The three CompTIA certifications you mentioned—Data+, DataSys+, and DataX—cater to different levels of expertise and specializations within the data and IT fields:
CompTIA Data+: This is an entry-level certification aimed at individuals who want to start their careers in data analysis. It covers foundational skills such as data mining, visualization, governance, and statistical analysis. It's ideal for those seeking roles like data analysts or business analysts, as it focuses on using data to generate actionable insights and reports. Data+ is a good starting point for those new to the field, with about 18-24 months of relevant experience being recommended.
CompTIA DataSys+: This is a more advanced certification focused on data systems management. It covers topics such as database architecture, cloud integration, and data security. DataSys+ is geared towards professionals responsible for managing and securing data storage and processing systems. It's suitable for roles like database administrators, data architects, and IT security specialists, as it requires deeper expertise in managing data infrastructures.
CompTIA DataX: This is an expert-level certification for professionals with at least five years of experience in data science or related fields. DataX is part of the Xpert series and covers advanced concepts in mathematics, machine learning, and specialized data science applications. It targets seasoned professionals who want to validate their expertise in high-level data science operations. This certification is designed to demonstrate a comprehensive understanding of critical data science tools and concepts and is ideal for advanced roles such as data scientists.
In summary, Data+ is for foundational data skills, DataSys+ is for managing data systems, and DataX is for expert-level data science skills.
Both of those courses content are on the new platform. If you are listed as an instructor for your organization in the platform you should see the instructor material listed. If not, you just need to reach out to your CompTIA rep and they will activate it for you. Hope this helps.
