Download Application Form:

To be certified as an MBB you (referred to as the candidate) must submit this “application & portfolio” detailing your professional accomplishments over the past five years. ISEL uses a certification board of Master Black Belts from across the United States who review each application, discuss and reach consensus to either “approve for certification’ or “do not certify at this time’. The entire process from submission through decision can take up to 45 days.

The identity of the certification board members is not made public to prevent the appearance of impropriety.

In addition to the above definition, ISEL requires other activities detailed in this application. Our certification is different from other certifications by requiring candidates to demonstrate an understanding of emotional intelligence and ability to relate to the workforce for sustainable improvements.

Being able to bring people together for lasting improvements is an MBB skill expected from employers and clients – thus ensuring a relevant certification.

When certified as a Master Black Belt you are authorized to add the distinctive “LSSMBB” signature block enhancer and potentially serve as a certification board member for other MBB candidates.

Phase 1: Candidate submits online certification portfolio and payment. The portfolio is reviewed for completeness by AALSSC Director of Certification. (7-day processing time) • If determined to be complete – the candidate is notified, and portfolio is sent to certification board. • If determined to be incomplete – the portfolio is returned to the candidate with recommendations.

Phase 2: Portfolio is received by certification board. Each board member reviews the portfolio and provides feedback with the recommendation. Board members meet, discuss and reach consensus for certification decision (up to 30 days processing time). Recommendations are reviewed by Director of Certification who records recommendations and archives portfolio package.

Phase 3: Director of Certification notifies the candidate of the decision. • If the board recommends certification: certificate package is generated and mailed to the candidate. • If a board does not recommend certification: the candidate is notified of the specific reason(s) and given the opportunity to appeal the decision.

Appeal Process:
The candidate has one year from notification to re-submit application with modifications. Additionally, a candidate can include a letter to board members explaining details as necessary. Once the application is re-submitted the process begins again (at no additional cost).
