Technical notes
SATs scaled scores:
Scaled scores range from 80 (lowest)
to 120 (highest). The national expected
standard is 100 scaled scores. This
makes results comparable year on year
to account for variation in assessment
di昀케culty. The single reading paper has
a maximum of 50 raw marks that can
be achieved and the 3 maths papers
have a maximum of 110 marks that
can be achieved.
SATs % of questions correct:
This method was used for illustrative
purposes and provides an approximate
demonstration of progress. Pupil progress
was measured using the 2024/25 Key
Stage 2 scaled score conversion charts.
Average mock scaled scores for reading
and maths were converted into raw
marks using these charts and were
recorded as a percentage. Progress was
then calculated as the average increase
in scaled scores. To estimate the increase
in questions answered correctly, the
average scaled-score increase was
applied to the conversion chart by
counting upward through the scaled
score ranges. The raw mark associated
with this adjusted scaled score was
taken from the chart and expressed
as a percentage. This allowed progress
to be shown as a change in percentage
of total questions answered correctly
across reading and maths papers.
Government Benchmarking –
SATs (Disadvantaged Pupils):
Provisional data from the DfE was used as
a benchmark to compare attainment (KS2
Explore Education Statistics, 11/09/2025).
Attainment for disadvantaged pupils
was analysed separately for reading
and maths across local authorities
where we delivered those subjects in
2024/25. The benchmark percentage was
calculated separately for each subject as:
(Disadvantaged pupils meeting expected
standard ÷ Total eligible disadvantaged
pupils) across relevant local authorities.
‘Disadvantaged’ follows DfE criteria
(FSM6, looked after, or previously looked
after). Tutor Trust pupils were categorised
as disadvantaged if receiving Pupil
Premium and/or cared for.
Government Benchmarking –
SATs (SEND Pupils):
The same approach was applied
using the DfE ‘All SEN provision’ 昀椀lter
instead of ‘disadvantaged’ (data
released 11/09/2025).
Government Benchmarking –
GCSE (Disadvantaged Pupils):
Provisional data from the DfE was used as
a benchmark to compare attainment (KS4
Explore Education Statistics, 16/10/2025).
Attainment for disadvantaged pupils was
analysed separately for English, maths,
and science across local authorities
where we delivered those subjects in
2024/25. The benchmark was calculated
as: (Disadvantaged pupils achieving
grade 4+ in [EBacc subject] ÷ Total
disadvantaged pupils at end of KS4).
For science: (Disadvantaged pupils
achieving grade 4+ in EBacc [science]
÷ Disadvantaged pupils entered for
EBacc [science]). Tutor Trust pupils were
categorised as disadvantaged if receiving
Pupil Premium and/or cared for.
Government Benchmarking –
GCSE (Disadvantaged Pupils
with SEND):
National benchmark data for 2023/24
was provided by the DfE via a Freedom
of Information Request; local authority
breakdowns were unavailable.
Post-16 benchmarking data:
As full 2024/25 data is not yet published
for all retake age groups, we have
benchmarked against 2024/25 data
for 17–19 year olds. GCSE results 2025:
