A shared reference for the whole exam room
An exam room clock gives candidates and invigilators a clear view of the current time. Alongside it, the display can show when the exam starts, when it finishes and how much time remains. Everyone sees the same information without needing to ask for a time check.
Exam Room Clock is built for formal examination spaces: a school classroom, a university lecture theatre or a large exam hall. It runs in a browser on the computer connected to your screen. There is no account to create and no software to install before you can open the display.
Ready in a few simple steps
- Check that the computer’s date, time and timezone are correct.
- Enter the exam date, start and finish times. Add a title or room if useful.
- Choose the information candidates should see, then select Launch Exam Display.
- Move the display to your projector or classroom screen. Check it from the back of the room before candidates arrive.
The exam room clock setup guide includes an offline check and the settings to review before an exam.
Current time, not just a countdown
A countdown tells you how long is left. A current-time clock also lets invigilators compare the display with the published schedule and communicate a clear finish time. That distinction matters when one exam follows another or when candidates enter a room at different points in the day.
The current time is the largest item on this display. Remaining time is optional, as are the title, start and finish times. Choose the information appropriate to the exam rather than assuming every field must be shown. Read more about the exam clock and its display options.
Visible on projectors and classroom screens
Large numerals, a quiet layout and a choice of light or dark appearance keep the focus on time. Four clock sizes help you adapt the display to the screen, but no font setting can compensate for a screen that candidates cannot see. Check sightlines, room lighting and any cropped projector edges in the actual room.
Use the exam display guide to choose a layout, or follow the projector setup instructions for a second screen.
Built to recover when the browser pauses
The clock recalculates from the computer’s current time and the exam’s saved start and finish timestamps. It does not keep time by repeatedly subtracting a second. If a background tab slows down or a computer wakes from sleep, the next update shows the time for that moment.
This does not independently verify your device clock or keep a sleeping screen visible. Check automatic date and time settings beforehand, connect the computer to power and review its sleep settings. Where supported, the display offers a screen wake lock.
Prepare online. Keep running offline.
After the site has prepared its local cache, the configuration screen shows “Ready offline”. The core clock then works without an internet connection on that browser and device, including reloading the display. It does not call an API to run an exam.
Test offline loading before relying on it. Private browsing, cleared site data or browser storage eviction can remove the cache. Installation is optional; it provides a standalone window on browsers that support it.
For the people running the examination
Schools can prepare a familiar classroom display between exam sessions. Universities can use it on lecture theatre and hall screens, checking each device separately. Exam officers and invigilators can save time on routine setup while keeping the date, room and finish time visible during checks.
The free version handles one exam schedule on each display. It does not remotely synchronise rooms or manage extra-time groups. Exam Room Clock is an independent tool; check your current examination regulations and institutional procedures before deciding what to display.
