What Is EX288 Certification?

What EX288 Actually Is

EX288 is the exam code for the Red Hat Certified Advanced Developer in Cloud-native Applications credential, issued by Red Hat, Inc. If you have seen the same four characters attached to other credentials elsewhere, set those aside: on this site and in this article, EX288 refers only to the Red Hat OpenShift application-development exam. Everything below applies to that exam alone.

The credential targets developers who build, deploy and troubleshoot containerized applications on Red Hat OpenShift Container Platform. It is not a theory test. You are placed in front of a live OpenShift cluster, handed a set of tasks, and judged on whether the resulting configuration works. If you want a plain-language definition first, our short explainers on what EX288 is and what EX288 stands for cover the basics, and the EX288 certification overview gives the wider picture.

The 2026 Renaming and Where EX288 Sits

Red Hat's skills-framework update, effective May 11, 2026, renamed the former Specialist in OpenShift Application Development credential to the current title, Red Hat Certified Advanced Developer in Cloud-native Applications. If you encounter older job postings, forum threads or course notes using the Specialist wording, they are describing the predecessor name of this same exam track.

There is also a related but separate credential path: the Engineer in Cloud-native Applications, which requires passing both EX188 and EX288. Passing EX288 alone earns the Advanced Developer credential; it does not by itself deliver the combined Engineer credential. Keep that distinction in mind when reading career-path material, because the two are easy to conflate.

How the Exam Works: Format, Timing and Delivery

The current EX288 page specifies a four-hour exam. Content is performance-based work on a live Red Hat OpenShift environment. Red Hat does not publicly specify an exact task count or a scored versus unscored breakdown, so any number you see quoted elsewhere is not issuer-confirmed.

Red Hat administers its own examinations. Delivery options include proctored remote exams, individual testing stations and classroom sessions, subject to availability for the exact exam you want to book. Remote delivery requires compatible equipment and proctoring under the booked exam's technical rules, so check those before exam day rather than during check-in.

Rules that shape how you work

• Documentation is supplied. Relevant product documentation is available during the exam; outside assistance is prohibited.
• Persistence matters. Configurations and services must persist through the normal platform lifecycle without intervention. A deployment that works only because of a manual step you forgot to encode is a failure.
• The end state is graded. Successful final configurations are assessed against objective criteria, which rewards candidates who verify their own work before moving on.

The 11 Objective Areas, Explained

Red Hat's exam page lists 11 top-level objective headings. These are objective headings, not percentage-weighted domains; Red Hat does not publish official weights or a highest-weighted area. The breakdown below uses the issuer's headings and describes the kind of work each implies. For a deeper treatment, read the complete guide to all 11 content areas.

Registration, Fees and the Free Second Attempt

Red Hat's certification program guide lists a USD 500 standard list price for certification exams. Regional pricing and the actual EX288 checkout may differ, and that figure was not independently retrieved from a live checkout page, so confirm the price when you book. The reviewed issuer material publishes no member versus non-member price difference.

Under the current program policy, an initially purchased paid exam includes one free second attempt. That is a meaningful safety net for a four-hour practical exam where a single misconfiguration can cost you, but read the policy conditions at purchase time. For a fuller look at what you will spend including training, see the EX288 certification cost breakdown, and for scheduling mechanics see EX288 exam dates and scheduling.

Prerequisites and Recommended Preparation

The current exam page recommends three Red Hat courses, DO180, DO188 and DO288, along with a review of the exam objectives. Recommended is not required: no mandatory degree, fixed experience hours, reference count or EX188 prerequisite for sitting EX288 was verified. Our EX288 requirements guide goes deeper on eligibility.

One nuance worth flagging: DO288 is a preparation curriculum, not an exam blueprint. The objective headings on the exam page are the authoritative scope; course topics should not be used to add or remove items from that list. A practical way to prepare is to treat the course as a map of tooling and the exam objectives as the checklist you must be able to execute from memory.

• Review each of the 11 objective headings and write a one-line "I can do this without notes" statement for each.
• Practice on a real OpenShift environment so commands, console workflows and error messages are familiar.
• Rehearse working only from supplied documentation, since that is all you will have on exam day.

For a structured plan, work through the EX288 study guide and the EX288 training overview, and use the EX288 practice tests to check your readiness.

The OpenShift Version Question

The current public EX288 page specifies OpenShift Container Platform 4.22 (accessed October 14, 2026). No separately dated blueprint year is published. The DO288 course page also references 4.22, but the DO289 course-with-exam page still lists 4.18, so Red Hat's own course pages are not perfectly aligned. Course versions do not override the exact exam version you book.

Third-party material adds further noise. A public Udemy listing updated August 2026 still states 4.18 and three hours, which conflicts with the four-hour duration on the Red Hat exam page. Treat third-party metadata as preparation commentary, not authority. Likewise, a training provider's course hours describe training sessions, not exam duration.

Scoring, Results and What Is Not Published

Red Hat assesses final configurations against objective criteria, and results are reported as total scores. A numeric passing threshold was not verified on the current exam page or program guide, and third-party claims such as 210/300 or 300/500 are not issuer-confirmed. If you want the full discussion, see our page on the EX288 passing score.

Likewise, no aggregate pass rate is published by Red Hat. Individual pass or fail stories and vendor guarantees do not establish a rate. Our EX288 pass rate analysis explains what can and cannot be concluded.

Results timing: an unresolved inconsistency

Red Hat's own documents differ slightly. The exam page says results are usually available within 3 US business days and reported as total scores; the general program guide says within 5 business days with objective-area feedback. Neither provides individual exam-item feedback. Plan around the longer window, and do not expect to see which specific tasks you missed.

Validity and Renewal

The credential is current for 3 years. Red Hat's updated May 2026 FAQ describes renewal by retaking the highest-level exam, adding a certification at the same level, or advancing to a higher level within its framework, and the program guide also supports retaking the original exam to renew. Retaking EX288 is the commonly verified route.

Be aware of a source conflict: Red Hat's legacy renewal landing page still says Specialist credentials can only be renewed by retaking their respective exams and uses "non-current" rather than "expiration" language, while the newer guide uses expiration wording. The dated May 2026 framework and FAQ should be preferred for the updated policy. No EX288-specific CEU quota or CEU-only renewal route is published. Renew while your credential is still current and check your transcript and the applicable rules.

Who Benefits From This Credential

EX288 maps most naturally to roles where you build and ship applications onto OpenShift rather than administer the cluster itself. Typical fits include application and platform developers, DevOps and release engineers who own build and deployment pipelines, and consultants who deliver containerized workloads for clients running Red Hat OpenShift. Organizations standardized on Red Hat's container platform are the most likely to value it, because the exam exercises the specific tooling they use day to day: image streams, S2I builds, templates, Pipelines and Operator-backed services.

Hiring demand and pay vary widely by region, seniority and employer, and no verified compensation figures are tied to this credential here. For discussion of the career side, see our pieces on EX288 jobs, the EX288 salary guide and whether the EX288 certification is worth it.

Sequencing Your Preparation Around the Objectives

Rather than generic scheduling advice, order your practice by dependency. Later objectives lean on earlier ones, so skills compound when you build in this order.

Troubleshooting sits last here only because it is easiest to practice once you can build everything else; keep revisiting it throughout, since failures can appear inside any task. Finish with timed, full-length runs so four hours of continuous hands-on work feels familiar. Many candidates also keep a personal EX288 cheat sheet of commands and object patterns for fast review before sitting the exam.
