Secondary vocational-technical education programs in Mississippi are faced with many challenges resulting from sweeping educational reforms at the national and state levels. Schools and teachers are increasingly being held accountable for providing true learning activities to every student in the classroom. This accountability is measured through increased requirements for mastery and attainment of competency as documented through both formative and summative assessments. The courses in this document reflect the statutory requirements as found in Section 37-3-49, Mississippi Code of 1972, as amended (Section 37-3-46). In addition, this curriculum reflects guidelines imposed by federal and state mandates (Laws, 1988, ch. 487, Section 14; Laws, 1991, ch. 423, Section 1; Laws, 1992, ch. 519, Section 4 effective from and after July 1, 1992; Carl D. Perkins Vocational Education Act III, 1998; and No Child Left Behind Act of 2001). Heating and Air Conditioning is an instructional program designed to teach students to install, operate, test, repair, and maintain residential heating and air conditioning systems. Upon successful completion of the program, the student should be prepared for an entry level heating and air conditioning technician or related position and may pursue postsecondary education. This curriculum has been aligned to modules in the Contren Learning Series as endorsed by the National Center for Construction Education and Research (NCCER). Students who study this curriculum using the Contren Learning Series materials under the supervision of an instructor who has been certified by the NCCER are eligible to be tested on each module. Students who successfully pass these tests may be certified to the NCCER by the instructor and will receive documentation from NCCER. Appended are: (1) Contren Learning Series Best Practices; (2) Academic Standards; (3) Workplace Skills for the 21st Century; and (4) National Educational Technology Standards for Students. A list of suggested references is provided for each unit. (Contains 7 footnotes.)
