Free career tests compared: what each one tells you
The free career tests people take most often, side by side: what each measures, what it's good for and what to do next. Written by OffLadder, with our bias stated.
The short answer
The free career tests most people take measure different things. The O*NET Interest Profiler and Holland code (RIASEC) tests measure vocational interests and link to occupations. 16Personalities and other type quizzes describe personality, which is a weaker guide to work. Skills assessments such as England's National Careers Service suggest roles from what you're good at. Use one interest test for vocabulary, then try a small real task in two of the directions it suggests.

The tests side by side
| Test | What it measures | Cost | Good for | Watch out for |
|---|---|---|---|---|
| O*NET Interest Profiler (U.S. Department of Labor) | Vocational interests on six RIASEC areas | Free | Vocabulary for what you like, linked to occupation profiles | U.S. pay and training data; check local routes |
| CareerOneStop Skills Matcher (U.S. Department of Labor) | Self-rated workplace skills | Free | Finding occupations that use skills you already have | Self-ratings are only as good as your honesty about them |
| CareerOneStop Work Values Matcher | What you need from work, such as independence or recognition | Free | Telling a bad job apart from the wrong kind of work | Values describe conditions, not tasks |
| Holland code (RIASEC) tests from other publishers | The same six interest areas | Usually free, with paid reports | A quick three-letter summary | Quality varies; check who made it |
| 16Personalities | Personality type | Free, with paid extras | Talking about how you like to work | A type says little about which work you'll enjoy |
| National Careers Service skills assessment (England) | Skills and work preferences | Free | Suggesting roles from what you're good at | Job profiles are for England |
| CareerExplorer | Interests, personality and work preferences | Free, with a paid tier | A long list of possible careers | Long lists need cutting down before they help |
| CliftonStrengths | Strengths themes | Paid | Language for how you work best | Describes how you work, not which job |
| OffLadder (ours) | Not a test: suggests directions from your answers | Free to start | A direction plus a small experiment to try | Built by us; judge it by what you learn from the experiment |
Which one to take first
- If you don't know where to start, take the O*NET Interest Profiler. It's free, takes about ten to fifteen minutes and links straight to occupations.
- If you already have a shortlist, skip the tests and research the work itself.
- If you are in England and want to start from your skills, try the National Careers Service assessment.
- If you have a result you don't know what to do with, read it as a list of directions to test.
What a test can't tell you
A test describes what you said you like. It can't tell you how a Tuesday in the job feels, whether you like the people who do it, or whether the pay works for your life. Those come from trying a small piece of the work and talking to someone who does it.
Questions people ask
- What is the most accurate free career test?
- For vocational interests, the O*NET Interest Profiler is free and has a published technical manual describing how it was developed and tested. Accuracy here means it measures interests consistently; it can't tell you whether you will enjoy a particular job.
- Is 16Personalities a career test?
- It is a personality questionnaire. It can be a fun conversation starter, but personality types are a weaker guide to work than interest inventories or trying the work itself.
- Should I pay for a career test?
- Try a free interest test first. Pay only when a report clearly gives you something the free version doesn't, such as a detailed strengths report you plan to use with a coach or manager.
- What should I do after taking a career test?
- Take the top two or three suggestions, read what a normal week contains in each, and do a small real task from one of them within a fortnight.
- Where does OffLadder fit?
- OffLadder is not a test. It suggests directions from your answers and gives you a small experiment for each. Answer five quick questions, plus one optional. Before signing up, see your first direction, what in your answers points to it and the first step of an experiment. Create a free account to see the rest and save your read.
