experiences. Competency Assessments test the student over material outlined in the skills standards and taught using the curriculum materials.<br><br> When used with classroom performance evaluations, written competency assessments provide a means of measuring occupational readiness. Although each of these components satisfy a unique purpose in competency-based education, they work together to reinforce the skills and abilities students need to gain employment and succeed on the job. M EASURING SUCCESS Written competency assessments are used to evaluate student performance.<br><br> Results reports communicate competency assessment scores to students and provide a breakdown of assessment results by duty area. The results breakdown shows how well the student has mastered skills needed to perform major job functions and identifies areas of job responsibility that may require additional instruction and/or training. Group analysis of student results also provides feedback to instructors seeking to improve the effectiveness of career and technology training.<br><br> Performance patterns in individual duties indicate opportunities to evaluate training methods and customize instruction.

The format and duty titles were revised to conform to the model utilized for other skills standards within the Oklahoma Department of Career and Technology Education system. Additionally, the numbering of tasks in duties with multiple sections reflects a continuation of the numbering from previous sections in that duty.<br><br> This was done to accommodate the test-bank computer software being utilized for competency tests. The NATEF task list was reviewed and updated in January 2004. A national committee was assembled in Portland, Oregon to review the standards used in the Medium/Heavy Truck certification program.<br><br> The committee consisted of individuals representing the major truck manufacturers, truck repair shop owners and technicians, truck instructors and trainers, and truck equipment and parts suppliers. The committee reviewed the standards, task list, tools and equipment list, program hours, and instructor qualifications. The committee also had the most current National Institute for Automotive Service Excellence (ASE) truck task lists for reference purposes.<br><br> All the tasks are assigned a priority number: P-1, P-2, or P-3. These priority numbers pertain to requirements for instruction on tasks as follows: P-1: 95% must be taught in the curriculum. P-2: 70% must be taught in the curriculum.<br><br> P-3: 25% must be taught in the curriculum. Theory instruction and hands-on performance of all the basic tasks will provide initial training for entry-level employment in the Medium/Heavy Truck service field or further training in any or all of the specialty areas. Competency in these tasks will indicate to employers that the graduate is skilled in that area.<br><br> 1. It is assumed that: " in all areas, appropriate theory, safety, and support instruction will be required in the performance of each task; " this instruction includes identification and use of the appropriate tools and testing and measurement equipment required to accomplish certain tasks; " the student has received the necessary training to locate and use current reference and training materials from accepted industry resources (paper and electronic format). 2.<br><br> It is assumed that: " all diagnostic and repair tasks described in this document will be accomplished and verified in accordance with manufacturers 9 recommended procedures. 3. It is assumed that: " individual training programs being evaluated for certification will have written and detailed performance standards for each task covered and taught in the curriculum; " the learning progress of students will be monitored and evaluated against these performance standards; " a system is in place which informs all students of their individual progress through all phases of the training program.<br><br> 4. It is assumed that: " individual courses of study will differ across medium/heavy truck technician training programs; " development of appropriated learning delivery systems and tests which monitor student progress will be the responsibility of the individual training program. 5.<br><br> It is assumed that: " all students will receive instruction in the storage, handling, and use of Hazardous Materials in accordance with Hazard Communication Title 29, Code of Federal Regulation Part 1910.1200, the 8Right to Know Law 9, and state and local requirements; " hazardous and toxic materials will be handled, removed, and recycled or disposed of according to federal, state, and local regulations. 6. It is assumed that: " any tool requiring calibration will be calibrated according to the manufacturer 9s specifications periodically or as needed.<br><br> 7. It is assumed that: " students are given instruction in communication techniques with the customer. 8.<br><br> It is assumed that: " all students will be instructed in and will practice recommended precautions when handling electro-static sensitive devices. For every skill listed within the medium/heavy truck maintenance skills standards list, the following safety requirements must be strictly enforced: Comply with personal and environmental safety practices associated with clothing; eye protection; hand tools; power equipment; proper ventilation; and the handling, storage, and disposal of chemicals/materials in accordance with local, state, and federal safety and environmental regulations. * P = Priority Rating -------------------------------------------------------------------------------------------- For further information concerning NATEF, please contact them at: www.natef.org National Automotive Technicians Education Foundation 101 Blue Seal Drive, Suite 101 · Leesburg, Virginia 20175 (703) 669-6650 Fax: (703) 669-6125 OD32153: Electrical Systems Repair Tech 1 MEDIUM/ HEAVY TRUCK MAINTENANCE ELECTRICAL/ ELECTRONIC SYSTEMS REPAIR TECHNICIAN SKILLS STANDARDS Priority Ratings Duty A: General Electrical Systems Diagnosis Duty B: Battery Diagnosis and Repair Duty C: Starting System Diagnosis and Repair Duty D: Charging System Diagnosis and Repair Duty E: Lighting Systems Diagnosis and Repair Duty F: Gauges and Warning Devices Diagnosis and Repair Duty G: Related Electrical Systems DUTY A: General Electrical Systems Diagnosis CODE TASK Priority A.01 Read, interpret, and diagnose electrical/electronic circuits using wiring diagrams P-1 A.02 Check continuity in electrical/electronic circuits using appropriate test equipment P-1 A.03 Check applied voltages, circuit voltages, and voltage drops in electrical/electronic circuits using a digital multimeter (DMM) P-1 A.04 Check current flow in electrical/electronic circuits and components using a digital multimeter (DMM) or clamp-on ammeter P-1 A.05 Check resistance in electrical/electronic circuits and components using a digital multimeter (DMM) P-1 A.06 Find shorts, grounds, and opens in electrical/electronic circuits P-1 A.07 Diagnose parasitic (key-off) battery drain problems P-1 A.08 Inspect and test fusible links, circuit breakers, relays, solenoids, and fuses;
