Courses Measures and Assessments
Student progress throughout this course will be measured with his or her relative success with the completion of circuit creation, identifying hardware and its duty, scenarios of electric troubleshooting, and measurement techniques. Successful completion of the projects will require utilization of the skills covered in ELW110, Practical Problems in Mathematics for Electricians.
Specific guide sheets developed for each individual project will be used to assess each student’s performance in the courses.

Grades earned in courses impact academic progression and financial aid status. Before withdrawing from a course, be sure to talk with your instructor and financial aid counselor about the implications of that course of action. Ds, Fs, Ws, WFs and Is also negatively impact academic progression and financial aid status.
The Add/Drop Period is the first 5 days of the semester for full term classes. Add/Drop periods are shorter for accelerated format courses. The following week of the semester is Financial Aid Attendance Verification period. You must attend at least one meeting of all of your classes during that period. If you do not, you will be dropped from the course(s) and your Financial Aid will be reduced accordingly.
