Professional Judgement and Standards in Educational Assessment



Note: This is a slightly adapted version of a lecture given to Adult Literacy Organisers in Galway, Republic of Ireland in April 2013, under the title: Initial Assessment - What Works? The lecture was organised by The Republic of Ireland's National Adult Literacy Agency (NALA). A video of part of the lecture is available here.

I’m here to talk about Professional Judgement and Standards in Assessment.  Most of what I want to say doesn’t just apply to initial diagnostic assessment in Adult Literacy work, but to teaching in general, and to many other areas of human activity.  It builds on a paper written for my doctorate (Derrick 2013).

I want to start by giving you all some questions to think about.  How much experience do you have as an adult literacy practitioner – hands up: more than ten years?  Five to ten years? Under five years?  Anyone in their first year?  Can I ask the people with more than ten years’ experience – would you say you are good at Initial Diagnostic Assessment?   What is it that makes someone good at it?  For example, is experience essential?  How important is formal training?  How can you learn to get better at it?  Is there a formula, or a recipe for getting better at it?  Is Initial Diagnostic Assessment a science?  Is there, or could there be, an instruction manual for it?

The answers to these questions are vital for sorting out the role of standards, skills frameworks, levels, etc in the work of adult literacy teaching.

The three main propositions of my talk are these:

  • Expert teaching (and within this, expert assessment) is essentially about the exercise of professional judgement in making decisions
  • Professional judgement can be supported by all sorts of tools, resources, measurements, rubrics, standards, etc, but cannot be replaced by these
  • Learning to become better at teaching and assessment is a process of training professional judgement.

30 years ago, Donald Schön, writing about professional practice in general, said this:
In the varied topography of professional practice, there is a high, hard ground where practitioners can make effective use of research-based theory and technique, and there is the swampy lowland where situations are  confusing ‘messes’ incapable of technical solution.  The difficulty is that problems of high ground, however great their technical interest, are often relatively unimportant to clients or the larger society, while in the swamp are the problems of the greatest human concern. (Schön 1983 (1991), p42)

Schön suggests that professionals need to be able to deal with, not just technical, generic problems for which there is a recognised procedure, a standardised routine, but also other, more complex, essentially unique problems for which there is, and can be, no standard ‘correct’ response, and which are therefore amenable only to judgement calls. 

A practical example of this type of problem might be the question of whether to take a child into local authority care, which has to be considered all too often by social workers.  There can be no absolute instruction manual for making a decision like this, because every situation is uniquely different.   

Standard procedures, checklists, etc are helpful, but in the end a decision like this is not reducible to standard procedures – we can only try to ensure that they are made by people highly motivated to make the best possible decision, and who have as much knowledge as possible of the particular situation – and note that ideally this knowledge is not just technical knowledge of the law, of child and of family psychology, etc, but also personal knowledge of the unique pattern of the individual circumstances of the people involved.

Schön’s work is a sustained argument against the dominance of what he calls the ‘technical-rational’ view of professional practice.

Procedures and rubrics are models or hypotheses which always simplify and ‘clean-up’ the ‘messiness’ of real-life situations.  As Goethe warned:
Hypotheses are scaffoldings erected in front of a building and then dismantled when the work is finished.  They are indispensable for a workman, but you mustn’t mistake the scaffolding for the building.’ (Goethe Posthumous (1998), p154)

The scaffolding is useful, even perhaps essential, but it cannot replace the building which it supports.  This it seems to me, is an accurate metaphor for the role of rubrics, standards, technical terminology, pro-formas, skills frameworks, assessment criteria, grade descriptors, diagnostic assessment tests and procedures, and the like.  They have their uses, but ultimately teachers need to make the decisions, because each situation, each learner, is essentially unique.  This is why we should resist talking about education as if it was like mass-production – it is not about using standardised raw materials to produce identical objects.

Addressing educational problems as if they can be reduced to a technical model of one kind or another ignores the local knowledge, practical wisdom and perhaps the long experience of the professional in making similar decisions.  It also ignores the moral dimension: that the professional is motivated to find the right way forward for the clients and others concerned – by which I mean the best and most just response to the situation, not just a technical solution which ‘will do’.   A hypothetical model cannot be relied on to do this because it is a simplification of the situation, and by definition ignores factors in it which in a particular case may be critical.

The holistic argument I am making here highlights the importance in decision-making of local distinctiveness: a nuanced awareness of what is distinctive in the features of a particular locality or situation.  Schön might put it as appreciation of the distinctiveness of each particular ‘swamp’, so as to make informed decisions about appropriate actions.  This view is a critique of the kind of overly-simplistic ‘technical-rational’ modelling of situations that  makes decision-making (for example about whether to build a new supermarket in a country town) appear to be easier, perhaps to the long-term detriment of the locality and its community.  Sue Clifford and Angela King (2009) argue against the homogenising tendency of technical-rational modelling in all aspects of life, emphasising the importance of detail, particularity, patina, authenticity, fineness of grain, divergence, messiness, and quality in the everyday.  This may be caricatured as a conservative critique of regulation through standardisation, of technocratic policies and procedures: but it is an argument primarily against shoddiness, against work in any field that will merely do, rather than reflecting the best efforts of the practitioner.  Research (eg Black and Wiliam 1998, Hattie 2009) tells us clearly, for example, that teachers’ sense of the particularity of situations is central to their understanding of the specific needs of individual students at a given moment in the learning process: this sensitivity is also undoubtedly a foundation of trust and mutual respect between learner and teacher.  It is clearly possible to teach without this detailed knowledge of students and their situation, and perhaps even to teach ‘adequately’, but professional practitioners are deeply and morally concerned about ‘local distinctiveness’ as part of doing the job as well as possible.  Attempting to encapsulate this sensibility in a rubric will always tend to diminish it: minimum standards tend to produce work that simply satisfies the minimum acceptable level of quality. 

In England, much has been made in recent years about the use by teachers of data in their decision-making: it has been suggested, perhaps with some justice, that they have relied too much on hunches and on their intuition, and not enough on ‘objective’ data about their students’ progress.   There is also evidence that teachers and other professionals have sometimes been discriminatory in their practice (for example, having lower expectations of students from particular backgrounds), and this too has been used to support arguments that their work should be regulated within procedural and externally-imposed quality standards.

In my view this is to throw the baby out with the bathwater: it is to argue that the work of teachers is simple rather than complex; it is to argue for the production of an instruction manual for teaching, one consisting of a highly intricate flow-chart, that would provide teachers, whether qualified or not, with a procedure for correctly addressing every teaching problem, or, in terms of our topic today, for correctly the assessing the skills of every new student.

I think that most people would agree that this is not what teaching is about: they recognise that the work of teachers is essentially complex and cannot be reduced in this way.  On the contrary, teachers should be supported to develop their intuition and their capacity to make good judgements, just as surgeons, doctors and social workers do.  So what is the role of all these frameworks, rubrics, standards, pro-formas, tests, etc? It must be to provide information that teachers can use in their decision-making, and in discussing with students their learning goals, their attainments, feedback on their work, and, most importantly, how they can get better at supporting their own learning – in a word, these tools can be used to support formative approaches to learning, provided the information they provide supports, rather than determines, the authentic judgements and feedback of the teacher.  In this way, tools can also support teachers’ own professional learning.

From this perspective, it is not the tools themselves that are good or bad, it is how the teacher uses them that matters.  It is important, though, that teachers are free to determine for themselves how best to use them.  If they are not free in this way, then a particular technical-rational model is being imposed on them, and this may lead to students being sold short, and also to the deskilling and demotivation of teachers.  The problem for policymakers is that education is full of swampy, messy situations, which by definition are hard to predict, control and regulate.  To make the best of them we need teachers who are confident in weighing up situations, highly effective communicators in terms of knowing the kinds of questions to ask and how to listen, expert at qualitatively judging students’ strengths and weaknesses, and motivated to make the best decisions possible about the right courses of action for the student and for the next stage of teaching and learning.  They are very likely to find supporting technical information useful in making these judgments and decisions, and they should certainly pay attention to such data.

It is difficult for policymakers to regulate teachers without imposing limitations on their professional autonomy which may limit their scope for action, as well as reducing their motivation.  But this difficulty does not justify the misconception of learning as merely a technical issue of standard procedures, and teaching as a simple, technical job involving the obeying of standard rules.

If we had time I would invite you all to consider how best we should organise the training and development of adult literacy teachers in a non-technocratic policy environment.  Instead I’ll leave you with an inspiring story of exemplary professionalism that illustrates many of the issues we have been addressing here: on January 15th 2009, a commercial aircraft with 150 passengers and crew on board took off from La Guardia airport in New York.  The pilot in command was 57-year-old Capt. Chesley B. "Sully" Sullenberger, a former fighter pilot who had been an airline pilot since leaving the United States Air Force in 1980, and who is also a safety expert.  During the plane’s initial climb, it struck a flock of Canada geese. The bird strike, which occurred about three minutes into the flight, resulted in an immediate and complete loss of thrust from both engines. When the crew of the aircraft determined that they would be unable to reliably reach any airfield, they turned southbound and glided over the Hudson, finally ditching the airliner in the river about three minutes after losing power.  All 155 occupants safely evacuated the airliner, which was still virtually intact though partially submerged and slowly sinking, and were quickly rescued by nearby ferries and other watercraft.  The recording of the incident makes it clear that, immediately following the bird strike, it was obvious the plane had to land as soon as possible, and there was intense radio communication from the air traffic controllers, concerning availability of nearby runways, and the distance to each one.  After about a minute of listening to this information, the pilot asked just one question about the possibility of landing at New Jersey but then suddenly seems to make up his mind: ‘We are gonna be in the Hudson.’  He then said nothing more, apart from ‘Brace for impact’, until the plane was down.  In interviews afterwards he said that there were two factors that helped him pull off the manoeuvre safely: that the plane’s design was state of the art, and that he himself was 55 rather than 25.  ‘In a sense my whole career had been training for this event’ (Couric 2009).

This story illustrates how all sorts of tools, procedures and data made important contributions to the successful outcome of this manoeuvre, but these would have been irrelevant without the skills, experience and professional behaviour and attitudes of Captain Sullenberger and his crew.  None of these guaranteed success, because off the technocratic map (ie, when the unexpected happens) success is never guaranteed.  The experienced and motivated professional aims to optimise the chances of success.  Even though teachers rarely deal in life or death decisions like the ones Sullenberger found himself taking, in reality the various parts of their job, including initial assessment, are more often off the technocratic map than on it; and this means that the question ‘What Works?’ is misconceived.

Bad Science, Leonardo, and professional learning

Ben Goldacre, the Guardian's Bad Science columnist, is taking a holiday to write a book!  Not Science Fiction, surely, Ben?  I'm sure it will be worth waiting for, but how the hell will we manage in the meantime without you looking after things in the Truth Dept?

Your sign-off column this weekend is a beautifully succinct series of nuggets of wisdom - the most important one in my view being:

'everyone needs to understand how we know if something is good for us, or bad for us. The basics of evidence-based medicine, of trials, meta-analyses, cohort studies and the like should be taught in schools and waiting rooms.'

I fear this is not what Michael Gove has in mind for the central element of the English Bac....




Also this weekend I listened on the radio to a heart surgeon reminding us that while no one is perfect (so things may go wrong for even the most skilled and experienced practitioners of any craft or occupation), it is still true that when working in highly complex situations which in a real sense are unique every time, then more experienced practitioners, assuming they are working with the best available knowledge, are a better bet than relative novices, however brilliant those novices may be.  He was talking in the context of a discussion about the Leonardo da Vinci exhibition, and suggested that surgeons are researching and learning their craft every time they perform their work, just like Leonardo, who never stopped enquiring into nature, never stopped making descriptive notes and drawings, writing down thoughts and hypotheses, and then testing his new ideas to see what would happen; though with him it was in dozens of different disciplines. This is a perfect description of professional learning: practice on its own doesn't produce learning - it needs to be accompanied by reflection, and probably discussion with colleagues (something Leonardo may not have much opportunity for), but also crucially it needs to be made explicit in the form perhaps of writing, or of drawings, so that it can be returned to, re-evaluated, and repeatedly tested to see if it stands up to scrutiny.  If it survives this examination, then it might be reliable enough to be incorporated into future practice.

There's also a mouth-watering review in today's paper of a book on this topic by Daniel Kahneman, called 'Thinking, fast and slow', enquiring into the processes by which people make decisions, how learning contributes to these processes, and how and why even experts make unaccountable mistakes.  I hope it's out in paperback soon.  Meanwhile here's the link for a terrific TED talk by Kahneman on why we should stop using the word happiness!

Professional learning by deliberately cultivating the unexpected

“He that confines himself to one book at a time, may be amused, but is no student.  In order to study, I must sit in some measure in the middle of a library.”

William Godwin, The Scots Magazine and Edinburgh Literary Miscellany, Vol 81, 1818

I take this to suggest that 'students' need to do more than focus on and work directly at the subject of their studies; they must enrich this direct approach with other ideas, stimuli, experiences, so as to allow and encourage surprises, unexpected insights; in short, serendipity.  This might be boringly described as 'reading around your subject', but I think Godwin means something much more than that: something more like Rimbaud's 'systematic derangement of the senses', so as to try to be jolted out of one's preconceptions. 

I am pleased with this idea, as it aligns well with something I wrote recently about the messiness of real teaching and learning (Derrick 2010):

In the dominant model of public sector professionalism today, accidents are seen as prima facie evidence of failure: if unexpected events do occur, it must be due to inadequate preparation or human error. This view of practice assumes that in principle the job and skills of a teacher, social worker, parent, etc, can be defined in detail, without ambiguity, and therefore codified precisely. Regulation and quality assurance of these roles, it follows, is a straightforward process of checking that there is no variation from the code. The training of such professionals is also seen as straightforward, based on a well-defined, unproblematic body of knowledge and an accompanying skill-set that hardly changes over time. This positivist view of practice derives from a positivist view of learning, in some versions almost identical to behaviourism, in which the individual learner is seen as a passive recipient of pre-defined knowledge and skills, which are acquired usually through processes of memorisation and repetitive practice....

There is little room in the positivist view of practice for the idea of teaching as an art, or as a craft, something honed and fashioned over time in the context of a ‘community of practice’, and which takes for granted that changing circumstances and new learners will produce new problems for the teacher, who therefore needs the capacity to respond to new and unexpected situations.  Recent research shows clearly that teachers need to be ready at times to abandon their detailed plans and ‘go with the teachable moment’, not just as a response to difficult situations, but as an optimal strategy when things are anyway going well. Nor can the positivist view encompass the idea of the learning process as active, combining research, creation and re-creation by groups as well as by individuals, with a range of possible outcomes and wider benefits at the level of the individual learner, the group, the community and society in general . It does emphasise the role of the learner in choosing programmes of learning to enrol on, just as a shopper chooses products from the shelves of a supermarket, but this can only be equated with active learning from a reductionist, behaviourist viewpoint....[This] echoes Donald Schön’s famous distinction between different types of professional problem:
In the varied topography of professional practice, there is a high, hard ground where practitioners can make effective use of research-based theory and technique, and there is the swampy lowland where situations are confusing ‘messes’ incapable of technical solution. The difficulty is that problems of high ground, however great their technical interest, are often relatively unimportant to clients or the larger society, while in the swamp are the problems of the greatest human concern.  (Schön 1983)
This view suggests that a crudely positivist philosophy and policy of learning, teaching, and teacher development, whatever its intentions, will be damaging both to society and to individuals. In particular, it will lead to deskilling: it nurtures in professionals a passive, bureaucratic and parochial version of their work, which over time leads to diminishing interest in, curiosity about, and capacity to deal with unexpected situations, or even to imagine crisis scenarios so as to prepare for them. Specifically it leads to diminution in preparedness and of the capacity to make judgements about the best course of action in the difficult, complex situations to be found in classrooms everywhere.
Richard Sennett (1970) argues that everyone needs to experience living and coping with the uncertain and the unfamiliar, of managing and dealing with life in complex and unpredictable situations without being in control of them, in order to reach full psychological maturity. If state-supported education seeks to eliminate the uncertain, the debatable, the unexpected, he suggests that it is condemning people to a kind of passive and frustrating adolescence, whatever their biological age.
Avoiding these problems, and harvesting the full potential of learners and teachers to enrich their practice for the economic, social and cultural benefit of society in general, will mean taking a quite different approach to learning in general, and following its implications through in terms of curriculum, the organisation, funding and accountability systems for state-supported learning, and of course to the formation and ongoing development of teachers.

Montaigne on Education

'I gladly come back to the theme of the absurdity of our education: its end has not been to make us good and wise but learned.  And it has succeeded.  It has not taught us to seek virtue and to embrace wisdom: it has impressed upon us their derivation and their etymology.  We know how to decline the Latin word for virtue: we do not know how to love virtue.  Though we do not know what wisdom is in practice or from experience we do know the jargon off by heart.....our education has taught us the definitions, divisions and subdivisions of virtue as though they were the surnames and the branches of a family-tree, without any concern for establishing between us and it any practice of familiarity or personal intimacy.  For our apprenticeship it has not prescribed the books which contain the soundest and truest opinions but those which are written in the best Greek and Latin, and in the midst of words of beauty it has poured into our minds the most worthless judgements of Antiquity.' (On presumption)

These arguments are very similar to those of modern educators and researchers who say that education has become much too focussed on learning that can be measured easily, at the expense of the education for moral and aesthetic judgement and of values: what is good (allegedly), rather than how to try to be good.  Another indication of how close we are to people of past ages - their worries are our worries too.
