Students typically complete a variety of assignments during a grading period such as homework, quizzes, performance assessments, etc. Teachers have to decide preferably before the grading period begins how each assignment will be weighted. For example, a sixth grade math teacher may decide to weight the grades in the following manner:

Weekly quizzes 35 per cent
Homework 15 per cent
Performance Assessment 30 per cent
Class participation 20 per cent

Deciding how to weight assignments should be done carefully as it communicates to students and parents what teachers believe is important, and also may be used to decide how much effort students will exert (e.g. “If homework is only worth 5 per cent, it is not worth completing twice a week”).

Should social skills or effort be included? Elementary school teachers are more likely than middle or high school teachers to include some social skills into report cards (Popham, 2005). These may be included as separate criteria in the report card or weighted into the grade for that subject. For example, the grade for mathematics may include an assessment of group cooperation or self regulation during mathematics lessons. Some schools and teachers endorse including social skills arguing that developing such skills is important for young students and that students need to learn to work with others and manage their own behaviors in order to be successful. Others believe that grades in subject areas should be based on the cognitive performances and that if assessments of social skills are made they should be clearly separated from the subject grade on the report card. Obviously, clear criteria such as those contained in analytical scoring rubrics should be used if social skills are graded.

Teachers often find it difficult to decide whether effort and improvement should be included as a component of grades. One approach is for teachers to ask students to submit drafts of an assignment and make improvements based on the feedback they received. The grade for the assignment may include some combination of the score for the drafts, the final version, and the amount of improvement the students made based on the feedback provided. A more controversial approach is basing grades on effort when students try really hard day after day but still cannot complete their assignments well. These students could have identified special needs or be recent immigrants that have limited English skills. Some school districts have guidelines for handling such cases. One disadvantage of using improvement as a component of grades is that the most competent students in class may do very well initially and have little room for improvement unless teachers are skilled at providing additional assignments that will help challenge these students.

Teachers often use “hodgepodge grading”, i.e. a combination of achievement, effort, growth, attitude or class conduct, homework, and class participation. A survey of over 8,500 middle and high school students in the US state of Virginia supported the hodgepodge practices commonly used by their teachers (Cross & Frary, 1999).
