How Is Assessment Weighting Calculated?


In courses that contain more than one assessment, you may want to factor in multiple assessment scores towards your users' overall course score. You could use a simple averaging method based on equal balancing between each of the assessments. 

There are other scenarios where you may want to weight different assessments differently and this can be set up when you add or edit an Assessment, SCORM, Tin Can, or AICC learning object.

Back to the original question at hand though: how do these weights work? Simply put, these weights are a ratio relative to the other weights of your course's other assessments. You can enter whatever values you'd like here: for example two assessments with weights of 1 and 2 would be treated exactly the same if they had weights of 100 and 200, with one being worth twice as much as the other. 
Here's an easy way to calculate the score that will be passed to the course level based on the weighting you have set up: 
AssessmentScore x (AssessmentWeight/TotalWeight) 
Let's say you have 3 assessments in a course with weights 3, 7, and 14, respectively:  
Now let's say a user scores 88%, 97%, and 73% in each of these assessments, respectively: 
88% x (3/24) = 0.88 x 0.125 = 0.11 
97% x (7/24) = 0.97 x 0.292 = 0.28 
73% x (14/24) = 0.73 x 0.583 = 0.43 
0.11 + 0.28 + 0.43 = 0.82 
Course Score = 82% 
By using assessment weighting, course creators can achieve deep and versatile multi-assessment scoring setups in Absorb LMS' online courses.
