Once you have activated the Assessment by skills in your group, you can start assigning each skill to the columns. To do so, create a column with a title and a type of mark or rubric. If you have selected the Assessment by skills option in the group, a row will appear under the title of the column. Click on that row and choose the skills that will assess this activity or test you are working on.
Once it has been selected, you will have the option of the skill you want to use, with a space at the right side of the skill to enter the weighing. This will affect the value it will have when setting the final mark. The marks of the students assessed with skills will be determined by the weighing of each skill. The higher the weighing you assign to a skill, the higher the importance it will hold for the final mark of the activity. You can also assign the skills linked to the standards. In this case, the weighing will have to be modified in the set up of the standard.
