The Role of Professional Certifications in Computer Occupations

Before presenting employer certification-demand findings, it is necessary to describe the methodology in order to assist in interpreting the results. The certification-demand analysis was performed using the Economic Modeling Specialists International (EMSI) dataset. To populate the dataset, EMSI combs through 100,000 websites, effectively capturing job listings for more than 1.5 million companies. The same job listings regularly appear on multiple websites. To reduce duplicates, EMSI uses a machine learning-based duplicate-detection process.
