What is a portfolio of evidence? A practical guide for ILM learners

If you are taking a current ILM leadership qualification, you will not sit an exam and you will not write assignments. You will build a portfolio of evidence. For many learners this is unfamiliar, so this guide explains exactly what a portfolio is, what counts as evidence, and how to build a strong one from work you are already doing.

What a portfolio of evidence actually is

A portfolio of evidence is a purposeful, organised collection of authentic material that shows how you meet the assessment criteria of your qualification. The key word is purposeful. It is not a folder of everything you have ever done at work; it is a curated set of evidence, each piece chosen because it proves a specific criterion.

For the current ILM suites — City & Guilds 8723 (Level 3) and 8725 (Level 5) — the portfolio is the entire method of assessment. Assessment is a portfolio of evidence, centre-devised and internally set and marked. There are no exams and no written assignments. Assessment is graded pass/fail.

The golden rule: workplace evidence

All evidence for the skills learning outcomes must be generated in the workplace or a realistic working environment, and must be valid and attributable to you.

Read that twice, because it shapes everything. The skills you claim have to be demonstrated through real activity — leading a meeting, managing a performance conversation, delivering a project, handling a change. This is a strength, not a hurdle: it means you develop and prove capability you actually use, rather than memorising content for a test. But it also means the qualification only works if you are in a role where that activity happens, which is why choosing the right level matters so much.

Two further requirements sit alongside the workplace rule:

• Validity — the evidence genuinely shows what it claims to show.
• Attributability — it is clearly your own work. Your centre confirms attribution with a centre statement, and where evidence involves others (a team output, for example) you explain your specific role.

What counts as evidence?

The handbooks list the permitted sources of evidence. They include:

• Workplace documentation and records — team development plans, project implementation reports, meeting agendas and minutes, training materials
• Video clips, up to a maximum of 15 minutes
• Projects
• Reflective accounts, journals and logs
• Assessment observation
• Witness testimonies

This list is not exhaustive — other sources are permitted where they are valid and attributable. In practice, most strong portfolios combine several types: a reflective account that tells the story, backed by a workplace document that proves it happened, and a witness testimony from a colleague that confirms your role.

The main evidence types, and when to use each

Reflective accounts A written first-person account of something you did at work, explaining the situation, your actions, your reasoning and the outcome. Reflective accounts are the backbone of most portfolios because they let you narrate how your activity meets the criteria. See reflective account examples for how to write one that satisfies an assessor.

Workplace documents and records Real artefacts from your job — a team development plan, a project report, meeting agendas and minutes, training materials you produced. These are powerful because they are direct proof. The skill is redacting confidential information while keeping the document meaningful.

Witness testimony A statement from someone who saw you do something — usually your line manager or a colleague — confirming what you did and how. Witness testimony is ideal for evidencing behaviours that leave no paper trail, like how you handled a difficult conversation. See witness testimony examples.

Observation Your assessor (or a qualified observer) watches you perform an activity, such as chairing a meeting, and records what they see against the criteria.

Video clips A recording of you in action, up to a maximum of 15 minutes. Useful for capturing something live, like leading a briefing, when an observer cannot attend.

Professional discussion A structured, recorded conversation with your assessor where you talk through your practice. It is excellent for drawing out depth and filling small gaps.

How to map evidence to criteria

The part learners underestimate is mapping — showing which criterion each piece of evidence satisfies. A single strong piece of evidence often covers several criteria across one or more units; this is called holistic evidence and it is efficient. A simple approach:

1. Start from the unit's assessment criteria, not from your pile of evidence.
2. For each criterion, ask "what have I actually done that shows this?"
3. Choose the evidence type that proves it most directly.
4. Record the mapping so the assessor can follow it — evidence with no mapping is just paperwork.

Leader Study Pro is built around this workflow: you upload evidence, map it to criteria, and receive assessor feedback, so the portfolio becomes easier to manage as it grows.

Paper or electronic?

Either is fine. You can keep a paper-based portfolio or use an electronic portfolio (ePortfolio) system. Most learners now use an ePortfolio because it makes mapping, feedback and version control far easier.

A note on AI

You can use AI tools to help you learn and organise your thoughts, but your evidence must be your own authentic work, generated from your real activity — AI use is governed by the City & Guilds position statement on AI and your centre's guidance. A portfolio that is genuinely yours is also, conveniently, the one that passes.
