Relating your PIRA and PUMA test marks
to the national standard
We have carried out a detailed statistical analysis between the results from the PIRA and PUMA tests for Year 2
and Year 6 and the scaled scores of the 2016 national tests.
In doing this, the PIRA and PUMA test raw scores of 1,150 children for PiRA and over 1,400 children for PUMA
from 56 schools across the country have been linked to the scaled scores achieved by the same children in their
actual national tests*.
In order to describe the relationship between the Rising Stars PIRA and PUMA tests and the national test
scores, a statistical technique known as linear regression was used to model the relationship between the two
variables. Outputs of this analysis are provided below as tables and graphs to assist teachers in using the
findings to relate their own children’s PiRA and PUMA marks to the national test scaled scores.
*Please note that this will be indicative only. Other factors can influence a child’s performance on any given day.
How this analysis will help you
The results of this analysis provide teachers with a clear indication of the marks children are likely to need in
their PIRA and PUMA tests in order to achieve a scaled score of 100 or above when they sit their national tests.
The Relationship Tables show what PIRA and PUMA raw marks were achieved by children who went on to
achieve 100 or more in the national tests. Children achieving similar scores in the PIRA and PUMA tests in 2016-
2017 would therefore be operating at the national standard. The analysis correlates all PIRA and PUMA marks
to the full range of scaled scores from 85 to 115 at KS1 and 80 to 120 at KS2. This analysis should concentrate
efforts to help identify those currently on track to perform slightly below the 100 scaled score, so you can use
your PIRA and PUMA gap analysis to highlight the areas for development/intervention.
Relating your PIRA and PUMA test marks
to the national standard
Using the Relationship Tables
The Relationship Tables have been created to enable you to monitor the marks children are likely to
need in their PIRA and PUMA tests in order to achieve a scaled score of 100 or above when they sit
their national tests
The middle column shows you the child’s Estimated Scaled Score. The numbers on either side of this
are prediction and confidence intervals – this simply means they show the lowest score the child is
likely to achieve, and the highest. Because all children and all test experiences vary, it is impossible to
say that they will definitely achieve the number in the middle column – but you can be comfortable
that there is a 95% chance they will achieve a score between the lowest and highest listed in that row.
Using the Relationship Graphs
For each table there is a corresponding graph which has the PIRA or PUMA test marks plotted against
the national test scores, for easy reference. Either side of the central line are two lines directly above
and below which show the upper and lower 95% confidence limits for the estimated scaled score of
all pupils in the population.
The outer lines show a prediction with 95% confidence for individual pupil’s scaled score from their
PIRA or PUMA test mark.
