What is "NCTM"?  "National Certified Teacher of Music". 
These initials follow the names of some of the teachers in this directory.  These teachers have submitted papers on philosophy and  analysis of music; they have participated in local, state, and national committees, and shown leadership in music events. 

MTNA has developed a system of study that the applicant undertakes in order to be certified.  The system raises the likelihood that philosophy of teaching, methodology, and general competency in music are strengthened as part of the self-study and planning that this program entails.

Each teacher with "NCTM" continues to renew the certification each year through MTNA.
