SOLIDWORKS provides certifications covering different aspects of its functionality. As a user, you don't need to gain any of those certifications to use the software; however, they can prove your SOLIDWORKS skills. SOLIDWORKS certifications are a good means of showing employers or clients that you have mastery over a certain aspect of the software that would be required for a specific project. Certifications can be classified under four levels: associate, professional, professional advanced, and expert. Associate certifications represent the entry-level, expert certifications represent the highest level, and professional and professional advanced represent middle levels, respectively. The following section is a list of the certification levels provided by SOLIDWORKS. Note that SOLIDWORKS adds or removes certifications over time. You can check the SOLIDWORKS certification online catalog for more information.
