ALIS data
West Island School
October 2013
Mike Williams (Data Development Leader)
Advanced Level Information System Run by Centre for Evaluation and Monitoring
@ Durham University. 29 years worth of data. 1.3 Million Students in CEM system About 10K students per year doing IB,
mainly international schools and UK independent schools.
ALIS
Measure Student’s abilityIntake ProfilesIPR - Strengths and Weaknesses, provides valuable information to support teaching and learning of individual students.
Project future performance from national trendsChances Charts, target setting and subsequent monitoring.We do not use to predict future grades for University or IB predictors.
Compare actual performance to Projected Performance
Value-Added Reports. Used to assess performance of our school.
Basic Principles of ALIS Data
Assessed by a computer adaptive test that takes 1 hour Demo Test
Measures developed ability rather than taught curriculum
No preparation is required for the test
Components are vocabulary (words and phrases) maths (numeracy) non-verbal (spatial/3d)
School and students’ test performances are compared to students around the word.

Look at each example and discuss the potential impact on learning and teaching.
What could a student do to improve their ability in areas which are relatively low?
Do these scores have an impact on any future pathway decisions?
Example IPRs
Sample Chances Charts• The following charts show the percentage of students,
who achieved the same baseline score as your children, went on to score a particular grade at IB.
• It is not meant to predict what grade your children will achieve, but is an indication of how previous students of similar ability performed in that subject.
• Two baselines are used. (LHS) Average GCSE score, (RHS) ALIS (CABT) test score.
• The black line shows the average score achieved by students of similar ability, this is shown as ‘predictions points’ in the table at the top
Note: GCSE grades are converted into numbers A*=8, A=7, B=6, etc.
These students may have underperformed at GCSE. We would try to ensure that they are ‘on task’ from the start of their IB course.
Tracking: Using CABT and GCSE based predictors to highlight IB students who may
have underperformed at GCSE
This is a current year 12 IB class
Tutors and year teams can use charts to track progress at each reporting point.
This student would be tracked and supported by the tutor and upper-school team as she may be underperforming and she is in danger of not achieving the IB Diploma.
This chart shows the progress of students in a tutor group compared with their average predicted grade.
