Login to Blackboard and open your course.

Click "View everyone in your course" under the Roster heading.

Click the three dots next to the name of the student who requires an accommodation. 

Type in the % of extra time the student is allotted according to their accommodation.

Applying the accommodations at the roster level applies the accommodation to all tests/assignments created within the course. This means you only have to apply the accommodation once!
