What EX288 Actually Is (and Isn't)
EX288 is the exam code for the Red Hat Certified Advanced Developer in Cloud-native Applications credential, administered by Red Hat, Inc. Under Red Hat's May 11, 2026 framework update, this credential carries the title formerly known as Specialist in OpenShift Application Development. If you have seen older material that refers to the "OpenShift Application Developer" exam, it is the same exam family under its previous name.
It is also important to know what EX288 is not. Red Hat's separate Engineer in Cloud-native Applications path requires both EX188 and EX288. That combined credential is a different scope from this article. EX288 is a standalone exam, and the requirements discussed here apply to sitting EX288 itself. If you are still orienting yourself, our explainer What Is EX288 Certification? covers the naming and positioning in more detail.
Formal Eligibility: What Red Hat Requires
The honest answer to "what are the EX288 requirements?" is that the formal barrier to entry is low. In the reviewed Red Hat material, none of the following was verified as a condition of sitting EX288:
- A college degree or any academic credential
- A fixed number of years or hours of work experience
- A minimum number of professional references
- Prior completion of EX188 or any other certification exam
- Mandatory completion of a paid training course
In other words, you do not apply for EX288 and wait for approval. You purchase an exam booking, choose a delivery option, and show up prepared. That said, a low formal bar does not mean a low practical bar. The exam is performance-based, and candidates who lack real OpenShift hands-on time tend to find it demanding. Our EX288 difficulty guide unpacks why.
Recommended Preparation: DO180, DO188 and DO288
Red Hat's current EX288 exam page recommends three courses and a review of the exam objectives: DO180, DO188 and DO288. These are recommendations, not entry requirements. Many working OpenShift developers qualify through project experience and self-directed lab time rather than a formal class sequence.
| Item | Status for EX288 | What it means for you |
|---|---|---|
| DO180 | Recommended | Useful foundation if containers and basic OpenShift usage are new to you |
| DO188 | Recommended | Useful for container development fundamentals before moving to cluster-focused work |
| DO288 | Recommended | The most directly aligned preparation course for application building and deployment |
| EX188 | Not verified as a prerequisite | Required only for the separate Engineer in Cloud-native Applications path, not to sit EX288 |
| Degree / experience hours | Not verified as required | No fixed threshold published in the reviewed material |
One caution: DO288 is a preparation curriculum, not an exam blueprint. The exam objectives published on Red Hat's EX288 page are the authoritative scope. Use courses to build skill, but measure your readiness against the objectives. For a structured approach, see our EX288 study guide and the overview of EX288 training options.
The OpenShift Version Trap
The single most overlooked "requirement" is version alignment. The current public EX288 exam page specifies OpenShift Container Platform 4.22 (accessed October 14, 2026), and the DO288 course page also states 4.22. But the picture is not uniformly consistent across Red Hat's own properties:
- The DO289 course-with-exam page still states 4.18.
- A public Udemy listing updated August 2026 also references 4.18 and a three-hour duration, which conflicts with Red Hat's four-hour exam page.
- Multiple exam versions can coexist, and the version-specific objectives linked from the exam page were not retrieved for this article.
Practically, differences between adjacent OpenShift releases are often modest for an application developer, but console layouts, defaults and available features can shift. Practice on a cluster close to your booked version whenever you can.
Format, Fee and Booking Mechanics
Understanding the logistics is part of qualifying, because they shape how you prepare.
Format and timing
EX288 consists of hands-on performance tasks completed on a live Red Hat OpenShift environment. It is not a multiple-choice question bank. The current exam page lists a duration of 4 hours. Red Hat does not publicly specify the exact task count or the scored/unscored breakdown, so avoid any source claiming a precise number of questions.
Your work is assessed against objective criteria applied to your final configurations. Relevant product documentation is supplied during the exam, outside assistance is prohibited, and your configurations and services must persist through the normal platform lifecycle without manual intervention. That last point matters: an application that works only until a pod restarts will not earn credit.
Fee and retake
The Red Hat Certification program guide lists a standard certification-exam list price of USD 500. Regional pricing and the actual EX288 checkout may differ, and no member versus non-member price difference is published in the reviewed issuer material. Under current program policy, one free second attempt is available for an initially purchased paid exam. Our EX288 certification cost breakdown covers budgeting in depth.
Delivery and scheduling
Red Hat administers its own proctored examinations: remote, individual testing-station and classroom options, subject to availability for the exact exam you want. No Pearson VUE or PSI appointment was verified for EX288. Remote delivery requires compatible equipment and proctoring under the booked examination's technical rules, so test your setup well before exam day. For scheduling specifics, see EX288 exam dates and scheduling.
Scoring and results
A numeric passing threshold was not verified on the exam page or in the program guide. Figures like 210/300 or 300/500 that appear on third-party sites are not issuer-confirmed. Results timing is described inconsistently: the exam page says usually within 3 US business days with a total score, while the program guide says within 5 business days with objective-area feedback. Neither provides item-level feedback. Details are collected in our EX288 passing score article and pass rate discussion.
Skills You Need Before You Book
Because there is no formal skill gate, you must self-assess against the eleven objective areas Red Hat publishes. These are the top-level headings from the current exam page, not percentage-weighted domains; Red Hat publishes no official weights. Below is what "ready" looks like in practice for the areas that most often trip candidates. For a full walkthrough of all eleven, read our EX288 exam domains guide.
Domains 1 and 2: Work with Red Hat OpenShift Container Platform; Deploy multi-container applications
You should navigate the CLI and web console fluently and deploy applications composed of several cooperating containers.
- Create and manage projects, deployments, services and routes without hunting for syntax
- Wire multi-container applications together so they communicate and survive restarts
- Verify your work by inspecting resources, not by assuming success
Domains 3, 5 and 7: Container images, image streams and source-to-image (S2I)
These areas cover how code becomes a running image inside OpenShift.
- Work with container images in the platform, including how builds consume and produce them
- Understand image streams and how they track image references and updates
- Use the S2I framework to build application images from source
Domains 4 and 8: Troubleshoot builds and deployments; build hooks and build triggers
Troubleshooting is where hands-on experience pays off most, because the exam environment rewards the ability to diagnose a broken build or deployment quickly.
- Read build and deployment logs and events to locate the real failure
- Configure build hooks and triggers so builds run when they should
- Recognize common causes: bad image references, missing resources, misconfigured triggers
Domains 6, 9, 10 and 11: Configuration maps and secrets; templates; OpenShift Pipelines; Operators
These cover externalizing configuration, reusable application definitions, automation, and consuming Operator-provided services.
- Inject configuration and sensitive values into applications through config maps and secrets
- Build and instantiate templates with parameters
- Create and run OpenShift Pipelines for build and deploy automation
- Work with Operators accessible for users to run in their applications
Key Takeaway
Convert the eleven objective headings into a personal checklist and mark each one only when you can complete a realistic task from scratch, against the clock, using only documentation available inside the cluster. Reading about a topic does not count.
A Domain-Ordered Plan to Qualify
Since qualifying really means becoming ready, here is one way to sequence the objective areas. The ordering follows dependency: later topics assume earlier ones. Adjust the pacing to your experience. For a fuller method, see the complete study guide.
Platform and multi-container fundamentals
- Domain 1: CLI and console fluency on a cluster matching your booked version
- Domain 2: deploy and connect multi-container applications
Images, image streams and S2I
- Domains 3, 5 and 7: how images, image streams and S2I builds relate
- Practice building from source until the flow is automatic
Breaking and fixing
- Domains 4 and 8: deliberately break builds and deployments, then diagnose
- Configure hooks and triggers and confirm they fire
Configuration, templates, pipelines and Operators
- Domains 6, 9, 10 and 11: config maps, secrets, templates, pipelines, Operators
- Run full timed mock sessions of about four hours to build stamina
Troubleshooting (Domain 4) appears early in the middle of the plan on purpose: it cuts across every other area, so repeated practice at diagnosing failures pays dividends everywhere. When you want timed repetition, the EX288 practice tests can help you check whether your recall holds under pressure, and our EX288 cheat sheet is a handy final review.
After You Pass: Validity, Renewal and Next Paths
How long it lasts
The credential is current for 3 years. Red Hat's 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. Retaking EX288 is the common verified route. No EX288-specific continuing-education credit quota or credit-only renewal route is published, so do not assume one exists.
Career and pathway considerations
The credential is aimed at developers who build and deploy applications on OpenShift, which makes it relevant to platform-oriented development, DevOps-leaning engineering and cloud-native application teams. If you are weighing it against your goals, read whether EX288 is worth it, browse EX288-related jobs, and review the salary analysis. If you later pursue the Engineer in Cloud-native Applications path, remember it requires EX188 in addition to EX288.
Frequently Asked Questions
No EX188 prerequisite for sitting EX288 was verified. EX188 matters only for the separate Engineer in Cloud-native Applications path, which requires both EX188 and EX288.
No. Red Hat recommends DO180, DO188 and DO288, along with reviewing the exam objectives, but recommended training is not a mandatory eligibility requirement for EX288.
The current exam page lists 4 hours of hands-on performance tasks on a live Red Hat OpenShift environment. It is not multiple choice, and Red Hat does not publish an exact task count.
Red Hat's program guide lists a standard list price of USD 500 for certification exams, though regional pricing and actual checkout may differ. One free second attempt is available for an initially purchased paid exam.
The current public EX288 page specifies OpenShift Container Platform 4.22, but multiple versions can coexist and some related course pages still show 4.18. Confirm the version tied to your specific exam booking before you commit to a lab environment.
In short, qualifying for EX288 is less about meeting a checklist of formal prerequisites and more about proving to yourself that you can build, deploy and repair applications on OpenShift under time pressure. Confirm your exam version, work through the eleven objective areas with real labs, and book when your hands-on results are consistent.
