Grammatical Range and Accuracy at Writing Band 8

The band descriptors say that a band 8 in Grammatical Range and Accuracy is writing where:

  • there is a wide range of grammatical structures
  • The majority of the sentences are error-free.  


Some believe that majority is more than half but compare this statement with one from band 7 which says, “produces frequent error-free sentences.”  Sentences at band 8 must be more correct than just frequently; assume that most of them must be correct.  

Remember that at band 8 the examiner may be slightly more lenient with errors in complex grammar, but simple grammar should be accurate.  

Areas where students often make errors include:

  • Articles (a, an, the, zero article)
  • Prepositions
  • Subject-verb agreement
  • Overusing present continuous


Here, you must show a great variety of structures, ideally complex grammar.

Some advanced grammatical structures that students often use include:

  • Modal verbs (can, could, would, must)
  • Passive voice 
  • Relative clauses

Band 8 requires using more than just the above, however.   Some examples of advanced grammatical structures follow.

Conditional sentences (If…then)

Most students are familiar with these sentences yet avoid them because of the combination of tenses required.  

If governments implemented and enforced measures, pollution could be reduced.

Band 8 students use more advanced forms of conditional sentences, including those without if.

Were governments to implement and enforce measures, pollution could be reduced.

It is also possible to use if + adjective rather than an entire clause.

If possible, governments should create public service campaigns regarding reducing fossil fuels.  (=if it is possible) 

If necessary, strict fines should be given to factories that do not reduce their emissions. (=if it is necessary).

Relative clauses

Most students are familiar with using which and that in their writing but rarely attempt higher level usage of relative clauses.   These include:

  • Relatives with expressions of quantity
  • Relatives with prepositions or connectors.


There are numerous measures that can be taken to reduce air pollution, many of which require governmental intervention.  

Researchers have discovered that microplastics, many of whose effects are still unknown, have been found in sea creatures that are later eaten. 

The number of full-time students fell to 80,000 in 1985, after which the figure remained stable until the end of the period. 


Inversion is an example of a high-level grammatical structure that few students attempt.  There are several different ways to create inversion.   In all of them, the verb and subject are inverted as in question order.

Rarely/ barely/ hardly/ never/ not only (at the beginning of a sentence)

Not only should citizens use their cars less, but they need to use less electricity in their homes also.

(=Citizens should use their cars less and they should also use less electricity in their homes)

Never has it been so important to adopt measures to protect the environment. 

(=It has never been so important to adopt measures to protect the environment) 

Inversion is also created with only + then/ later/ / by/ after, and not until when they begin a sentence or subordinate clause but here the inversion comes in the main clause.  

Not until governments step up their efforts to reduce pollution will we see light at the end of the tunnel.  

(=We won’t see light at the end of the tunnel until governments step up their efforts)

Only by looking at the matter in further detail can we understand its complexity.  

(=We can under the matter’s complexity only by looking at it in further detail)

Participle clauses

These can use the active participle (-ing) or passive participle (-ed) to provide extra information, describe the cause of the information in the main clause or even the reason for it.  

More people are moving to cities, causing more emissions from vehicles to be released into the atmosphere.

 (=which causes)

Fully implemented, these measures could reduce the effects of pollution in our urban centers.

(=if they are fully implemented)

Having seen the effects of climate change, the scientific community has sounded the alarm on fossil fuel emissions.  

(=Because they have seen)

Cleft sentences

These are sentences that begin with It is/ was, followed by an emphasized word + a relative pronoun.   Cleft sentences are used to emphasize a particular word or phrase.  

It is companies which have the responsibility of curbing fossil fuel emissions most.  

(= Companies have the responsibility of curbing fossil fuel emissions most)

Another type of cleft sentence can be created with a what clause + be + verb/ noun.

What governments need to do is implement measures penalizing companies that create emissions.

(=Governments need to implement measures penalizing companies that create emissions)

Cleft sentences are also common in spoken English, so practice using these for your speaking test as well.  

Remember that at Band 8, test takers are expected to show proficient use of English.  Language should be natural but also show complexity and accuracy.  

Experiment with some of the above grammatical phenomena to extend the range of structures you use and make a positive impression on your examiner.
