How to change careers
Changing careers is four steps, in this order: name one target role, measure the gap between the skills you already have and the skills that role requires, close that gap with evidence rather than certificates alone, and apply where evidence is what gets screened. Everything else — courses, networking, CV rewrites — is in service of those four. This guide walks each step, with the data behind every role we map.

Tell us what you do now and where you want to get to. We return the target role, the exact gap, and a phased plan to close it.
Step 1 — Pick a target you can name
"Something in tech" is not a target. "Data analyst" is. The difference matters because every later decision — which course, which project, which job to apply for — is only answerable once the destination is a specific occupation with a known skill profile.
Pick on three criteria, in this order: work you can tolerate doing daily for years, demand in the markets you can actually work in, and pay that clears your floor. Interest alone burns out; pay alone burns out faster.
If you genuinely do not know, take the three-minute role quiz or browse careers by sector. Pick something provisional and move — you will learn more from two weeks of doing than two months of reading.
Step 2 — Measure the real gap
Every occupation in this directory carries a skill profile from O*NET and ESCO: typically eight to twenty competencies, each with an importance rating. Your gap is that list minus what you can already evidence.
Most career changers overestimate the gap badly. Project management, writing clearly, reading a budget, handling difficult stakeholders, working a ticket queue — these are rated highly in far more occupations than people assume, and you likely have years of them. What is usually genuinely missing is two to five technical or domain-specific skills, not the whole list.
Do this concretely: open your target's role page, go through the skill list, and mark each one "can evidence", "can do but cannot prove", or "cannot do". The middle column is your quickest win — it needs a portfolio piece, not a course.
Step 3 — Close the gap with evidence
A finished course is weak evidence on its own; a thing you built or shipped is strong. Sequence the work in phases rather than collecting certificates: foundations first, then core craft, then applied practice on something real, then a portfolio piece that a hiring manager can look at in ninety seconds.
Free material is entirely sufficient for most of this — see the free learning guide for how to choose and finish it. What matters is that each completed step leaves a verifiable artefact behind, dated, that you can point at.
On Freecoursera each proven skill goes into your Skill Wallet with its evidence attached, and every live job on the platform is scored against it automatically. That is the mechanism that turns study into applications.
Step 4 — Apply where skills count
Applying too late is the most common failure. Start applying when you can evidence roughly 70 per cent of a job's required skills — not 100. Job descriptions are wish lists, and the remaining 30 per cent is what the first six months on the job are for.
Target employers who screen on skills rather than titles: see the skills-based hiring guide. And apply to enough of them. A career changer's hit rate is lower per application; the fix is volume plus evidence, not a longer wait.
A realistic timeline
Months 1–2: target chosen, gap mapped, foundations underway. Months 3–5: core skills, first portfolio piece. Months 6–8: applied project, second piece, first applications out. Months 9–12: interviews, offers, first role at entry band. Adjacent moves compress this substantially; regulated professions do not compress at all.
Five mistakes that cost months
1. Researching instead of starting. Two weeks of comparison shopping between courses teaches you nothing about the work.
2. Collecting certificates. Ten unfinished courses read worse than one shipped project.
3. Hiding the past. Your previous career is the differentiator, not the liability — a nurse moving into health data beats a generic analyst for those roles.
4. Waiting for readiness. Readiness arrives after the first few interviews, not before.
5. Quitting first. Financial pressure narrows your options and pushes you to accept the wrong role. Change while employed where you can.

Questions people ask
- Am I too old to change careers?
- No. The constraint is rarely age — it is time and evidence. Someone with fifteen years of work behind them usually transfers more skills than they expect (stakeholder handling, prioritisation, domain knowledge) and needs to prove fewer new ones than a school leaver. Map the gap before you assume the answer.
- How long does a career change take?
- For most people moving into an adjacent role, six to nine months part-time is realistic. A complete change of field with a large technical component takes twelve to eighteen. The number of skills you have to prove from scratch is the best predictor — not the job title distance.
- Do I need to go back to university?
- Usually not, and it is often the slowest option. For occupations at O*NET job zones 1 to 3, employers weight demonstrated skills and short credentials most heavily. Regulated professions (medicine, law, some engineering) are the genuine exception.
- Should I take a pay cut?
- Frequently yes, for the first move — then recover. Entry-level pay in a new field typically sits at 60 to 85 per cent of the role's median, and mid-level within two to three years. Look at the pay bands on each role page before you commit.
- What if I pick the wrong target role?
- Most of the early work transfers. Foundational skills overlap heavily across adjacent occupations, so a change of target in month three usually costs weeks, not months. Picking something is better than researching indefinitely.
