At some point in most public-sector careers, a line appears in a job advert that stops people short: "recognised management qualification desirable" or "evidence of leadership development". You are good at the job. Colleagues already come to you for help. But you have never managed anyone on paper, and you are not sure what the qualification even is.
Usually it is one of two names: ILM or CMI. These are the two big awarding bodies for leadership and management qualifications in the UK, and their certificates turn up everywhere in the public sector — NHS team leader programmes, council development schemes, fire and police staff progression, housing associations, universities.
This article explains what ILM and CMI are, how their levels work, how NHS and council employers actually use them, the apprenticeship routes that include them at no cost to you, how to choose between them, and — for those not yet in charge of anyone — how to evidence leadership without a management title.
What ILM and CMI actually are
ILM, the Institute of Leadership and Management, is one of the UK's largest awarding bodies for leadership qualifications. Its courses are practical and workplace-focused, delivered through colleges, training providers and employers' own programmes.
CMI, the Chartered Management Institute, is the chartered professional body for management. It awards qualifications too, but it also offers professional membership, and at the top of its ladder sits Chartered Manager status — a professional recognition of management ability, in the same spirit as chartered status in engineering or accountancy.
Both bodies award qualifications at a range of sizes as well as levels. An "award" is short, a "certificate" is medium, and a "diploma" is the full course. That flexibility is deliberate: a busy deputy ward manager can take a short award in a few months, while someone on a development scheme completes a diploma over a year or more.
Neither qualification teaches you a single method the way PRINCE2 does for projects. Instead they cover the recurring work of management — leading a team, having difficult conversations, planning workloads, managing performance, handling budgets and change — and they assess you mainly through assignments rooted in your own workplace rather than exams.
How the levels work
Both bodies pitch their qualifications at the national qualification levels, and the pattern is easy to hold in your head:
- Lower levels suit new and aspiring team leaders and supervisors — people about to take, or hoping to take, their first step into leading others.
- Middle levels suit established first-line and middle managers — ward managers, council team managers, office managers — deepening skills they already use daily.
- Higher levels suit senior managers and heads of service, dealing with strategy, organisational change and leading other leaders.
The right level is the one that matches the job you do or are about to do, not the highest one you can enrol on. Assignments draw on real workplace situations, so a qualification pitched far above your current responsibility is genuinely hard to complete well. Providers will advise you; be honest with them about your role.
The government's guidance on what qualification levels mean shows how these fit alongside GCSEs, A levels and degrees if you want the wider map.
How the NHS and councils use them
Public-sector employers use ILM and CMI in three main ways.
First, in adverts and person specifications. Team leader and manager vacancies often list a management qualification as desirable, sometimes essential for senior posts. Holding one moves you up the shortlist because it is independent evidence you have studied the craft, not just inherited the title. In the NHS, supervisory and managerial responsibility is part of what places a role at a higher pay band — the guide to Agenda for Change pay bands explains how responsibility and banding connect.
Second, in internal development schemes. Many NHS trusts and councils run their own leadership programmes for promising staff, and a large number of those programmes carry ILM or CMI accreditation, meaning you finish with a recognised certificate as well as the course. If your employer runs one, apply. It is free to you, it signals ambition in the right way, and the qualification travels with you if you move employer.
Third, as a progression signal. Appraisals in the public sector usually include a development conversation. Naming a specific ILM or CMI level as your goal gives your manager something concrete to support — and training budgets find their way to people with concrete plans.
Local government careers reward this kind of visible development particularly well, because councils contain so many services you can move between. The guide on how to get a job in local government covers how progression works there.
Apprenticeship routes that include them
Here is the part many people miss: you can gain these qualifications through a management apprenticeship while doing your existing job, with the training paid for through the apprenticeship system rather than by you.
Team leader and operations manager apprenticeships exist at levels matching first-line and middle management, and degree-level management apprenticeships run beyond that. Many providers embed an ILM or CMI qualification, or CMI membership, within them. You stay in your job, on your pay; study time is built into your working week; and you finish with both the apprenticeship and the professional certificate.
Existing staff can do apprenticeships — they are not only for school leavers, and there is no upper age limit. NHS trusts and councils use them heavily for exactly this purpose. Ask your learning and development team what management apprenticeships they support, or see our post on council apprenticeships and graduate schemes for how councils run them.
Choosing between ILM and CMI
Honestly: for most people, this decision matters less than choosing the right level and a good provider. Public-sector employers respect both names, and few adverts insist on one over the other. Still, some genuine differences can tip the balance:
- Chartered status. Only CMI can lead to Chartered Manager. If that end goal appeals, CMI is the natural ladder.
- Membership. CMI leans into ongoing professional membership, with resources and recognition letters after your name. ILM's strength is the qualification itself and its wide network of providers.
- What is actually available. In practice you will often choose whichever body accredits the programme your employer or local college runs. That is a perfectly good reason.
- Course content. Compare the units of the specific courses in front of you — one may fit your role better regardless of the badge.
If you are self-funding, compare total costs, assessment workload and tutor support between providers before the two brands. And ask your employer first: management development is one of the easiest training requests to get funded, because your employer benefits directly.
Evidencing leadership without the title
The chicken-and-egg problem is real: management jobs ask for leadership evidence, but you cannot get the title without the evidence. The way out is recognising that leadership is behaviour, not position, and public-sector recruiters are trained to score the behaviour.
You have probably led more than you think. Covered for your supervisor during absence? Trained or mentored a new starter? Coordinated the rota, led the response when something went wrong on shift, represented your team at a meeting, or run anything outside work — a sports team, a community group, a school committee? Each of those is leadership evidence.
Turn the strongest examples into structured stories — the situation, your task, what you did, what resulted — because that is how competency-based interviews score answers. Then be deliberate about collecting more: ask for the deputising opportunity, offer to induct the next starter, take the small project nobody owns. A year of that, plus a first-level ILM or CMI qualification, is a genuinely competitive package for a first team leader post.
When you are ready to look, start close to your own field. Browse live NHS jobs and council jobs and search for team leader, supervisor and deputy roles — read a handful of person specifications and you will see exactly which evidence to build next.
