📚 Preventing Mobile Phones from Entering the Exam Hall: Operational Guidance for Exams Officer | 防止手机进入考试场地：考试官员操作指南
A single phone buzzing in a silent exam hall can invalidate an entire cohort’s results, trigger a months-long malpractice investigation, and cost a centre its reputation. Yet most phone incidents are not the work of determined cheats; they are operational failures at the perimeter. This guide sets out a practical, defensible system that exams officers, heads of centre and invigilators can implement before, during and after every session.
寂静考场里一声手机震动，就可能让整批考生的成绩作废、引发长达数月的舞弊调查，并让一个考试中心声誉受损。然而大多数手机事故并非蓄意作弊者所为，而是考场外围的操作失误。本文提供一套实用且可辩护的体系，供考试官员、中心负责人和监考人员在每场考试前、中、后落地执行。
1. Why Phone Presence Is a Systemic Risk, Not Just Cheating | 为什么手机在场是系统性风险而不只是作弊
The risk is not limited to a candidate looking up an answer. A camera phone can photograph a live question paper within minutes of the start, and an image posted online can reach thousands of candidates before the session ends. That turns a local incident into a national security breach and may force an awarding organisation to replace or re-grade a paper.
风险并不限于考生查答案。带摄像头的手机可以在开考数分钟内拍下正在使用的试卷，图片上传网络后，可能在考试结束前就传播给成千上万名考生。这会把一起本地事件升级为全国性试题泄露，并可能迫使颁证机构换卷或重新评分。
Phones also create secondary risks: alarms and notifications disrupt concentration, lost or stolen devices generate safeguarding and liability complaints, and disputes over whether a device was switched off consume disproportionate staff time. Treat phone control as a whole-venue security function, not a disciplinary afterthought.
手机还带来次生风险：闹钟与通知打断考生注意力；设备遗失或被盗会引发安全保护与责任投诉；关于”是否已关机”的争议则消耗大量员工时间。应把手机管控视为整个考场的安保职能，而非事后的纪律问题。
2. The Regulatory Baseline: What the Rules Actually Say | 监管基线：规则究竟如何规定
In the UK, JCQ’s Instructions for Conducting Examinations (ICE) require that mobile phones and other unauthorised electronic devices must not be brought into the examination room, and that a candidate found in possession of such a device may be subject to malpractice procedures regardless of whether it was used. Ofqual’s General Conditions of Recognition require awarding organisations to have effective arrangements to prevent, detect and investigate malpractice.
在英国，JCQ 的《考试实施须知》（ICE）要求，手机及其他未经授权的电子设备不得带入考场；一旦发现考生持有此类设备，无论是否使用，都可能进入舞弊处理程序。Ofqual 的《认可通用条件》则要求各颁证机构建立有效机制以预防、发现和调查舞弊行为。
International boards follow the same logic. Cambridge International’s handbook and the IB’s academic integrity policy both place the primary duty on the head of centre and require candidates to surrender all electronic devices on entry. Always confirm the current wording for your board, because sanctions, permitted exceptions and reporting forms are updated each series.
国际考试局遵循同样逻辑：剑桥国际的考试手册与 IB 的学术诚信政策均把首要责任放在中心负责人身上，并要求考生在入场时交出所有电子设备。请务必核对你所属考试局的最新措辞，因为处罚措施、允许的例外情形和报告表格每考季都会更新。
3. Risk Assessment Before the Exam Day | 考前风险评估
Start with a written risk assessment that scores each entry point and each session. A simple model is risk as likelihood multiplied by severity:
风险 = 发生可能性 × 后果严重性
R = L × S
A 600-candidate morning session with two entrances and no screening scores far higher than a 12-candidate afternoon session in one room. Use the score to allocate staff, not to justify doing nothing.
一场 600 人、两个入口且无筛查的上午考试，其风险评分远高于一个房间内 12 人的下午考试。应据此分数配置人力，而不是用来解释”无需作为”。
- Map every route into the hall, including fire exits, service corridors and toilets.
- List peak arrival windows and the queue length that each checkpoint can absorb per minute.
- Identify candidates with approved access arrangements who legitimately carry a device.
- Note weather and waiting conditions, since outdoor queues push candidates to keep phones in hand.
- 绘制进入考场的所有路线，包括消防通道、员工走廊和洗手间路径。
- 列出抵达高峰时段，以及每个检查点每分钟可消化的排队长度。
- 识别经批准可合法携带设备的考生（如特殊考试安排）。
- 记录天气与等候条件，因为露天排队会促使考生把手机拿在手上。
Estimate throughput before you commit to a design:
T = (n × t) ÷ c
Where n is candidate numbers, t is seconds per check and c is the number of active channels. If T exceeds the arrival window, add channels rather than shortening the check.
其中 n 为考生人数，t 为每人检查秒数，c 为同时开放的检查通道数。若 T 超过入场时间窗口，应增加通道，而不是压缩检查时间。
4. Layered Screening at the Venue Perimeter | 场地外围的分层筛查
Design three concentric checkpoints so no single failure is fatal. Layer one is the outer perimeter, where signage and staff prompt voluntary surrender. Layer two is the building threshold, where bags are opened and devices collected. Layer three is the room door, where a final visual check catches late arrivals and returns from the toilet.
设计三个同心检查点，使任何单一环节失效都不致命。第一层是外围，通过标识与人员引导考生主动交出手机；第二层是楼宇入口，开包检查并收集设备；第三层是考场门口，用最终目视检查捕捉迟到者与如厕返回者。
| Layer | Location | Action | Owner |
| 1 | Outer perimeter / gate | Signage, verbal reminder, surrender point | Front-of-house staff |
| 2 | Building threshold | Bag check, tagging, secure storage | Invigilators |
| 3 | Room door | Final check, pocket and wrist check request | Lead invigilator |
Layered screening multiplies reliability. If each layer detects a device with independent probability p, the chance of missing it across n layers is:
分层筛查能成倍提升可靠性。若每一层独立发现设备的概率为 p，则 n 层全部漏检的概率为：
P(miss) = (1 − p)ⁿ
Three layers each detecting 60% of devices reduce the miss rate from 40% to about 6%. That is the mathematical case for investing in the perimeter.
若三层各有 60% 的发现率，漏检率将从 40% 降至约 6%。这就是投资于外围管控的数学依据。
5. Clear Notices and a Spoken Declaration | 清晰的告示与口头声明
Candidates cannot comply with a rule they have not read. Notices must state, in plain language, that phones, smart watches, earbuds and any device capable of storing or transmitting data are prohibited, that possession alone constitutes malpractice, and that devices must be surrendered before entry.
考生无法遵守一条自己没读过的规则。告示须用平实语言说明：手机、智能手表、无线耳机以及任何可存储或传输数据的设备均被禁止；仅”持有”即构成舞弊；设备必须在入场前交出。
Reinforce the notice with a standard spoken statement delivered by the lead invigilator before candidates are seated. Keep the wording identical every session so that staff cannot improvise and candidates cannot claim they were never warned.
在考生入座前，由主监考宣读统一的口头声明以强化告示。每场考试措辞完全一致，既避免工作人员临场发挥，也避免考生声称”从未被提醒”。
A model statement: “You must now switch off and hand in all phones, smart watches and earphones. If you are found with any such device after this point, it will be reported as malpractice, even if it is switched off and even if you did not use it.”
示例声明：”请现在关闭并交出所有手机、智能手表和耳机。此时间点之后若被发现携带此类设备，即使已关机、即使未使用，也将被作为舞弊上报。”
6. Secure Storage and Chain of Custody | 安全存放与保管链
Collection is only as strong as the storage behind it. Use numbered, sealable pouches or tagged bags so that each device can be traced to one candidate and one seat. Record the device type and the tag number on a log, and have two members of staff present whenever the storage room is opened.
收集环节的可靠性取决于背后的存放管理。使用带编号的可封口袋或有标签的袋具，使每台设备都能追溯到具体考生与座位。在记录表上登记设备类型与标签编号，并确保每次开启存放间时都有两名工作人员在场。
- Store devices in a locked room that is not the exam hall and not the candidates’ toilet route.
- Never leave the storage area unattended while it is open.
- Return devices only after the session ends and all scripts are collected and accounted for.
- Log any device that is unclaimed at the end of the day and hand it to the designated safeguarding lead.
- 将设备存放在上锁房间，该房间不得是考场，也不得位于考生通往洗手间的路线上。
- 存放区开启期间绝不离人。
- 仅在考试结束、所有答题卡收齐并核对无误后才归还设备。
- 当日无人认领的设备须登记，并交由指定的安全保护负责人处理。
7. Training Invigilators to Ask, Not Accuse | 培训监考人员”请求”而非”指责”
Most confrontations are caused by tone, not by policy. Train staff in a short, neutral script: state the request, offer the pouch, thank the candidate. Avoid accusatory phrasing such as “Are you hiding something?” which escalates a routine check into a dispute.
大多数冲突源于语气而非政策。应为员工训练一套简短中立的脚本：说出请求、递上封口袋、感谢配合。避免”你是不是藏了东西？”这类指责性措辞，它会把例行检查升级为争执。
Cover the following in every pre-series briefing:
每次考前系列培训应覆盖以下内容：
- What the rule says, word for word, and why possession alone is a breach.
- How to request a pocket check politely, including the option of a private area.
- What staff may and may not do, specifically that they must not physically search a candidate.
- How to summon the lead invigilator without raising their voice or drawing attention.
- How to record an incident on the spot, with time, seat number and witnesses.
- 规则的原文措辞，以及为何”仅持有”即构成违规。
- 如何礼貌地请求检查口袋，包括提供私密区域检查的选项。
- 员工可以做与不可以做的事，特别是不得对考生进行人身搜查。
- 如何在不提高音量、不引起注意的情况下请来主监考。
- 如何当场记录事件，包含时间、座位号与见证人。
8. Escalation Protocol for Suspected Devices | 疑似设备的升级处置流程
Define four tiers in advance so that nobody has to improvise under pressure. Tier one is a visible device before entry, resolved by surrender. Tier two is a device detected after seating, resolved by removal and an incident report. Tier three is suspected use during the exam, requiring removal without disturbing others. Tier four involves recording, transmission or external contact, and requires immediate notification of the head of centre.
提前定义四个层级，使任何人都无需在压力下临场决断。第一级：入场前发现可见设备，交出即可。第二级：入座后发现设备，移除并撰写事件报告。第三级：疑似考试中使用，需在不影响他人的情况下移除。第四级：涉及拍摄、传输或对外联络，须立即通知中心负责人。
| Tier | Trigger | Immediate action | Notification |
| 1 | Device visible before entry | Request surrender, tag, store | None |
| 2 | Device found after seating | Remove quietly, seat candidate apart, log | Lead invigilator |
| 3 | Suspected use during exam | Remove, allow candidate to continue without device | Exams officer |
| 4 | Recording or transmission suspected | Seal device, preserve evidence, do not delete | Head of centre and awarding body |
9. Malpractice Reporting and Evidence Handling | 舞弊上报与证据处理
Report every confirmed case, even where you believe no advantage was gained. Awarding organisations look for patterns, and an unreported device found in October may explain an anomaly in June. Use the board’s official malpractice form and attach the seating plan, the invigilator’s statement and any witness accounts.
每一例已确认的案件都要上报，即使你认为考生并未因此获益。颁证机构需要识别模式，十月未上报的发现可能正是六月异常情况的原因。使用考试局官方的舞弊表格，并附上座位表、监考声明及证人陈述。
Handle the device itself with care. Do not delete photographs, do not browse the candidate’s messages, and do not read out personal content in front of others. Photograph the device in place if the board requests it, place it in a sealed evidence bag, and record who handled it and when. Personal data protection law applies to candidates as much as to anyone else.
设备本身也须谨慎处理：不要删除照片，不要翻看考生信息，不要在他人面前朗读个人内容。若考试局要求，可在原位拍摄设备，随后放入密封证物袋，并记录经手人与时间。个人数据保护法同样适用于考生。
10. Technology Aids and Their Limits | 技术辅助手段及其局限
Handheld metal detectors are cheap, fast and effective for large metallic objects, but they miss phones in a bag of keys and coins, and they require consistent use to avoid the appearance of profiling. Walk-through detectors improve throughput but need calibration and a power source.
手持金属探测器便宜、快速，对大型金属物体有效，但在装满钥匙和硬币的包里可能漏检手机，且必须一致使用，以免给人”选择性检查”的印象。通道式探测器提升通行效率，但需要校准与电源。
Lockable phone pouches are effective when candidates keep them and are opened by staff only at the exit, but they add cost and require a robust unlock procedure. Signal jamming is illegal in many jurisdictions, including under the UK’s wireless telegraphy legislation, and must never be installed without written legal advice. Screening always beats blocking.
可锁手机袋在”考生自行保管、仅在出口由工作人员开启”时有效，但会增加成本并需要严谨的开锁流程。信号屏蔽在许多司法辖区属违法（包括英国无线电通信相关立法），未经书面法律意见绝不可安装。筛查始终优于屏蔽。
11. Accessibility, Dignity and Special Considerations | 无障碍、尊严与特殊考量
A zero-tolerance policy must still be applied with judgement. Some candidates carry medically approved devices such as insulin monitors or hearing aids, and some carry a school-issued device under an approved access arrangement. Record these approvals in advance and give those candidates a discreet pass so they are not repeatedly challenged.
零容忍政策仍需结合判断执行。部分考生携带经医疗批准的设备，如血糖监测仪或助听器；也有考生依据获批的特殊考试安排携带学校配发设备。应提前登记这些批准，并向相关考生发放低调通行凭证，避免其反复被质疑。
Be mindful of religious and cultural practice, of candidates who are neurodivergent and find physical proximity difficult, and of privacy when a check requires emptying pockets. Offer a screened area and a same-gender staff member where requested. A rule enforced without dignity breeds concealment, which is the opposite of what you want.
注意宗教与文化习惯，体谅对近距离接触不适的神经多样性考生，并在需要清空口袋时保护隐私。可应要求提供遮挡区域与同性别工作人员。缺乏尊严的执法会催生隐瞒，而这与你的目标恰好相反。
12. Post-Exam Review and Continuous Improvement | 考后复盘与持续改进
Close the loop after every session. Record the number of devices surrendered, the number detected at each layer, the number of incidents, and the average checkpoint time. These four numbers tell you whether the system is working and where to spend next term’s budget.
每场考试后都要闭环复盘。记录交出的设备数量、各层发现的设备数量、事件数量以及平均检查用时。这四个数字能告诉你体系是否有效，以及下学期的预算该投向何处。
A useful efficiency indicator is the device detection rate per layer:
一个有参考价值的效率指标是各层设备发现率：
Detection rate = (devices found ÷ devices present) × 100%
If layer three is consistently finding more devices than layer two, your threshold screening is too weak or too slow. If layer one finds almost nothing while layer three finds many, candidates are not reading the signage. Review, adjust, retrain, and record the change so that next series starts from a stronger baseline.
若第三层持续比第二层发现更多设备，说明入口筛查过弱或过慢；若第一层几乎无所获而第三层收获颇多，说明考生根本没看告示。复盘、调整、再培训，并记录变更，使下一考季从更高的基线起步。
