EX288 Meaning

What the Code EX288 Actually Means

If you searched for the meaning of EX288, here is the short answer: it is the exam code Red Hat uses for the Red Hat Certified Advanced Developer in Cloud-native Applications certification exam. Red Hat, Inc. is the governing body and administers the exam itself. The "EX" prefix in Red Hat's catalog marks a hands-on exam (as opposed to a "DO" prefix, which marks a training course), and "288" is the number paired with the developer-focused OpenShift curriculum.

That pairing is worth understanding because the numbers line up deliberately. The recommended training courses for this exam are DO180, DO188 and DO288, and the "288" in DO288 mirrors the "288" in EX288. When you see a course code and an exam code sharing digits at Red Hat, the course is the preparation and the exam is the performance test of the same skill area.

For deeper background on how the code is used across the ecosystem, our companion explainers cover what EX288 is, what EX288 stands for and what EX288 means from slightly different angles. This article focuses on decoding the code, the credential name and the exam objectives together.

The Name Change and Where EX288 Sits

Many candidates searching old forums will find EX288 described as the "Red Hat Certified Specialist in OpenShift Application Development" exam. That was the earlier title. Red Hat's skills framework update, effective May 11, 2026, renamed that credential to the current Red Hat Certified Advanced Developer in Cloud-native Applications. The exam code did not change; only the credential name and its place in the framework did.

This matters for two practical reasons. First, job postings and resumes written before the update may still use the older Specialist wording, so recruiters may use either term. Second, the renamed credential sits within a broader path. Red Hat also describes an Engineer in Cloud-native Applications path that requires both EX188 and EX288. That combined credential is a separate thing: passing EX288 alone earns the Advanced Developer credential, not the Engineer one.

Reading the Exam Format Behind the Code

The meaning of EX288 is inseparable from its format. This is a performance-based exam: you sit in front of a live Red Hat OpenShift environment for four hours and complete tasks that change the state of the cluster. There is no multiple-choice question bank to memorize. Red Hat has not publicly specified the exact number of tasks or how they split between scored and unscored items, so any figure you see quoted for task counts is not issuer-confirmed.

Scoring works on outcomes. Your final configurations are assessed against objective criteria, and Red Hat has not published a numeric passing threshold on the exam page or in the program guide. Claims of "210/300" or "300/500" circulating from third parties are not confirmed by Red Hat. We cover that gap in our passing score breakdown, and the same logic explains why aggregate pass rates are unavailable; see what the data actually shows on pass rates.

Relevant product documentation is supplied during the exam, and outside assistance is prohibited. That shapes preparation: you do not need to memorize every flag, but you must know where to look fast and which resource type answers which problem.

The 11 Objective Headings Decoded

Red Hat's exam page lists eleven top-level objective headings. These are objective headings, not percentage-weighted domains; Red Hat does not publish weights, so no domain can be called "the biggest." The full walkthrough lives in our EX288 exam domains guide. Here is what each heading means in practical terms.

Notice what the list says about the credential's identity: this is an application developer exam on OpenShift, not a cluster administration exam. The emphasis falls on building, configuring, troubleshooting and automating delivery of apps, which is exactly what the "Cloud-native Applications" in the title promises.

Why the OpenShift Version Matters

The current public exam page specifies OpenShift Container Platform 4.22 (accessed October 14, 2026). Red Hat does not publish a separately dated blueprint year, and multiple versions of an exam can coexist. That creates a trap worth knowing about:

• The current DO288 course page also says 4.22.
• The DO289 course-with-exam page still says 4.18.
• A public Udemy listing updated in August 2026 still states 4.18 and three hours.

Course and third-party versions do not override the exam you actually book. The four-hour duration comes from the current EX288 exam page; a third-party "three hours" figure is conflicting preparation metadata, and a training vendor's session hours are not exam timing. Confirm the version and duration on your booking confirmation, and practice on a cluster close to the version you will face. Our EX288 study guide explains how to set up a practice environment around this.

Booking, Fees and the Free Second Attempt

Red Hat administers its own proctored examinations through remote, individual testing-station and classroom options, subject to availability for the exact exam you want. No Pearson VUE or PSI appointment is verified for EX288, so do not look for it there.

The standard certification-exam list price in Red Hat's program guide is USD 500. Regional pricing and the real checkout amount may differ, so treat that figure as a reference point, not a guarantee. No member versus non-member price difference appears in the reviewed material. Red Hat's current policy also gives one free second attempt for an initially purchased paid exam, which meaningfully lowers the risk of a first-try miss. See the full EX288 cost breakdown and our scheduling guide for how availability works.

On eligibility: Red Hat recommends DO180, DO188 and DO288 and a review of the objectives, but no mandatory degree, fixed experience hours or EX188 prerequisite for sitting EX288 was verified. Recommended training is not a mandatory requirement. Details are in our requirements guide.

For remote delivery, you need compatible equipment and must meet the proctoring rules of your booked exam. Results are usually available within three US business days according to the exam page and reported as total scores, while the general program guide says within five business days with objective-area feedback. Red Hat does not provide item-level feedback, and that timing inconsistency is unresolved, so plan for the longer window.

Validity and Renewal in Plain Terms

The credential is current for three years. Renewal guidance has shifted with the May 2026 framework update. The updated FAQ describes renewing by retaking the highest-level exam, adding a certification at the same level, or advancing to a higher level. The program guide also supports retaking the original exam. A legacy renewal page still says Specialist credentials can only be renewed by retaking their respective exams and uses "non-current" rather than "expired" language. Where sources conflict, prefer the dated May 2026 material, and renew while the credential is still current. Retaking EX288 is the commonly verified route.

There is no EX288-specific CEU quota or CEU-only renewal route published. Do not confuse this with credit-based options that apply to higher Red Hat credentials.

Who Hires for This Skill Set

An EX288 holder is evidence of hands-on OpenShift application delivery skill. Roles that tend to value it include OpenShift application developers, platform and DevOps engineers who deploy onto OpenShift, integration and middleware developers, and consultants at Red Hat partners and enterprise integrators who build on the platform. Because the exam tests performance rather than recall, hiring managers often read it as proof you can build and debug in a live environment. Salary outcomes vary widely by region and seniority and are not published by Red Hat, so we discuss them qualitatively in the salary guide and look at openings in EX288 jobs.

Sequencing Your Preparation Around the Domains

Because the exam is hands-on, preparation should be lab time on a real cluster, ordered by dependency. Here is one sequence that follows how the objectives build on each other.
