At the core of the LifterLMS grading systems are quizzes and (with the LifterLMS Assignments Add-on) assignments. Quizzes and assignments are attached to lessons and are used to require additional steps to be taken before progressing a course forward, to test the student’s comprehension of lesson content, and much more.

The grades of a student’s quizzes and assignments serve as the base numbers used in all grading calculations.

By default, LifterLMS weights all quizzes and assignments equally but by leveraging weighting options available for lessons, quizzes, and assignments it’s easy to place greater emphasis on selected lessons, quizzes, or assignments.

LifterLMS utilizes **Weights** and **Points Values** to calculate percentage values. These values are positive whole numbers (and zero to denote an excluded item). In the course builder you will be required to enter these numbers and the equivalent percentage value is automatically calculated and displayed for you.

Percentages are difficult to work with in this context because whenever the percentage value of one item is adjusted, all other items must also be simultaneously updated so that the total percentage value of all items *always equals 100%. *By using a weight instead of a percentage the total weights do not need to add up to 100.

For example the total available points in a quiz might be 8 (eight). Assuming there’s eight questions, each worth one point, each question would be worth 12.5% of the total grade of the quiz.

Should you choose to change the value of the last question of the quiz you can simply increase the number of points that question is worth until it reaches your desired percentage and you *do not need to make any adjustments to any of the other 7 questions!*

The **Weight **of a lesson represents the lesson’s percentage value within its course.

By default, all lessons are valued equally, each having a default **Weight **of 1 (one). A lesson with a higher **Weight **has greater impact on the overall grade of a course than a lesson with a lower **Weight**.

A common example would be a “Final Exam” which counts as a higher percentage of the overall course grade than the other “regular” quizzes.

To create a course with this structure you could configure the lesson **Weight** values as follows;

Lesson 1 - Weight 1 (12.5%) Lesson 2 - Weight 1 (12.5%) Lesson 3 - Weight 1 (12.5%) Lesson 4 - Weight 1 (12.5%) Lesson 5 - Weight 4 (50%)

If the lesson *contains no quiz or assignment *it automatically has a **Weight **of 0 (zero) and is excluded for grading calculations automatically.

The **Weight **of a lesson is set within the lesson settings in the Course Builder.

When a lesson has both an assignment and a quiz, additional weighting options are made available to configure how each item impacts the calculated grade of the lesson.

By default, the **Quiz Weight **and **Assignment Weight **values are set to 1 (one). This means that the quiz and assignment each make up 50% of the lesson’s overall grade.

The **Quiz Weight **option is located on in the Quiz Settings area of the Course Builder:

The **Assignment Weight **option is located on in the Assignment Settings area of the Course Builder:

Just as the **Lesson Weight **allows weighting of lessons within a course, **Quiz Question Weights** make it possible to change the values of questions within a quiz.

Any weighted item in LifterLMS can be completely excluded from the resulting grade by setting it’s Weight to 0 (zero).

This will work for **Lesson Weight**, **Quiz Weight**, **Assignment Weight**, or **Question Points**.

When calculating the overall grade of a course, LifterLMS takes the following steps:

- Calculate the
**Total Available Points**for the course

Add together all the individual**Weight**values for each lesson in the course - Calculate a
**Weight-Adjusted Grade**for each lesson in the course

Multiply the**Lesson Grade**by the**Lesson Weight**for the lesson - Calculate the
**Weight-Adjusted Total**Add together all of the

**Weight-Adjusted Grades**for all lessons in the course

- Calculate the
**Overall****Course Grade**

Divide the**Weight-Adjusted Total**by the**Total Available Points**

##### Example

Lesson Weight Percentage Grade Lesson A 1 12.5% 80% Lesson B 1 12.5% 75% Lesson C 1 12.5% 50% Lesson D 1 12.5% 90% Lesson E 4 50% 85%

**1. Total Available Points**: 1 + 1 + 1 + 1 + 4 = **8**

**2. Weight-Adjusted Grades: **

Lesson Weight Percentage Grade Weight-Adjusted Grade Lesson A 1 12.5% 80% 80 = 1 x 80 Lesson B 1 12.5% 75% 75 = 1 x 75 Lesson C 1 12.5% 50% 50 = 1 x 50 Lesson D 1 12.5% 90% 90 = 1 x 90 Lesson E 4 50% 85% 340 = 4 * 85

**3. Weight-Adjusted Total**: 80 + 75 + 50 + 90 + 340 = **635
4. Overall Course Grade**: 635 / 8 =

**79.375%**

There are four different scenarios for a lesson when determining its grade:

**A. Lesson without a quiz or an assignment**

In this scenario the lesson’s **Weight** is **always** 0 (zero) and it is excluded from the course grading calculations.

**B. Lesson with a quiz only**

In this scenario the lesson’s grade is equal to the quiz grade.

**C. Lesson with an assignment only**

In this scenario the lesson’s grade is equal to the assignment grade.

**D. Lesson with a quiz and an assignment**

In this scenario the grades of both the quiz and assignment are used to calculate the lesson grade.

- Calculate the
**Total Available Points**for the lesson

Add the**Quiz Weight**to the**Assignment Weight** - Calculate the
**Weight-Adjusted Quiz Grade**

Multiply the**Quiz Grade**by the**Quiz Weight** - Calculate the
**Weight-Adjusted Assignment Grade**

Multiply the**Assignment Grade**by the**Assignment Weight** - Calculate the
**Weight-Adjusted Total**Add the

**Weight-Adjusted Quiz Grade**to the**Weight-Adjusted Assignment Grade** - Calculate the
**Lesson Grade**

Divide**Weight-Adjusted Total**by the**Total Available Points**

##### Example

Part Weight Percentage Grade Quiz 6 60% 70% Assignment 4 40% 100%

**1. Total Available Points**: 4 + 6 = **10
2. Weight-Adjusted Quiz Grade**: 70 x 6 = 420

**3. Weight-Adjusted Assignment Grade**: 40 x 4 = 160

**4. Weight-Adjusted Total**: 420 + 160 = 580

**5. Lesson Grade**: 580 / 10 =

**58%**

A quiz’s grade is calculated similarly to the grade of a course except that questions do not receive their own individual percentage grades and are instead awarded a number of points. To calculate a lesson grade:

- Calculate the
**Total Available Points**for the quiz

Add together the individual**Points**value of each question in the quiz - Calculate the
**Weight-Adjusted Points Value**for each point in the quiz

Divide the**Total Available Points**by 100 - Calculate the
**Earned Points**for the quiz attempt

Add together the total of all points for each correctly answered quiz question.

For manually-graded questions, any partial points awarded for an answer are added to this total. - Calculate the
**Quiz Grade**

Multiply the**Earned Points**by the**Weight-Adjusted Points Value**

##### Example

Question Points Percentage Earned Question A 3 20% 3 Question B 3 20% 3 Question C 3 20% 0 Question D 6 40% 4

**1. Total Available Points**: 3 + 3 + 3 + 6 = **15**

**2. Weight-Adjusted Points Value**: 100 / 15 = **6.667
3. Earned Points: **3 + 3 + 0 + 4 =

**10**

4. Quiz Grade:10 x 6.667 =

4. Quiz Grade:

**66.67%**

There are two different scenarios for assignment grades:

- Task assignments are pass/fail. If the assignment is incomplete it’s grade is 0%. Once the assignment has been completed it is automatically graded as “passed” with a grade of 100%
- All other assignment types are
*not calculated.*These assignment grades are entered by the instructor when they review the assignment. Therefore, the grade of the assignment is equal to the percentage value awarded by the instructor.
