📚 Authorised vs Unauthorised Absence in Attendance Statistics | 出勤统计里的授权缺勤与非授权缺勤如何区分
Every school register contains two kinds of absence that look identical on a raw list of names but behave completely differently in the data: absence the school has permitted, and absence it has not. Getting the boundary right is not a clerical nicety. It determines the attendance rate a school publishes, the intervention a form tutor starts, the letter a parent receives, and in some jurisdictions whether a penalty is issued at all.
每一份点名册上都存在两种看起来一样、但在数据中表现完全不同的缺勤：学校许可的缺勤，和学校不许可的缺勤。把这条界线划准绝不是文书上的小事。它决定了学校公布的出勤率、班主任启动的干预措施、家长收到的通知信，在某些司法管辖区甚至决定了是否会被处以罚款。
1. Why the Distinction Matters | 为何这一区分至关重要
An attendance statistic is only meaningful if the categories behind it are applied consistently. If one teacher codes a term-time family trip as authorised and another codes the same trip as unauthorised, the school's published figures become an artefact of staffing rather than a measure of pupil behaviour. That is why almost every attendance framework separates absence into an authorised stream and an unauthorised stream, and reports them as two separate rates rather than one combined number.
只有当缺勤背后的分类被一致地应用时，出勤统计数据才有意义。如果一位老师把学期中的家庭旅行记为授权缺勤，另一位老师把同样的旅行记为非授权缺勤，学校公布的数字就变成了师资分配的产物，而不是学生行为的度量。正因如此，几乎所有出勤管理框架都把缺勤拆成"授权"与"非授权"两条线，并作为两个独立的比率来报告，而不是合成一个数字。
The two streams also carry different consequences. Authorised absence normally triggers support: a welfare check, a referral to pastoral care, a conversation about workload. Unauthorised absence normally triggers escalation: a formal letter, a meeting, an attendance panel, and in England the possibility of a penalty notice under section 444 of the Education Act 1996. Mixing them up means either punishing illness or ignoring truancy.
这两条线带来的后果也不同。授权缺勤通常触发的是支持：福利回访、转介给关怀团队、关于学业负担的谈话。非授权缺勤通常触发的是升级处理：正式信函、面谈、出勤听证会，在英格兰还可能依据《1996 年教育法》第 444 条发出罚款通知。把二者搞混，意味着要么惩罚生病的学生，要么对旷课视而不见。
2. Core Definitions | 核心定义
Authorised absence is a session (half-day) in which a pupil is not present, the reason for the absence is known to the school, and the school has decided that the reason is acceptable. The key words are "the school has decided". Authorisation is an institutional act, not a parental declaration.
授权缺勤（authorised absence）指某个"课时单元"（session，即半天）学生缺席，缺席原因学校已知，并且学校判定该原因可以接受。关键词是"学校已判定"。授权是一种机构行为，不是家长的声明。
Unauthorised absence is a session in which a pupil is not present and either no acceptable reason has been provided, or a reason has been provided but the school has judged it insufficient. This includes cases where the reason is known perfectly well — an unauthorised term-time holiday is not a mystery, it is simply not permitted.
非授权缺勤（unauthorised absence）指某个课时单元学生缺席，且要么未能提供可接受的理由，要么提供了理由但学校判定其不充分。这包括原因其实一清二楚的情形——未经批准的学期中休假并不是什么谜团，它只是不被许可。
Two boundaries are worth stating explicitly. First, a session that is not counted at all — for example a school closure day or a pupil not on roll — is neither authorised nor unauthorised; it is excluded from the denominator. Second, an "approved educational activity" such as a supervised sports fixture or a field trip is normally counted as present, not as authorised absence, even though the pupil is physically off site.
有两条边界需要明确说明。第一，完全不计入统计的课时单元——例如学校停课日，或学生当时并不在册——既不属于授权缺勤也不属于非授权缺勤，它被排除在分母之外。第二，诸如有人监管的体育比赛或实地考察这类"经批准的教育活动"，即便学生人不在校内，通常也计为出勤，而不是授权缺勤。
3. The Attendance Code Framework | 缺勤代码体系
Most systems operationalise the distinction through a small alphabet of codes keyed into the register. England's Department for Education code set is the most widely copied model, and international and independent schools frequently mirror it even when they are not legally bound by it. The codes matter because the statistics are calculated by aggregating codes, not by re-reading teachers' notes.
大多数系统通过一小套录入点名册的代码字母来落实这一区分。英格兰教育部（DfE）的代码集是被复制最广的模板，即便国际学校和私立学校在法律上不受其约束，也常常照搬。代码重要，是因为统计数据是通过汇总代码算出来的，而不是靠重读老师的备注。
| Code | Meaning | Category | Counts in denominator? |
|---|---|---|---|
| / and \ | Present in the AM / PM session | Present | Yes |
| L | Late arrival before the register closed | Present | Yes |
| B, P, V, W | Approved off-site educational activity, visit, work experience | Present | Yes |
| I | Illness | Authorised | Yes |
| M | Medical or dental appointment | Authorised | Yes |
| R | Religious observance | Authorised | Yes |
| H | Leave of absence granted by the school | Authorised | Yes |
| S, J | Study leave; approved leave for an interview or similar | Authorised | Yes |
| C, T | Exceptional circumstances; traveller absence | Authorised | Yes |
| E | Excluded from school | Reported as authorised in most frameworks | Yes |
| N | No reason yet provided | Unauthorised (provisional) | Yes |
| O | Absent without authorisation | Unauthorised | Yes |
| G | Leave of absence refused by the school | Unauthorised | Yes |
| U | Arrived after the register closed | Unauthorised | Yes |
| # | School closed to pupils | Not counted | No |
| X, Y, Z | Not required to be in school; unable to attend due to exceptional circumstances; not on roll | Not counted | No |
Two features of this table drive most real-world arguments. First, the "not counted" codes sit outside both categories, so a missing # entry silently depresses the attendance rate. Second, N is a placeholder that begins life as unauthorised and can only move into the authorised column if a school makes an active, recorded decision to move it.
这张表有两个特征引发了大多数现实中的争论。第一，"不计入"代码处在两个类别之外，所以漏填一次 # 会悄悄压低出勤率。第二，N 是一个占位符，它一出生就在非授权栏，只有学校做出主动且有记录的改码决定，才可能被移入授权栏。
4. Authorised Absence in Practice | 授权缺勤的实际情形
Authorised absence covers reasons that the school accepts as legitimate obstacles to attendance. The categories below are the ones that appear most often in policy documents and inspection frameworks.
授权缺勤涵盖学校认为构成正当出席障碍的理由。以下类别是政策文件与督导框架中出现频率最高的。
- Illness, including mental health conditions where the school has accepted the impact on attendance.
- Medical, dental and other health appointments that cannot reasonably be scheduled outside school hours.
- Religious observance on a day the pupil's faith requires it.
- Bereavement, family crisis, or a documented safeguarding or welfare situation.
- Leave granted in advance following a written request, where the school judges the circumstances exceptional.
- Exclusion, which is recorded separately but usually reported within the authorised stream.
- 疾病，包括学校已认可其对出勤确实造成影响的心理健康问题。
- 无法合理安排在课余时间的医疗、牙科及其他健康就诊。
- 学生所属信仰要求其遵守的宗教节日。
- 丧亲、家庭危机，或有记录的保障与福利情形。
- 在收到书面申请后事先批准的事假，且学校判定情形属于"特殊情况"。
- 停学（exclusion），单独记录，但通常在报表中归入授权栏。
Notice what these have in common: each one is documented, each one is time-limited, and each one has passed through a decision point. A school that codes illness as authorised without ever asking whether the pattern of illness is itself a concern has complied with the letter of the framework but missed its purpose.
注意它们的共同点：每一项都有记录、都有时间限制、都经过了一个决策节点。如果学校把疾病一律记为授权缺勤，却从不追问"这种生病模式本身是否值得担忧"，那就只是符合了框架的字面要求，而错过了它的用意。
5. Unauthorised Absence in Practice | 非授权缺勤的实际情形
Unauthorised absence is not the same as unexplained absence, although unexplained absence falls inside it. The category is defined by the absence of permission, not by the absence of information.
非授权缺勤不等于"无法解释的缺勤"，尽管无法解释的缺勤属于其中。这一类别由"缺少许可"来定义，而不是由"缺少信息"来定义。
- Truancy: the pupil is absent, the parent believes the pupil is in school, and no permission exists.
- Term-time holiday where leave was requested and refused, or where no request was ever made.
- Absence where the reason given is judged insufficient - for example, oversleeping, shopping, or a family outing.
- Absence where no reason has been provided at all and the follow-up window has expired.
- Late arrival after the register has closed, recorded as U for that session.
- Absence where a parent has notified the school but explicitly refuses to seek authorisation, or where the notification itself is retrospective and uncorroborated.
- 旷课：学生缺席，家长以为学生在校，且不存在任何许可。
- 学期中休假，且请假申请已被拒绝，或根本从未提出申请。
- 给出的理由被判定不充分的缺勤——例如睡过头、购物、家庭出游。
- 完全未提供理由、且跟进期限已过的缺勤。
- 点名册关闭后才到校，该课时单元记为 U。
- 家长已通知学校但明确拒绝申请授权，或通知本身属于事后补充且无法佐证。
A common source of error is the assumption that a telephone call from a parent automatically authorises an absence. It does not. A call transfers information to the school; the school then decides. This is why attendance policies almost always use the phrase "the school may authorise" rather than "parents may authorise".
一个常见的错误是假设家长打来电话就自动完成了授权。事实并非如此。电话只是把信息传递给学校，随后由学校做决定。这就是为什么出勤政策几乎总是写"学校可以授权"，而不是"家长可以授权"。
6. The Grey Zone: Illness, Term-Time Leave and Exceptional Circumstances | 灰区：疾病、学期中休假与特殊情况
The hardest cases are not truancy; they are the ones everyone agrees are real but nobody agrees are authorised. Three grey zones account for most disputes.
最棘手的案例不是旷课，而是那些所有人都承认确有其事、却没有人同意应予授权的案例。三个灰区涵盖了绝大多数争议。
Grey zone one: illness without evidence. Short, self-certified illness is normally accepted. But when a pupil's illness absence climbs past a threshold — commonly around 10% of sessions — schools increasingly ask for medical evidence, and continued absence without it may be reclassified. This is not a judgement about whether the child is ill; it is a judgement about whether the school can continue to authorise on the evidence available.
灰区一：无证据的疾病。短期的自我申报病假如通常会被接受。但当学生的病假缺勤超过某个阈值——通常在占总课时 10% 左右——学校会越来越多地要求提供医疗证明，若持续缺勤而无证明，可能被重新归类。这不是在判断孩子是否生病，而是在判断学校能否在现有证据下继续授权。
Grey zone two: term-time leave. Most frameworks allow leave only in exceptional circumstances, and define exceptional narrowly — a close family bereavement abroad, a once-in-a-lifetime religious pilgrimage, a deployment or relocation that cannot be moved. Cost of travel, cheaper flights, and family convenience are routinely named as not exceptional. If leave is granted, the days are authorised; if it is refused and the pupil goes anyway, the same days become G.Published by TutorHao | Exam Prep Revision Series | aleveler.com
