About the NAASE Certified Sales Engineer Credential

The Certified Sales Engineer (CSE) credential is issued by the North American Association of Sales Engineers (NAASE) to professionals whose background has been reviewed for real-world sales engineering experience.

The CSE review process focuses on practical presales and technical sales activities such as discovery, product demonstrations, proposals, RFP/RFI support, proof-of-concept or pilot work, customer requirements, solution fit, product customization, and buyer enablement. The credential is vendor-neutral and applies across industries where technical products, services, or solutions are sold.

For the certified professional, CSE provides formal recognition of sales engineering experience and commitment to professional standards. For employers, customers, and partners, it offers a clear signal that the individual’s experience has been reviewed against core sales engineering responsibilities.

The CSE credential is awarded through an experience-based review of the credential holder’s sales engineering background and practice areas.
