📚 AQA Science May/June Series: 21 February Entry Deadline and 21 April Tier Change Window | AQA 科学 5/6 月考季：2 月 21 日报名截止与 4 月 21 日层级更改期限
For AQA science qualifications, centres must manage two fixed administrative dates in the May/June series: the entries deadline on 21 February and the free tier change deadline on 21 April. Missing these can lead to late fees or candidates being locked into the wrong tier.
对于 AQA 科学资格考试，各考试中心在 5/6 月考季必须管理两个固定行政日期：2 月 21 日的报名截止日期和 4 月 21 日的免费层级更改截止日期。错过这些日期可能导致逾期费用或考生被锁定在错误的层级。
1. Overview of the May/June Exam Series | 5/6 月考季概览
The May/June series is the main summer sitting for AQA GCSE and A-level science qualifications. Most centres submit entries between January and February, with the final date fixed on 21 February every year.
5/6 月考季是 AQA GCSE 和 A-level 科学资格考试的主要夏季考季。大多数考试中心在 1 月至 2 月间提交报名，最终日期固定为每年 2 月 21 日。
This fixed date applies regardless of the day of the week, so centres must plan internal deadlines earlier. For example, if 21 February falls on a Sunday, the entry window does not automatically extend.
该固定日期不受星期几影响，因此各考试中心必须提前规划内部截止日期。例如，如果 2 月 21 日是星期日，报名窗口也不会自动延长。
Schools and colleges running AQA science qualifications should treat this date as an absolute operational deadline, not a target to aim for on the day.
开设 AQA 科学资格的学校和学院应将该日期视为绝对的运营截止日期，而不是当天才完成的目标。
2. The 21 February Entries Deadline | 2 月 21 日报名截止日期
By 21 February, centres must have submitted all candidate entries for the May/June science papers. This includes GCSE Biology, Chemistry, Physics, Combined Science: Trilogy, and A-level sciences such as Biology, Chemistry and Physics.
截至 2 月 21 日，各考试中心必须提交所有考生参加 5/6 月科学试卷的报名。这包括 GCSE 生物、化学、物理、组合科学：三部曲，以及 A-level 科学学科，如生物、化学和物理。
The deadline applies to both initial entries and any amendments to candidate details made before the date. Once the deadline passes, AQA closes the standard entry window for the series.
该截止日期适用于初始报名以及在该日期前对考生信息所做的任何修改。一旦截止日期过去，AQA 将关闭该考季的标准报名窗口。
Centres that have candidates transferring from another centre or joining late must still ensure their entries are received by AQA before 21 February.
有从其他中心转来或晚加入的考生的考试中心，仍必须确保 AQA 在 2 月 21 日前收到他们的报名。
3. What Counts as a Complete Entry | 完整报名包括什么
A complete AQA science entry normally contains the candidate's personal details, the subject award code, and, for tiered GCSE papers, the chosen tier. Missing any element can cause the entry to be rejected.
完整的 AQA 科学报名通常包含考生的个人详细信息、科目认证代码，以及对于分层 GCSE 试卷所选择的层级。缺少任何一项都可能导致报名被拒绝。
Key components of a valid entry include:
有效报名的关键组成部分包括：
- Candidate name and date of birth | 考生姓名和出生日期
- Subject award code, such as 8464 for Combined Science: Trilogy | 科目认证代码，例如组合科学：三部曲为 8464
- Tier of entry for tiered GCSE papers, either Foundation or Higher | 分层 GCSE 试卷的报名层级，基础层或高级层
- Any access arrangements or special consideration requests | 任何考试便利安排或特殊考虑申请
Exams officers should verify each field against the centre's management information system before final submission.
考试官在最终提交前应逐一核对中心管理信息系统中的每个字段。
4. Late Entries and Late Fees | 逾期报名与逾期费用
If a centre misses the 21 February deadline, AQA may still accept late entries for a limited period, but late fees apply. The exact late fee depends on the qualification and the date of submission.
如果考试中心错过了 2 月 21 日的截止日期，AQA 仍可能在有限时间内接受逾期报名，但会收取逾期费用。具体逾期费用取决于资格类型和提交日期。
Late entry fees are charged per candidate and per qualification. For large cohorts, these charges can become significant very quickly.
逾期报名费按每名考生和每个资格收取。对于人数较多的考生群体，这些费用可能迅速累积成一笔不小的金额。
Repeated late entries can also trigger centre-level monitoring by the awarding body. AQA may ask for an explanation and, in serious cases, impose additional conditions on a centre.
反复逾期报名还可能触发考试局对考试中心的监控。AQA 可能要求作出解释，在严重情况下还会对考试中心施加额外条件。
5. Tiered Papers in GCSE Science | GCSE 科学的分层试卷
In AQA GCSE science, the tiered subjects are GCSE Biology, Chemistry, Physics and Combined Science: Trilogy. Each tiered paper has Foundation Tier, covering grades 1 to 5, and Higher Tier, covering grades 4 to 9.
在 AQA GCSE 科学中，分层科目包括 GCSE 生物、化学、物理和组合科学：三部曲。每份分层试卷分为基础层，覆盖 1 至 5 级，和高级层，覆盖 4 至 9 级。
Centres must choose the correct tier for each candidate at entry. The 21 April free tier change window gives centres a chance to review predicted performance before finalising.
各中心在报名时必须为每位考生选择正确的层级。4 月 21 日的免费层级更改窗口让中心有机会在最终确定前评估预测成绩。
A common error is entering a borderline candidate for Higher Tier without considering the risk of an unclassified result if they score below the minimum Higher Tier mark.
一个常见错误是在没有考虑未能达到高级层最低分数可能导致未分级结果的风险下，将边缘考生报入高级层。
6. The 21 April Free Tier Change Deadline | 4 月 21 日免费层级更改截止日期
Until 21 April every year, centres can change a candidate's tier of entry without charge. This applies only to tiered GCSE science qualifications, not to A-level sciences.
每年 4 月 21 日之前，各考试中心可以免费更改考生的报名层级。这仅适用于分层 GCSE 科学资格，不适用于 A-level 科学。
A typical change is moving a candidate from Higher to Foundation Tier after mock examinations, or promoting a strong candidate from Foundation to Higher.
典型的更改是在模拟考试后将考生从高级层调至基础层，或将表现优秀的考生从基础层提升至高级层。
Centres should use internal mock results and classwork evidence from March and early April to make these decisions. Waiting until the last day increases the risk of data entry errors.
各中心应利用 3 月和 4 月初的内部模拟考试成绩和课堂作业证据来作出决定。等到最后一天才操作会增加数据录入错误的风险。
7. Changing Tier After 21 April | 4 月 21 日后更改层级
After 21 April, tier changes are no longer free. AQA may still process a tier change in exceptional circumstances, but centres will be charged a fee and must provide justification.
4 月 21 日之后，层级更改不再免费。AQA 仍可能在特殊情况下处理层级更改，但考试中心需支付费用并提供理由。
In most cases, candidates are then locked into the tier chosen by the deadline. This means a candidate entered for Higher Tier cannot simply switch to Foundation on the day of the exam.
在大多数情况下，考生之后将被锁定在截止日期前选择的层级。这意味着报名高级层的考生不能在考试当天直接改为基础层。
If a centre believes a later tier change is essential, it should contact AQA immediately and be ready to submit supporting evidence from the candidate's subject teacher.
如果考试中心认为之后必须更改层级，应立即联系 AQA，并准备好提交考生任课教师的支持证据。
8. A-level Science: No Tier, But Same Entry Date | A-Level 科学：无层级但报名日期相同
AQA A-level Biology, Chemistry and Physics are linear, untiered qualifications. There is no Foundation or Higher Tier, so the 21 April tier change rule does not apply.
AQA A-level 生物、化学和物理是线性、不分层的资格。没有基础层或高级层，因此 4 月 21 日的层级更改规则不适用。
However, A-level science entries must still be submitted by the same 21 February deadline. This includes candidates taking AS and A-level units in the same series where applicable.
然而，A-level 科学报名仍须在同一个 2 月 21 日截止日期前提交。这包括在同一考季参加 AS 和 A-level 单元的考生（如适用）。
Centres sometimes forget that although A-level sciences do not require a tier choice, they still need accurate entry codes for each examined unit and optional practical endorsement.
各考试中心有时会忘记，尽管 A-level 科学不需要选择层级，但仍需要为每个考试单元和可选的实践认证输入准确的报名代码。
9. Centre Administration and Internal Deadlines | 考试中心管理与内部截止日期
Schools and colleges should set internal deadlines at least two weeks before the AQA deadline. This allows time for checking candidate details, collecting fees, and resolving data errors.
学校和学院应至少在 AQA 截止日期前两周设定内部截止日期。这样可以留出时间核对考生信息、收取费用并解决数据错误。
Exams officers should run entry reports from the centre's management information system and reconcile them with AQA records. Any mismatch must be corrected before the external deadline.
考试官应从中心的管理信息系统导出报名报告，并与 AQA 记录进行核对。任何不一致都必须在外部截止日期前予以更正。
It is also good practice to hold a short meeting with subject leaders in early February to confirm tier recommendations for all GCSE science candidates.
另一个良好做法是在 2 月初与学科负责人召开简短会议，确认所有 GCSE 科学考生的层级建议。
