SAT Device Rules 2026: Backup Devices, Wi-Fi and Bluebook

Digital SAT Device Rules for Fall 2026: Backup Devices, Wi-Fi Failures, and What Bluebook Requires

This guide is part of the complete Digital SAT Prep Guide.

The test is in three weeks. The laptop is four years old, the school Chromebook may or may not be allowed, and someone on a forum said their Wi-Fi dropped mid-module and they were sure they had lost the test. None of this is about the SAT itself, and all of it is capable of costing a test date.

The rules are specific, they changed for the fall 2026 cycle, and nearly all of the failure modes have a documented answer. Here is what College Board actually requires, in the order you will need it.

Which devices work in fall 2026

Bluebook runs on four kinds of device and nothing else.

Personal Chromebooks and phones cannot run Bluebook. Android tablets are not on the supported list. A laptop needs a screen of at least 10 inches, a tablet at least 8, and every device must hold a charge for at least three hours — College Board's consumer guidance says three to four — because outlets in the testing room are not guaranteed.

The Windows 10 change is the one catching families this fall. Microsoft ended support for Windows 10, and College Board followed. A student who tested on Windows 10 in the spring will need to update or use a different device for November or December.

The setup timeline that cannot be done on the morning

Bluebook has to be installed and the exam has to be set up in advance, and the steps have deadlines.

The 1–5 day window is the one to put in a calendar. Exam setup not done means no admission ticket, and no admission ticket means no test.

If Bluebook will not open on a personal device, College Board's first troubleshooting step is to disable any VPN or content filter, which commonly blocks the connection.

Backup devices: what they can and cannot do

College Board lists a backup testing device as an optional item to bring, and it is the single most useful thing on that list. The rules:

• You test on one device at a time. The backup sits in the bag until needed.
• If your device fails during the test and cannot continue, you can switch.* The proctor or the center's tech coordinator helps with the switch.
• The backup must be ready.* Same requirements, Bluebook installed, exam setup completed. A backup that needs an OS update at 8 a.m. is not a backup.
• A backup is exempt from the prohibited-electronics rule*, which otherwise bans phones, smartwatches, wireless earbuds and similar items from the room.

College Board does not publish whether switching devices costs testing time. The Wi-Fi-outage guidance says no time is lost, but a hardware swap is a different event, and the honest answer is that a student who has to switch should assume some disruption and move on. Having the second device ready is what limits it.

A student who arrives without any working device is dismissed unless they were pre-approved to borrow one, and rescheduling is a customer-service conversation rather than an automatic right. That is the failure mode the backup exists to prevent.

What happens when something fails mid-test

The "phone in the bag" row is not an exaggeration. If a prohibited device makes noise, is seen, or is accessed at any point including breaks, the student can be dismissed, the score canceled, and the device confiscated for inspection. Smartwatches, fitness trackers, smart glasses and wireless earbuds are in the same category. A simple analog or non-smart watch is fine.

Calculator rules

The built-in Desmos calculator is available throughout the Math section, can be toggled between graphing and scientific modes, and for the fall 2026 cycle can be resized on screen. Bringing a handheld is optional. If you do:

• Non-CAS only — no computer algebra system, meaning nothing that solves or factors equations symbolically. Prohibited: TI-Nspire CAS and TI-Nspire CX II CAS, any model beginning TI-89 or TI-92, anything with "CAS" in the name, HP Prime and the HP 40G/48GII/49G/50G series, and the Casio ClassPad and Algebra FX models. TI-Nspire models without CAS in the name are allowed, as is the entire TI-84 family.
• Remove algebra programs.* Any program that solves, expands or factors equations must be deleted before testing, along with stored documents.
• Battery-powered and handheld only.* No power cords, no QWERTY keyboards, no wireless connectivity, no cameras.
• Reading and Writing section: calculator under the desk.* It may not be out.

Whether to use a handheld at all is a strategy question rather than a rules question. For Algebra systems and for locating intersections of nonlinear functions in Advanced Math, Desmos is faster than any handheld. For a student who has practiced exclusively on a TI-84, switching on test day is a mistake.

Borrowing a device from College Board

Students who do not have access to a qualifying device and cannot borrow one from school, family or a friend can request one from College Board during registration. The rules are strict enough to list:

• Request at least 30 days before test day; the device ships directly to the test center.
• A non-family adult — teacher, counselor, school administrator or college-access program staff — must verify eligibility.
• Approval is not guaranteed and is subject to availability.
• Arrive 30 minutes before standard check-in to receive the device and complete exam setup on it.
• Changing test centers inside 30 days may mean the device cannot follow you.

If a loaner is the plan for December 5, the request needs to be in by early November, and the registration itself closes November 20.

Other fall 2026 changes worth knowing

Beyond the Windows 11 and Chromebook Verified Mode requirements, two things are new this cycle. Students approved for the embedded text-to-speech accommodation can now test at any test center rather than only at school, and must bring their own wired, non-Bluetooth headphones — see our SAT accommodations guide. And a waitlist feature has launched in the United States for test dates and centers that are already full, which matters for anyone who finds their nearest center booked for November or December.

The checklist

Print this, or screenshot it, for the week of the test.

• Device on a supported OS (Windows 11 24H2 / macOS 15 / iPadOS 18 / school-managed ChromeOS 144)
• Bluebook installed and opened successfully at least once
• Exam setup completed 1–5 days before; admission ticket printed
• Backup device prepared identically, if you have one
• Charger packed; device fully charged the night before
• Handheld calculator, if bringing one: non-CAS, programs cleared, fresh batteries
• Photo ID
• Phone and watch powered off before entering the room
• Bluebook reopened on the morning of the test

Take the diagnostic

Device readiness is a checklist; it is either done or not. The thing that is not a checklist is whether the student walking in with the fully charged laptop knows which of the eight Digital SAT domains is going to cost them points, because that is what the remaining weeks should have gone to.

The MySatCoach diagnostic reports accuracy at the skill level inside Craft and Structure, Information and Ideas, Standard English Conventions, Expression of Ideas, Algebra, Advanced Math, Problem Solving and Data Analysis and Geometry and Trigonometry, in about 15 minutes. Run it once the device is sorted.

Frequently Asked Questions

Can I bring a backup laptop to the SAT?

Yes, and College Board lists a backup testing device as an optional item to bring. You can test on only one device at a time, but if yours fails during the test and cannot continue, the proctor or tech coordinator can help you switch to your second device. The backup has to meet the same requirements and have Bluebook installed with exam setup completed, so prepare it exactly as you prepared the main one.

What happens if the Wi-Fi drops during the Digital SAT?

Nothing, as far as your score is concerned. Bluebook is built to run through an outage: you keep working, your answers are saved on the device, and no testing time is lost. The only step that needs a connection is the final submission. If you are still offline at the end, you have until 11:59 p.m. local time the next day to reconnect and submit by signing in to Bluebook from your My SAT page.

What devices can I use for the Digital SAT in 2026?

A Windows laptop or tablet on Windows 11 (version 24H2 or later), a Mac on macOS 15 or later, an iPad on iPadOS 18 or later, or a school-managed Chromebook on ChromeOS 144 or later with Verified Mode enabled by the school. Personal Chromebooks and phones cannot run Bluebook. Windows 10 is no longer supported for the fall 2026 test cycle. The device must hold a charge for at least three hours, and outlets are not guaranteed.

Can I use my own calculator on the Digital SAT?

The built-in Desmos calculator is available for the whole Math section, and you may also bring a handheld non-CAS calculator. TI-84 models are fine; TI-Nspire CAS, TI-89 and TI-92 models, HP Prime and Casio ClassPad are prohibited. Any program with algebra functionality must be removed before testing. If your handheld dies, Desmos is still there.
