Also, the US Bureau of Labor Statistics has predicted a growth of 11.5 million data science jobs by 2026.
So, we can imagine great career growth opportunities in the field of data science.
Data Science Roadmap – 2025
So, let's begin the data science roadmap and understand the basic steps to excel in this career path.
1. Getting the right educational qualification
Though it is not mandatory to have these educational qualifications, an associate, bachelor’s, or master’s degree in computer science, mathematics, statistics, data science, or related fields can help build a strong foundation in data science.
These courses provide subjects essential to carry out various data science tasks and build machine learning algorithms.
2. Gain the foundational skills.
As mentioned earlier, data science is a multidisciplinary field, and you need to master the various foundational data science skills, from data engineering to data visualization and machine learning techniques, to build efficient data science models.
Here are some of the basic skills and knowledge you must start learning first:
- Mathematics and statistics – learn about mean, median, mode, variance, standard deviation, hypothesis testing, probability distributions, conditional probability, Bayes’ theorem, etc.
- Programming language – gain proficiency in using various programming languages like Python, R, SQL, and their libraries such as NmPy Pandas, Matplotli, ggplot2, etc. These are essentials to communicating with data bases, performing data analysis, processing, and visualizations, as well as building data science models.
- Data processing – data processing or data engineering involves skills to collect relevant data from various sources, clean them, and prepare them for analysis by handling missing values, outliers, inconsistencies, etc.
- Data analysis – you should also be efficient with various exploratory data analysis techniques, including visualizing data distributions, relationships, trends, etc.
- Machine learning – master different machine learning techniques, including supervised learning (linear regression, logistic regression, decision trees, random forests), unsupervised learning (clustering, dimensionality reduction), and model evaluation.
- Data visualization – learn to use various data visualization tools like Matplotlib, Seaborn, Plotly, Tableau, etc., to prepare charts, graphs, plots, etc.
- Domain knowledge – understanding of the business and industry you are working in is very important to help you understand the business problem properly. Understanding business also helps you plan your data science projects efficiently.
3. Gain practical experience
Once you are proficient in theoretical knowledge, aim to gain practical experience on real-world data science projects. You can do so by:
- Working on personal projects
- Participate in Kaggle competitions
- Get into internships or entry-level data science jobs
- Contribute to open-source projects and demonstrate your data science skills and knowledge
- Enroll in bootcamps to learn data science concepts practically.
4. Get Certified
Data science certifications are a great way to validate your skills and expertise in data science. These credentials also demonstrate your commitment to the data science industry and lifelong learning, creating a great impression among employers.
Data science certifications like Certified Data Science Professional (CDSP™) offered by USDSI® are highly recognized programs designed for beginners who want to step into a data science career.
5. Networking and job hunt
Start networking with other data science professionals through LinkedIn, data science events, forums, or other platforms to increase your chances of hiring. Also, regularly appear for data science job interviews to maximize your learning experience and land a job faster.
Following these steps outlined on the data science roadmap in 2025, you can get started with your data science career journey. Remember, this is just a basic guideline. However, every individual has their own journey and can choose their career path. For example, you can gain data science skills and excel in this career path without having a degree in computer science, maths, or engineering.
Conclusion
A data science career is very exciting. Ensure you have the right educational qualifications to make a solid foundation and then gain the latest in-demand industry-relevant skills to get along the data science career. Data science certifications, though not mandatory, can significantly boost your career prospectus. So, start your data science career journey today to enjoy a rewarding and successful career.
