O Level Sociology: Family, Education and Crime (Cambridge 2251)

This guide covers Paper 2 Family, Education and Crime, for Cambridge O Level Sociology 2251, Version 3, 2025–2027 series. Paper 2 covers three further named topics, and candidates answer questions on 2 of the 3 — unlike Paper 1, where Question 1 (Research Methods) is compulsory alongside a choice of one more.

Where this fits in 2251

Paper 2 turns from the foundational concepts and methods covered in Paper 1 to three specific social institutions and phenomena — the family, the education system, and crime and deviance — each examined through the lens of the research methods and sociological concepts Paper 1 introduces. Because candidates choose 2 of the 3 topics on this paper, it is possible to specialise, but the syllabus still expects candidates to be able to apply Paper 1’s research methods content to whichever two topics they choose, so Research Methods remains relevant preparation for this paper too, not just Paper 1.

Syllabus coverage

CAMBRIDGE O LEVEL SOCIOLOGY 2251 — PAPER 2 FAMILY, EDUCATION AND CRIME

• 2.1 Family — the different forms family takes across societies, the functions the family performs, and how family structures and roles are changing
• 2.2 Education — the role and functions of education in society, and factors affecting educational achievement
• 2.3 Crime, Deviance and Social Control — how crime and deviance are defined and measured, explanations for criminal and deviant behaviour, and the formal and informal methods societies use to control it

How to approach it

Because candidates answer on only 2 of these 3 topics, a practical revision strategy is to prepare all three to a reasonable standard early, then commit to genuinely deep revision on two closer to the exam — abandoning a topic too early risks being caught out if the exam’s specific questions on the other two are less comfortable than expected. For Family (2.1), strong answers move beyond describing the nuclear family as a fixed norm and can discuss real variation — extended families, single-parent families, and changing patterns such as smaller family size or delayed marriage — and can explain a function of the family (such as primary socialisation or economic support) with a specific example rather than naming the function alone.

Education (2.2) rewards being able to discuss more than one explanation for why some students achieve more than others — factors such as social class, parental attitudes, school resources and peer groups are all legitimate angles, and the strongest answers weigh more than one factor against each other rather than presenting a single cause as the whole explanation. A common error is treating educational achievement as explained entirely by one factor (usually the student’s own effort or ability) without engaging with the sociological factors the syllabus specifically asks about.

Crime, Deviance and Social Control (2.3) is often the most engaging topic to students but also where vague, common-sense answers replace sociological explanation most often — being able to name and briefly explain a specific sociological theory of why crime occurs (rather than simply describing what crime is), and to distinguish formal social control (police, courts, laws) from informal social control (family disapproval, peer pressure, community norms), is what this sub-topic actually tests. Measuring crime is also worth revising directly: official crime statistics have known limitations (such as under-reporting and differences in how offences are recorded), and being able to explain why the “true” crime rate may differ from recorded statistics is a frequently tested idea.

Across all three topics, the strongest preparation links back to Paper 1: practise suggesting which research method would suit studying a specific family, education or crime-related question, and why, since examiners reward candidates who treat the syllabus as one connected body of knowledge rather than three separate topics with no relationship to the methods content examined elsewhere.

Worked example: explaining educational achievement

A typical exam question asks candidates to explain why some students achieve more highly than others. A weak answer states “some students work harder than others” and stops there. A stronger answer identifies a specific sociological factor — for instance, that children from homes with more books, more parental involvement in homework, and more familiarity with the vocabulary and expectations schools use may enter education with an advantage sometimes described as cultural capital — and explains, in the candidate’s own words, the mechanism by which that factor plausibly affects achievement, rather than simply naming the factor. Where two factors are given in a question (for example, home background and school resources), the strongest answers weigh them against each other and reach a reasoned judgement about which matters more in a given case, rather than describing each in isolation.

Common mistakes to avoid

• Treating “the family” as a single fixed type rather than acknowledging genuine variation in family structure across societies and over time.
• Explaining educational achievement using only common-sense assumptions about effort or intelligence, without engaging any of the sociological factors the syllabus specifies.
• Describing what a crime is without explaining why it occurs — a definition is not, by itself, an explanation.
• Confusing formal social control (laws, police, courts) with informal social control (family, peers, community norms), or treating them as interchangeable rather than distinct mechanisms.
• Forgetting that official crime statistics have known limitations, and presenting recorded crime figures as if they were a complete and accurate picture of all crime that actually occurs.
