Department Guidelines

There are 12 individual projects and 1 group project. All assignments are graded for construction neatness, preciseness, and completion. Individual assignments are due at the end of the scheduled week. make up and late work are not counted towards your grade.

Group assignments are divided into 2 or 3 groups and the one student leads the group to complete the project. Each group keeps construction records, man hours, bill of materials, blue prints, and cost of materials. These records must be turned in with the completion of the projects.

Grades will be based on the number of accumulated points earned on tests, quizzes, and homework.
