The traditional route to certification in the New Mexico Teacher Licensure System incorporates three levels of licensure: provisional (Level 1), professional (Level 2), and master teacher (Level 3A). Movement from one level to the next and licensure renewal at Levels 2 and 3A are dependent upon the successful demonstration of the mandates set forth by the New Mexico Public Education Department (PED). Beginning July 1, 2004, in order to advance to the next licensure level, either from Level 1 to Level 2, or Level 2 to Level 3A, teachers must demonstrate how they are meeting the increased competencies for the next licensure level by submitting a Professional Development Dossier (PDD) to the PED. The majority of world language teachers typically pursue a Middle Level (5-9), Secondary (7-12), or a PreK-12 Specialty type of the teaching licenses available in NM with a core subject endorsement for a specific world language. These types of licenses authorize an individual to teach in a departmentalized setting and follow the 3-tier system. For additional information about certification, please, consult the New Mexico Professional Licensure Bureau.
