Let me try to explain why 'Grade Inflation' is a totally unfair analysis of the situation, using another summer obsession: cricket 1/8 @teacherhead @johntomsett @RealGeoffBarton @mrjamesob
Try to predict England’s first innings score in the next test match. Imagine they have the same starting XI as the last match. Your prediction must be fair and balanced, using all of the available information on each player & be based upon them playing under normal conditions 2/8
Your prediction should be broadly in line with England’s first innings scores, in England, over the last three years 3/8
What will each player score? You examine the data and agree that it is fair to start by looking at each player’s test batting average. If every player scores exactly their average then England’s first innings score should be 328.78. Let’s round that up to 329 all out 4/8
However, England’s first innings scores in tests, in England, since 2017, average out at 289.71. Let’s call that 290. Oh dear! By giving each player a fair and balanced assessment, are we guilty of grade inflation? 5/8
So, to bring it down in line with the average first innings score in England, we need to use some sort of algorithm that ensures that #jimmyanderson @jimmy9 is awarded a duck in a match he hasn’t batted in. Are you going to tell him? Because I’m not. 6/8
By assessing students based on the available data and our knowledge of them, schools have acted with integrity to offer Centre Assessment Grades that are fair and balanced. Like batting averages. This is not grade inflation 7/8
And finally. Please can everyone stop calling them Teacher Grades? Thanks 8/8
