Two of the three assessment objectives in H505 concern evidence, and students conflate them more often than any other pair — with costly results. AO2 is the evaluation of contemporary sources: documents produced within the period studied, weighed for their value to a historical enquiry by their provenance, tone, purpose and context. AO3 is the evaluation of interpretations: the arguments historians advance, looking back, about how the past should be understood, weighed for how convincing they are against your own knowledge. The two skills work on different materials, ask different questions, and reward opposite reflexes — yet because both involve "reading a passage and judging it", the untrained eye blurs them, and a candidate who treats an interpretations extract as a source to be checked for reliability, or a contemporary source as a historian's argument to be agreed or disagreed with, forfeits marks in the two highest-density parts of the qualification. AO2 is examined in the UG1 source enquiry (and appears in the coursework where it draws on primary material); AO3 is examined in the UG3 interpretations question and, most extensively, in the coursework. Getting the distinction crystal-clear is therefore not an optional refinement but a precondition of competent performance across nearly half the qualification.
This lesson exists to make that distinction unmistakable. It has three tasks. First, to fix the conceptual difference — what a contemporary source is and what an interpretation is, and why they demand different treatment. Second, to teach the AO2 skill in full: the four-dimension method of evaluating a source's value for an enquiry, with a worked illustration. Third, to teach the AO3 skill in full: the evaluation of a historian's argument against evidence, deliberately setting provenance aside, with a worked illustration. Throughout, representative sources and extracts are paraphrased for teaching — characterised in our own words to model the skill, never presented as verbatim quotations from any real document or historian — so that you learn the method rather than memorise a passage. The two worked illustrations are chosen to sit side by side, so the contrast between the skills is visible in action.
The organising question is: what exactly distinguishes the evaluation of a contemporary source (AO2) from the evaluation of a historian's interpretation (AO3), and what precise moves does each reward? Keep it in view. The single most damaging error in H505's evidence questions is bringing the wrong skill to the wrong material.
By the end of this lesson you will be able to:
This lesson develops the two evidence skills of OCR H505: AO2 (analysis and evaluation of contemporary source material), examined in the Unit Group 1 source enquiry; and AO3 (analysis and evaluation of interpretations), examined in the Unit Group 3 interpretations question and, most substantially, in the Y100 coursework. It is a skills lesson: its content is the method of source evaluation and interpretation evaluation, not any single period. Within our own teaching sequence it follows the format-technique overview of Lesson 2 and precedes the coursework guide of Lesson 4, deepening the two evidence skills that Lesson 2 introduced at the level of examination format. This ordering is our own pedagogical decision.
For the exact question wording, mark allocations and band descriptors, always consult the official OCR H505 specification and its sample assessment materials rather than any paraphrase (refer to the official OCR specification for exact wording). All sources and extracts below are paraphrased for teaching and are not quotations from any real document or historian.
Everything in this lesson flows from one distinction, so it is worth stating with full precision before any technique. A contemporary source is a piece of evidence created within the period being studied — a speech, a letter, a decree, a diary, a newspaper report, a pamphlet — by someone who was, in some sense, there. It is a fragment of the past itself. An interpretation is a considered argument about the past, formed after the event by a historian (or occasionally another commentator) looking back, usually as part of a scholarly debate about how the period should be understood. It is not a fragment of the past but a reading of it. The difference in what they are dictates the difference in how you evaluate them.
| Contemporary source (AO2) | Interpretation (AO3) | |
|---|---|---|
| What it is | Evidence produced within the period — a fragment of the past | An argument about the past, formed later by a historian |
| Who made it | A participant, observer, or contemporary | A historian, looking back and reasoning about the evidence |
| The question you ask | "How useful is this for this enquiry?" | "How convincing is this argument?" |
| Your knowledge is used to… | Test and contextualise the source's claims | Test the argument — support it and qualify it on both sides |
| Provenance (who/when/why) is… | Central — it locates the source's value and limits | Set aside — you judge the argument, not the author's position |
| Bias / partiality is… | Often the source's greatest value (evidence of a view) | Irrelevant as "bias"; you weigh the reasoning, not the standpoint |
| The classic error | Summarising the source instead of judging its value | Judging by provenance, or agreeing/disagreeing personally |
The rows most worth dwelling on are the last three, because they name the opposite reflexes the two skills demand. On a contemporary source, provenance is central: who made it, when, from what position, and why, is exactly what tells you what the source is worth for an enquiry — and its partiality is often its greatest value, because a slanted source is superb evidence of a viewpoint, a mood, or a purpose (a hostile pamphlet is poor evidence of the facts it distorts but excellent evidence of the strength of the hostility). On an interpretation, by contrast, provenance is set aside: you are not asked who the historian was or when they wrote, but whether their argument stands up against the evidence — and "bias" is the wrong category entirely, because a historian's standpoint is not a defect to be deducted but simply the position from which they reason, and what you evaluate is the reasoning. Reaching for "the historian wrote during such-and-such a period, so is biased" on an AO3 question is the single most common cross-contamination, and it wastes the words that should test the argument. The disciplined student asks, on sight of any evidence passage: is this a fragment of the past (evaluate its value, provenance central) or a historian's argument about the past (evaluate its persuasiveness, provenance irrelevant)? — and reaches for the matching skill.
Before the full worked illustrations, it helps to see the two skills applied to the same historical issue, so the contrast is unmistakable. Take a debated question — say, why a particular government fell. Under AO2, you might be handed a minister's private letter written weeks before the fall, and asked how useful it is for investigating the causes: you would weigh who wrote it, when, and why (a private letter, not for publication, so likely candid), treat its anxieties as evidence of the pressures the government faced, and judge its value for the enquiry — high for the government's internal mood, limited for the wider forces at work. The letter is a fragment of the crisis itself. Under AO3, you might instead be given a modern historian's extract arguing that the government fell because of its leaders' avoidable decisions, and asked how convincing that argument is: you would set aside who the historian is, identify their criterion (failure explained by choice rather than by circumstance), test it against evidence that supports it (specific bad decisions) and evidence that qualifies it (structural constraints the leaders could not escape), and reach a judgement on the argument's persuasiveness. The extract is a reading of the crisis, not a piece of it. Same issue; two utterly different tasks. The rest of the lesson equips you to perform each.
The UG1 source enquiry presents contemporary sources and asks, in effect, how far they support a stated view, or how useful they are for investigating a specified question. The reward is not for summarising the sources, nor for displaying background knowledge for its own sake, but for evaluating the sources' value for that enquiry. Everything turns on the enquiry: value is not an absolute property of a source but a relation between the source and the question asked of it. The same source may be invaluable for one enquiry and nearly useless for another; the skill is to judge its worth for the enquiry given, and a strong answer keeps the enquiry in view in every sentence.
A disciplined evaluation weighs each source along four dimensions. None is sufficient alone; the strongest answers integrate all four and relate them to the enquiry.
| Dimension | The question it asks | Why it matters for value |
|---|---|---|
| Provenance | Who produced it, when, where, and in what position? | Locates the author's vantage point and access — what they were placed to know |
| Tone and emphasis | What does the language reveal — what is stressed, what omitted? | The slant is itself evidence; what a source emphasises reveals purpose and perspective |
| Purpose | Why was it produced — to record, persuade, justify, conceal? | Purpose shapes selection and reliability; a source made to persuade is strong evidence of what its author wanted believed |
| Content in context | What does it claim, and how does that sit against what you know? | Your own knowledge tests the content — corroborating, qualifying, or contradicting it |
The decisive reframing most students need is around bias. A biased or partial source is not thereby worthless; its very partiality is often its greatest value, because it is excellent evidence of a viewpoint, a mood, or a purpose. A hostile pamphlet is poor evidence of the facts it distorts but superb evidence of the strength of the hostility — and if the enquiry is about opinion or propaganda, the bias is the point. The top-band move is to treat bias as evidence to be interpreted rather than a defect to be deducted, always asking: what is this source, precisely because of its slant, good evidence of?
The fourth dimension, content in context, is where your own knowledge does its indispensable work, and it is the dimension weaker answers most often omit. Every claim a source makes can be set against what you independently know of the period — and it is that setting-against that turns reading into evaluation. If a source's account is corroborated by what you know, its value for the enquiry rises; if its account strains against the established evidence, that tension is itself informative, prompting the question of why the source departs from what is known. Knowledge deployed this way is not background decoration but the test that calibrates the source's worth: bring specific, relevant knowledge to bear at the exact point where the source makes a checkable claim, rather than appending a paragraph of context for its own sake, which earns nothing.
For each source a strong answer pairs value with limitation — never asserting usefulness without stating what the source cannot show, never dismissing a source without identifying what it nonetheless illuminates. And, where several sources are given, it reads them relationally, asking whether they corroborate, contradict, or illuminate different dimensions of the enquiry, and concludes on their combined value for the enquiry.
The following models the source skill. The source is paraphrased for teaching, not quoted. Imagine an enquiry into the reliability of official reports of prosperity in a state that tightly controlled its press, and a single source: an official regional newspaper article, published in that state, reporting record harvests and contented, well-fed villages.
Source (paraphrased for teaching). An official regional newspaper article reports that the year's harvest has been the finest in memory; that the granaries are full and the villages content; that the people are grateful to the government whose wise policies have delivered this abundance; and that only enemies of the state would spread rumours of hardship.
Specimen question modelled on the OCR H505 UG1 source enquiry (AO2): How useful is this source for an enquiry into whether the official reports of prosperity were reliable?
Mid-band response: This source is useful because it tells us that the harvest was very good and the villages were content and well-fed. It shows that the government said the country was prosperous. However, the source might not be reliable because it is an official newspaper and the government controlled the press, so they would want to make things look good and might not tell the truth about any hardship. So the source is useful for showing what the government claimed, but it might be biased and exaggerate the prosperity, so we cannot fully trust it.
Examiner-style commentary: This response makes a start on provenance (an official newspaper in a controlled press) and grasps that the source may exaggerate (M1), but it treats the source's unreliability as a simple weakness ("we cannot fully trust it") rather than asking what the source is good evidence of, given this specific enquiry. To reach the next band it must see that, for an enquiry into whether the official reports were reliable, the source's very propagandising is the point: a source that suppresses all hardship and attributes abundance to the government is prime evidence of how the official reports worked — and that the article's own swipe at "enemies of the state" spreading "rumours of hardship" inadvertently reveals that contrary reports existed.
Stronger response: For an enquiry into whether official reports of prosperity were reliable, this source is highly useful — not as a record of the actual harvest, which it almost certainly distorts, but as direct evidence of how the official reports operated. Its provenance is decisive: an official newspaper in a state that controlled the press had the purpose of persuading, not of recording, so its glowing account of full granaries and grateful villages is best read as propaganda rather than reportage. That does not diminish its value for this enquiry; on the contrary, it is exactly what the enquiry is about. The tone is revealing: the attribution of abundance to the government's "wise policies" shows the reports were designed to credit the regime, and the warning that "only enemies of the state" would speak of hardship is doubly telling — it shows the reports worked partly by intimidation, and it inadvertently admits that reports of hardship existed and had to be suppressed. Set against what is known of such controlled-press systems, the source corroborates that official prosperity-reporting was systematically unreliable as a record of conditions but highly reliable as an instrument of the state. Its limitation is that, alone, it cannot tell us what conditions actually were — for that a historian would need independent sources.
Examiner-style commentary: This is a genuinely evaluative answer: it works from the enquiry, uses provenance and purpose to reframe the source as propaganda that is valuable precisely because it is propaganda, and — the key advance — reads the "enemies of the state" line as inadvertent evidence that suppressed contrary reports existed (M1, M1, M1). To reach the top band it should press the content in context dimension harder — bringing specific knowledge of what independent evidence suggests actual conditions were, so as to measure the gap between the source's claims and reality — and sharpen the judgement on exactly what the source can and cannot establish for the enquiry.
