The Certified Digital Twin Engineer (CDTE) is a beginner, vendor-neutral certification for the people building digital twins of physical assets, systems and processes. It validates that you understand digital twin foundations and where they fit, can build models and run simulations, can integrate sensor and IoT data, can add analytics and visualization, can manage the twin across its lifecycle, and can secure and govern what you build. The exam is computer adaptive and performance-based, and the credential is kept current through continuing education.
| Level | Beginner. An entry credential: it establishes solid digital-twin fundamentals and assumes some hands-on exposure to simulation, IoT or engineering data. |
|---|---|
| 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 | 60 questions. A performance-based exam that includes performance-based questions and multiple-choice questions. Concepts transfer across every digital twin platform. |
| Time | 90 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 35 CEUs per cycle and the $25 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. |

A signed, verifiable:
The CDTE 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 capabilities to their use, order a modeling task, fix a data or synchronization problem, and choose the right approach. It is computer adaptive, is proctored and timed, needs no mandatory course, and tests building digital twins rather than reciting one product's menus.
What a digital twin is, twin types, physics-based and data-driven models, simulation and fidelity.
Sensor ingestion, IoT platforms, real-time streams, data mapping, APIs, connectors and synchronization.
Predictive models, anomaly detection, dashboards, 3D visualization and operational twins.
Access control, data protection, model governance, interoperability standards and compliance.
Digital twins are moving from research into everyday engineering, and skilled digital twin engineers are increasingly in demand across manufacturing, energy, infrastructure and beyond. Every route is shown here at once, so nothing is hidden behind a control you have to find.

Compiled September 2026 from Siemens SCE program pages. The Siemens credential is a vendor course certificate tied to one toolchain; the CDTE is vendor neutral, computer adaptive and performance-based for $99. Product names and trademarks belong to their owners; CertLabz is not affiliated. Confirm current details with each provider.
Six reasons this credential is worth your time, and worth an employer's attention.
One price for the exam, set by its level. Bundles add the study guide and hands-on practice at a saving.

Every form is drawn from a bank of more than 90 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 capabilities to their use, order a modeling task, fix a data or synchronization problem, or choose the right approach. They are scored all or nothing, so partial guesses do not pass.
The CDTE is vendor neutral and describes digital twin platforms generically, naming products only as examples. It tests the digital twin judgement that transfers across platforms.
Yes. Where a capability such as a connector or a simulation engine 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 35 CEUs during the cycle and paying the $25 annual CE fee before expiry, or by passing the current exam again.
The exam objectives PDF and the ten sample questions PDF. The CDTE 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 90 minutes. Phones and tablets are not supported.
CDTE 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 35 continuing-education units during the cycle and pay the $25 annual CE fee before your expiry date. Or pass the current version of the exam again. Earning a higher-level CertLabz certification renews it too, the way CompTIA certifications stack.
CEUs are logged from your CertLabz dashboard with supporting evidence. A certification that lapses can be reinstated only by passing the current exam.
