Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

91 Course Substitution Process and Alternative Courses This section provides a preliminary listing of possible alternative courses, and describes the conditions under which candidates seeking national instructor certification can apply these courses. The intent is to allow those candidates who have already received instruction that meets certain conditions to achieve certification, thereby avoiding duplication and saving time. The process also permits candidates to fast track the certification process by taking approved alternative courses in advance of those scheduled by the certification program. The flexibility is intended to give instructor candidates increased choices towards reaching certification without compromising the program’s validity. Note: The alternative courses listed below are preliminary; research continues to seek additional course offerings. A challenge facing the search effort is the limited number of “plug-and-play” courses that fully satisfy the duration and learning objectives established within this project. Many courses, for example, are part of larger educational programs where it is uncertain if the provider will make certain elements available a la carte. In other cases, some of the examples presented here are not fully developed course offerings but instead consist of reference materials or related work accomplished by competent organizations. The collective information provides the Panel and eventual program management with a preliminary indication of organizations with existing courses or that have the experience and ability to develop suitable courses. Course Substitution Process The Research Team proposes that any candidate seeking certification under this program may request that a non-program course be considered for substitution for one of the required certification courses using the following guidelines: • A substitute course must contain equal or greater contact hours as the certification course. • A substitute course must cover the same or greater content area as the certificate course as determined by course objectives. • A substitute course must have equal or greater academic rigor and complexity as the certificate course. • Evaluation of student mastery must be equal to or greater than that required in the certification course. • A student must present a certificate of completion, transcript or other official instrument documenting satisfactory participation and completion of the substitute course. • The capstone course will not be considered for substitution under any circumstances. • Acceptance of substitute courses does not in any way change the certification requirements of the capstone course and subsequent certification. A P P E N D I X A List of Alternative Courses

92 A National Training and Certification Program for Transit Vehicle Maintenance Instructors • A substitute course must have been complete no later than 5 years from the time the requested substitution is filed. • A fee may be applied to each requested course substitution, regardless of outcome. • No more than four (4) courses can be substituted for certification courses. An initial group of equivalent courses will be determined within the first year of the program and additional courses may be added later as required. The initial group of courses and each subsequent review for substitute course requests will be determined by the program’s eventual management team. It is envisioned that the course validation process will be conducted by a team of subject matter experts (SME’s) and instructional designers under the direction of the program management to assure conformity to both content and academic standards established for the certification process. Also, as part of the alternative course process, if someone has earned an associate degree in a related field, he/she may be able to substitute suitable courses obtained through that degree to meet certain National Instructor Certification requirements. The same team of SME’s and instructional designers will make these determinations under program management guidance. Alternative Courses As stated above, alternative courses will be selected and approved through a formal process developed by the program management team. The list of alternative courses provided here is by no means comprehensive nor is it intended as the only suitable alternative course listing available to the program. The Research Team also wants to be clear that final determination for the alternative courses will be made by the eventual program management. Mentoring and Coaching Mentoring and coaching courses need not be maintenance specific to be effective. Many of the attributes of a successful mentoring program apply regardless of the occupation. Although the program course will tailor its instruction specifically to a transit maintenance audience, several sources are available for developing these skills in a more generic manner. Potential alternative courses are listed first followed by reference material on mentoring.
