Evaluation and Appraisal

Additional information about what the test measures Maths (number, calculations, fractions, decimals and percentages, ratio and proportion, algebra, measurement, geometry and statistics)
Are additional versions available? There are different test papers for each term between year 1 and year 6 - so 18 papers.
Can subtests be administered in isolation? n/a
Administration group size small group, whole class
Administration duration varies depending year group and term, but approx 40 mins for autumn and spring tests for KS1, 85 mins for KS2, 50 mins for summer tests KS1 and 120 for KS2.
Description of materials needed to administer test pencil or paper, answer booklets, rules, erasers and a protractor for KS2
Any special testing conditions? the tests are ideally presented in mid November, mid March and mid June. The autumn and spring tests are shorter, while the summer test mimics a full SATs paper, but based on content for that year group.

Response format

Response mode Paper and pencil
Queston format. mixed
Progress through questions Flat

Assessor requirements

Is any prior knowledge/training/profession accreditation required for administration? no
Is administration scripted? No


Description of materials needed to score test scoring can be done using the test guidance manual or online
Types and range of available scores age standardised score (70-130), standardised score (70-128), scales score correlations, performance indicators, mathematics age equivalent score (4;4-12;7), NTS scale
Score transformation for standard score age standardised - in comparison to others the same age in that year group; standardised - in comparison to others in that year group.
Age bands used for norming 1 month
Scoring procedures simple manual scoring - clerical skills required
Automatised norming bureau service

Construct Validity

Does it adequately measure literacy, mathematics or science?
Does it reflect the multidimensionality of the subject? Generic Maths
Construct validity comments (and reference for source) Face validity is high - the mapping from national curriculum content is very detailed and clear in the Mathematics Key Stages 1 and 2 Test Guidance. The tests are developed to closely mimic the SATs tests. However, construct validity is not measured statistically.

Criterion Validity

Does test performance adequately correlate with later, current or past performance?
Summarise available comparisons The publishers have calculated the prediction from scores on the test to SATs scores in the same school year and use this to provide predicted SATs scores. However the Mathematics Key Stages 1 and 2 Test Guidance does not detail how closely the two factors correlate.


Is test performance reliable?
Summarise available comparisons Internal consistency is good-excellent. Cronbachs alpha and SEM is reported for each test paper (p81 of the test guidance). Values range between .82 and .96, with most values above .9 . SEM is also reported for each test paper, and ranges from 2.08 to 4.67. The tests therefore show good reliability. Temporal stability and equivalence reliability are not presented.

Is the norm-derived population appropriate and free from bias?

Is population appropriate and free from bias? Yes
If any biases are noted in sampling, these will be indicated here. Large representative sample. Good range of information to confirm that the schools used were varied and representative of English schools as a whole. Overall measures of disadvantage and attainment for the schools reflected English averages
