Can I adjust the consolidated value for each competency again at the end?
You have the option of setting a final value for the individual competencies per candidate in the single view of the candidates in the conference.
To do this, activate the option under "Settings" in the templates/assessment in the administration interface and then navigate in the observer interface to the single view of the candidates. In the column on the far right with the "flag" you can then set a final value. To do this, click on the "pencil" and move the slider to the desired value.
You can find more information about the final consolidation of competencies here.
