WHEN THE RULER BECOMES THE RACERethinking Assessment, Achievement and Ranking in Ghanaian EducationA Nunyãdume Reflection on What Our Examinations Should Actually MeasureThe Elders of Nunyãdume tell of a teacher who gathered ten children beneath the village tree and taught them to climb.At the end of the year, nine could climb the tree.The villagers celebrated.But the examiner shook his head.“If nine have reached the top,” he asked, “how shall I know which child is first?“So he measured how quickly each child climbed.One reached the top first.Another came second.Someone necessarily came ninth.And the tenth did not reach the top at all.The examiner proudly announced that he had successfully ranked the children.An Elder sitting nearby asked:“But was our purpose to discover who could climb, or merely who climbed faster than another?“The village became quiet.That question, I believe, deserves to be asked about Ghanaian education.What is the purpose of education?Education must certainly identify excellence.Universities and competitive programmes must select among applicants.Scholarships must sometimes distinguish among candidates.Schools with fewer places than applicants require mechanisms for selection.Ranking therefore has a legitimate place in education.But ranking is not education.And ranking is not the same thing as measuring learning.There is a fundamental distinction between the two questions:Has this child achieved the educational standard we established?andHow did this child perform compared with other children?The first measures achievement.The second establishes relative position.Both questions can be legitimate.But they are not the same question.Our difficulty begins when we ask one examination grade to answer both.The BECE ParadoxWAEC states explicitly that BECE candidates are graded using the stanine (STAndard NINE), a method of scaling test scores on a nine-point standard scale with a mean of 5 and a standard deviation of 2. The earliest known use of stanine was by the U.S. Army Air Forces in 1942.More importantly, WAEC explains why: the system was considered appropriate for the dual purposes of certification and selection. WAEC further explains that stanine grading ranks and compares candidates’ performances relative to one another.Indeed, WAEC has explained that BECE does not operate with fixed grade boundaries in the ordinary sense; boundaries may vary according to candidate performance. There is nothing psychometrically illegitimate about norm-referenced assessment.The question is whether we are asking it to perform a task for which a different form of assessment may be more appropriate.Ghana’s curriculum philosophy increasingly emphasises competencies and performance standards. Our National Pre-Tertiary Education Curriculum Framework describes assessment as determining how far a learner has attained necessary knowledge, skills, attitudes and behaviours, and emphasises that, assessment should provide meaningful feedback about progress toward defined performance indicators. This presents us with an intellectually important question:If our curriculum is increasingly standards- and competency-oriented, should our principal assessment philosophy not also tell us whether those standards and competencies have actually been achieved?The Difference Between Achievement and RankingImagine that Ghana decides that every child completing JHS should be able to solve a particular level of mathematical problem.We invest in teachers.We improve textbooks.We introduce technology.We support struggling pupils.And eventually 90 per cent of our children master that competency.That should constitute a national educational triumph.A criterion-referenced assessment can tell us:Nine out of every ten Ghanaian children have attained the required mathematical competency.A norm-referenced system asks a different question:Which children performed better than the others?Even in an outstanding cohort, somebody remains at the bottom.Conversely, if an entire cohort performs badly, relative ranking can still identify its highest performers.That information is useful for selection.It is considerably less useful for determining whether Ghana’s educational system is actually succeeding.The distinction is fundamental:A nation should measure its children principally against what it promised to teach them, not merely against one another.The Mental-Health QuestionWhy should the Chief Executive of the Mental Health Authority enter a discussion about educational assessment?Because examinations do not merely produce grades.They produce experiences.They influence identity.They influence family expectations.They influence anxiety.They influence self-worth.And, for some young people, they appear to determine their entire future.A child can easily move psychologically from:“I performed poorly in an examination”to:“I am a failure.”Those statements are profoundly different.One describes an outcome. The other defines a human being.An educational system must be demanding. Standards matter. Excellence matters. Competition will sometimes be unavoidable.But unnecessary competition should never masquerade as educational measurement. Educational psychologists, psychiatrists, teachers and policymakers should therefore ask not whether examinations cause some anxiety, that is inevitable, but whether the architecture of assessment unnecessarily transforms learning into perpetual social comparison.What, then, should Ghana do?I propose neither the abolition of BECE nor the abandonment of ranking.I propose something more conceptually coherent:Separate Certification from Selection.Certification should answer: “What has the learner mastered?”At both BECE and WASSCE levels, Ghana should progressively establish clearly defined, criterion-referenced competency standards. A grade should communicate meaningful information such as:Advanced proficiency.Proficient.Developing proficiency.Basic attainment.Below expected standard.The boundaries should be anchored, as far as psychometrically feasible, to what candidates demonstrably know and can do.The nation could then meaningfully compare educational outcomes across years.If Mathematics proficiency rises from 45% to 75%, Ghana should be able to celebrate that achievement without requiring some predetermined proportion of children to occupy lower categories.Selection should answer: “Where does the learner rank when places are scarce?”Where 20,000 qualified children compete for 5,000 places, ranking becomes necessary.Use an appropriate standardised score, percentile, placement index or other psychometrically defensible mechanism for that particular purpose.But call it what it is: selection.Do not confuse it with mastery.Thus a learner could receive:Mathematics: Proficientand, where necessary for competitive placement:National/placement percentile: 78thOne tells the family what the child knows.The other tells the system where that child stands in a competition for scarce places.BECE and WASSCE should share one assessment philosophy; not necessarily identical gradesThis is where I would modify the proposition that started this discussion.I would not insist that BECE and WASSCE must necessarily use identical grading symbols. Their purposes and developmental stages differ.I would insist on something more important:From basic education through senior high school, Ghana should have one intelligible philosophy: achievement is measured against defined educational standards; ranking is separately reported when selection requires it.That creates continuity without forcing artificial uniformity.The Two Princesses of NunyãdumeThe Stammering Linguist of Nunyãdume tells of two young princesses whose educational journey did not follow the familiar road. When other children travelled the conventional path towards the BECE, these two were educated for a period within the compound of the Chief Linguist. There were no school bells to announce the beginning of lessons. There were no positions in class to tell them whether they were first, fifth or fiftieth.But there were books.There was discipline.There was curiosity.There were expectations.There were examinations of another kind, the daily expectation that what had been taught must be understood, questioned and applied.And eventually, when the princesses left the compound and entered the larger educational world, something interesting happened.The absence of a BECE certificate had not meant the absence of learning. They progressed. They competed. And eventually, both gained admission to study medicine in Ghana.If Odomankoma, the Creator, grants them life and good health, they may in the coming years emerge as young doctors serving their country. The Elders of Nunyãdume did not tell this story to argue that Ghanaian children should be homeschooled.Neither did they suggest that two princesses constitute scientific evidence.Two children cannot establish national educational policy.Nor should an educational opportunity available to one family automatically be assumed feasible, appropriate or equitable for millions of Ghanaian families.The Elders told the story because it forced Nunyãdume to confront a more fundamental question:Is passing through every conventional examination necessarily synonymous with learning?The experience of the two princesses suggests that the answer cannot simply be yes.For an examination is an instrument for measuring education. It is not education itself.A weighing scale can tell the farmer something about his harvest.But the scale did not grow the maize.Likewise, an examination can tell us something important about what a child has learned.But sitting an examination did not, by itself, produce the learning.And ranking children tells us something else again.It tells us how one child performed relative to another.It does not necessarily tell us whether either child has attained the standard Ghana expected them to achieve. That distinction is fundamental.The Elders therefore asked:“If ten children reach the top of the tree, does the fact that one arrived tenth mean that child cannot climb?”Surely NOT.And if none of the ten reaches the top, does declaring one of them first mean that the village has successfully taught its children to climb?Surely NOT.Therein lies the distinction between achievement and ranking.Our educational system must first determine whether the learner has acquired the knowledge, competencies and intellectual tools we promised to teach.Where opportunities are scarce and selection becomes necessary, we may then ask who performed better than whom.But we should never confuse the second question with the first.For the ultimate purpose of education cannot simply be to determine which child stands above another. It must be to enable every child to stand.And perhaps that is the lesson the two princesses unknowingly taught Nunyãdume:There may be many roads to learning, but every road must eventually be judged by what the traveller knows, understands and can do, not merely by whether the traveller passed the same milestone as everyone else.The role of educational psychologistsI believe Ghana’s educational psychologists should occupy the intellectual centre of this conversation. This should not become a political contest between those “for” and “against” WAEC. WAEC performs an indispensable national and regional function.Nor should politicians alone determine the answer.This is fundamentally a question of psychometrics, developmental psychology, pedagogy, curriculum design, equity, and public policy.Educational psychologists should help Ghana determine:What exactly does each examination purport to measure?Are grades valid measures of those constructs?What competencies constitute satisfactory attainment?How should standards be set?How stable should those standards remain across cohorts?When is norm-referencing appropriate?When is criterion-referencing preferable?What is the psychological effect of high-stakes ranking?How do socioeconomic inequalities influence apparent merit?How should school-based assessment complement external examinations?And how can assessment produce information that improves teaching rather than merely sorting children?NaCCA’s own mandate includes developing national curriculum and assessment standards and reviewing national assessments, making such a multidisciplinary reconsideration institutionally compatible with Ghana’s existing educational architecture. From examination system to learning systemThe Elders of Nunyãdume say:“When the farmer weighs his harvest, the scale does not make the maize grow.”Examinations are scales.They are important.They tell us something about the harvest.But weighing children more frequently does not educate them.Ranking them more precisely does not necessarily make them more competent.Our real national questions are harder:Can they read with understanding?Can they reason mathematically?Can they interrogate evidence?Can they communicate?Can they collaborate?Can they create?Can they solve unfamiliar problems?Can they disagree without becoming enemies?Can they use knowledge ethically?Can they continue learning after the examiner has left the room?If the answer is yes, education has succeeded, even if another child happens to be better.If the answer is no, a Grade 1 cannot rescue the system.A National Assessment CompactI would therefore propose that Ghana convene a technically led National Assessment Compact, bringing together NaCCA, WAEC, GES, the Ministry of Education, universities, Colleges of Education, educational psychologists, psychometricians, teachers, parents, students, mental-health professionals, and employers.Its mandate should not begin with: “Should we abolish stanines?”That prematurely prescribes the answer.It should begin with:“What information should Ghana’s national examinations provide about every child, and for what purpose?”Only after answering that question should we choose the measurement instruments.That is how science should inform policy.The Child Is More Than the RankThe Elders of Nunyãdume return finally to those ten children beneath the baobab tree.The examiner had arranged them from first to tenth.Then the Elder asked the child who came ninth: “Can you climb?”The child answered: “Yes.”“Then why,” asked the Elder, “have we spent the whole afternoon discussing the eight children who climbed before you?”There lies the philosophical heart of the matter.Ranking tells us who came before whom.Assessment should first tell us who can climb.And education must ultimately teach every child to climb.Ghana should therefore pursue an assessment system rigorous enough to recognise excellence, sensitive enough to identify difficulty, fair enough to accommodate different pathways, and intelligent enough to distinguish achievement from competition.Let us measure our children against high standards.Let us identify exceptional achievement.Where scarce opportunities require ranking, let us rank transparently and scientifically.But let us never confuse a child’s position in a distribution with the measure of that child’s potential.For the Elders of Nunyãdume say:“The fact that one bird flies higher does not mean the others have forgotten how to fly.”Our educational system should tell every Ghanaian child: how well they have learned, what they can do, where they need help, and how they can improve.Only after that, where necessity demands it, should we ask who came first.That is the difference between an educational system designed principally to sort children and one designed to develop them.And Ghana must choose development.
