  2. What and Why Stat Mod and Study Score • A process that Moderates the School-assessed Coursework scores • Uses the exam scores because it is the only task that is exactly the same for each student in the study

  11. Partnerships andStatistical Moderation Stat Mod and Study Score • Statistical Moderation works most effectively with groups larger than 5 • The VCAA requires that schools form partnerships • Schools who find it difficult to find a partner for any reason; lack of time / lack of access / lack of willingness can be reassured that the statistical moderation process is run as usual with the addition of precautionary checks

  12. VET andStatistical Moderation Stat Mod and Study Score • The moderation group for VCE VET coursework scores is the RTO that has delivered the program for a group of students. • The group may be all the schools auspiced by the RTO

  17. Important Points toRemember about Stat Mod Required so that school assessment can be used fairly as part of VCE assessment Any adjustment to a students’ coursework scores is made solely on the basis of the relationship between the groups coursework scores and external scores for the group. Does not change the rank order of students as determined by the school Not influenced by students with negative anomalous results as they are excluded from the moderation process before moderation formulas are calculated Students whose scores are excluded have their scores moderated using the formulas calculated for the rest of the group Stat Mod and Study Score

  18. Study Score Calculation Stat Mod and Study Score • To be eligible for a study score a student must achieve ‘S’ results for units 3&4 in the one year, unless granted Interrupted Studies status. • Achieve two or more GA results in the study • A study score is calculated using the students’ final numeric score in each GA with each GA contributing a specified percentage • Number between 0-50 with mean 30 and standard deviation 7 • Study scores are distributed according to the properties of a normal distribution curve

  23. Things to Remember Stat Mod and Study Score • Indicates how the student performed against all other students who did the study in that year. • Calculated using the numeric results for the GA not the grade. • Moderated coursework scores are used when calculating study scores to ensure fairness. • A strong performance on one GA and a weak performance in another GA will not necessarily result in a high study score • Studies where there are less than 250 students are reviewed each year by the Study Score Review Panel, consisting of Executive members of the VCAA and VTAC and adjustments made based on the available data from the previous five years.

  24. What is Used in theCalculation of a DES • School assessment is the primary data • In addition, other data is used where appropriate • If the student has the DES application approved, and the best predictor is better than the achieved score then the predictor becomes the student’s final score. • For all examinations, analysis indicates that the two other GA scores provide the greatest contribution to all the predictors.

  25. Indicative Grades • Indicative Grades: • primary purpose is to be used as part of the quality assurance procedures for marking examinations, however they are also used in the calculation of the DES. • are the prediction of a student’s actual level of achievement on the examination • the rank order and level of spread of the indicative grades for the school cohort in the study is of prime importance The published previous years grade range can be used to inform this process.
