Using CEM Data in Practice: Feedback from CEM Secondary Assessments Peter Hendry: CEM Consultant Using CEM Data in Practice: Feedback from CEM Secondary Assessments Glasgow Conference 13th Feb 2013 Peter.Hendry@cem.dur.ac.uk Secondary@cem.dur.ac.uk
Assessment for Excellence: 2 systems S1/S2 Baseline Assessment (MidYIS): A Test of Developed Ability at start of S1 or S2 4 sections: Vocabulary, Maths, Non-Verbal and Skills (Proof Reading, and Perceptual speed and accuracy Computer adaptive* or paper-based Any time Term 1 + catch ups Value Added measures to SOSCA and to Scottish Qualifications S2 Curriculum-based Assessments (SOSCA): A curriculum assessment of knowledge, skills and understanding at end of S2 Assesses what has been taught in the classroom Covers, Maths, Science, Reading (English) Computer adaptive* Four week assessment window mid April to mid May + catch ups Value Added measures from PIPs, InCAS and MidYIS and to Scottish Qualifications Assessment for Excellence – 2 systems – MidYIS in S1 or S2 SOSCA at end S2 – this is the focus of this presentation Reading is a proxy for English – can’t manage the writing execise or the marking but reading is an excellent proxy for English and correlates very well with performance in English 2
AfE: key elements School and students’ test performances are compared to a nationally representative sample Assessment data from the tests provides school and pupil data to inform teaching and learning ‘Predictive’ data indicates future potential performance to SQ, and will to National 4 and 5, to inform target setting and subsequent monitoring ‘Value-added data’ provides measures of relative performance at SQ (and will for National 4 and 5) and SOSCA from earlier baselines to inform self-evaluation
AfE Feedback: MidYIS and SOSCA Assessment Feedback: Standardised score system: 50-150, mean 100, SD 15 School data including component averages and band profiles (historical and current) Pupil data in the form of spreadsheets and Individual Pupil Records (IPRs)
AfE Feedback: MidYIS and SOSCA ‘Predictions’ Feedback: Currently to S2 SOSCA from S1/S2 baseline (MidYIS) and to SQ from MidYIS and SOSCA ‘Value-Added’ Feedback: To SQ from curriculum baseline (SOSCA), and from S1/S2 baseline (MidYIS) To S2 curriculum assessment (SOSCA) from P7 baseline (PIPS or InCAS) and/or S1/S2 baseline (MidYIS)

Detailed Information about the assessment. Well worth a look. Data for your school.

Predictions Feedback Currently available to Standard Grade from AfE baselines In the future to National 4 & 5 Qualifications from AfE baselines Also to AfE S2 curriculum (SOSCA) from S1 and/or S2 baseline (MidYIS) Includes Chances Graphs
How is a ‘prediction’ generated? 50% on or above the trend line 1 Trend line (regression line) *********************** 2 ******************************* 3 ******************************************* ‘PREDICTION’ (expected grade) 4 GRADE ************************************* GRADE ************************************** ******************************** ***************************** 50% on or below the trend line ***************** BASELINE SCORE
Data for 2012 examinations Grade
Predictions: Chances Graphs 50% chance of a grade 2 – the most likely single grade. 50% chance of a different grade Point Prediction =1.8 Grade Prediction = 2 Chances Graphs based on Pupil’s SOSCA Test Score 25
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
Latest information as at 13 Feb 2102 Replacing SG with Nat 4 & 5 predictions: CEM statisticians have put together a proposal. This has been looked at by colleagues in Scottish Authorities. The CEM Technical team have now published the new predictive data. This data is now available on the CEM secondary+ website alongside the existing SG predictive data
