I took the ACP-120 (Jira Administrator) back in March and scored 68% on my first try – just under the 70% passing threshold. I'd been studying about 1.5 hours a day for 4 weeks, but I was spending way too much time on the admin UI and not enough on the conceptual stuff like permission schemes and workflow validators.
Second attempt I switched to 3 hours a day for 3 weeks with a heavy focus on practice questions. The areas I was weakest on were project roles versus groups and how notification schemes interact with service desk configurations. If you don't have hands-on Jira admin experience, spin up a free cloud instance and actually configure things yourself – reading about it isn't the same.
The exam is 75 questions in 120 minutes and it moves faster than you'd expect. Most questions are scenario-based: they describe a situation and ask what you'd configure. The answer that solves the problem with the least complexity is almost always correct. Don't overthink it.
I ended up passing with 76% the second time. The cert seems to carry real weight for Atlassian admin and DevOps-adjacent roles – my offer went up about 12% after listing it, though I can't attribute all of that to the cert alone.
I'm currently studying for ACP-600 and the content overlap with ACP-120 is maybe 30%. Different enough that it really needs its own dedicated prep cycle. Aiming for above 75% this time around.
Worth noting the exam format shifted a while back – it's much more scenario-based now and less focused on what a specific setting does. If you're using older study materials the question style won't match what you'll actually see. Stick to recent prep resources.
The permission schemes section is genuinely confusing until it clicks. I drew out diagrams on paper showing how groups, project roles, and global permissions stack on top of each other. Took about a week before it made sense, but once it did those questions became the easy ones on the exam.
I passed ACP-120 with 78% on my first try after 5 weeks of focused prep. The official Atlassian documentation is actually solid study material – better than most third-party guides I found online. Hands-on practice in a real instance made the biggest difference for me.
