The Certified Extended Reality Engineer (CXRE) is an advanced, vendor-neutral certification for the people engineering XR across AR, VR and MR. It validates that you understand XR foundations and hardware, can build 3D graphics and rendering, can design interaction and input, can develop in game engines, can optimize for performance, and can ship comfortable, accessible experiences to the store. The exam is computer adaptive and performance-based, and the credential is kept current through continuing education.
| Level | Advanced. It assumes hands-on XR, 3D or game development experience and validates production-grade XR engineering. |
|---|---|
| Delivery model | Computer adaptive, three stages. Your score on each stage selects the difficulty of the next, so no two candidates sit the same paper. |
| Format | 120 questions. A performance-based exam that includes performance-based questions and multiple-choice questions. Concepts transfer across every XR engine and headset. |
| Time | 180 minutes for the whole exam, timed. Autosaves every answer. |
| Scoring | You need a score of 700 out of 900 to pass. Results are reported on a scale of 100 to 900, and 700 corresponds to answering 72% of the exam correctly. Harder questions carry more weight, so a score means the same thing on any route. Multiple-response items and PBQs are all or nothing. |
| Retakes | No waiting period after a failed first attempt. Every attempt is paid for at the exam price. See the CertLabz Certification Retake Policy. |
| Voucher validity | 12 months from purchase, for one sitting. |
| Certification validity | 3 years. Renew with 75 CEUs per cycle and the $55 annual CE fee, or pass the current exam. Renewal details. |
| Language | English. |
| Credential | PDF certificate with QR code, public verification page, LinkedIn-ready credential ID. Issuer: CertLabz Certification Board. |
| Free resources | The exam objectives PDF and the ten sample questions PDF. |

A signed, verifiable:
The CXRE is a performance-based exam: it includes performance-based questions alongside multiple-choice questions. Instead of only picking A, B, C or D, you match features to their use, order a build task, fix a graphics or interaction problem, and choose the right approach. It is computer adaptive, is proctored and timed, needs no mandatory course, and tests engineering XR rather than reciting one engine's menus.
AR, VR and MR, XR hardware, 3D graphics, rendering and the frame budget.
Controllers, hands, gaze, raycasting, grabbing, locomotion and haptics.
Game engines, scenes, SDKs, spatial anchors, multiplayer and deployment.
Frame rate, batching, culling, profiling, comfort, accessibility and store submission.
XR is moving from labs into training, design, healthcare and field work, and skilled XR engineers are increasingly in demand across every industry. Every route is shown here at once, so nothing is hidden behind a control you have to find.

Every form is drawn from a bank of more than 130 items to these exact weights, whichever adaptive route you take. Filter by the area you want to study.
The exam runs in three stages. Your score on each stage selects the difficulty of the next, so a strong candidate is stretched and a struggling one is measured fairly rather than swamped. No two candidates sit the same paper. Harder questions carry more weight, so a scaled score means the same thing whichever route you took.
Each exam can have up to 5 to 12 performance-based questions, drawn fresh on every attempt, alongside the multiple-choice questions. A PBQ is a task rather than a list: you match features to their use, order a build task, fix a graphics or interaction problem, or choose the right approach. They are scored all or nothing, so partial guesses do not pass.
The CXRE is vendor neutral and describes XR engines and headsets generically, naming products only as examples. It tests the XR engineering judgement that transfers across engines and platforms.
Yes. Where a capability such as a shader, an SDK or a spatial anchor is involved, it is described by what it does, not tied to one product.
700 out of 900. Results are reported on a scale of 100 to 900, and 700 corresponds to answering 72% of the exam correctly.
There is no waiting period between a failed first attempt and a second attempt. Buy another voucher and sit the exam again when you are ready, and it will draw a fresh adaptive form from the bank. See the CertLabz Certification Retake Policy.
Yes, after three years. Keep it current by logging 75 CEUs during the cycle and paying the $55 annual CE fee before expiry, or by passing the current exam again.
The exam objectives PDF and the ten sample questions PDF. The CXRE Official Study Guide is a $50 ebook, included in two of the bundles. Hands-on practice comes with the All Access plan, included in the Complete bundle.
A laptop or desktop with a webcam and microphone, Chrome, Edge or Firefox, a stable connection, and a quiet private room for three hours. Phones and tablets are not supported.
CXRE is a continuing-education certification, like the CE credentials from CompTIA and ISC2. It is valid for three years from the day you pass. To keep it, log 75 continuing-education units during the cycle and pay the $55 annual CE fee before your expiry date. Or pass the current version of the exam again.
CEUs are logged from your CertLabz dashboard with supporting evidence. A certification that lapses can be reinstated only by passing the current exam.
