Methods of Evaluation of Competencies:

Evaluation of student mastery of course competencies will be accomplished using the following methods:

Competency completion level/ Lab Assignments	30-60% of grade 
Test and quizzes				20-50% of grade 
Attendance, attitude and work habits		10-20% of grade 
TOTAL						100%

Attitude and Work Habits: Although attendance is important, productive
attitudes and work habits affect morale, efficiency, accuracy and safety
in the automotive shop and will be a factor in determining grades.  In
addition, collaboration and teamwork will be expected and evaluated. 

Caveats:

  1. Safety glasses with side shields are required to be worn during lab activities for this course. This is in compliance with accepted eye protection practices and Kansas State Law (K.S.A. 72-5207). Safety glasses must meet American National Standards Institute Z87.1 specifications. (NOTE: Most prescription eyewear does not meet ANSI Z87.1. Students who wear prescription glasses must: a) Provide evidence that existing eyewear meets ANSI Z87.1, or b) Wear cover goggles (if allowable), or c) Purchase and wear ANSI Z87.1 prescription eyewear.
  2. Lab Guidelines: In order to assist with the safe and efficient operation of the automotive lab area, students are expected to be familiar with and adhere to the Automotive Student Lab Guidelines.

If you are a student with a disability, and if you will be requesting accommodations, it is your responsibility to contact Access Services. Access Services will recommend any appropriate accommodations to your professor and his/her director. The professor and director will identify for you which accommodations will be arranged.
