Cost segregation certification pathway

NBCSS is a professional membership organization. Certification pathways are available to eligible members: join, then pursue the pathway that fits your experience. Instruction is member-only; there is no public course enrollment, and NBCSS makes no claim of regulatory approval or exemption.

Membership classes

• Practitioner Candidate Member — an approved individual preparing for professional practice, with access to the member training pathway (the 14-course, 140-hour Practitioner Program).
• Professional Member — an experienced practitioner admitted through the professional-member application and work-history review, who may pursue the certification challenge route when otherwise eligible.

How to become a cost segregation professional through NBCSS

1. Apply for membership on one of two paths (experienced professional, or candidate taking the Practitioner Program). You submit payment information with the application and are charged only if approved.
2. Membership approval, then activation.
3. As an active member: Practitioner Program instruction (Candidate class) or the experienced-practitioner assessment route (Professional class).
4. Assessments — knowledge exam, practical, oral defense — evaluated by qualified reviewers.
5. Certification decision by a human decision-maker. Payment, membership approval and course completion never award a credential.
