How to Write a Marking Scheme (Rubric): 2, 3 and 5-Mark Examples

A marking scheme is the reason copy 1 and copy 200 get the same marks for the same answer, and the reason two teachers checking one paper agree. Without one, the standard lives in the checker’s head, and heads get tired.

This guide shows how to write one for subjective questions, with three worked examples: a 2-mark definition, a 3-mark “explain the factors” question and a 5-mark long answer. The examples use Class 10 Geography content so that they are familiar, but the method works for any subject.

What a marking scheme is (and what it is not)

A marking scheme, or rubric, lists for each question the points that earn marks, how much each is worth, and how to treat answers that are half right. A good one also has a model answer for reference and a short note on what does not earn marks.

Indian board schemes are a useful model. CBSE’s published marking schemes list “expected answers / value points” for each question with the marks per point, written like “½ × 4 = 2”, and often add “Any other” so that other correct points are credited. The general instructions to examiners go further: the value points are guidelines and not the complete answer, and if a student’s own expression is correct, the due marks should be awarded.

That is the spirit to copy. A marking scheme describes what a good answer contains. It is not a script the student must reproduce.

There are two broad styles:

• Point-based (value points): marks for each correct idea. Best for definitions, “explain the factors” questions, numericals and most short and long answers in content subjects.
• Level-based (bands): a description of what an answer looks like at each level. Best for essays, letters and arguments, where quality matters more than a count of points.

This guide focuses on point-based schemes, with a note on levels for long answers.

Six rules for criteria that work

1. 1

   Make the criteria add up exactly to the marks

   A 3-mark question has criteria worth 3, not 2½ or 4. If you allow “any three of five points”, say so, and say that each point can earn marks only once.

2. 2

   One idea per criterion, written as something you can see

   “Names a factor and says how it helps form soil” can be checked. “Shows good understanding” cannot, and two teachers will read it two ways.

3. 3

   Decide half marks in advance

   Write down exactly what earns ½: a factor named but not explained, a definition with one of its two parts, the right method with an arithmetic slip.

4. 4

   Keep the marks out of the criterion text

   Put marks in their own column. A figure buried in the wording, such as “explains the effect (2 marks)”, goes stale the moment you edit or rescale the criteria, and then the text and the marks column disagree.

5. 5

   Treat the model answer as a reference, not required wording

   Students who say the right thing in their own words earn the marks. List the common acceptable alternatives so checkers do not have to decide on the spot.

6. 6

   Say what does not earn marks

   Write down the near-misses you expect: the related but wrong term, an effect given in place of a cause, a list of examples in place of a definition. It saves a decision on every copy.

Two more conventions from CBSE’s instructions to examiners are worth borrowing. Penalise an error only once, not again in every later step that depends on it. And use the full range of marks: give full marks when an answer deserves them.

Example 1: a 2-mark definition

Question: What is a resource? (2 marks)

Model answer (for reference): Everything available in our environment that can be used to satisfy our needs, provided it is technologically accessible, economically feasible and culturally acceptable, is a resource.

Accept: “can be used by people” or “useful to us” for “satisfy our needs”; “we have the technology to use it” for technologically accessible; “affordable to use” for economically feasible; “accepted by society” for culturally acceptable. Do not accept: a list of examples (water, coal, soil) in place of a definition. Examples show that the student recognises resources, not that they can define one.

Notice what the scheme does not do: it does not demand the textbook sentence. A student who writes “Anything around us that people can use to meet their needs, if we have the technology, it is affordable and society accepts it” earns both marks.

Example 2: a 3-mark “explain the factors” question

Question: Explain any three factors that help in the formation of soil. (3 marks)

Factors to accept: relief, parent rock (bed rock), climate, vegetation and other forms of life, and time.

Explanations to accept include, for example:

• Climate: changes in temperature, and the action of running water, wind and glaciers, break rock down into smaller particles.
• Vegetation and other forms of life: decomposers break down dead plants and animals and add organic matter to the soil.
• Time: soil forms very slowly; it takes millions of years for soil to form even a few centimetres deep.
• Parent rock: soil is formed from the rock that is broken down, so the rock shapes what the soil is made of.

Why split each factor into naming and explaining? It rewards the student who knows the factors but explains them weakly, without giving full credit for a bare list. It mirrors the “½ × 6 = 3” pattern you will find in CBSE marking schemes.

Example 3: a 5-mark long answer

Question: What is soil erosion? Explain two causes of soil erosion and two methods of soil conservation. (5 marks)

Model answer (for reference): Soil erosion is the removal of the soil cover and its washing down. One cause is deforestation: once trees are cut, there are no roots to hold the soil, and rain washes it away. Another is defective farming, such as ploughing up and down a slope, which makes channels for water to run down quickly and carry the soil with it. One method of conservation is contour ploughing: ploughing along the contour lines slows the flow of water down a slope. Another is planting shelter belts, rows of trees that break the force of the wind. In western India, shelter belts have helped to stabilise sand dunes.

Accept as causes: deforestation, overgrazing, construction and mining, defective farming such as ploughing up and down the slope, and natural forces such as wind, glaciers and running water. Accept as methods: contour ploughing, terrace farming, strip cropping and shelter belts. An Indian example, such as terrace farming in the western and central Himalayas, is welcome but is not required for full marks.

Keep the criteria independent. A weak definition costs the definition mark only. It should not pull down the marks for causes and methods that are explained correctly.

When a level-based scheme fits better

If the same 5 marks were for a piece of extended writing, such as “Should farmers on hill slopes switch to terrace farming? Give your view”, counting points would reward listing over reasoning. A level-based scheme fits better:

Even with levels, keep the descriptions observable, and decide in advance what moves an answer from the bottom of a band to the top.

And for numericals: method marks

The same rules apply to a numerical, with one addition: give marks for the method, not only the final answer. For “A car travels 150 km in 3 hours. Find its average speed. (3 marks)”, a workable scheme is:

A student who writes 150 ÷ 3 = 60 keeps the formula and substitution marks and loses only the answer mark. If a wrong value from one step is then used correctly in the next, penalise the error once, where it happened, and credit the later steps that follow from it correctly.

Common mistakes

• Criteria that do not add up. Criteria worth 4 for a 3-mark question, or a scheme in which full marks are impossible.
• Vague words. “Proper explanation”, “good answer”, “relevant points”. Replace them with what you will actually see on the page.
• Double counting. The same idea earning marks under two criteria, such as an example that also counts as the explanation.
• Marks hidden in the text. A “maximum 1 mark for examples” buried in a description, which quietly conflicts with the marks column after someone edits it.
• Textbook wording as a requirement. It penalises students who understand the idea but put it in their own words.
• No rule for choices and extra answers. If a student attempts both options of an “OR” question, the scheme should say which answer counts. CBSE’s instruction is to keep the answer that deserves more marks and score out the other with a note, “Extra Question”.
• Writing the scheme after marking has started. The first copies get one standard and the rest get another.

Test the scheme before you mark

Before marking the whole stack, mark five varied copies with the scheme. Any answer you hesitate over is a gap: add it as an accepted alternative or a near-miss. If two teachers share the paper, both mark the same five and compare. Where you disagree by more than half a mark, the wording of a criterion is usually the cause. Then freeze the scheme and mark the rest.
