5CO02 Common Mistakes (and How to Avoid Them)

You can know the 5CO02 material well and still lose marks, because Evidence-based practice is a unit where how you argue matters as much as what you know. Most referrals come from a short list of predictable, fixable mistakes, and markers see the same ones in cohort after cohort.

This guide walks through eight of the most common 5CO02 mistakes. For each one you will see what it looks like on the page, why it costs marks, and what to do instead. Read it before you draft if you can, and use it again as a checklist before you submit.

In this guide you'll learn

• The eight mistakes behind most 5CO02 referrals
• What each mistake actually looks like in a submitted answer
• Why markers penalise it, in plain terms
• What to do instead, plus a quick self-check for your draft

Mistake 1: Offering opinion instead of evidence

What it looks like: confident statements with nothing behind them. Flexible working improves engagement. Managers should communicate more. These may be reasonable views, but nothing on the page shows where they come from.

Why it costs marks: 5CO02 exists to test evidence-based practice, so an unevidenced claim fails the core purpose of the unit. A marker cannot award analysis marks for assertion, however sensible the assertion sounds.

What to do instead: back every significant claim with something a marker can check: organisational data, a credible published source, or clearly labelled practitioner experience weighed against other evidence. If you cannot find evidence for a claim, either soften it or cut it.

Mistake 2: Describing data without interpreting it

What it looks like: a paragraph that walks through a table line by line. Turnover was highest in year three. Absence rose in the warehouse. The numbers are restated in words, and then the answer moves on.

Why it costs marks: description proves you can read, not that you can analyse. The marks in data questions sit in interpretation: what the pattern suggests, what might explain it, and what it means for the organisation.

What to do instead: for every figure you mention, add the so-what. Compare it to something, suggest an explanation, note a limitation, or connect it to a decision. If a sentence only restates the table, it is not earning marks.

Mistake 3: No line from analysis to recommendation

What it looks like: pages of decent analysis followed by recommendations that seem to arrive from nowhere, or recommendations so generic they could follow from any analysis. Improve communication. Invest in training.

Why it costs marks: the unit is about making decisions from evidence, so the join between your findings and your proposed actions is precisely what is being assessed. If the marker cannot trace a recommendation back to the analysis, the chain is broken.

What to do instead: draft each recommendation as the final sentence of an argument, not a fresh idea. A useful pattern is: the evidence shows this, the most convincing explanation is this, therefore the organisation should do this, and success would be measured like this.

Mistake 4: Weak or missing sources

What it looks like: a reference list of consultancy blogs and anonymous websites, one textbook cited for everything, or long stretches of the answer with no citation at all.

Why it costs marks: evidence is only as strong as its source, and this unit explicitly asks you to judge credibility. Leaning on weak sources shows the marker you have not applied the unit's own core skill to your own work.

What to do instead: build a short list of credible sources early: peer-reviewed journal articles, CIPD research and reports, respected academic texts and reputable professional publications. Cite them accurately in the referencing style your centre requires, and say briefly why a source is credible when the task invites that judgement.

Mistake 5: Ignoring stakeholder value

What it looks like: analysis and recommendations framed purely in terms of cost or efficiency, with employees, customers and other stakeholders absent. Or the reverse: everything about employee experience, with no organisational case at all.

Why it costs marks: creating value for the organisation and its people is one of the unit's central themes. An answer that sees only one stakeholder misses half of it.

What to do instead: for each recommendation, name who gains and how: the organisation, its people, and where relevant customers or the wider community. Acknowledge tensions honestly, because recognising that a saving for the business may cost employees something is exactly the kind of balanced thinking that earns marks.

Mistake 6: Misreading the command verbs

What it looks like: a task says evaluate and the answer explains. A task says analyse and the answer lists. The content may be relevant, but it is doing the wrong job.

Why it costs marks: command verbs define the depth required. Explaining when asked to evaluate caps your answer at description, and markers must assess against the verb in the brief, not the answer you preferred to write.

What to do instead: highlight the verb in every task before you start, and check what it demands. Analyse means break something down and examine relationships. Evaluate means weigh strengths and weaknesses and reach a judgement. Discuss means present more than one side. Reread each finished answer asking whether it does what its verb asked.

Mistake 7: Leaving the calculation and table questions thin

What it looks like: a rushed table, minimal working, a one-line comment, and a fast exit to the essay-style questions where the writer feels safer.

Why it costs marks: the data tasks carry their own criteria, and they are often where referrals happen. A thin answer here cannot be rescued by strong writing elsewhere.

What to do instead: give the data tasks the time their marks deserve. Show your calculations clearly, present results in labelled tables or charts, refer to each visual in your text, and write a proper interpretation of what the results suggest. If you are unsure how much working to show, ask your tutor before the deadline rather than guessing.

Mistake 8: Relying on a single type of evidence

What it looks like: an answer built entirely on the numbers in the brief, or entirely on literature, or entirely on personal experience, with the other sources of evidence ignored.

Why it costs marks: evidence-based practice, as writers such as Barends and Rousseau describe it, means combining multiple sources: research findings, organisational data, practitioner expertise and stakeholder perspectives. Using one source alone is the very habit the approach exists to correct.

What to do instead: for each significant conclusion, aim to triangulate. Let the data show the pattern, the literature suggest explanations and options, and stakeholder or practitioner insight test whether a proposed action would work in context. Where sources disagree, say so and weigh them, because that is critical thinking made visible.

A before and after example

Here is the difference in miniature, using a fictional distribution company with rising absence. The weak version reads: absence has increased, which is a problem, so the company should improve wellbeing. The claim is vague, nothing is interpreted, and the recommendation is generic enough to follow from anything.

The stronger version notes that the absence data shows the rise is concentrated in night-shift roles, that staff survey comments from those teams repeatedly mention fatigue and rota gaps, and that published guidance on shift work points the same way, so the company should review night rota design first and measure absence in those teams over the following two quarters. Same topic, similar length, very different marks, because every move is evidenced and connected.

A quick self-check before you submit

1. Check every task against its command verb and the criteria in your brief.
2. Highlight claims that carry no evidence, then either evidence them or cut them.
3. Confirm each data question includes calculation, clear presentation and written interpretation.
4. Trace every recommendation back to specific findings, and forward to who benefits from it.
5. Review your sources for credibility and your references for accuracy against your centre's required style.
