Student grades will reflect the completion of all work, including outside assignments. Homework is also part of the student's preparation for State mandated tests. Selected learning experiences and skill development activities may be expanded and/or reinforced by extending class work through the assignment of school work to be done outside of the regular class schedule. Teachers may give homework to students to aid in skill development and the attainment of appropriate achievement levels. The type, frequency, and quantity of homework should be based on the needs and capacities of students as determined by the professional judgment of the teacher, and homework should be an application or adaptation of classroom instruction. Parental cooperation and assistance are essential to meet the instructional expectations and objectives of the student.
