Joint Apprentice Training Committee of the Elevator Industry

Overview

The Joint Apprentice Training Committee of the Elevator Industry, an NCCRS member since 1988, was organized by Local #3 of the IBEW and the Association of Elevator Contractors of the metropolitan area of New York. Its purpose is to train apprentices who are hired by each of the 50 elevator repair, maintenance, and elevator modernization companies represented by Local #3 of the IBEW.

Each apprentice is required to attend the Elevator Apprentice School for a period of four years. Sudents must attend at least two classes each year. Each semester’s class offers 72 hours of theory, shop and/or laboratory experiences.

Courses are created to develop mechanical, technical, electronic, electrical, and solid state skills needed by technicians who maintain, repair, build, and install modernized and high tech elevator equipment in office buildings, apartment houses, hospitals, department stores, airports, parking garages, schools and many other types of buildings.

Students and admissions representatives please note: NCCRS does not provide transcripts. Transcript requests and inquiries should be directed to the organization offering the courses, examinations or apprenticeship. See the Source of Official Student Records in the sidebar near the top right side of this page.
