Professional Technician Development Committee Information Report: 2010-1: The Matriculation Process: A Proven Pathway for New Technician Success in the Workplace

Most fleets use a thoughtful approach in the hiring of technicians. However, many of these same companies take a minimalist approach to matriculation. This can lead to poor performance, unacceptable conduct issues and poor employee retention. The purpose of this document is to help fleet managers ensure that all newly hired graduates of technical trade schools make a successful transition to the next level of their career objectives.


The purpose of this Recommended Practice (RP) is to provide information for judging the performance of aftermarket brake linings on air-actuated foundation brakes, including testing in accordance with the dynamometer test procedure in Federal Motor Vehicle Safety Standard (FMVSS) 121 and lining supplierqualification information. Such information will assist fleet operators in choosing aftermarket brake liningsthat will perform adequately on typical combination (tractor/trailer) vehicles and single trucks.
