How to become a Data Scientist
Becoming a Data Scientist isn't one leap — it's a ladder. You can start as a Data Entry Specialist and climb from there, with each rung showing the real time it takes and what it pays. Here's the honest path, and what a technology route actually costs along the way.
The path, rung by rung
Each step is a real role you can hold. The time is how long to reach it; the pay is a national figure for that rung.
- Data Entry SpecialistExcel skills, attention to detail
- Data AnalystSQL, basic statistics, visualization
- Business Intelligence AnalystBI tools, advanced SQL
- Data ScientistPython/R, ML algorithms, statistics
- Senior Data ScientistDeep ML expertise, business acumen
Start this week
You don't need to commit to the whole climb today. Here's one small, real thing you can do this week.
Spend 20 minutes on the first free lesson of freeCodeCamp. Set a timer if you need to.
If it's boring, you've learned something real. If the 20 minutes vanish, you've learned more. Either way you moved.

- You don't need a college degree to take the first step.
- These are national figures. What you'll actually earn and what training costs shift with your city and the current market.
Common questions
How long does it take to become a Data Scientist?
Charted lays it out as a 5-step path. You can start as a Data Entry Specialist right away; reaching Senior Data Scientist typically takes 5+ years. You don't have to climb every rung — many people stop at a step that already fits their life.
What does it cost to get started as a Data Scientist?
Getting started costs less than the destination. The entry role, Data Entry Specialist, asks for excel skills, attention to detail — not an expensive degree. The bigger costs come with the later rungs.
Can you become a Data Scientist without a degree?
You can start without one. The first rung, Data Entry Specialist, needs excel skills, attention to detail — no college degree to begin. Degrees and licenses come later, as you climb toward Senior Data Scientist.
