How to use the Skills Gap Checker
- 1. Choose a roleData analyst, full stack, data scientist, DevOps, QA, security or Java.
- 2. Tick your skillsOnly what you could show in a project or interview.
- 3. See your gapGet a readiness score and what to learn first.
How the score works
Each role lists core skills that most job posts for it ask for, and good-to-have skills that make you stronger. Core skills count double. For the default Data Analyst role, ticking Excel, SQL and data cleaning (3 of 6 core) and Python (1 of 5 good to have) gives (3 × 2 + 1) ÷ (6 × 2 + 5) = 41%. With nothing ticked, the result shows Data Analyst readiness at 0% and lists every core skill under learn first.
Your ticks are saved in this browser, so you can return as you learn and watch the score rise.
Using the result well
- Be strict: tick a skill only if you have used it in a project or could answer interview questions on it.
- Close core gaps first; good-to-have skills matter once the basics are solid.
- Check real job posts in your city and target companies, because each employer's needs differ.
- Show, don't list: one project that uses several skills beats a long skills section.
The skill lists are a general guide drawn up by Uncodemy, not a survey of job postings. Each role links to a step-by-step plan, such as the data analyst roadmap or the DevOps roadmap. If you are unsure which role to aim for, start with the tech career path quiz.
Frequently asked questions
Why do core skills count double?
Because missing a core skill usually rules you out, while missing a good-to-have skill only makes you slightly less competitive.
Can I check more than one role?
Yes. Switch roles at the top; ticks are remembered for each role.
Is the Skills Gap Checker free?
Yes, the Skills Gap Checker is free. The first time you see your first skills gap, you are asked for your name and WhatsApp number once. After that, this and every other Uncodemy tool opens straight away without the form.
