DEDICATION. To the unknown, but very large, number of young people who have been damaged by the award of wrong exam grades, in the hope that this will not happen in the future
STATISTICS. Over the decade from 2010 to 2019, a total of about 70 million GCSE, AS and A-level grades were awarded following each year’s summer exams in England. • Of which around 17.5 million were wrong. • Yes,17.5 million. • That’s about 1 wrong grade in every 4.
FOREWORD. Foreword by Dr Robin Bevan Headteacher, Southend High School for Boys NEU Past National President, 2020-21. old standard! Well, maybe not! For many years England’s GCSE and A-level qualifications enjoy an international reputation as world-leading. This book forensically analyses grades
1. EXAM GRADES ARE IMPORTANT. A'Level and GCSE grades can affect life chances, yet the regulator Ofqual's own statistics show that 1 in 4 grades can be wrong. This book gives all the evidence, discusses the implications, and – most importantly – offers some solutions
2. EXAMS IN ENGLAND. Deals with GCSE, AS-Level and A-level exams, exam centres and schools, awarding bodies, the regulators Ofsted, DfE, and Ofqual, the House of Commons Education Committee, marking, grade structures, grade boundaries, criterion referencing, cohort referencing, norm referencing
3. ARE EXAM GRADES 99.2% ACCURATE? Edexcel’s claim that grades are 99.2% accurate on results day (taken from Pearson-Edexcel’s website), assesses comments made about grade reliability by School Standards Minister Nick Gibb, Ofqual's Chief Regulator Glenys Stacey and Ofqual's Marking Consistency Metrics
4. TWO IMPORTANT WORDS: ‘ACCURATE’ AND ‘RELIABLE’. What does ‘accurate’ mean in the context of exams? Can exam marks ever be accurate? Looking at how marking by different examiners can alter the grade. The reliability of a grade is the probability that an originally-awarded grade is confirmed
5. SUMMER 2016: OFQUAL MAKE IT HARDER TO APPEAL. Until 2015, candidates unhappy with their grades could – for a fee – request a re-mark. But in May 2016, Ofqual changed the rules for challenges and appeals, intentionally denying access to an expert second opinion. Why did the regulator do that?
6. OFQUAL’S FIRST MEASURES OF GRADE RELIABILITY. In 2015, Ofqual carried out an extensive study in which the entire cohorts of GCSE, AS and A-level scripts, in 12 subjects, were marked twice: firstly, as normal, by an ordinary examiner
secondly, by a senior examiner, whose mark was designated 'true'
7. OFQUAL’S REAL MEASURES OF GRADE RELIABILITY. Using Ofqual data, the author calculates the reliability of mathematics grades is 96%, chemistry 92%, physics 88% etc right down to the lower arts subjects such as English literature (58%), history (56%) and combined English language and literature (52%)
8. WHY GRADES ARE UNRELIABLE. Three reasons why marking (marketing error) is not the problem. Instead, there is a more powerful explanation – fuzziness. Ofqual admit: 'There is often no single, correct mark for a question'. So marks may legitimately vary, causing valid but 'fuzzy' results
9. NOVEMBER 2018 TO SUMMER 2019. Newspaper sized on Ofqual's admission about grade unreliability, with reports in the Daily Telegraph and Sunday Times. Ofqual insists that marking error is to blame for any problems but stresses that results and grades are overwhelmingly accurate
10. 2020: CAGS AND RANK ORDERS. Due to the Covid epidemic, the UK government cancels all physical GCSE, AS-Level and A-Level exams and replaces them with an Ofqual algorithm, which is crude. 'The details of the algorithm were both important and missing from Ofqual’s Guidance documents.'
11. THE GREAT CAG CAR CRASH. On results day, Thursday 13th August, and over the next few days, progressively more stories surfaced on some ‘peculiarities’ in the algorithm’s results. Yes, overall, nearly 40% of CAGs were down-graded, but some were up-graded, sometimes very strangely
12. THE AFTERMATH. Were the CAGs right? Or fair? In a word, no. Or rather, some were, and some weren’t. I hope that most – if not the vast majority – were
but some definitely weren’t, and no one knows how many. Furthermore, Ofqual proved to be hugely obstructive in letting anyone find out
13. SUMMER 2021: THE TAGS. With Covid-19 once again obstructing physical exams, Ofqual oversaw Teachers Assessed Grades. 'The process was a mess in principle, and made even worse by the problems of rounding and statistics. But overall, Ofqual designed and implemented a totally flawed process...'
14. NINE WAYS TO DELIVER RELIABLE AND TRUSTWORTHY GRADES. Presents 14 solutions in order to offer a comprehensive ‘menu’ of possibilities, so as to stimulate the debate about which is indeed the best and most effective: the best and most effective among 15 possibilities
15. FIVE FUNDAMENTALLY DIFFERENT WAYS TO DELIVER RELIABLE AND TRUSTWORTHY ASSESSMENTS. Five more solutions to the problem of delivering reliable grades – or rather ‘assessments,’ for as will be seen, the last solution suggests a different way of representing students’ achievements on their certificates
16. OVER TO YOU… Reliable, trustworthy, grades are not just a public ‘good.’ Our young people deserve them. After 11, 12 and 13 years of school, the end-game, the key prizes, are those certificates with those grades. What a kick in the teeth it is for so many grades to be wrong
APPENDIX - FUZZINESS, A DEEPER DIVE. The central concept in this book is fuzziness – my word for the fact that different, equally qualified examiners can legitimately give the same script different marks. Here I define and describe fuzzy exam grades
