# Composite vs. Cumulative

## Overview

Overall, you can set up your **GradeBook** one of two ways: **Cumulative **or **Composite**. This article explains the differences. Dependent upon Administrative selections, some options shown below may not be available as some schools, boards or districts mandate that all staff use one or the other.

### Calculation Types

There are a total of eight calculation types. The most commonly used are Composite or Cumulative. The other six selections are extrapolations of the two commonly used choices.

**Composite:** an average score calculated using the Task scores a student earns within a **single **Report Period.

**Composite (Ignore Category Weights):** calculated using the Task scores that occur within* *a single Report Period. Unit and Task weights are considered. Category Weighting is ignored.

**Composite (Ignore Unit Weights):** calculated using the Task scores that occur within* *a single Report Period. Category and Task weights are considered. Unit Weighting is ignored.

**Composite (Ignore Unit and Category Weights): **is calculated using the Task scores that occur within a single Report Period. Unit and Category weights are ignored Task weights are considered.

**Cumulative: **is an accumulation of successive scores calculated using the Task scores that occur from the beginning of the year up to, and including, the selected Report Period.

**Cumulative (Ignore Category Weights): ** is calculated using the Task grades that occur from the beginning of the year up to, and including, the selected Report Period. Unit and Task weights are considered. Category weights are ignored.

**Cumulative (Ignore Unit Weights):** is calculated using the Task scores that occur from the beginning of the year up to, and including, the selected Report Period. Unit Weighting is ignored. Category and Task weights are considered.

**Cumulative (Ignore Unit and Category Weights): **is calculated using the Task scores that occur from the beginning of the year up to, and including, the selected Report Period. Unit and Category weights are ignored. Task weights are considered.

### Composite Calculation

Composite score is an average grade calculated using the Task scores a student earns within a single **Report Period**. Unit, Category and Task weights can all be considered or ignored as per calculation type selected but will only one Report Period at a time will be considered.

The **Final Mark** is an average of the individual Report Period grades. Essentially, it is "an average of all of the averages" since each Report Period is an average of the grades your students earned *in *that Period. Report Periods can be weighted **if **Administrative permissions allow.

Example based on equal weighting of Report Periods

**Step 1: ** Add each Report Period Grade (75+62+80+70=287)

**Step 2:** Divide the sum by the number of Report Periods (287/4=71.75)

Report Period 1 |
Report Period 2 |
Report Period 3 |
Report Period 4 |
Final |

75 | 62 | 80 | 70 | 72 |

75 + | 62+ | 80+ | 70= | 287/4=71.75 |

### Cumulative Calculation

Cumulative grade is an accumulation of successive scores calculated using the Task Grades that occur from the beginning of the year up to, and including, the selected **Report Period**. Unit, Category and Task weights can all considered or ignored as per the calculation type selected, however, all of the Report Periods are taken together as if they were, essentially, one Report Period.

The **accumulated grade** continues throughout the school year. If there is a Final Mark, it is an average of all grades earned during that year.
