Overview

At the end of key stage 1 (KS1), pupils take national curriculum tests in mathematics and English reading. They may also take an optional English grammar, punctuation and spelling test. We use scaled scores to report the outcomes of these tests to ensure we can make accurate comparisons of pupil performance over time.

Teachers will take a pupils performance in the tests into account when making their teacher assessment judgements. These judgements are used to report on the progress of pupils at the end of the key stage.

Scaled score conversion tables

You should use the conversion tables to convert raw scores to scaled scores.

What is a scaled score?

Tests are developed to the same specification each year, however, because the questions must be different, the difficulty of tests may vary slightly each year. This means we need to convert the total number of marks a pupil gets in a test (their raw score) into a scaled score to ensure we can make accurate comparisons of pupil performance over time.

Pupils scoring at least 100 will always have met the expected standard on the test. However, given that the difficulty of the tests may vary each year, the number of raw score marks needed to achieve a scaled score of 100 may also change. For example, if the overall difficulty of a test decreases compared with previous years, the raw score required to meet the expected standard will increase. Similarly, if the test is more difficult, the raw score required to meet the expected standard will decrease.

In 2016, panels of teachers set the raw score required to meet the expected standard. We have used data from trialling to maintain that standard for the tests from 2017 onwards.

Calculating raw scores

The KS1 tests are marked locally in schools to calculate the total number of marks a pupil receives. Each of the KS1 tests has 2 papers. You add the scores from both papers to calculate the raw score for the test in each subject.

Range of scaled scores and the expected standard

The range of scaled scores available for each test is the same as set in 2016 and is intended to stay the same in future years. The lowest scaled score that can be awarded on a KS1 test is 85. The highest scaled score is 115.

Pupils scoring at least 100 will have met the expected standard in the test.

A pupil awarded a score of 99 or less has not met the expected standard in the test.

Pupils need a minimum raw score before they can be awarded the lowest scaled score. Pupils who do not achieve the lowest scaled score on the test have not demonstrated sufficient understanding of the KS1 curriculum in the subject. You should award these pupils an N for the test. It is likely that these pupils should be teacher-assessed using the pre-key stage standards.

The conversion tables also show that sometimes 2 or more raw scores convert to the same scaled score. This is because data from pupils showed that the attainment of pupils who score these total marks is not very different.

There are also times when it is not possible to achieve a particular scaled score on this test. This is because of the limited number of questions in these tests, although these scores may be possible on previous or future tests.

Using and interpreting test outcomes

You should use evidence from the English reading and mathematics tests to inform your teacher assessment judgement for each pupil. You can also use the optional KS1 English grammar, punctuation and spelling test to inform your teacher assessment judgement in English writing.

The tests can provide evidence that a pupil has met certain pupil can statements, as well as evidence to support the judgement overall. Tests and teacher assessment are different forms of assessment, so it is not necessary for the outcomes to be the same.

The national curriculum tests are compensatory as pupils can score marks from any parts of the tests, pupils with the same total score may achieve their marks in different ways. The teacher assessment frameworks are different and ask teachers to assess pupils against certain aspects of the national curriculum, based on a range of evidence from the classroom.

It is possible for a pupil to have met the expected standard in the test, but not for teacher assessment, because of gaps in their knowledge or understanding. It is also possible for pupils to have demonstrated their attainment of the pupil can statements through their classwork, but not to have achieved the mark for a related question on the test. If a pupil gets a question wrong in the test on an area of the curriculum that they have demonstrated in their classwork, the teacher will want to take this into consideration when making their teacher assessment judgement.

Together, the tests and teacher assessment provide a broader picture of pupil attainment.
