+
+PrairieTest now supports Respondus LockDown Browser. For any exam linked to a PrairieLearn assessment, instructors
+and testing centers can require students to take the exam inside a secure, locked-down environment,
+configured directly from PrairieTest alongside everything else.
+
+---
+
+## What is Respondus LockDown Browser?
+
+[Respondus LockDown Browser](https://web.respondus.com/he/lockdownbrowser/) is a secure web browser purpose-built for online exams. While a student is taking an exam, it prevents them from opening other applications, switching tabs, copying or printing content, accessing screen-sharing or virtual machines, and using most keyboard shortcuts, effectively turning the device into a secure testing environment for the duration of the assessment.
+
+## How the integration works in PrairieTest
+
+### What students see
+
+Instead of the regular "Start exam" button, students see "Open in LockDown Browser" on their reservation page:
+
+<BlogImage
+  src={takeExamLockdown}
+  alt="PrairieTest exam page showing 'Open in LockDown Browser' button and a Help link"
+  caption="Students see an 'Open in LockDown Browser' button when their exam requires it."
+/>
+
+Clicking it opens the reservation inside LockDown Browser, where they can start the exam in the protected environment. For installation steps and supported platforms, point students to the [LockDown Browser docs page](https://prairietest.com/pt/docs/lockdown-browser/).
+
+### Setting it up for your course
+
+LockDown Browser can be configured in two different ways, depending on the exam circumstances.
+The setting always lives closest to the student’s computer: the course session for instructor-run exams,
+and the testing center location for center-scheduled exams.
+
+#### Option 1: Course-run sessions (online or in-class)
+
+For course-specific exams that don't depend on a CBTF, the setting is per-session and lives on the course session itself, so course staff control it directly. Every reservation against that session will open the linked PrairieLearn assessment in LockDown Browser. See the [PrairieTest setup docs](https://prairietest.com/pt/docs/lockdown-browser/) for the toggle.
+
+<BlogCalloutBox title="Heads up" variant="note">
+  Tip: Because students need to install LockDown Browser on their own computers
+  beforehand, announce the requirement to your class ahead of exam day.
+</BlogCalloutBox>
+
+#### Option 2: Sessions scheduled into a PrairieTest testing center
+
+For exams scheduled into a testing center, the setting is not per-session and lives on the location,
+so every session that runs at that location inherits it automatically.
+This keeps a center’s policy consistent and ensures the machines
+(which require a special lab-mode installer) match what the session expects.
+
+This means:
+
+**If you’re course staff:** you don’t toggle anything yourself. Coordinate with the testing center to confirm whether LockDown Browser is enabled at the location your students are scheduled into. The session settings page shows the inherited value as read-only, with a link out to the center docs.
+
+<BlogImage
+  src={sessionSettingsInherited}
+  alt="PrairieTest session Settings tab showing LockDown Browser: Yes with the note ‘Inherited from this location.’ and a link to ‘LockDown Browser at testing centers’"
+  caption="On a session at a LockDown Browser location, course staff see the setting as inherited and read-only."
+/>
+
+**If you’re center staff:** enable LockDown Browser once on the location’s Settings tab and every center session there will use it automatically. The toggle is documented in the [PrairieTest setup docs](https://prairietest.com/pt/docs/lockdown-browser/).
+
+<BlogCalloutBox title="Heads up" variant="note">
+  Make sure the center's computers have the lockdown browser installed, and that
+  the proctors know how to help students with setup.
+</BlogCalloutBox>
+
+## Final thoughts
+
+Native LockDown Browser support brings one of the most-requested proctoring tools into the same workflow as
+the rest of your PrairieTest exams. No separate dashboards, no parallel configuration. Whether you run an
+online quiz, an in-class assessment, or a CBTF exam, you can require a locked-down environment in a couple
+of clicks. We’re excited to see how courses put it to use.
