New to the forum so here goes. I am currently 4th Dan Tang Soo Do and have a student who has been training for about 15 years with us. Coming close to advancing to 4th Dan. Complicating factors are he has Cerebral Palsy and is somewhat limited. Effort and attitude are great, but I/we are not sure he can truly instruct and demonstrate the finer points. Any others with similar experiences? Any advice or suggestions welcomed. Thanks in advance.
