the sciences scientific-investigation model per the 2026 SEHS guide structure; not verbatim band wording.]
Common mistakes
- Research question without a specific sport, exercise or health context
- Comparison groups or variables not operationally defined
- Method missing the detail needed to reproduce the protocol
- Ethical/safety considerations for human participants ignored
Data Analysis
Data Analysis
What this criterion assesses
Data recorded, processed and presented in ways relevant to the research question: clear and precise communication (tables, graphs, units, significant figures), appropriate consideration of uncertainties and variability, and processing carried out appropriately and accurately.
Mark band descriptors
Criterion: Data analysis (0–6) — the extent to which the data is recorded, processed and presented in ways relevant to the research question: - 0: The report does not reach a standard described below. - 1–2: The recording and processing of data is communicated but is neither clear nor precise, with limited consideration of uncertainties; processing contains major omissions, inaccuracies or inconsistencies. - 3–4: The communication of the recording and processing of data is either clear or precise; uncertainties and variability are considered with some significant omissions; processing relevant to the research question is carried out with some significant errors. - 5–6: The communication of the recording and processing of the data is both clear and precise; uncertainties and participant variability are appropriately considered; the processing relevant to the research question is carried out appropriately and accurately. [Adapted from the sciences scientific-investigation model per the 2026 SEHS guide structure; not verbatim band wording.]
Common mistakes
- Tables or graphs missing units, labels or consistent precision
- Human variability and measurement uncertainty ignored
- Processing errors that propagate into the findings
- Processed results that don't address the research question
Conclusion
Conclusion
What this criterion assesses
The research question answered with regard to the analysis and the accepted scientific context — a justified conclusion consistent with the data and its limitations, compared against published research or accepted theory, and considering the implications of the findings for real-world sport, exercise or health practice.
Mark band descriptors
Criterion: Conclusion (0–6) — the extent to which the research question is answered with regard to the analysis and the accepted scientific context: - 0: The report does not reach a standard described below. - 1–2: A conclusion is stated that is relevant to the research question but is not supported by the analysis; comparison to the accepted scientific context is superficial; implications of the findings are not considered. - 3–4: A conclusion is described that is relevant to the research question but not fully consistent with the analysis; some relevant comparison to the accepted scientific context is made; implications of the findings for real-world examples are stated. - 5–6: A conclusion is justified that is relevant to the research question and fully consistent with the analysis; it is justified through relevant comparison to the accepted scientific context (published research, theory); and the implications of the findings on real-world examples (e.g. whether a measured difference is meaningful for actual performance or health) are discussed. [Adapted from the sciences scientific-investigation model per the 2026 SEHS guide structure, including the SEHS-specific real-world implications descriptor; not verbatim band wording.]
Common mistakes
- Conclusion claims more than the data and its variability support
- No comparison with published values or accepted theory
- Statistical significance confused with practical significance for performance
- Real-world implications of the findings never considered
Evaluation
Evaluation
What this criterion assesses
Evidence of evaluation of the investigation methodology with suggested improvements: specific weaknesses and limitations (protocol, participant variability, measurement) weighed for their relative impact on the conclusion, with realistic improvements that address them.
Mark band descriptors
Criterion: Evaluation (0–6) — the extent to which the report provides evidence of evaluation of the investigation methodology and suggested improvements: - 0: The report does not reach a standard described below. - 1–2: Generic methodological weaknesses or limitations are stated; realistic improvements are stated. - 3–4: Specific methodological weaknesses or limitations are described; realistic improvements that are relevant to the identified weaknesses are described. - 5–6: The relative impact of specific methodological weaknesses or limitations on the conclusion is explained; realistic improvements relevant to the identified weaknesses are explained. [Adapted from the sciences scientific-investigation model per the 2026 SEHS guide structure; not verbatim band wording.]
Common mistakes
- Generic weaknesses ("human error") not specific to this protocol
- Improvements unrelated to the weaknesses identified
- Relative impact of each limitation on the conclusion not weighed
- Participant-related limitations (motivation, learning effects) ignored
