What is BYOD assessment – and how can it work at scale?

From computer rooms to exam halls

Many universities want to move exams from paper to screen, but few have enough computer rooms to examine large cohorts at once. Building and maintaining them is expensive, and they stand idle much of the year. BYOD assessment offers a different route: instead of bringing students to the computers, the exam comes to the devices students already own and use every day.

Today, BYOD exams are run at scale across Europe, often for thousands of students at a time – usually combined with a lockdown browser and human invigilation, so that a personal laptop becomes a controlled exam device.

How does it work?

Practices vary, but BYOD assessment usually involves the following:

• Minimum requirements. The institution sets out which devices and operating systems are supported, and students check their device in advance.
• Software and practice. Students install any required software, such as a lockdown browser, and try a practice exam before the real one.
• A secure exam environment. During the exam, the lockdown browser restricts the device to the exam, while invigilators supervise the room.
• Infrastructure in the venue. Stable Wi-Fi and enough power sockets are provided for every student.
• A safety net. Loan laptops and on-site technical support are ready for students whose device fails or who do not have a suitable one.

Why does BYOD assessment matter?

The main reason is scale at a sustainable cost. BYOD lets institutions run digital exams for large cohorts without investing in and maintaining large computer rooms, and makes it possible to use a wider range of venues.

It also benefits students. Writing on a familiar machine creates security: students know the keyboard, the trackpad and their own shortcuts, instead of adjusting to an unfamiliar computer under exam pressure. For many students with disabilities, it also improves accessibility – their own device is already set up with the settings, screen and assistive technology they use every day. And typing is faster and easier to edit than handwriting, with answers that are always legible. For staff, there is no printing, transport or scanning of papers, and marking can start as soon as the exam ends.

What BYOD assessment cannot do

BYOD shifts some of the responsibility to students’ devices – and devices vary. Old operating systems, flat batteries, work laptops with restricted rights and unsupported devices can all cause problems if they are not caught in advance. Not every student owns a suitable laptop, and assistive software must work alongside the lockdown browser, so institutions must test and provide alternatives to keep the exam fair.

The venue matters too. Wi-Fi must cope with hundreds of devices at once, power must reach every desk, and screens may be visible to neighbours in a crowded room. And some subjects – such as those heavy on formulas or drawings – still need careful thought about how answers are best given on a screen.

How does WISEflow approach it?

WISEflow was built for BYOD from the start. Our understanding goes a little further than letting students bring a laptop:

• A wide range of devices. The WISEflow lockdown browser runs on Windows, macOS, iPad and Chromebook, with minimum requirements kept up to date in the WISEflow service centre.
• Secure, without a separate product. The lockdown browser is part of the platform, so a locked, invigilated exam runs in the same system as planning, marking and results.
• Built for real-world networks. If the connection drops on a computer, students can save an encrypted offline backup and upload it later.
• Tools inside the locked environment. Approved websites and built-in tools – such as a camera for appendix material, code and LaTeX editors and a drawing tool – can be enabled where the exam calls for them.

What should institutions consider?

• Device policy: set clear minimum requirements, communicate them early and plan for students without a suitable device.
• Venues: test Wi-Fi under load, and make sure there is power for every student.
• Support: have loan laptops and technical staff ready on exam day.
• Preparation: give students a practice exam, so the technology is familiar before it matters.

BYOD assessment is not just a cheaper alternative to computer rooms. Planned well, as part of a considered approach to digital assessment, it makes secure digital exams possible at any scale – on the devices students already know.
