Course Description: This course will introduce students to the fundamentals of heavy
truck chassis used in diesel equipment technology.
Performance Descriptors (Level of Competence)
1 – Novice: the student does not demonstrate fundamental knowledge and
skills; performance is fragmented, incomplete and needs considerable
development and supervision.
2 – Partial Mastery: the student partially demonstrates fundamental knowledge
and skills; basic but inconsistent application; characterized by errors and
omissions; needs further development and supervision.
3 – Mastery: the student demonstrates fundamental knowledge and skills with
minimal supervision; work is accurate and complete; performance is solid.
4 – Above Mastery: the student demonstrates competent and proficient
performance; application of knowledge and skills is thorough and effective, and
the student can work independently.
5 – Distinguished: the student is self-directed and demonstrates exceptional
and exemplary performance; application of knowledge and skills is distinctive
and sophisticated and the student can solve problems independently.
