Ensuring Fairness
3
Principles of Fair Analysis : 1.Use an Appropriate Baseline 2.Compare ‘Like’ with ‘Like’ 3.Reflect Statistical Uncertainty

The Assessments MidYIS - Year 7, 8 or 9 Developed ability assessments: Vocabulary Maths Non-verbal (Cross-sections, Block Counting and Pictures) Skills (Proof Reading and Perceptual Speed & Accuracy) SOSCA (“INSIGHT Core”) – Year 9 Curriculum-based assessments: Reading (Passage Comprehension, Text Comprehension and Speed Reading) Maths (Number & Algebra, Handling Data and Space, Shapes & Measures) Science (Biology, Chemistry and Physics) INSIGHT – Year 8* or 9 ( * depending on numbers) Developed ability assessments (‘MidYIS’) plus Curriculum-based assessments (‘SOSCA’) Yellis - Year 10 or 11 Developed ability assessments: Vocabulary Maths Patterns (Matching and Reflections & Rotations) 3 sessions - Computer adaptive 4 sessions - Computer adaptive 1 session – Computer adaptive or paper-based 1 session - Computer adaptive or paper-based

Computer AdaptivePaper-based Number of Students per Test Session Limited by number of computers available – multiple testing sessions Can test all students in a single session (in hall or in form groups) or in more than the one session Cost Roughly 30% cheaper than paper-based test Standard cost Processing of Baseline Feedback Baseline feedback available within a couple of hours of testing Takes around 2-4 weeks for papers to be marked Preparation Must be able to install the software or access the internet version of the test No pre-test set up Student Experience “Tailored” assessmentAll students see all questions, irrespective of suitability Computer-adaptive vs Paper-based testing

Value Added Feedback
24
Burning Question : What is my Value-Added Score ? Better Question : Is it Important ? Principle of Fair Analysis No3 : Reflect Statistical Uncertainty
25
The Scatter Plot Baseline Score Grade Points Equivalent Look for Patterns… General under- or over-achievement ? Do any groups of students stand out ? – high ability vs low ability ? – male vs female ?
