Baseline Assessment Data
• To inform professional
judgement
• To start a conversation
USING BASELINE DATA FOR TEACHING AND LEARNING
IF FEEDBACK DATA IS TO BE TRUSTED THEN PROBABLY:
•
The students understood the purpose of the
assessments
• And each student did their best at the time…….
• As a year group, how able are they?
• What strengths and weaknesses does the group have?
• How did each student perform?
Bands, percentiles, standardised scores…

BASELINE SCORE

3 key points are:
• The higher the baseline score the higher
the final grade
• Any one grade is achievable from a range
of baseline scores
• From any baseline score, a range of
grades are possible

‘Predictions’…...are based on
Average performance by similar
pupils in past examinations
The problem with the word ‘prediction’ is…?
An alternative is ‘expected’ grade

FACTORS THAT WILL INFLUENCE
RELIABILITY OF PREDICTIONS:
•
•
•
•
•
•
•
•
•
•
Knowledge of student
Parental support/home life
Peer influences/social life
Student attitude, interest, language
Expectations of staff
Department/institution ethos
Resources
Quality of teaching and learning: pace of lessons
Understanding how children learn………
And the reliability of the predictions......

Not a label for life
...just another piece of information
• The Chances graphs show that, from almost any
baseline score, students come up with almost any
grade - - -there are just different probabilities for
each grade depending on the baseline score.
• In working with students these graphs are more
useful than a single predicted or target grade
• Chances graphs show what can be achieved:
– By students of similar ability
– By students with lower baseline scores
