Job description

Harrow School is situated in Harrow on the Hill in north-west London. The School is located on a 324-acre estate which encompasses much of Harrow on the Hill and is one of the best-known schools in the world. Around 837 boys study at Harrow and live in the School’s 12 boarding houses. Employees particularly value the School’s beautiful green estate, the positive working environment, and good relationships with their colleagues.

The School seeks to appoint a part-time teacher of Computer Science from September 2026. This role is fixed term with the possibility of extension, and includes eighteen 40-minute periods of teaching per week.

The Role:

The successful candidate will teach:

• CAIE A Level Computer Science (9618)
• CAIE IGCSE Computer Science (0984)
• Year 9 Computer Science

with flexibility in the working arrangement and the potential for increased teaching hours in the future.

Key Responsibilities:

Deliver engaging, well-structured, and challenging lessons in Computer Science across Key Stages 3 to 5.

Prepare boys for public examinations, ensuring strong academic outcomes.

Contribute to the development of departmental schemes of work and teaching resources.

Foster a positive learning environment that supports both academic progress and enthusiasm for the subject.

Support wider departmental and school activities, including co-curricular computer science and enrichment opportunities as appropriate.

Computer Science is one of the most dynamic and rapidly expanding departments in the School, playing a central role in equipping boys with the technical fluency and critical thinking skills needed to thrive in the digital world. The department’s forward-looking curriculum is both rigorous and creative, placing strong emphasis on problem-solving, innovation and hands-on experience from the outset.

In the Shell year (Year 9), boys begin with an introduction to cyber-safety, digital hygiene and touch[1]typing, alongside structured use of digital tools to support their broader academic progress. They then move on to a course in artificial intelligence, where they explore key theoretical concepts and real-world applications in machine learning. Programming is introduced through Python, with boys undertaking a range of ambitious projects including mathematical modelling, scientific analysis, and game development. Later in the year, they apply their skills in designing and programming intelligent robots capable of performing complex task.

In the Remove and Fifth Forms (Years 10 and 11), boys follow the CAIE IGCSE Computer Science course (0478). This builds on the strong foundation established in Shell and introduces a deeper study of algorithms, system architecture and software development. Practical work remains central: boys design and test their own programs, work with hardware such as Raspberry Pi and gaming systems, and complete an independent project in the summer between Remove and Fifth Form.

At A level, boys study the Cambridge International Computer Science syllabus, which provides a robust and intellectually demanding grounding in computational theory and software engineering. The course fosters creativity and precision in equal measure, with topics including data structures, systems design, programming paradigms and algorithmic analysis. Boys gain significant experience in developing software to solve real-world problems, preparing them for further study in fields such as Artificial Intelligence, Data Science, Cybersecurity and Engineering. A number of boys go on to study Computer Science at leading universities in the UK and overseas.
