CLAD Practice Test – Certified LabVIEW Associate Developer (CLAD) Exam

The Certified LabVIEW Associate Developer (CLAD) certification from National Instruments (NI) is an entry-level credential for professionals developing and working with LabVIEW applications. NI describes the CLAD as demonstrating broad working knowledge of the LabVIEW environment, basic coding and documentation best practices, and the ability to read and interpret existing LabVIEW code.

The official CLAD examination is a multiple-choice exam with 40 questions and a 1-hour time limit. The official NI sample exam specifies a 70% passing grade, which means candidates should aim to answer at least 28 of 40 questions correctly.

NI's current CLAD page does not publish a universal current exam price because fees can depend on registration location and scheduling arrangements. Candidates should verify the applicable fee during the official registration process rather than relying on older published prices. Historical NI community information lists an older CLAD price, but that figure should not be treated as the current fee.

Certification Details

The official NI CLAD information confirms that the credential is entry level, has no formal prerequisite, is valid for two years, and can be taken online or at PSI testing centers.
