Running your school on data
CEM data includes:
•
•
•
•
•
•
•
School profile bands
Baseline test acquired ability data, inc. IPRs
Predictive data inc. chances graphs
Value-added data
Attitudinal data
Curriculum assessments (Insight)
Software programmes (PARIS) with databases
So much data................................!
Some key questions:
1.
What data is needed?
(What data is not needed?)
2. And for Whom is the data ?
3.
What does the data mean?
(What does the data not mean?)
1. What data do I need? A key first step!
e.g. using MidYIS GCSE predictive data for target
setting
•
•
•
•
•
Point and/or grade predictions? (e.g. 5.8/grade B)
Based on whole cohort?
Based on the 75th percentile?
Based on prior value-added?
The chances graphs?

Discussion: setting the targets...........
• From your perspective, assess the merit of each type of
predictive data and the associated chances graphs
• Which type of predictive data would you use to set the
targets, and why?
• Would your students be involved as part of the target
setting process?
• Would parents be informed about the process and
outcome?
• How would you ensure that HoDs were involved to
ensure overview the process?
2. CEM data: who is it for? For example:
• SMT/SLT: summary data, attitudinal
• HoDs: Subject VAD, predictive data
• Subject teachers:
• FormTutors:
• Head of Learning/Year/House:
• Parents:
• Pupils:
and not forgetting:
• Governors:
• Media:
3. What does the data mean?
e.g. value-added data:
• The difference between raw and standardised
residuals
• The use of confidence limits to distinguish between
average and statistically significant data, and to allow
for small entry subjects
• Can ‘zero’ or even ‘negative value-added’ be
acceptable?

Case study: Alis value-added data
Four sets of VAD are available!
From average GCSE baseline:
• all Alis cohort
• type of Institution
• Syllabus
From the baseline test
• all Alis cohort
SPC Chart with confidence limits: WHOLE SCHOOL
All Alis Cohort:

Institution
Using PARIS software: Baseline Test
Whole School
From your perspective, which set of VAD would you use for the
different user groups? (Governors, HoDs, Media, Parents, SMT/SLT...)

USE ONE YEARS DATA WITH CAUTION!
•
Better to use three years data as patterns over time are
more significant.
CEM data is used for:
•
•
•
•
•
•
Teachers to help learners
Curriculum and staffing decisions
Target setting and monitoring pupil progress
Inspection evidence
Self-evaluation
Monitoring changes over time such as pupil
ability intake profiles and VAD
• Asking the question ‘can we do better?’
i.e. the data is used to aid and to support
professional judgement
with due consideration to:
•
•
•
•
Ethos and tradition of ‘my’ institution
Accountability
Parental expectations
Staff training in use of, and ability to cope
with, data (data overload)
• Management of data: integrating the data
into school procedures, storage, retrieval,
distribution and access……policy?
