National knows that there is a problem. National has some effort going into recruiting subject matter experts and having national level people train them correctly on the MB process. The issue is at the council and district level, and I believe that is because the MBC training is too brief, has no test, never expires, and far too many people are teaching MB and not even registered as an MBC.
National could fix this, I would propose a 3 step solution.
S1) Update MBC training, apply a test, training expires every 2 years.
S2) Tell councils that they cannot restrict the number of MB an MBC can teach, instead tell councils they can only restrict what is considered qualified to be an MBC.
S3) Force every district and council committee to have sitting and meeting MB committees.
