Evaluation and Appraisal

Additional information about what the test measures Mathematical skill and knowledge, process skills of fluency, mathematical reasoning and problem-solving.Scores can be differentiated by curriculum content area (number; algebra; Ration, proportion and rates of change; Geometry and measures; Probability; Statistics) or by process category (Fluency in facts and procedures; Fluency in conceptual understanding; Problem solving; Mathematical reasoning)
Are additional versions available? Paper and digital versions are available.Consists of 10 yearly tests to cover the age range 5 to 14+ (Progress Test in Maths 5 to 14), plus an additional test for pupils aged between 11 and 12 years, which can be used as a transition test on entry to secondary education (Progress Test in Maths 11T)
Can subtests be administered in isolation? No but strand scores can be differentiated
Administration group size small group, whole class
Administration duration Not timed tests, examinees should be given as long as needed.Levels 5-7 should take 45-60 minutes.Other levels should take no more than 60-75 minutes.Tests can be administered in 2 parts.

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) The Technical Information and Links to National Curriculum documents indicate that there is good face validity - a good deal of descriptive explanation is provided about test development, including detailed explanation of how the tests align to national curriculum. There was substantial trialling of items and analysis of discriminant validity between high and low performers at the item level before selecting items for the final version and re-standardising. However, these analyses are not presented for evaluation.The only measure of construct validity reported correlates performance on the PTM with PiM (a previous version of the test), this shows good correlations (r .62-.88) but is not an independent measure of validity.

Criterion Validity

Does test performance adequately correlate with later, current or past performance?
Summarise available comparisons n/a

Reliability

Is test performance reliable?
Summarise available comparisons Excellent internal consistencyis reported in the Technical Information, however little information about the sample, Cronbach's alpha >.9 except for PTM5 (.87-.95, see p3 of technical information for test specific reliabilities); SEM 3.3-5.4 (see p3 of technical information for test specific reliabilities); 90% SAS band 5-9 (see p3 of technical information for test specific reliabilities)

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. Standardisation does not differentiate between digital and paper version.Standardisation samples are independent from trial samples. Separate standardisations conducted for United Kingdom and for Northern Ireland.Standardisation of paper version took place between February and May 2014 for PTM5-11 and September-October 2014 for PTM11T.Sampling was stratified at school level, by country, independent/grammar school, school performance based on Key Stage 2/GCSE outcomes. However, little information provided about the demographics of the population making it difficult to confirm lack of bias (although this isn't anticipated to be a problem due to sample size and school characteristics)"
