The AMC 8 Rules Audit: What You May Bring, Who May Proctor, and the Post-Exam Rule Students Break in the Group Chat

Most AMC 8 advice is about mathematics. This page is about the other category of lost points — the rules that can invalidate a sitting no matter how well a student solves. Four of them catch China-based families repeatedly: a prohibited item in a pocket, a parent registering the competition, a second sitting at a second centre, and a photograph of the paper posted to a group chat that evening.

Why a twenty-minute rules audit is worth doing

A student who misreads a geometry item loses one point. A student who walks into the room wearing a smartwatch, or whose family registered them in a way the MAA does not permit, is in a different category of problem entirely — one where the mathematics never gets counted. These outcomes are rare, but they are also completely preventable, and unlike a weak topic they cannot be fixed afterwards.

The rules below come from the MAA’s published competition policies and the 2026 AMC 8 Teacher’s Manual. Read them once in August, run the checklist at the end of this page in the week before your sitting, and the whole category is closed. Everything here should be re-confirmed on maa.org and with your centre before the exam, because rules are revised between cycles.

The bag audit: what the MAA permits and prohibits

The permitted list is short, and it is a list of permissions rather than suggestions — anything not on it is, by default, not coming into the room with you.

Item Status What most people get wrong
Pencils and pens Permitted Bring spares; a broken pencil inside a 40-minute exam is expensive
Blank scratch paper Permitted, but provided by a teacher Do not bring your own paper from home — the site supplies it
Ruler Permitted Useful for drawing straight lines, useless for measuring an answer
Eraser Permitted Bring one that does not smear on an answer sheet
Calculator Prohibited The policy wording covers phones and similar electronic devices of any kind
Smartwatch Prohibited The single most common accidental breach — it is worn, not packed
Phone Prohibited Leave it with a parent or in a bag outside the room, not in a pocket
Compass Prohibited Often in a maths pencil case by default; empty the case the night before
Protractor Prohibited No angle on the paper is meant to be measured — all of them are derived
Graph paper Prohibited Coordinate questions are solved on blank paper; draw your own axes

Two of those entries are worth pausing on, because they carry a message about method rather than logistics. The absence of a compass and a protractor means no diagram can be constructed or measured; the absence of graph paper means no coordinate figure can be plotted onto a ready-made grid. Together they tell you that the exam expects every geometric quantity to be reasoned out. If a student’s habitual check on a geometry answer is to look at the picture and judge whether it seems right, that habit has no support in the room.

Two-column bag audit for the AMC 8. The permitted column lists writing utensils, blank scratch paper provided by a teacher, rulers and erasers. The prohibited column lists calculators, smartwatches, phones, computing devices, compasses, protractors and graph paper.
Anything not in the left-hand column stays outside the room. Emptying a maths pencil case is the step families skip, because compasses and protractors live in it by default.

The people rules: who registers, and who may sit at the front

This is the section that surprises China-based families most, because it constrains something they assume is theirs to arrange.

  • Students and parents do not register with the MAA directly. Registration is done by a competition manager at a school or an authorised site. If you have been told to create your own MAA account and register your own child, something has gone wrong — go back to the centre.
  • A parent or guardian may not register the competition. The MAA’s wording is unambiguous: under no circumstances may a parent or guardian of an AMC student register for the competition. This is a rule about who holds the competition manager role, and it exists to keep the person with access to the papers at arm’s length from the candidates.
  • The MAA requires the competition manager to be an adult not related to any participant and affiliated with the host organisation; confirm your centre’s proctoring arrangements with the centre and on maa.org. Both halves matter. A family friend who is not connected to the site does not qualify, and neither does a relative who teaches there.

The practical consequence is that your choice of centre is not an administrative detail you can settle in December — it determines whether the sitting is valid at all. A centre that is vague about who its competition manager is, or that offers to let a parent handle registration, is telling you something. Our guide to the in-person January AMC 8 and how China-based families find an authorised test centre sets out what to ask before you commit.

Competition Week: once, and only once

The MAA publishes the AMC 8 as a week rather than a fixed date. For this cycle that week is 21 to 27 January 2027, and the individual day inside it is chosen by whoever administers your paper. The rule that goes with the week is short and absolute: students can only take the AMC 8 once during Competition Week.

Say plainly what that forbids, because the temptation is real and occasionally marketed. Registering at two centres so a student can sit early, see the paper, and sit again later is not a strategy with a downside risk — it is a rules breach, and it exposes the student and both centres. A week-long window exists so that sites across many time zones can each administer once; it is not a set of retries.

It also means one calendar fact is not yours to control. Two students in the same city can sit six days apart, and you will not know your day until your centre tells you. Ask for it in writing, early, and build the last three weeks of preparation around the answer rather than around the middle of the window.

The embargo: the rule that gets broken in the group chat

Here is the one almost nobody in China has read. The MAA’s published rule states that problems and solutions are not discussed in any online or public forum until the day after the competition period ends at 8 a.m. ET.

Consider what that prohibits in practice. On the evening of the sitting a student photographs a question and posts it to a class WeChat group, or a parent asks in a group chat how everyone found question 23, or a student writes a solution thread. Each of those is a discussion in an online forum, and each happens while other students — possibly on the other side of the world, possibly at the school down the road with a later administration date — have not yet sat the same paper. That is exactly the harm the rule exists to prevent, which is why the embargo runs to the end of the whole competition period rather than to the end of your own day.

The time-zone arithmetic is worth doing once. Eastern Time in late January is UTC−5, and Beijing is UTC+8, a thirteen-hour gap with no daylight-saving complication at that point in the year. So 8 a.m. ET falls at roughly 9 p.m. the same calendar day in Beijing. That conversion is ours, not the MAA’s; treat it as a planning estimate, read the MAA’s own wording on maa.org, and if you are close to the boundary simply wait an extra day. Nothing is gained by posting early.

Timeline showing the discussion embargo. The competition period runs from 21 to 27 January 2027. Discussion of problems and solutions in any online or public forum is not permitted until 8 a.m. Eastern Time on the day after the competition period ends, which by our conversion is about 9 p.m. Beijing time the same day.
The embargo runs to the end of the whole competition period, not to the end of your sitting — because other students have not yet taken the same paper.

The pre-exam compliance checklist

Run items 1 to 4 as soon as a centre is confirmed, items 5 to 8 the night before, and item 9 on the evening after. None of it takes longer than twenty minutes in total.

# Check When Done when
1 Confirm the centre has a named competition manager who is not a parent of a candidate On booking You have a name and a role
2 Confirm the administration date inside 21–27 January 2027 On booking A single date, in writing
3 Confirm the student is registered at this centre only On booking One registration for the cycle
4 Confirm start time, arrival time and address On booking Written, with a travel plan
5 Empty the pencil case: remove compass, protractor, any graph paper Night before Only pens, pencils, ruler, eraser remain
6 Remove the smartwatch and set it aside with the phone Night before Neither is worn on the day
7 Leave your own scratch paper at home — the site provides it Night before Bag contains no loose paper
8 Re-read the current permitted-items list at source Night before Read on maa.org this season
9 Post nothing about the problems until the embargo lifts After the exam No photos, no threads, no group-chat post-mortem

One closing observation from watching this every January. The failures in this list are almost never defiance; they are momentum. A student wears the watch they always wear. A pencil case contains the compass it has contained since September. A parent, wanting to help, offers to handle registration. A student who has just spent forty minutes on twenty-five questions wants, quite reasonably, to talk about them. Every one of those is an ordinary human reflex, which is precisely why it needs a checklist rather than good intentions — and why the checklist gets run the night before, when there is still time to act on it.

If you are still choosing where to sit, that decision governs almost everything above: the day inside the window, the identity of the competition manager and proctor, and the arrangements on the morning. Start there, using the 2026-27 in-person registration guide, and confirm every rule quoted on this page against maa.org before you rely on it.

Q: Can my child wear a smartwatch during the AMC 8?
No. Smartwatches are on the MAA’s prohibited list along with phones and other electronic devices. Remove it the night before.

Q: Can I register my own child for the AMC 8?
No. Registration is handled by a competition manager, and the MAA states a parent or guardian of a candidate may not register the competition.

Q: May we discuss the problems in a WeChat group after the exam?
Not until the embargo lifts — 8 a.m. ET on the day after the competition period ends. Other students may not have sat yet.

Q: Should we bring our own scratch paper?
No. Blank scratch paper is provided by a teacher at the site, and graph paper is prohibited. Bring pens, pencils, a ruler and an eraser.
