N.M. Admin. Code § 6.29.16.6
The department-approved Spanish language development standards provide companion piece to the New Mexico content standards for Spanish language arts (6.29.15 NMAC). The approved standards shall guide second-language instruction for PreK-12 Spanish language learner students. The Spanish language learner population falls into three basic categories: students whose primary or home language (L1) is Spanish; students from heritage language groups needing enrichment and further development of academic Spanish, some of whom maintain degrees of fluency in their heritage language; and any other students needing further development of academic Spanish. Because instruction must address the appropriate proficiency level of the individual student, which may vary greatly for any age, some consideration must be made for the student's maturity level.
