The 2026 examination series marks a significant turning point for IGCSE Engineering students following the Edexcel specification. Pearson has released a fully updated qualification (4ET1), replacing the previous code 4ET0, for first teaching from September 2024 and first assessment in June 2026. This revision brings fresh emphasis on practical engineering skills, digital design tools, and sustainable thinking. Understanding these changes early is essential for teachers, tutors, and learners aiming for top grades in the new 9–1 system.
2026 年考试季是修读 Edexcel IGCSE 工程课程的学生面临的重要转折点。培生已发布全新修订的资质证书（课程代码 4ET1），取代此前的 4ET0，并从 2024 年 9 月开始首次教学，2026 年夏季进行首次正式考试。本次修订更加强调实践工程技能、数字化设计工具以及可持续思维。尽早掌握这些变化，对于希望在全新 9–1 等级体系中斩获高分的学生、教师和辅导者而言至关重要。
1. New Specification Code and First Assessment Series | 新课程代码与首次考试系列
The outgoing specification 4ET0 will have its final assessment opportunity in the 2025 series, after which the new 4ET1 specification takes over. First examination for 4ET1 is set for June 2026, with a single tier of entry covering grades 9–1. This change aligns Edexcel International GCSE Engineering with other updated subjects, ensuring a modern and rigorous curriculum.
旧版课程 4ET0 的最后一次考试机会将于 2025 年系列结束，此后新版 4ET1 规格正式生效。4ET1 的首考时间安排在 2026 年 6 月，采用单一层级报考，成绩覆盖 9–1 等级。这一变化使 Edexcel 国际 GCSE 工程学科与其他已更新的科目保持一致，确保课程内容既现代又严谨。
Students registered under the old specification must ensure they complete all units by the 2025 deadline; resit opportunities will follow the new structure from 2026 onwards. The new qualification code also updates the entry fees and administrative processes, so schools should check with their exams officer for the latest arrangements.
注册旧版课程的学生必须确保在 2025 年截止日期前完成所有单元；从 2026 年起，补考将遵循新结构进行。新课程代码同时更新了报名费用和行政流程，因此学校应联系考试专员核查最新安排。
2. Restructured Assessment Components | 重新设计的评估模块
The most visible change is the split into two mandatory components: Unit 1 – Engineering Principles (written examination, 60% of total marks) and Unit 2 – Practical Engineering Applications (practical examination, 40%). Unit 1 is a 2-hour paper with 100 marks, assessing core theory. Unit 2 is a practical task set by Pearson, carried out under controlled conditions, marked by the centre and externally moderated. This replaces the earlier coursework model where students completed a design-and-make project over an extended period.
最显眼的变化是划分为两个必修模块：单元一“工程原理”（笔试，占总成绩 60%）和单元二“工程实践应用”（实践考试，占 40%）。单元一是时长 2 小时、满分 100 分的卷面考试，考查核心理论知识。单元二是由培生命题的实践任务，在受控条件下完成，由学校评分并接受外部审核。这一模式取代了此前历时较长的“设计与制作”课程作业模型。
The shift towards a live practical examination means that all candidates attempt the same set of externally devised tasks, improving consistency. The practical exam will require candidates to demonstrate planning, manufacturing, testing, and evaluation skills within a fixed timeframe, typically completed over a series of supervised sessions.
转向统一的实践考试意味着所有考生将完成同样一套外部设定的任务，从而提高评分的公平性。实践考试要求考生在固定时间内展示规划、制造、测试和评价技能，通常在一系列受监督的课时中完成。
3. Updated Content Outline and Topic Additions | 内容大纲更新与新增主题
The 4ET1 syllabus retains core topics such as materials, mechanics, electronics, and design processes, but it also introduces contemporary content areas. Notably, there is new emphasis on intelligent systems and microcontrollers, including basic programming logic for embedded systems, sensors, and actuators. This reflects the increasing role of automation in modern engineering.
4ET1 课程大纲保留了材料、力学、电子学和设计流程等核心主题，同时也引入了紧跟时代的内容。最引人注目的是新增对智能系统与微控制器的强调，涵盖了嵌入式系统的基本编程逻辑、传感器和执行器等知识。这点反映了现代工程中自动化作用的日益增强。
Additionally, the specification incorporates engineering drawing standards with more explicit links to CAD (computer-aided design) techniques. Topics like 3D modelling, orthographic projection, and tolerancing are tied to practical tasks, enabling learners to produce digital prototypes. The table below summarises some of the key topic clusters:
此外，该规格还纳入了工程制图标准，并与 CAD（计算机辅助设计）技术建立了更明确的关联。三维建模、正投影和公差等主题与实践任务紧密结合，使学习者能够创建数字样机。下表概括了部分核心主题群：
| Topic Area 主题领域 | Focus in 4ET1 重点方向 |
| Materials & Properties 材料与性能 | Metals, polymers, composites; lifecycle analysis |
| Mechanical Systems 机械系统 | Forces, motion, energy efficiency calculations |
| Electronics & Control 电子与控制 | Programmable microcontrollers, input/output devices |
| Design & CAD 设计与计算机辅助设计 | Orthographic drawing, 3D modelling, dimensioning |
4. Enhanced Role of CAD/CAM in Practical Work | CAD/CAM 在实践操作中作用的提升
Practical engineering applications now integrate CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) as fundamental skills. Unlike the older specification where CAD might have been optional or superficial, Unit 2 tasks will require candidates to produce CAD models, generate toolpaths for CAM equipment such as laser cutters or 3D printers, and justify their digital choices.
工程实践应用如今将 CAD（计算机辅助设计）和 CAM（计算机辅助制造）作为基础技能进行整合。在旧版课程中，CAD 可能只是可选项或流于表面，而新版单元二任务将要求考生创建 CAD 模型，为激光切割机或 3D 打印机等 CAM 设备生成刀具路径，并解释其数字化选择的理由。
Centres will need to ensure access to appropriate software and CNC machinery. Popular packages like Fusion 360, TinkerCAD, or SolidWorks are mentioned as suitable tools. Learners should become comfortable with exporting files in standard formats (.stl, .dxf) and understanding how digital design translates into physical products. This shift not only aligns with industry expectations but also reduces waste by encouraging virtual prototyping before manufacturing.
学校将需要确保能够提供合适的软件和数控机床。官方提及 Fusion 360、TinkerCAD 或 SolidWorks 等常用软件都是适合的工具。学习者应当熟练输出标准格式文件（.stl、.dxf），并理解数字设计如何转化为实体产品。这一转变不但符合行业期望，还通过鼓励先虚拟打样再实际制造来减少浪费。
5. Strengthened Assessment Objectives (AO) Weighting | 评估目标及其权重强化
The distribution of Assessment Objectives has been recalibrated. In the new 4ET1 specification, AO1 (Knowledge and understanding) accounts for about 30–35%, AO2 (Application of knowledge) for 30–35%, and AO3 (Analysis and evaluation) for 30–40%. This marks a shift towards higher-order thinking, with more marks devoted to evaluating design solutions, manufacturing processes, and test data.
新规格对评估目标的分布进行了重新调整。在 4ET1 课程中，AO1（知识与理解）约占总分的 30–35%，AO2（知识应用）占 30–35%，而 AO3（分析与评价）则占 30–40%。这标志着向高阶思维的转变，更多分值将用于评价设计方案、制造过程和测试数据。
Unit 1’s written paper will feature extended response questions that demand critical analysis, such as comparing materials based on sustainability or justifying a manufacturing sequence. Unit 2’s practical write-up likewise requires evaluation of outcomes and modifications. Students must develop the ability to structure arguments, reference technical data, and propose improvements clearly.
单元一的笔试中将出现要求批判性分析的拓展回答题型，例如基于可持续性比较材料或论证制造工序。单元二的实践报告同样需要评价成果与修改方案。学生必须培养清晰组织论点、引用技术数据并提出改进建议的能力。
6. Explicit Maths and Science Skills Requirement | 明确的数学与科学技能要求
Edexcel has embedded a dedicated maths and science skills section in the new engineering specification. At IGCSE level, candidates are expected to perform calculations involving stress, strain, mechanical advantage, efficiency, and electrical quantities. The total maths demand constitutes about 20% of the marks across both units. Example formulas include:
Edexcel 在全新工程规格中专门嵌入了数学与科学技能的要求。在 IGCSE 阶段，考生需要完成应力、应变、机械利益、效率以及电学量等相关计算。两个单元合计约 20% 的分数将涉及数学应用。示例公式包括：
Stress σ = F / A
Mechanical advantage MA = Load / Effort
Symbols such as σ (sigma) for stress, ε (epsilon) for strain, and Ω (ohm) for resistance must be used correctly. Data interpretation from graphs and tables is also assessed. Learners should practise converting units, using standard form, and calculating percentage errors in practical contexts.
考生需要正确使用应力符号 σ、应变符号 ε 和电阻符号 Ω。读取图表和表格中的数据同样会被考查。学习者应当多加练习单位换算、标准形式表示以及在实践情境中计算百分误差。
7. Emphasis on Sustainability and Lifecycle Thinking | 可持续性与生命周期思维的强调
Environmental factors now run as a continuous thread throughout the 4ET1 content. Topics such as material selection require students to compare carbon footprints, recyclability, and end-of-life disposal. The Six Rs (Reduce, Reuse, Recycle, Repair, Refuse, Rethink) are integrated into design and evaluation tasks. In the written exam, questions may explicitly ask learners to suggest ways of minimising ecological impact in a given product.
环境因素如今贯穿 4ET1 全部内容。在材料选择等主题中，要求学生对碳足迹、可回收性和废弃处置进行比较。六项环保原则（减少、重用、回收、修复、拒绝、反思）被融入到设计和评价任务中。在笔试中，考题可能会明确要求考生针对给定产品提出最小化生态影响的方法。
This trend mirrors global shifts in engineering education, and demonstrates that awarding organisations are responding to industry’s demand for sustainably-minded graduates. Case studies on biodegradable polymers, lightweight structures, and energy-efficient circuits are likely to feature prominently in future papers.
这一趋势反映了全球工程教育的变化，也表明考评机构正响应业界对具备可持续思维人才的渴求。关于可生物降解聚合物、轻质结构和节能电路的案例研究，很可能在未来的试卷中频繁出现。
8. Changes in Controlled Assessment Conditions | 受控评估条件的变化
Unit 2’s practical examination is conducted under controlled assessment conditions, which are more structured than the previous coursework. Tasks are released by Pearson at a set date, and students must complete planning, making, testing, and evaluation during supervised sessions. Teachers can provide feedback only within prescribed limits, and authentication forms must be signed to confirm the work is the candidate’s own.
单元二的实践考试以受控评估的方式进行，其结构比以往课程作业更为严谨。任务由培生在指定日期发布，学生必须在受监督的课时内完成规划、制作、测试和评价。教师只能在规定范围内提供反馈，并且必须签署真实性声明表格，确认作品由考生独立完成。
This tighter control reduces the risk of malpractice and ensures fairer comparison between centres. For students, it means time management and prior preparation become critical. Practising timed practical exercises and mock write-ups from sample tasks will be an essential part of revision programmes.
这种更严格的管控降低了舞弊风险，并确保各学校之间有更公平的比较。对学生而言，这意味着时间管理和预先准备变得至关重要。在计时条件下练习实践操作，并根据样题进行模拟报告写作，将成为复习计划的重要组成部分。
9. Grade Boundary and Performance Trends | 等级边界与成绩走向预测
As with any new specification, grade boundaries in the first 2026 series are likely to be set generously, reflecting that teachers and learners are still adapting. Historically, when Edexcel introduced refreshed IGCSEs, the proportion of grades 7–9 was comparable to previous years after standardisation. However, because the practical component is now a live examination rather than coursework, centres may initially find the distribution of high marks slightly narrower.
与任何新规格一样，2026 年首次考试的等级边界很可能会设定得相对宽松，以反映教师和学生尚处于适应阶段。从历史来看，Edexcel 在推出更新版 IGCSE 时，经过标准化处理后，7–9 等级的比例与往年相当。然而，由于实践部分现在变为统一考试而非课程作业，各中心在高分段的人数分布最初可能会略窄。
Tutors and students should monitor the sample assessment materials (SAMs) and the first examiner’s report when it becomes available. Performance in mathematical applications and evaluation questions is expected to be a key differentiator for the top grades. Regular timed practice under exam conditions will help manage the pacing of both written and practical tasks.
辅导教师和学生应密切关注官方样题材料以及后续的首份考官报告。数学应用和评价类题目的表现，预计将成为拉开高分差距的关键。在模拟考试条件下进行限时练习，将有助于掌控笔试和实践环节的答题节奏。
10. Recommended Preparation Strategies | 推荐备考策略
Prepare for the 2026 IGCSE Engineering exam by integrating theory with hands-on practice. Build a bank of design examples and material properties. Use CAD software weekly to improve fluency. For the written paper, focus on command words like ‘justify’, ‘evaluate’, and ‘suggest’, which appear frequently in AO3 questions.
