The availability of places in special schools is unevenly distributed through the country. Marked variations can even occur between neighbouring boroughs. Thus, one London borough in 1977 placed ten times more children in schools for the maladjusted than another (DES, 1978a). Consequently, special school places have never provided evidence about the numbers of children with special educational needs. To see how the Warnock Committee formed its conclusions we have to look at evidence from studies of larger groups of children.
Disturbing Behaviour
The most widely quoted investigations are the National Child Development Study, and those carried out by Professor Michael Rutter and his colleagues on the Isle of Wight and in an Inner London borough. The National Child Development Study included all children born between 3rd and 9th March, 1958. On the basis of the teacher version of Stottâs Bristol Social Adjustment Guide (1963), 64 per cent of children were rated as stable, 22 per cent as unsettled and 14 per cent as maladjusted (Davie et al., 1972). The same study showed that 13 per cent of children were thought by teachers to need special educational help, but only 5 per cent were in fact receiving it.
Rutter and his colleagues asked teachers to complete a behaviour questionnaire (Rutter, 1967) on the pupils they studied. In addition they interviewed the childrenâs mothers, and on the Isle of Wight, but not in London, the children themselves. 19 per cent of children were rated as deviant in the Inner London borough on the basis of the teacherâs questionnaire results, compared with 11 per cent in the Isle of Wight. Using all the available questionnaire and interview data, 25 per cent of Londonâs 10-year-olds were said to be showing âclinically significantâ signs of psychiatric disorder, compared with 12 per cent on the Isle of Wight. The term psychiatric disorder was used to include âabnormalities of emotions, behaviour or relationships which are developmentally inappropriate, and of sufficient duration and severity to cause persistent suffering or handicap to the child and/or distress or disturbance to the family or communityâ (Rutter and Graham, 1968).
An interesting incidental observation from the Isle of Wight study was the small overlap between children whose parents were concerned about their behaviour and children whose teachers expressed concern (Rutter et al., 1970). This was partly attributable to teachers reporting more behaviour problems of a broadly antisocial type, while parents tended to report a larger number of withdrawn children. Children whose parents complain about their behaviour at home may have special needs. Whether they have special educational needs is another question altogether.
Two explanation may be put forward for the low overlap between behaviour problems at home and at school, as reported by parents and teachers. One is that parents and teachers interpret similar behaviour in different ways. âQuietnessâ, for example, may be considered a virtue by some teachers who may be more concerned about openly disruptive pupils. Parents, on the other hand, may see quietness as an indication of lack of confidence or of anxiety in social situations. Another explanation is that children behave in different ways in different contexts.
Both explanations are valid. Both draw attention to the teacherâs role in attributing special educational needs to a child. Teachers vary between themselves in how they interpret behaviour. A healthy extrovert to one teacher can be a thoroughly noisy, disruptive nuisance to another. Similarly the child that one teacher in an open plan class sees as quiet, but sensitive and creative, may be seen as an immature, withdrawn little baby by another. Disturbing classroom behaviour, in other words, is not a problem because of any objective criteria in the behaviour itself, but rather because of the effect it has on teachers.
All experienced teachers, moreover, will recall children whose behaviour has changed dramatically with a change of teacher. In the same way a change of school can be accompanied by a change of attitudes and of behaviour. At home, parents recognise that their childrenâs language changes according to the company they are in; expressions and pronunciation considered unacceptable within the family may be necessary for social acceptance in the street or the playground. Thus, a teacherâs statement that a childâs behaviour indicates a need for special educational help has to be seen in terms not only of the teacherâs own values and attitudes, but also in terms of the childâs behaviour in a particular context.
An observation from a follow-up to the Isle of Wight study revealed a slight increase in the prevalence of psychiatric disorder at age 14 compared with four years earlier (Rutter et al., 1976). This was not, however, attributable to any important increase in the rate of overtly disruptive behaviour of most immediate concern to teachers. More important, perhaps, just over half the pupils assessed as showing signs of psychiatric disorder had first presented problems as adolescents. Fewer than half had been disturbing their parents or teachers four years earlier. This observation has two implications. Firstly, as the Warnock report recognised, the problems presented by many pupils are transient. Secondly, concentrating provision for pupils with special needs on the younger age-groups would be of limited value, even if all the pupils concerned could be âtreatedâ successfully. This is not the case, nor is there any way of identifying reliably pupils who will disturb their teachers towards the end of their school careers. Even if these pupils could be identified, there would be no way of telling what their educational needs would be, let alone how they should be met. We shall return later in the chapter to the confusion surrounding the concept of special educational need on account of disturbing behaviour. Firstly, though, we need to look at the prevalence of learning difficulties.
Learning Difficulties
Nationally, special schools for pupils with moderate learning difficulties, formerly known as ESN(M), account for roughly 1 per cent of school age pupils. This tells us nothing, however, about the number of children who might be experiencing learning difficulties. To see why, we need to consider the range of problems subsumed under the blanket term learning difficulties.
The 1944 Education Act and subsequent regulations (Ministry of Education, 1945) did not define criteria for ascertainment as ESN. Subsequent publications, though, made clear that special schools for ESN pupils should cater predominantly for those with a low IQ, generally assessed as below 70 or 75 (Ministry of Education, 1958, 1961). We shall return to the uses of IQ tests shortly. The point here is that the controversy was associated with two questions:
The way in which most IQ tests are constructed ensures that roughly 2.5 per cent of the population will obtain a score below 70.
Virtually all special schools for children with moderate learning difficulties have always admitted a disproportionate number of boys and a substantial minority of pupils with relatively high measured intelligence (Ministry of Education, 1958). Further, they have in many areas aroused understandable anger and suspicion by admitting a disproportionate number of children of Caribbean origin (e.g. Coard, 1971). The implication is that they have been used as convenient places for problem pupils, and not simply as the most appropriate place in which to meet the needs of pupils with moderate learning difficulties.
Even without the confusion surrounding criteria for admission to a special school for children with moderate learning difficulties we would still be no nearer an idea of the prevalence of learning difficulties. The predicted figure of about 2.5 per cent scoring below 70 on an IQ test is a purely statistical artifact of the way most of these tests are constructed, a point to which we return shortly. We therefore need to look at the number of children believed to have learning difficulties in ordinary schools.
Yule et al. (1974) noted that 8 per cent of 10-year-olds in the Isle of Wight and 19 per cent in an Inner London borough had a reading age at least 28 months below their chronological age. In most cases the poor reading ability was associated with low measured intelligence. In other words, their reading level could be predicted from knowledge of their IQ. These pupils were regarded as backward readers. Nearly 3 per cent of the Isle of Wight pupils and 10 per cent of the London pupils were reading significantly below the level predicted by their age and IQ. These pupils with specific reading retardation overlapped with the backward group. Their special educational needs, though, were more specifically confined to reading, since they did not, on the whole, have similar problems in mathematics.
Multiple âHandicapâ
The four criteria noted so far in defining learning difficulties which indicate special educational need are an IQ below 70, reading backwardness, specific reading retardation and psychiatric disorder. At least one of these conditions applied to 16 per cent of 10-year-olds on the Isle of Wight (Rutter et al., 1970). More than one condition applied to a quarter of this 16 per cent, or 4 per cent of the total.
Warnock refers to these criteria as âhandicapsâ. Certainly, they have been taken as evidence both in the report and in subsequent discussion, as evidence of special educational need. It is therefore worth asking whether there was anything in the least surprising in the evidence that up to 20 per cent of children may have special educational needs, as defined in the report, at some stage in their school career. It is also worth asking whether the criteria themselves can meaningfully be seen as valid.
