                Evaluation will be in accordance with the Bellefonte Area High School grading policy as stated in the handbook.  In accordance with individual potential, a student is expected to master the level of achievement for his/her level.  The student’s efforts to reach the outcome will be measured by the teacher during classroom observations of the student and his/her work.  Final grades will be determined by averaging the actual grade from each quarter according to the following:

     A: 100-90%, B:  89-80%, C:  79-70%, D:  69-60%, and F:   59-0%

    Classroom Grade will be evaluated by the following:

                1.  Quizzes and Tests                          20%

                2.  Class Activities (class work)        60%

                3.  Projects                                          20%

    Grading Policy:

                Students are expected to work during time they are given.  Most of the materials and software used for this course must stay in the classroom.  Students will be able to come down and work during a study hall.  There will be little homework throughout the year.  They must be focused and concentrate on the task at hand.  Principles of Engineering is a fast passed course.  There is a lot of information to go over.  Students that are absent frequently will have a harder time doing well in the course.  You must make arrangements with the teacher to make up the missed information and assignments. Students will not fail if 100% effort is given in a project no matter what the outcome of the project may be.
