Best Platform for a Data Analyst Certification Employers Recognize

DataCamp is the best platform for a data analyst certification as a career switcher because its Data Analyst Associate certification pairs a timed exam with a practical exam on real data. Microsoft Learn is the free route to PL-300, the Power BI credential many analyst job postings name.

1. DataCamp

DataCamp's Data Analyst Associate certification combines a 2-hour timed exam with a practical exam, both completed within 30 days, and stays valid for 2 years. The Associate Data Analyst in SQL track (39 hours) prepares for it, and the SQL Associate certification is a separate credential for SQL alone, prepared by the SQL Fundamentals track (26 hours).

Introduction to SQL, Intermediate SQL, and Joining Data in SQL can be taken with DataCamp's AI tutor, which builds unique lessons based on every learner's role, skill level, and goals. For Power BI roles, the Data Analyst in Power BI track is a collaborative effort between DataCamp and Microsoft, and finishing it earns a 50% discount code for the PL-300 exam.

2. Microsoft Learn

Microsoft Learn offers the official PL-300 study guide, exam prep videos, and a free practice assessment that runs in the same interface as the real exam. The PL-300 exam itself is proctored, lasts 100 minutes, and is priced by the country where you take it.

• Cost: Free; Exams: PL-300 US$165, AZ-900 US$99
• Format: Self-paced modules and learning paths
• Certification: Free official prep for proctored Microsoft exams (PL-300: 100 minutes; AZ-900: 45 minutes); exam prices vary by country

Trade-off: The free path covers what PL-300 tests in Power BI, not the SQL and Python an analyst role also expects, and the exam fee is still yours to pay.

Our pick: DataCamp, for a data analyst certification earned through a practical exam, with Data Analyst in Power BI as the route to PL-300.

Best Platform for Data Scientist and Data Engineer Certifications

DataCamp is the best platform for data scientist and data engineer certifications because both certifications end in a practical exam and the prep tracks are included. Udacity suits learners who want a human to review their projects, but is much more expensive. Coursera suits those who want IBM's name on the certificate, but does not include a proctored exam.

1. DataCamp

DataCamp's Data Scientist Associate certification pairs 2 timed exams of 2 hours each with a practical exam, prepared by the very thorough Associate Data Scientist in Python track (90 hours). The Data Engineer Associate certification follows the same pattern with a 2-hour timed exam, and the Associate Data Engineer in SQL track (30 hours) prepares for it; the full Data Engineer level adds the Data Engineer in Python track.

Both certifications stay valid for 2 years, then you retake or upgrade to the full Data Scientist or Data Engineer level. Data Manipulation with pandas, a core course on the data scientist path, can be taken with DataCamp's AI tutor.

2. Udacity

Udacity sells Nanodegrees whose project submissions are reviewed by industry professionals, with a program certificate on graduation. The Data Scientist Nanodegree is advanced and runs 61 hours; Data Engineering with AWS is intermediate and runs 66 hours.

• Cost: Monthly subscription: $249/month; 4-month bundle: $846
• Format: Project-based Nanodegree programs and courses with human-reviewed projects and mentor support
• Certification: Program certificate on graduation; project submissions are reviewed by industry professionals

Trade-off: At $249 per month, Udacity costs several times a course subscription, and the Data Scientist Nanodegree expects you to arrive with the basics already in place.

3. Coursera

Coursera hosts the IBM Data Science Professional Certificate, a 12-course series that takes about 4 months at 10 hours a week and needs no prior experience. The IBM Data Engineering Professional Certificate runs 16 courses over about 6 months, and both include portfolio projects.

• Cost: Coursera Plus (monthly): $59/month; Coursera Plus (annual): $399/year; Single learning program: $49–$79/month
• Format: Video courses from universities and companies, with graded assessments, Guided Projects and hands-on labs
• Certification: IBM Professional Certificates: completion credentials earned by finishing the course series, not a proctored exam

Trade-off: Coursera's IBM certificates are earned by finishing the course series, not by passing a proctored exam, so they show completion more than skill under test conditions.

Our pick: DataCamp, for data scientist and data engineer certifications that end in a practical exam, starting with Associate Data Scientist in Python or Associate Data Engineer in SQL.

Best Platform for an AI Engineering Certification

DataCamp is the best platform for an AI engineering certification as a career switcher because it offers 2 associate-level AI engineer certifications, each with a practical exam. Udacity's Generative AI Nanodegree is a more expensive alternative for reviewed projects.

1. DataCamp

The AI Engineer for Data Scientists Associate certification is for learners who already work in Python and data, prepared by the Associate AI Engineer for Data Scientists track (40 hours). Developers moving into AI take the AI Engineer for Developers Associate certification after the Associate AI Engineer for Developers track (29 hours).

Each pairs a 2-hour timed exam with a practical exam and stays valid for 2 years. Career switchers who will use AI rather than build it can start with the AI Fundamentals track and its certification, which does not expire.

2. Udacity

Udacity's Generative AI Nanodegree is an intermediate program of 56 hours, with each project reviewed before you graduate. It suits learners who want written feedback on what they build.

Trade-off: The same $249 monthly price applies, and the program certificate is Udacity's own rather than an exam-based certification.

Our pick: DataCamp, for an AI engineering certification with a practical exam: Associate AI Engineer for Developers for developers, Associate AI Engineer for Data Scientists for data scientists.

Best Platform to Prepare for Foundational AWS, Azure, and Google Cloud Certifications

DataCamp is the best platform to prepare for foundational AWS, Azure, and Google Cloud certifications as a career switcher because one subscription covers prep tracks for all 3. The vendors' own academies add official practice exams and live cloud labs for the one cloud you choose.

Should an aspiring cloud data engineer specialize in one cloud or learn several? Pick the cloud your target employers use for your first associate-level exam; a foundational exam in a second cloud is a cheap addition later, but splitting your first months across 3 clouds delays the credential that gets interviews. DataCamp's guide to the best cloud certifications covers each exam in detail.

1. DataCamp

DataCamp's AWS Cloud Practitioner (CLF-C02) track (10 hours) is a collaborative effort between DataCamp and AWS, and the Microsoft Azure Fundamentals (AZ-900) track (9 hours) earns a 50% discount voucher for the AZ-900 exam. For Google Cloud, the Google Cloud Digital Leader, Google Associate Cloud Engineer, and Google Cloud Data Engineer tracks were created by Google Cloud and are offered on DataCamp.

2. AWS Skill Builder

AWS Skill Builder runs AWS's own 4-step exam prep plans, and its subscription adds the official pretests and practice exams. The Cloud Practitioner exam costs US$100, takes 90 minutes, and is a starting point for people with no prior IT or cloud experience.

• Cost: Free; Individual subscription (monthly): $29/month; Individual subscription (annual): $449/year; Exams: Cloud Practitioner US$100, Data Engineer Associate US$150
• Format: Self-paced courses, labs, game-based learning
• Certification: Official prep for AWS exams: Cloud Practitioner (90 minutes) and Data Engineer Associate (130 minutes), each valid for 3 years

Trade-off: It covers AWS only, and AWS recommends 2 to 3 years of data engineering experience before its Data Engineer Associate exam, so it is a second step for most career switchers.

3. Google Skills

Google Skills has the learning paths Google links from its exam pages, with labs in a real Google Cloud console. The Cloud Digital Leader exam costs $99, takes 90 minutes, has no prerequisites, and stays valid for 3 years.

• Cost: Starter: Free; Pro: $29/month; Exams: Cloud Digital Leader US$99, Professional Data Engineer US$200
• Format: Self-paced courses and hands-on labs
• Certification: Learning paths for Google Cloud exams: Cloud Digital Leader (90 minutes, valid 3 years) and Professional Data Engineer (2 hours, valid 2 years)

Trade-off: It covers Google Cloud only, and Google recommends 3 or more years of industry experience before the Professional Data Engineer exam.

4. Microsoft Learn

Microsoft Learn's free AZ-900 path ends in a 45-minute proctored exam, and passing it may earn ACE college credit. It is the lowest-cost way to put a first cloud credential on a resume.

Trade-off: AZ-900 is a fundamentals exam, so it opens conversations about Azure roles rather than proving you can build on Azure.

Our pick: DataCamp, for preparing for AWS, Azure, and Google Cloud exams in one place, starting with AWS Cloud Practitioner (CLF-C02) or Microsoft Azure Fundamentals (AZ-900).

How to Choose the Right Data Certification Platform

The right platform depends on the role you are switching into, your budget, and whether your target employer names a vendor credential.

Final Thoughts

DataCamp is the strongest starting point for a career switcher who wants a data or AI certification that proves skill because its role certifications end in a practical exam and the prep and exams share one subscription. For a first job, pair one of those certifications with the vendor exam your target employer names, such as PL-300 or AWS Cloud Practitioner.

If you only want IBM's name on a certificate and are fine with video-based learning, Coursera is a valid choice, and if you want a person to review every project (and have the budget for it), Udacity is. Otherwise, start the Associate Data Analyst in SQL track this week and book the Data Analyst Associate exam when the track is done.
