Jira is used by over 300,000 organizations worldwide — making Jira administration one of the most in-demand technical skills in enterprise IT. According to Glassdoor's May 2026 salary data, Atlassian Jira Administrators earn an average of $156,068 per year in the United States, with the range extending to $214,212 for senior roles.
Atlassian certifications are the formal validation of those administration skills. An Atlassian survey found that 73% of Atlassian-certified professionals reported increased job prospects after certification. The credentials cost $249 per exam — a modest investment relative to the salary outcomes they support.
But choosing the right certification requires understanding a key distinction: Data Center vs. Cloud. Atlassian has been aggressively migrating its customer base to Jira Cloud, and the certification program reflects that shift.
