The next weekend tests open to Irvine students are the SAT on November 7 and December 5, 2026, and the ACT on December 12. Both testing organizations turn students away for unacceptable ID or late arrival, and neither test allows calculators with a computer algebra system (CAS). Test-day preparation is more specific than many families expect: ID, devices, calculators, and arrival times each have fixed rules.
SAT and ACT Test Day Rules: What Has Been Published
College Board and ACT each publish complete weekend test-day rules on their websites; this article reflects those pages as of October 13, 2026. The SAT is now taken entirely on the Bluebook app, on a device the student brings. The ACT is offered on paper, online at the test center, and online on the student’s own laptop. Registration dates for the two tests are as follows:
| Test | Regular registration deadline | Late registration and changes | Notes |
|---|---|---|---|
| SAT, November 7 | October 23 | October 27 | Deadlines are 11:59 p.m. Eastern Time |
| SAT, December 5 | November 20 | November 24 | A College Board loaner device must be requested at least 30 days ahead, which works out to November 5 |
| ACT, December 12 | November 6 | November 29 (late fee applies) | Initial scores are released December 22 |
What SAT and ACT Test Day Rules Mean for Irvine Families
Irvine Unified School District (IUSD) offers the PSAT 8/9 free to 9th graders, the PreACT to 10th graders, and the PSAT/NMSQT to 11th graders. These are in-school tests that schools register and administer. Many students first learn when registering for a weekend test that the device, the ID, and the arrival time are now their own responsibility. Failing any one of these can mean being refused admission, and test fees are not refunded.
What to Bring on SAT Test Day
College Board lists six required items for the SAT and five optional ones:
- A fully charged testing device with Bluebook installed and exam setup completed.
- An admission ticket, generated in Bluebook after exam setup 1 to 5 days before the test; College Board prefers a printed copy.
- A physical photo ID; electronic IDs are not accepted.
- Pencils or pens for scratch work.
- The student’s College Board username and password.
- An acceptable calculator: Bluebook includes an embedded Desmos calculator that toggles between scientific and graphing modes, so a handheld calculator is optional.
- Optional items: a watch without an audible alarm, a charging cable or portable charger, a bag, a drink or snacks for the break, and a backup device.
Bluebook runs on a Windows laptop or tablet, a Mac laptop, an iPad, or a school-managed Chromebook. It does not run on a personal Chromebook, a mobile phone, or a Linux device. College Board advises downloading the app at least 30 days before test day so that there is time to find another device if the first one does not qualify.
SAT ID and Arrival Time Rules
SAT ID must be a valid government-issued ID or a student ID from the school the student currently attends, and the name must match the admission ticket exactly; a nickname on one and a full name on the other is not accepted. School IDs from the prior school year remain valid through December 31 of the current year, so 2025-26 school IDs can be used through December 31, 2026. Birth certificates, Social Security cards, temporary IDs, and digital IDs on a phone are not accepted, and students 21 or older may use only government-issued ID. Students who need to change their name must contact customer service at least 30 days before the test.
Test centers open at 7:45 a.m., doors close at 8:00 a.m., testing starts between 8:15 and 8:30 a.m., and standard-time testing ends around 10:45 to 11:00 a.m. Students borrowing a College Board device arrive at 7:15 a.m. Late students cannot be admitted and must register again and pay the standard fee. There is one 10-minute break, each module is timed separately, and students cannot return to a module once they have moved on.
What to Bring on ACT Test Day
ACT students must be inside the test center by 8:00 a.m., and late arrivals are not admitted. Required and permitted items are as follows:
- An admission ticket, printed from MyACT after the student’s photo is uploaded and approved; a student who forgets it can still test, but paper-test scores may be delayed.
- A photo ID that is an original hard plastic card issued by a city, state, or federal agency or by the student’s school; paper and electronic IDs are not accepted. A student without one must bring the ACT Student Identification Form completed by a school official or notary public, not a relative.
- Sharpened No. 2 pencils with erasers; pens and mechanical pencils are not allowed.
- A personal laptop (BYOD), only for students registered for online testing on their own device, fully charged and with a charger.
- A watch without an alarm, a permitted calculator, and snacks: the calculator is for the math test only, and snacks are eaten outside the testing room during breaks.
Highlighters, correction fluid, scratch paper, and electronic devices may not be brought into the testing room. ACT schedules a short break after the second test, and phones may not be used during breaks either. Ending times depend on the options chosen: the online ACT without add-ons ends at 11:05 a.m. and with science and writing at 1:00 p.m.; the paper test ends at 11:25 a.m. and 1:30 p.m. respectively.
How SAT and ACT Calculator Rules Differ
Both testing organizations prohibit calculators with a computer algebra system (CAS), but they define the ban differently:
| Item | SAT | ACT |
|---|---|---|
| CAS calculators | All prohibited; any model that factors or expands expressions or gives exact symbolic solutions counts | Prohibited, naming all TI-89 and TI-92 models, TI-Nspire CAS, HP Prime, Casio ClassPad, and others |
| TI-Nspire (non-CAS) | Allowed | Allowed |
| Stored programs and documents | Programs with algebra functionality and all stored documents must be removed | All documents and all programs with CAS functionality must be removed |
| Built-in calculator | Desmos embedded in Bluebook | Desmos built into the online test |
| Other rules | Must be placed under the desk during Reading and Writing; no power cords | Sound must be turned off; infrared ports must be fully covered with opaque tape |
Consequences of SAT and ACT Test Room Violations
Both testing organizations enforce device rules strictly. The SAT bars phones, smartwatches, wireless earbuds, external keyboards for laptops, and iPad styluses during testing and breaks; a student whose device makes noise or is seen may be dismissed immediately and have scores canceled. On the ACT, a student who accesses or activates a device is dismissed and the test is not scored. An ACT registration cannot be canceled once submitted, and a paper-test student who breaks the seal on the test booklet can no longer request a test date change.
EDUBUS Recommendations for SAT and ACT Test Day
EDUBUS recommends checking the name on the ID a week before the test. The SAT requires the ID name to match the admission ticket exactly, with name changes due 30 days ahead, and the ACT accepts only an original hard plastic ID. ID problems are hard to fix close to the test, so checking early matters.
EDUBUS recommends checking the calculator model now. A student who does homework on a TI-89 or TI-Nspire CAS cannot bring it into either test. The student can switch to a non-CAS model or practice in advance with the built-in Desmos calculator.
EDUBUS recommends allowing 30 days to prepare an SAT device. Borrowing a device from school or family takes time if the student’s own device does not qualify, and a College Board loaner must be requested 30 days ahead. Students taking the December 5 SAT should settle on a device by November 5.
