Higher Education Institutions or instructors may require students to take certain ALEKS assignments in Respondus LockDown Browser, which is a secure testing browser that restricts students from accessing other applications. LockDown Browser can be required for ALEKS tests, quizzes, scheduled Knowledge Checks, and PPL Placement Assessments. Respondus Monitor, a companion application for LockDown Browser, can also be required for assignments that require LockDown Browser. Respondus Monitor uses students' webcams to record a video as they complete the assignment, and flags suspicious activity for the institution or instructor to review. More information about the Respondus Monitor can be found here: https://mh.my.site.com/aleks/s/article/Respondus-Monitor?dc=
